Firefox 1.0.7: better memory management?

I love Firefox, but one thing that’s causing me grief is its memory leakage. On my gentoo box, Firefox 1.0.6 would quickly eat up to 55% of my available memory. I had to kill Firefox every two days to get my machine working. I’ve upgraded to 1.0.7 yesterday, and it runs smoothly using only 25% of my available memory (according to “top”). Given that my browser is arguably the most important software application running on my machine and given that I’m unlikely at any one time to run two browsers, I don’t care if firefox uses up to 25% of my memory, but please, no more. When I’m not browsing the web, I’ve got to do real work like research and teaching. Interestingly, the release notes don’t mention anything about improved memory usage. Also, my Mandrake box (running 10.1) doesn’t seem to have this problem, nor do my windows boxes, irrespective of the Firefox version number. Anyhow, I’m crossing my fingers, hoping that Firefox will be well behaved this time.

  1. I updated my Firefox to 1.0.7 for about 1 month, but I don’t see anything better. I still have to close it from time to time.

  2. Interesting Ben. We’ll see how it goes, but the day is almost over, and I haven’t seen the very damaging leaks I see usually.

    The thing is, with gentoo… they may be applying some patches on top of the official release.

  3. I have the same problems with 1.0.7 that I haved with previous versions. I use a lot of tabs, and with every tab the memory use of Firefox increases (obviously). But when I close most tabs, it doesn’t seem to release the memory. Also when memory use is high enough, sometimes Firefox uses 97-99% CPU permanently. Sometimes the process doesn’t stop when I close the browser, and I have to kill it.
    I really hope all this will be fixed sometime!
    (This refers to Firefox on Win XP Pro on a Notebook with 1.5GHz Pentium Centrino and 768MB Memory)

  4. The reason i like firefox is because it’s EASILY flexible, extendable, configureble, usable, but the thing is that it uses a LOT of memory (it once reached 1GB of memory consumption omfg).

    Opera is very fast, but lacks all the features i mentioned for firefox above. It doesn’t have easy-to-find-and-install extensions like superdragngo, html tidy, tab plus mix etc. It’s not easily customizable in various aspects (mouse gesture, additional tab functions, etc)
