I have not noticed the memory/CPU issue quite as often since I upgraded to 1.0.2.

I agree.. I just installed the update about a week ago and it has gotten better. Not perfect, but better.

I get this issue with Firefox and Maxthon often. The more tabs I have open, the more likely the browsers will start hogging CPU/memory--which makes sense.

Help! I am suffering a similar problem to those described in this thread (at least I think its similar...). Firefox is causing my PC to crash periodically. When this happens, none of the windows will respond, and even the task manager takes ages to shut the open Firefox windows. I thought this was a problem with my PC, but have seen several similar threads to this one describing problems like mine. I have the latest vesion of Firefox, and used to love it, but this is now a daily occurrence. I am seriously considering returning to IE . Does anyone know how to fix or mitigate this problem

I've always had this problem, I solved it by installing an app called "process tamer", it reduces the strain an app (any app) puts on your system.

You might want to try that!

FWIW, here is the download link:

I've mainly noticed the problem with Firefox slowing due to problems with extentions. Try starting Firefox via the "Safe mode" item in the Start menu, and then remove or update the extentions (vai the Tools|Extentions menu). Extentions that were built for older builds of Firefix are particularly problematic.

The only way to stop Firefox from taking up all the CPU is to close it and open it back up. Doing some tweaking with the About:Config doesn't change much except that it takes a bit longer before Firefox gets to over 100,000k. This is definitely some kind of a memory leak where the more tabs you open, the worse it gets. Closing the program and re-opening it starts it back to a lower level.

I am now using a somewhat less bloated and functional browser that doesn't nearly get as big as Firefox. It's called OffByOne ( http://www.OffByOne.com )and for many people, they won't like it because there aren't many features and many plugins are not supported. But, for simple browsing, it's fine.

I actually love how much less CPU and memory it uses.

With 2GB RAM in my laptop, I really don't care how much memory FF uses

I have the same in my desktop, but things really get out of control when a single app starts claiming 1.4Gb of memory

Do you mean memory instead of CPU?

I don't think it's a memory leak; minimizing the app seems to release most of the memory.

I am so pleased that people are using Firefox. I remember several years ago few wanted to hear about using anything different from IE and Outlook. Things are much improved when more of use are using non-Microsoft, open source software.

Well, you have to admit that several years ago the open source browser alternative sucked...

For me, the fact that Firefox is open source is only an incidental benefit. I use it because I really think it is much better than IE. In work, I have to use IE and I really miss Firefox.

Thanks for this ScottC. I am trying it out and I have not had another problem so far.
