Even going back to version 0.7, Firefox has always been a memory/resource hog.

I complained about one of their versions. Firefox Support said it must have been one of the extensions I was using. Since then, I and others have remarked about the excessive memory usage.

It is a persistent problem that they can’t seem to fix.

My Firefox 3.5.4 frequently consumes 160,000K and up. If I run video or open very many tabs, I have to shut Firefox down completely to free memory.

Now that I have three tabs open, it’s hovering at just over 96MB and slowly climbing.

Me too.

Nearly every day.

I will continue reading past your post in the hopes someone has a solution......
