After applying security update 3.6.18 i started having this problem. I had this problem earlier but it only happened after several days Firefox was opened constantly. Now i have this problem several hours later after launching Firefox.

Here is a picture of high RAM usage

I have Flash disabled.

What is going on? Should i reinstall Firefox 3.6.18?

Have you any particular reason for using an older version of Firefox.

Whilst I rarely use firefox 3.6 now, and do not know the answer I will comment that the now unsupported firefox 4 did have bad memory problems in some cases. Some of those problems were addressed in firefox 5, and others are addressed in Firefox 7, which is due out on the Aurora channel next week.

You could consider upgrading to a newer version of firefox. If you need firefox3.6 only for limited use you could consider using Firefox portable, alongside a newer version of Firefox.
