Get ready for most powerful and end of No.4 in Firefox version. If everything goes right way (i.e. if developers don’t find any particularly problematic bugs), then the final version of Firefox 4 should be released March 22, according to a message posted on Firefox’s official forum.
“As of now, there are no known issues that would stop us from shipping RC1 as final. March 22nd is the day we would ship,” writes Mozilla’s Damon Sicore.
The release candidate of Firefox 4 was launched one week ago; we’ve used it a lot during that time and found no significant bugs. Still, if a significant issue should arise before March 22, the ship date for the final version would be moved and we’d get an RC2 (release candidate two) version instead.
Some of the features from Mozilla firefox 4 are listed below
1. Tabs on top of the browser.
As with Opera and Chrome, Firefox 4 tabs are placed by default above the search bar instead of below it.
2. App Tabs
Mozilla 4 allows you to turn any tab into an “App Tab” by right-clicking on it and selecting “Pin as App Tab.”
3. Switch to a Tab via the Search Bar
Start typing the address of a website that is already opens in a tab, and Firefox 4 will suggest an option to switch to that tab, even when it’s in a different open window. If you’re someone who opens more tabs than you can remember, this feature can help prevent repeats.
4. Tab Groups (also known as Panorama):
It is a great way to organize and group your tabs. In the Tab Groups window your App Tabs are represented by their site’s icon on the right side of each tab group.
Enter the Tab Groups view by clicking the List All Tabs button at the far right side of the tab strip and selecting Tag groups
For Tag groups,the keyboard shortcuts, you can use Ctrl + Shift + E.
