User-Agent: Mozilla/5.0 (X11; Linux i686; rv:2.0b11) Gecko/20110203 Firefox/4.0b11 Build Identifier: Mozilla/5.0 (X11; Linux i686; rv:2.0b11) Gecko/20110203 Firefox/4.0b11 When I start Fx it takes initialy about 250 MB, then this number grows by about 100 MB as tabs load (I have about 35 tabs opened). I don't usually shut down PC, so next day I see that Fx memory consumtion reaches a point at about 1GB and that's a half of all RAM installed. All numbers are taken from htop utility, RES gauge. Now trying to open a link from external application causes Fx to freeze. My system starts swapping (at least I hear HDD doing something), browser window stalls and the only way to stop this is to send SIGTERM to the application. It seems to me that there's a memory leak or fragmentation somewhere. Reproducible: Always Steps to Reproduce: 1. Start Fx, load some pages in tabs. 2. Leave it, say, for 24 gours. 3. See it ate way too much RAM. Actual Results: Fx memory consumption grew 2-3 times comparing to a moment when it was leaved. Expected Results: Firefox shoud not consume additional memory (in such amounts) when it's not active. In spite of my CPU architecture is 64-bit I run 32-bit version of openSuse Linux and Firefox.
Max, I am setting this as a duplicate of Bug 631733 which has been extensively discussed and which I think also covers your issue. Feel free to changed it back to Unconfirmed if you think I am not right.
Yes, looks pretty much like a duplicate. Thanks, George.
