Element14 blog published some settings that should reduce memory usage in Firefox. I’m currently testing those settings, So I don’t know yet if they work or not. I like Firefox as it’s a very stable application. But it’s frustating sometimes, when you look at process memory usage: sometimes Firefox end using about 200 MB. This Memory problem with Firefox explains why I’m still using Maxthon. Maxthon’s memory usage never exceed 50 MB (it’s what I noticed from my experience). I tried many settings n the Firefox config windows to reduce those “memory leaks”. But none were really efficient. Let’s see if those new settings works. The Firefox Memory Usage FQA contains also useful information about known leaking Firefox extension.
