Mozilla has just got over with the release of Firefox 3 today, and I don’t think the development team is going to take a break any where soon. They like keeping themselves busy. The alpha version of Firefox 4 on their FTP is no surprise to us. Now they’ve got themselves busy with Firefox 3.1 and are planning to release it in mid-July. Firefox 3.1 will be based on Gecko 1.9.1 and will be designed to bring to the table some of the features and functionality that were cut from Firefox 3.0.

Here’s an early look at some of the features that will be included in the next version of Firefox and are planned to be included in the first Alpha release:

• A new visual tab switching feature will work like the Alt+Tab switching feature in Windows (in other words, you can see thumbnails of open tabs). If you want to check out this feature before it’s officially added to Firefox, you can download the Ctrl+Tab extension for Firefox 3.0 now.
• Download history will be added to Places.
• Support for bulk bookmark tagging and tag auto-completion.
