Sorry, but not that I've seen in any version of Firefox I'm using. Presently ~15 at work (Ubuntu 11.10) and Iceweasel 10 at home. On an 8 GB system, I'm constantly reviewing my browser memory usage and killing/restarting browser sessions on account of memory usage. iceweasel VIRT presently 2163MB.
Sorry, but that's totally nuts.
Mozilla have been claiming "we've solved the memory leak problem" about as long as Microsoft have been claiming "we've solved the virus/security problem", or so it seems. With about the same level of credibility.
I wonder if there are large differences based on usage patterns.
I just finished entering a comment above suggesting people should give it another try; I have 100 or so tabs open and 500MB footprint after using it all day, with version 13 (I just stick with the release update channel) in win7.
In my experience they've very clearly fixed whatever the main memory issue was that affected my experience -- but not yours. Though -- the windows versions may get a bit more testing....
Hmm, I'm no expert. But AFAIK open memory mapped files are counted towards a process's virtual memory (as displayed by utils like 'top' and 'ps). Dunno if FF uses memory mapped files extensively.
There's a utility called 'pmap' that you can use to display the memory mapped files and subtract it from the total etc.
Finding out how much memory a program is using is surprisingly tricky to compute. Good luck.
