Firefox memory Leak?

This morning I woke my computer up (sleep mode) and was astonished to see memory usage at 54%! I have 8GB RAM and I've never seen it this high.

I checked Task Manager and saw that Firefox was using 1.8GB and still climbing; about every second it increased by a few Bytes, like clockwork.

There were also three instances of that plugin-container process. Why 3?!

I thought Firefox v4.+ was supposed to have gotten rid of their memory (leak?) problems.

Here's a snapshot and I hope somebody can give me some idea of why it's doing this. TIA!

@Not Myself:
A lot of great information here!
Thanks!

Hello rap33042. I'll suggest you to do this in Task Manager.
View->Select Columns and there select CPU Time. After the process is started it will count a time,so you should easy know what processes and when.
It should look like this:

You're welcome!

I've started eliminating add-ons in Firefox to see if I can narrow down the culprit.

I'll let you know what I come up with.

Firefox sometimes runs for almost 1 GB of RAM on my Win 7 x64 computer.

All right-
I've gotten rid of the add-ons in the snapshot and it seems to have gotten rid of the memory problem.
I don't really know at this point which add-on is the problem:

You should have a look at this;
