ABOUT: WHAT YOU DONT KNOW ABOUT FIREFOX

about: A simple prompt without any parameter will display the Mozilla “about” information. Since it’s accessible from the top menus as well, it’s not quite a hidden feature.
about:buildconfig Obviously, it will show the build platform configuration and parameters
about:cache Will display info and statistics regarding your disk’s cache, including the name of your cache’s directory and a list of the entries you can find there. By default, Firefox doesn’t allow you to view the cached webpages, so this can be an useful option.
about:config Oh look, many many info. Indeed, it’s the most complex and meaningful of them all. Careful on what you plan to change here, your browser won’t run properly after if you play with the wrong things.
about:plugins Of course, what is Firefox without it’s powerful extensions? This option will display detailed information about all the plugins installed for Mozilla Firefox.
about:credits It’s time to give the credit to whoever deserves it. There’s an alphabetically sorted list of all the people that gave their contribution to the development of Firefox.

about:Mozilla This is a weird thing. It will display the so-called “Book of Mozilla”. Something similar was present in Netscape too. There’s actually no real book although the quotations might give you that impression.

GOOGLE SHUTS NOTEBOOK,CATALOG SEARCH,DODGE BALL,JAIKU AND VIDEO SERVICE

For google services microblogging platform Jaiku, mobile location service Dodgeball, Google Catalog search, and Google Notebook today is the death day.Though google didn't announce the reason the strategy looks simple to shut down extra costs in this recession times.Not only services google is also planning to cut 70 engineers as a part of the cutting costs.
Thuough notebook will be online all the development will be stopped and browser extension is not supported any more.Google Video will also be downgraded, with users no longer able to
upload video to the service, being forced to use YouTube instead.Google Video, Google’s original foray into online video before it acquired YouTube is switching off uploads; videos currently uploaded to the service will remain. No word yet as to whether YouTube will now accept video longer than 10 minutes, one of Google Video’s still strong selling points today.

Google will no longer actively develop the Jaiku codebase, the service itself will live on thanks to a dedicated and passionate volunteer team of Googlers.Google have decided to shut down the Mashup Editor, currently in limited private beta, in favor of the more powerful App Engine infrastructure.Existing Mashup Editor applications will stop receiving traffic in six months, and we hope you will join our team in making the exciting transition to App Engine.

WHATS NEW IN CHROME 2.0

Google has released the beta release of its Chrome browser.The new build is given the version number 2.0.156.You can download the latest build from here.Since it is the first beta release you would expect a lot of changes to its previous version. The team at Google has taken the feedback received from the first official release, and made changes accordingly.So lets take a look at what's new in new version.

Form Autocomplete. Google Chrome remembers what you've typed into fields on
web pages. If you type in the same form again, it will show any
previous values that match what you've typed so far. You can disable
Form autocomplete on the Minor Tweaks tab of the Options dialog.This is like the basic form autocomplete available in Firefox
or Internet Explorer.

Full-page zoom. Previously, page zoom (Ctrl++ or Ctrl+-) increased or decreased
only the text on a page. Zoom now scales everything on the page
together, so pages look correct at different zoom levels.

HTTPS-only browsing mode:This new feature lets users add “force-https to your Google Chrome
shortcut” to only load Web sites with valid security certificates.
“Sites with SSL certificate errors will not load".

Spell-checking improvements. You can now enable or disable spell checking in a text
field by right-clicking in the field. You can also change the
spell-checking language by right clicking. To enable spell-checking in
a language, add it to the list of 'languages you use to read web sites'
in the Fonts and Languages dialog ([Wrench] > Options > Minor
Tweaks > Fonts and Languages).

Autoscroll. Many users have asked for this and (thanks to our WebKit update), we
now offer autoscrolling. Middle-click (click the mousewheel on most
mice) on a page to turn on autoscroll, then move the mouse to scroll
the page in any direction.

Docking dragged tabs. When you drag a tab to certain positions on the monitor,
a docking icon will appear.  Release the mouse over the docking icon to
have the tab snap to the docking position instead of being dropped at
the same size as the original window. Docking positions are:

• Monitor top: make the dropped tab maximized.
• Monitor left/right: make the dropped tab full-height and half-width, aligned with the monitor edge.
• Monitor bottom: make the dropped tab full-width and half-height, aligned with the bottom of the monitor.
• Browser-window left/right: fit the browser window and the dropped tab side-by-side across the screen.
• Browser-window bottom: fit the browser window and the dropped tab top-to-bottom across the screen.

Import bookmarks from Google Bookmarks. The [Wrench menu] > Import
bookmarks & settings... option now has a Google Toolbar option to
import Google Bookmarks. The bookmarks get imported into your Other
bookmarks folder. The bookmarks are not kept in sync; the import
process simply reads in the current set of online bookmarks.

New SafeBrowsing implementation. SafeBrowsing is now faster, more reliable, and uses the disk less often.

Use different browser profiles. You can start a new browser window that
uses a different profile (different bookmarks, history, cookies, etc.).
Use [Wrench menu] > New window in profile. When you create a new
profile, you can name it and add a shortcut to your Desktop. 

Update the V8 Javascript engine to version 0.4.6.0 (from 0.3.9.3).

New window frames on Windows XP and Vista, supporting windows cascading and tiling, and other window-management add-in programs.

Make your firefox run faster

1.Type "about:config" into the address bar and hit return. Scroll down and look for the following entries:

network.http.pipelining network.http.proxy.pipelining network.http.pipelining.maxrequests

Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.

2. Alter the entries as follows:

Set "network.http.pipelining" to "true"

Set "network.http.proxy.pipelining" to "true"

Set "network.http.pipelining.maxrequests" to some number like 30. This means it will make 30 requests at once.

3. Lastly right-click anywhere and select New-> Integer. Name it "nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it acts on information it receives.
