I’ve always had a severe memory leak issue with Firefox. FF will slowly grab more and more memory often hitting 1/2 GB with only 3-4 tabs open.
I use a ton of extensions and I read a couple sites where they listed off a bunch that were known to contribute to memory leaks. For whatever reason I zeroed in on Forecastbar Enhanced as a likely suspect. Well, low and behold, it seems to have fixed a major contributor to my problem. There are probably others and I’m disabling the ones that I can live without.
I’m sort of suspecting that it could be a combination of extensions because I use Forecastbar at work and it doesn’t eat away memory like at home. Oh well, I guess ya can’t argue with success.
