Windows 7: Firefox 5.0 Beta

ok zigzag I found some leak tools but they all look hard to use so havent loaded one yet. Since bartab isnt available for ff4 yet (probably best addon ever made) I enabled this option to a value of 0 "browser.sessionstore.max_concurrent_tabs"
This sort of provides part of what bartab does and doesnt load all the tabs into memory at startup, I then left it for some hours.
It started off using 192 meg ram. with 1 tab loaded. others in background not loaded.
After the hours of uptime (dont know exactly how long but I think about half a day or so) it was around 340meg ram usage. I then click on a different tab and bam down to 250 meg usage. Since I now installed ramback addon I clicked on clear cache and it went down to 195meg again. However where was this 60meg cache been used? because about:cache which I had already checked showed no ram cache been used, so either thats buggy and it was been used or there is a ram cache not shown in about:cache.

I have now started it again with all tabs loaded and when it gets above a gig ram usage I will hit the clear cache button and see if all the gig or so of usage is cache.

Update Tab Mix Plus to the dev build .386
It helped make Firefox's memory consumption a lot more reasonable for me - highest ever was 800 odd MB instead of the 1.4GB which I had previously seen. Has something to do with the way TMP handles session management.

seems was no need, it just prompted me to update to 386 anyway as thats the now stable version of TMP.

so restarted on 386 TMP and will see what diff that makes.

Before the restart it was using 1 gig (with all tabs loaded in memory) I hit clear cache and it dropped to 740meg so it didnt recover it all. Prior to hitting clear cache, ram cache usage was just 29meg in about:cache so was a hidden 230meg of cache data somewhere in ram. This issue is compounded by the fact bartab doesnt work on ff4.

I am not confident of the TMP upgrade solving this as I had the memory leak with no extensions installed. But will report back on the effect.

Googling reveals dozens if not 100s of mem leak reports for ff4, so it looks conclusive from where I sit anyway.

I guess you've already tried the usual reset to defaults, new profile, update flash and stuff. I hope you find your problem, for me it was TMP, I didn't know a stable build was released as I've been using dev build from their site for 2 weeks now .. but try having a look at it. Helped me big time! It's decent for me - 21 add ons, 3 windows and around 30 tabs were 580 MB .. much better than when I had .385 (used to average 900mb easily).

its already running, start ram usage 240meg, current 700 meg.

In ff 3.6 (with more plugins) the ram usage and leaks is only a fraction.

Wow! Crazy RAM usage! Safe mode makes any difference? Are you using recent video drivers? FF felt sluggish with any driver prior to 260.99 for me. Worth a shot. If it's still a problem, I guess it's IE9 or Chrome then .. a browser isn't worth so much effort! Oh btw, you've not applied any reg tweaks, right?

Ironically since this is a ff5 thread I think I am going to test ff5 and see if that has the same leaks, maybe its already fixed in ff5, because I think they wont fix a ff4 issue only ff5.

The system in question has next to no reg tweaks, the only thing I tweak on windows 7 systems usually is desktop heap and some mouse hover settings but I have not done that on the test pc as I dont run enough apps to saturate the default limit.

Before I try ff5 I may try to see behaviour with one site loaded at time but will be a slow process.

heh bug report filed to ff team, I left it for 3-4 days and when I went back to the machine I had a crash report on screen, FF when crashed was using 77% of system memory. (4 gig).

Will be trying ff5 now to see if this is fixed on that.
