Re: Stall/high cpu usage with youtube, high tab count, win7 firefox

If you disable NoScript, does the issue subside?
FlashGotters and NoScripters of all lands, unite!
It does. With NoScript enabled, 'about:performance' stalls or is slow to update, tab clicking is delayed for seconds, and youtube playback and window rendering stutter or are very delayed. Disabled, all interactions and rendering are very rapid. (Using the link and instructions I provided 3-4 replies back.) It isn't a matter of minutes as had happened before but it is now in the 10-20 second range which is higher than experienced in recent releases of FF/NS.
On demand yes. So by just restored session it means that less than 10 tabs are loaded which is also shown in about:performance. 5 windows one of which has over 7000 tabs while the rest are smaller. Previously the window with 7k tabs had notably longer freeze than windows with less tabs, but with FF 82 there doesn't seem to be notable difference anymore.
But that is expected, isn't it.and a window in incognito mode ... using the incognito mode window removes them if I don't read them before closing firefox)
Only restore tabs when I need them (or however it reads in FF).on demand
Yes, it's the reason I use it, to avoid adding to the number of tabs carried over from session to session..therube wrote: ↑Wed Oct 21, 2020 3:21 pmBut that is expected, isn't it.and a window in incognito mode ... using the incognito mode window removes them if I don't read them before closing firefox)
Private Windows are not expected to be restored (from Session Restore) on a FF restart (or even if closed during the same session).
Yes, and this is the reason I STILL have 11.000 tabs: to check (or read) one and the close it, I have to load it, adding to my PC problems with Firefox and noscript. And a lot of these tabs have movie clips or other youtube content inside...Only restore tabs when I need them (or however it reads in FF).on demand
IOW, you are not restoring 11,000 tabs when starting FF.
Only 1 tab, per window (10 windows noted above), so only 10 tabs actually load (fully).
The others will only load (fully) "on demand" - if you actually click the tab in question.
I have 10 firefox processes going on at any given time (1 "Main Thread", 8 "Web Content" and 1 "webextensions"). When I reboot the PC and stant firefox the CPU and memory use is low (I never did the addition of the total cpu and memory use, but for the entire PC and all the ongoing processes usually is less than 20% (3 GB) at the start, and I seldom have only Firefox going). With use the memory occupied by the main thread and webcontant increase, but in a reasonable way (at this moment, after days from the last reboot and heavy use, each webcontent is around 1GB, MainThread is 2GB). Webextension stays low even after days, it's at around 0,1 GB now.Also worth knowing, would be (Firefox, & total "firefox", not just a particular process of it's) CPU & memory usage during these times.
It's very easy to reach that number if:And I'll also note that over time, different browser versions have worked better/worse with... huge numbers of tabs... And as you can no longer expect consistence between any FF release, no telling what may or may not happen, work better/worse... And, if you were to bring up 11,000 in bugzilla, they'd simply laugh that off & say it's not realistic. ["sorry, but that's just absurd", is a direct quote I've gotten.] (I'm a tab user, but don't believe I've hit those kinds of numbers.)
