Ever had this problem in Firefox, where you are on a page doing something important, and you accidentally click on a bookmark (in the bookmark tab) causing your current page contents to be lost?
I just found an interesting plugin for FF today that solves this problem: Tab Mix Plus. With this plugin you can force FF to open bookmarks in a new tab. Not only that it gives you a whole lot of “tab control”. FF tabs become more usable and informative with this addon. Check it out, I am sure you will like it too.
