GOOGLE CHROME:

Larry Page and Sergey Brin under the umbrella of Google and it was created in September 1998.

Features:  Light weight, colorful, peaceful, easily browse facility, contains own task manager, great facility...And so on.....  contains its own task manager in that, we can see the options like, memory, cpu, network..Contains information how much memory the website occupies and how much the cpu and network usage can be observe.  Because it is new release the add-ons are not available. May be Google provide the add- ons later. at presently not available.  Main advantage of this browser is default searching facility. if type something in the link bar...the browser automatically shows corresponding searching results. If you type website address in the link bar if it is available, the browser will find the site and displays. Otherwise it will search related information and displays like Google search engine. Just type in the link bar that's it what we have to do.  Another advantage of it is, we can see the most visited web sites in the tab. new Incognito mode is a Google Chrome browsing mode where your subsequent web searches are recorded in your Google Web History. In this case, if you want to make sure your searches are not stored in your Google Account, you'll need to pause your Google Web History tracking. Browsing in incognito mode only keeps Google Chrome from storing information about the websites you've visited.  Encoding facility, text zoom are also available in this browser. This is super fast browser.  Searching history facility is available in this wonderful chrome. This option is available right up corner.  View source, debug java script, java script console are available with chrome at developer option. We can observe the download history and the process in the bottom when downloading something. If the add-ons are released the wonderful browser will occupy the first place.  You can find only the back and forward button and refresh button and the address bar along with the above mentioned two control menus in the entire browser. If you want to add in the homepage button, you can do so from the customize option available.

Drawbacks:  Because it is developed in 2008.It is available with beta version as usual. It‘s requirement is winxp service pack 2.Google developed this product for windows only.  For some websites like hub pages…its not supported browser, because many products download software are developed and supported for existing browser like IE, , and so on. it is also available for vista also. It is not available for users immediately.  Another disadvantage of Google chrome is its history search box will fetch all types of data - even text from HTTPS-protected financial sites (dslreports.com and tgdaily.com).  Like IE and Mozilla and opera there is no menu bar shows file ,edit, tools and so on rather we can customize in customize Google chrome option.

 Slow startup.

INTERNET EXPLORER:

Microsoft, August 1995.

Features:

Speed

IE seems to be noticeably faster than old versions, which users will welcome. The actual speed difference may be in milliseconds, but the faster downloading could help Microsoft win back some customers.

Updated Content

An RSS feed on your favorites bar will indicate to you any updated content on sites that you have listed as favorites. This information shows up as a green icon in the upper right hand corner, which alerts you to this update so that you can access it immediately.

Similar Sites

IE will suggest to you five similar sites to the ones you are currently viewing. This will enable you to find more information quite easily if the site you are on does not give you enough details.

Integration

Internet Explorer integrates with other Microsoft applications like Outlook Web Access and can show presence. This is a big plus in company environments where a number of persons are online at the same time.

Stability

If one window in a tabbed environment crashes, the other tabs do not crash simultaneously, and this is a big plus point. Internet Explorer has been able to open a window with tabs in their

3 E. Commerce. BBA 6 A [WEB BROWSERS] Zarak Khan previous versions as well, but this new ability to contain the crashing of any one site is a new feature.

Compatibility

IE has become more compliant to than its previous versions. It has a compatibility button which you can press if sites that have lower web standards do not display properly. This then enables the browser to open the site in the more compatible, lower version.

Drawbacks:

Similar Sites

Internet Explorer does indicate to you up to five sites that are similar to the one that you have opened. But, this is restricted to the better known sites which have better page rankings. However, a user is generally already aware of such sites. This additional list can only be of help if the sites listed are some of the more unfamiliar ones that are not so frequently visited. This would broaden the web experience.

Memory Requirements

IE recommends a minimum of between 64 MB and 512 MB of memory. However, this seems inadequate and is better served with a memory of at least 2 GB. This would mean that home users and small business users may be forced to go in for costly upgrades if they are not to find the performance of IE disappointing.

Page Display of Sites

Sites that have still not complied with the latest web standards may not display easily or correctly in IE. The compatibility button does not easily open all such sites, and you may be forced to wait for the upgrade of the site itself before you can view it properly.

Microsoft Playing Catch Up

IE really seems like an effort by Microsoft to catch up with other browsers like Firefox but no real attempt at anything new. So, whether this will help Microsoft retain its market share is something the market has to decide.

Heavy to Load

Internet Explorer is quite heavy to load, and smaller home users may have to watch their hard drives before they can decide on an upgrade to IE.

Even with the advent of tabbed browsing, which allows you to keep multiple Web pages open in the same window, Web multitasking, can be a pain. You have to constantly click back and forth among tabs if they contain fast-changing material you check often, like the status of your friends in social-networking services, or updates to news feeds.

OMNIWEB:

The Omni group, 1995.

Features:

. Separate window form editing

Click the square in the upper right corner of multi line form fields to open it in a separate window. This helps when you wish to add lots of text to an area which is very small and you want to see all of it at once. This feature also allows you to enter tab characters.

. Workspaces

Groups of windows and tabs in them. A user can have multiple workspaces for different web research topics and quickly switch between them with a key shortcut or menu choice.

. View :

By clicking on this button in the toolbar, one can quickly view all the links contained in the page.

. Ad blocking:

Omni Web uses a powerful pattern match ad blocking feature to stop images from loading from servers matching the pattern. It is also possible to block images that don't originate from the current server you are browsing and to block images that match common advertisement sizes.

7 E. Commerce. BBA 6 A [WEB BROWSERS] Zarak Khan

. Shortcuts

allows one to type a key word or phrase to open a certain web site or begin a specific web search.

. Site preferences

Omni Web allows you to specify preferences that apply to specific websites. For example, if you adjust the font size on a given web page, the adjusted font size will be used on all other pages of the same site. Preferences are saved automatically and retained between browsing sessions.

Drawbacks:

 Slow.

 User interface mistakes.

 Page Display of Sites.  Heavy to Load.  Large memory Requirements.  Updated Content.  Bad security.

 Tabbed browsing.

SAFARI:

Apple Inc., January 2003

Features:

Improved Web Inspector A good web inspector is extremely important to most web developers. Many people still prefer , which is an extension for Firefox, but the Web kit inspector has improved dramatically in the last few years.

8 E. Commerce. BBA 6 A [WEB BROWSERS] Zarak Khan

CSS Inspector In 5, the web inspector has an improved CSS inspector panel, which lets you jump directly to a rule definition in the source file.

DOM Inspector The DOM inspector is much improved, now allowing you to add attributes to DOM nodes in your document, remove nodes, and edit nodes as HTML, which lets you edit the entire tag as if it was a source file . Resource Panel The Resources panel is also improved, letting you see all HTTP redirects, along with full header information, including the HTTP status code.

JavaScript Inspector The JavaScript inspector now lets you disable all breakpoints with a single click, and if you hover over an element while on a breakpoint, you can see the actual object values of what you are hovering over. This will be extremely useful for debugging purposes.

Timeline Panel Safari 5 now has a new Timeline Panel, which provides information about everything that the browser is doing while you browse. This includes loading data, parsing it, laying it out on screen, and rendering it. Very cool for working on the performance of your website or application.

Audits Panel Another added panel is the Audits panel, which much like the popular YSlow and Google Page Speed extensions for Firebug suggests ways for you to improve the performance and compatibility of your site.

Console The last change to the Web Inspector is that a separate panel for the JavaScript console has been created. This is nice because it allows the console to take up the entire height of the Web Inspector rather that the small part that it used to. It is still available in the old location, however, for convenient access while looking at another panel. For more information about the updates to the web Inspector, check out this post on the Web kit blog.

Drawbacks:

 High Memory usage.

 Slow startup.

 No add ons.

 No download notification.

 No Phishing protection.

CAMINO:

Features:

Tab Overview. Phishing & Malware Protection Tabbed Browsing Improvements. Download Notifications. Annoyance Blocking. Keychain Support. AppleScript Support. Spell-checking. Feed Detection. Session Saving.

Drawbacks:

 No Add ons.

 User interface mistakes.

 Memory Requirements.  Use more memory than other browsers.

 Slow startup time.

SWIFTFOX:

Jason Halme, 2010.

Properties:

Binary code optimization The Swiftfox executable has been compiled with the highest level of compiler optimization, rather than optimization for binary size. The compiler supports various flags that will perform different optimization levels during the compilation process. Firefox is compiled with -Os flag

10 E. Commerce. BBA 6 A [WEB BROWSERS] Zarak Khan

(which enables only the optimizations that don't increase code size and also a few optimizations designed to reduce code size), while Swiftfox is compiled with -O3 flag, which basically turns on all available optimizations. Binaries incorporate additional instruction sets supported by and also optimization specific to the architecture. Moreover, Swiftfox has been compiled with a newer version of the compiler program (GCC v 4.0.4), while Firefox uses v 3.3.2.

Increased security Swiftfox offers better protection against buffer overflow attacks as a result of using -D_FORTIFY_SOURCE=2 while compilation. Firefox has been compiled with an older version of GCC, which doesn't support this.

Removed or disabled feature is not included, allowing Unicode fonts to remain supported, but without certain extra features provided by it. Pango is an open source computing library for rendering internationalized texts in high quality, integrated into GTK+ 2. Moreover, Ipv6 DNS lookups are disabled.

Changed default preferences values HTTP pipelining is enabled by default. This is a technique in which multiple HTTP requests are written out to a single socket without waiting for the corresponding responses but unfortunately, it's only supported in HTTP/1.1, not in HTTP/1.0. The pipelining of requests results in dramatic improvement in page loading times, especially over high latency connections such as a satellite or wireless Internet connection. However, this preference can be enabled in .0 or one can use an extension called Fastefox, which provides a GUI to adjust these settings

Drawbacks:

 Data URIs are not separately cached from their containing documents (e.g. CSS or HTML files) so data is downloaded every time the containing documents are re downloaded.  Content must be re-encoded and re-embedded every time a change is made.  Data is included as a simple stream, and many processing environments (such as web browsers) may not support using containers (such as multipart/alternative or message/rfc822) to provide greater complexity such as metadata, data compression, or content negotiation.  Base64-encoded data URIs are 1/3 larger in size than their binary equivalent. (However, this overhead is reduced to 2-3% if the HTTP server compresses the response using gzip[citation needed]).  Data URIs make it more difficult for security software to filter content.

OPERA:

Opera software ASA

Features:

 One set of third-party speed tests concluded that Opera 9.5 was indeed faster than Internet Explorer 7 and prerelease versions of Firefox 3 and Safari 3.Technology website ZDNet's speed tests in early 2008 showed that out of Internet Explorer 7, Safari 3, and pre-release versions of Firefox 3 and Opera 9.5, Opera was the fastest in some areas, but the only browser that Opera clearly outperformed was Internet Explorer. However, as of version 10.5, Opera features a new JavaScript engine, as well as a new vector graphics library, which together significantly increase Opera's overall rendering speed.

 Opera includes built-in tabbed browsing, ad blocking, fraud protection, a download manager and BitTorrent , a search bar, and a aggregator. Opera also comes with an e- client called Opera Mail and an IRC chat client built in.

 Opera includes a "Speed Dial" feature, which allows the user to add up to 25 links (or more, by editing the speeddial.ini file) shown in thumbnail form in a page displayed when a new tab is opened. Thumbnails of the linked pages are automatically generated and used for visual recognition on the Speed Dial page or can be modified using Opera Image Dial Generator. Once set up, this feature allows the user to more easily navigate to the selected web pages.

 Opera supports Opera Widgets, small web applications that start from within Opera. Alongside Widgets, "User JavaScript" may be used to add custom JavaScript to web pages. Greasemonkey support is limited, and there is no interface to manage scripts or toggle 'Greasemonkey-on' functionality.

 Opera is extensible in a third way via plug-ins, relatively small programs that add specific functions to the browser, and as of Opera 11, third-party extensions. However, Opera limits what plug-ins can do.

Drawbacks:

 No page progress bar

 isn't supported by all sites and that includes Google Mail

 Not as customizable as Firefox...but maybe that's better for beginners

12 E. Commerce. BBA 6 A [WEB BROWSERS] Zarak Khan

 Initial load up is very slow.
