Firefox 78.0.1 does not remove closed pages from memory - lags and high RAM usage

After updating from 77 (I think it was 77.0.2?) to 78.0.1 I started noticing terrible firefox performance after a few minutes of browsing. My standard browsing habit consists of launching browser with 1 pinned tab and 1 home page (so 2 tabs only), then opening 5-10 tabs from my bookmarks, checking pages then closing them and leaving only 1 pinned page open. In firefox 78.0.1 after doing this (opening and then closing multiple tabs "to the right" using new context menu added in 78) my ram usage does not drop. It goes from 2.4GB (system only usage) to 5.0GB and does not drop after closing tabs. However when I open 10-20 tabs again RAM usage does not rise (maybe slightly, like 5.3GB). So it looks like firefox has multiple tabs stored in ram and opening new tabs just rewrites that memory instead of allocating new one. I have 8GB of ram so 3GB of usage from 1 open tab is crazy. I think it was 500-900MB before. I also have terrible lags because of this - browser hangs up every few seconds for few seconds. I had trouble writing this post with 2 tabs open because of 3.3GB ram usage! Restarting browser helps - ram uasge rises from 2.4GB to 3.2GB only (800MB for 2 tabs) but every new opened and closed tab seems to stay in memory. For example if I open 10 more tabs except for 2 that always open so I have 12 tabs I have 3.6GB memory usage. After I close them it slowly drops to 3.5GB instead of returning to 3.2GB. It does not matter how I close tabs - using right click context menu (close other tabs, close tabs to the right), using X on tabs, or using add-on to close all tabs except for pinned ones. They always remain in memory somehow. PLS fix this ASAP.

P.S. I also tried checking about:performance menu but there is nothing interesting here. It says that 2 opened tabs and addons use 100MB of memory which is not true because browser at this moment uses 1060MB.

Update 1: I also tested safe mode. 3,4GB of PC RAM usage on firefox safe mode start. Opened few tabs, ram usage goes to 4.2GB. After closing all tabs except for 1 ram usage start to SLOWLY decrease but it stops at 3,7GB. Ram usage drop was really slow like 10-30 seconds. It should be instant after closing tabs.

HI,

it's a problem that's been around for years, yet i never got an appropriate answer, so i'm asking here:

The longer i keep Firefox running, the slower my whole system gets and the slower firefox itself gets - up to a point (generally like about 10 hours or so) where everything becomes so slow, i have to manually shut down Firefox via the Task Manager. All that seems to be independent from the fact whether i actually do something in Firefox or not.

So i don't know what Firefox actually does while i'm away that kills my whole system, but i'd really like to know and i appreciate any help!!!

THX in advance

Hello,

I recently had to switch back to my laptop and noticed that firefox is micro-stuttering (missing a couple of frame at worse) at a somewhat regular interval. Which is very noticable and head-ache inducing when watching a youtube video.

I tried to disable every plugins that I have, switching to a new profile, setting browser.sessionstore.max_tabs_undo and browser.sessionstore.max_windows_undo to 0, closing everything in the background, clearing cookies caches and etc.

Nothing worked, I noticed that disabling window's "Hardware-Accelerated GPU Scheduling" helped. With it on I've got a very regular micro stutter (every 10 seconds) whereas with it turned off I "only" get a microstutter once every 20/30 ish seconds. Therefore I suspect some shenanigans with optimus drivers but I don't know for sure how to confirm. I tried to force firefox to use the integrated gpu with nvidia pannel but it didn't help.

I would have capture a video to show off the problem but everytime I start recording (with lenovo's nerve sense capture software) the problem totally disappears !

Anyone have any ideas about what could be happening / how to diagnose more precisely the problem ? Thanks for reading.

specs :Windows 10 (x64), Firefox 78.0.1 (x64), Intel Core i5-7300HQ, optimus GPUS : Intel HD Graphics 630 + NVIDIA GeForce GTX 1060 (Max-Q)

The 76.01 update of Firefox has completely broken the audio function in my browser. Youtube and Yahoo Finance specifically. I have not checked further. Yes I know Windows 7 is not supported by Microsoft, but Firefox has claimed that it would support Windows 7 indefinitely. Yesterday when I opened Firefox a message said that audio and video might not work if I did not have DRM enabled. I checked and saw that I had DRM enabled, but audio did not work. A button in the message said Enable DRM, I clicked the button anyway. No audio. I restarted Firefox, no audio. I restarted my computer, no audio. I opened Chrome and everything is working fine. I did not even okay this update. I have my preferences set to NOT automatically update. it seems like Firefox is ignoring my preferences. Firefox should provide an instant downgrade to the previous version that supported audio. In the past I have downgraded a few times until things were working smoothly, but it's a headache. Now I understand Firefox makes it even harder to do that. I may just switch to Chrome permanently.

I've been using firefox for many years now without any trouble. But just last week, I found it takes a very long time to load even a simple web page.

I've already tried "refresh firefox", and uninstalled all plugins, and it is still slow. I am using Firefox version 78.0.1 (64-bit) and using Windows 10.

hi, Firefox 77.0.1 (32-bit) in Windows 7 crashed completely and i had to taskkill /im firefox.exe /f

this has happened a few times before, and up to this point Firefox could always restore the last session when reopened (maybe minus any last minute pages or any pages causing errors)

this time, the browser restored many pages, some of them are pages/tabs that i had already closed days before the crash (that i do not need) and also it didn't restore tens of tabs that i had opened afterwards (that i need) the missing tabs are not tabs that i opened right before the crash, they were open for at least one or two days in other words, the session restored is an earlier/older version and not the session i was having during/near the crash

is there something i can try to restore the correct session fully? would there be another restore file i can use? thank you for your time

Just thought you ought to know about this bug so you can fix it. It's never happened with any previous version of Firefox, so something in your latest update isn't playing nice with Roundcube and has to be fixed.

I used to take print to study contents offline and I almost always use Mozilla as a browser. Recently I noticed that I was unable to print a full page in a simple website. Understandable that firefox team has been busy working upon the print bugs, but the page and the website I am referring to is Purely HTML and CSS; and for some reason firefox cuts out the rest of the pages from print except for the first.(i.e) to say it prints only the top part of the page..

Though I work with Ubuntu I have crosschecked with Win8.1 and TOR version of firefox which had the same shortcoming, with the website I was referring to. However other browsers such as the Safari and Chrome seem to do fine with this regard. Kindly check for yourselves and let me know if I am going wrong somewhere. Also please Avoid recommending any add ons to accomplish the task at hand.

The thing is the website I was referring to is of very simple make and may help the team to shoot the bug if any, with an easier test case such as this.

With love and Thanks

I am running MACOS 10.15.5 on a MacBook Pro. Up until recently Firefox has worked perfectly. Now, and for maybe the past week or so, I get the pop-up error message "Firefox.app" can't be opened. No other indications or messages.

I have removed and reinstalled the app from the Firefox 77.0.1.dmg file. Still have the issue. I get the same msg when attempting to start Firefox in safe mode. I thought at first this issue may be due to the upgrade to 10.15.5 from 10.15.4, but a family member's Firefox works perfectly on 10.15.5. I actually don't remember when the jump to "5" from "4" actually happened. I have checked the forms and found nothing relating to this specific error. Perhaps I missed it.

I have attempted to recover Firefox from an earlier (6/2/2020)Time Machine backup which I believe was prior to the "5" upgrade, but the message is still the same.

Any help/suggestions would be appreciated. Thanks.

When I have Firefox running, Windows is freezing occasionally. Sometimes it is freezing every few minutes; sometimes a couple of times per hour. I find errors in the Windows event log from the ESENT service which correlate to the freezing events (see attached image).

The freezing events seem to occur more often if I have more Firefox tabs open.

I have tried running Firefox with add-ons disabled and have uninstalled and then reinstalled Firefox and the in both cases the freezing events still occur.

The freezing events do not occur if I use MSIE or Chrome, but I would prefer to use Firefox.

I have checked Device Manager for errors - there are none. The S.M.A.R.T. utility reports all OK for my C drive.

I am looking for advice on how to resolve this problem.

This seems to happen wherever the data entry box is located on the page. Disabled all Add-ons to see if that caused the refresh. Did not help.

Added the separate search box to the task bar, did not help. Brought up DuckDuckGo page for their search box, same thing, did not help. Cannot enter anything on the browser while in Tablet Mode.

Note: DO NOT HAVE THIS PROBLEM WITH MICROSOFT EDGE OR GOOGLE CHROME BROWSERS. THE TOUCH KEYBOARD STAYS ACCESSIBLE FOR ENTRY ON BOTH OF THEM, SO IT'S NOT WINDOWS OR HARDWARE.
