How to Determine which Firefox Add-ons are Using the Most Memory

After 24 hours my Firefox uses nearly 2 GB RAM. So I have to restart Firefox once a day.

How can I find out, which of my plugins has this memory leaks?

Any possibility to get a list of memory usage by plugin?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Which version of Firefox? I have encountered a memory leak with clean installations of Fx 9.0.1. Then again, 4GB of RAM was being filled up within 5 minutes. – iglvzx Jan 9 '12 at 17:05
Firefox hoards RAM on its own (Chrome does it, too). Often, it's not cookies but dynamic pages, i.e. if you keep GMail or Facebook open 24 hours. – dnbrv Jan 9 '12 at 18:50

A big culprit could be if you have a tab hoarding problem. Keeping multiple tabs open for extended amounts of time will eat away at your memory for sure.

If that is the case, I suggest the following extension called UnloadTab:

This extension stops your multiple tabs from running at the same time. When you click on a tab that hasn't been touched in a while, it just reloads it.
