For those of you who have used Opera, you might miss its great sidebar control features. Firefox is more of a toolbar type of guy and the sidebar’s mostly used up by add-ons and the default options to access the bookmarks or history.

I haven’t really tried out this add-on previously but now that I’ve installed it, I think it’ll stay on my system for now. All-in-One Sidebar lets you access Firefox’s panels in the sidebar - bookmarks, history, downloads, extensions and themes, page info and page source.

You can also reposition the sidebar quickly from one side to the other. And it’s got loads of enhancement features like assigning widths and icon sizes for a neater browser. For keyboard ninjas, you can even customize shortcuts for panel access to your command.
