Why does Firefox keep telling me that it is using too much memory, (eg: 235MB) and I should restart Firefox?

Lately Firefox has been popping up a warning while I am on the internet saying, that "Firefox" is using too much memory. It suggests shutting down Firefox and restarting Firefox. It also told me how much memory that is in use at that time. It is usually about 235MB or more. What is normal memory use for Firefox to use while I am on the internet? Does high usage mean that some other person is trying to get into my computer?

You appear to have AVG installed:

From reading on the internet, it appears that when there is a spike in memory usage, AVG "interprets" that as a memory leak, possibly caused by malware. AVG could be incorrect concerning that assumption. Maybe they are being a bit too conservative about memory usage; just my opinion.

The decision is yours to turn off the "advisor" or leave it on.
