All-in-One Sidebar
"AiOS lets you open various windows as sidebar panels, and quickly switch between them. So it put an end to the window chaos! In addition to bookmarks and history it opens dialogues such as downloads, add-ons and more in the sidebar."
Firesizer - [you can do this with Java scripts instead...unless have have Java resizing disavled.
"Allows you to resize the window to specific dimensions."
I use 1024x1000 since most sites are still designed for 1024x768. No point fullscreening Firefox on a 22" monitor.
