Firefox addons

One of the reasons i chose to move from IE to Firefox is the availability of tons of addons. These are the addons I use

Tree style tab : This makes the tab bar vertical and the new tabs will be opened as children to the current tab making the tab bar look like a tree. Its very useful for me because I hardly close the browser (unless it crashes). So by the end of day there'll be lotta tabs sitting in the tab bar and its very difficult to find a tab or close a group of tabs. Vertical bar makes this job easier. When the parent tab is closed, u can choose to close children as well. Since the bar is vertical with tabs kept one below the other, there is more room for tab headings which you can read. The bad part is vertical bar takes up some part of the screen. But it doesnt matter if ure using high resolution .

All in one gestures :  While browing through web pages ill be mostly using mouse.  This addon enables all the keyboard shortcuts with mouse gestures. Takes a while to get used to it. But its funny to use. Not recommended for laptop touch pads as well as non-optical mice.

Down them all  : Download accelerator. Integrates very well with conext menus.

You tube video download :  Shows up links for normal and HQ video download.

 

Sage: A simple reader for RSS feeds. Nicely integrates along with the Tree Style tab.

Xmarks: Synchronizes the bookmarks among multiple machines. The best part is addon supports inter browser synchronization. You can even synchronize passwords and open tabs.

Let me know if there are any good ones that can be added to the list.
