Firefox Support Forum

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.

Middle-click to open in new tab is wildly inconsistent, even on the same link on the same site in the same session. I'd say it works about 10% of the time after the recent 78.0.1 update. I verified my mouse's middle-click operation at https://www.onlinemictest.com/mouse-test/, so I know the middle-clicks are registering and the problem is with Firefox.

Hello, I can't think of the best way to word this, but I want to make sure that certain bookmarks on my bookmarks tool are not moved or replaced by newer bookmarks that I add to it. Make sense? Thank you!

Hi, my firefox started to crash regularly for a few months. I have seen it crash while on idle, while changing tabs, while opening ne tabs... i.e. no repetable pattern. Morever, I couldn't figure out the reason since all the crash reports turned different reasons for each crush. It has now become hourly crashes which really started to affect my workflow. Could you please help?

When I select "Show your Bookmarks (Crtl+Shift+H)" buy just clicking the icon, the main bookmark menu opens. I can move the cursor down the list. But if I try to use the scroll wheel, as soon as the wheel moves, the bookmark menu list closes (disappears).

I like the small size of this particular mouse since this is my travel laptop.

I have tried all the Logitech SetPoint software mouse option with no luck.

Is there any appropriate about:config option that would affect the bookmark menu list?

Thanks

Firefox v78.0.1 and Logitech Setpoint 6.69.123

When I cut and paste text into the chat edit window in the discord website app, the text I am pasting appears twice. This started happening within the last month. I am using Firefox 78.0.1. This does not happen in chromium, for example, nor in pasting info to other applications. I am running the latest Linux Mint OS as well.

After updating from 77 to 78.0.1, I've experienced a large number of tab crashes ("Gah. Your tab just crashed.") across multiple sites. No crash logs are available in about:crashes. I've tried:

• Starting in safe mode
• Refreshing Firefox
• disabling security software (Webroot SecureAnywhere)
• Disabling hardware acceleration
• Making sure latest drivers and Windows updates are installed
• Run Windows system file checker tool (no errors found)

I use Firefox with screen reading software, so it is possible the issue may be accessibility related. I've tested with JAWS and Windows Narrator and experience the tab crashes under both.

OS is Windows 10 Version 1909 (OS Build 18363.900)

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 "Flexible Space" item is useful to separate icons on my Firefox (78.0.1, 64-bit, Windows 10) toolbar, but I don't need it as wide as the default. Is it possible to modify the size, and how would I go about it?

I can't stop autoplaying videos in FF77. I disabled them in the options, and also set

media.autoplay.blocking_policy = 2

and the videos still play automatically after restarting FF.

Hello everyone, I ran into a problem that I can’t get to the site https://1x-rate.com/. I don’t have access to it from my home IP, because I have always used the plugin, but now none of the plugins want to work in my browser. I asked friends to check the site’s performance - everything works fine for them. It is important for me to save cookies in my browser because I would not want to reinstall it, can someone tell me how to fix the situation?

I am a facebook marketplace seller and I use my selling page every single day. After the update on July 3, my selling page is now showing in mobile format instead of PC. I just realized that my home page on facebook has been in mobile view for some time now. I am in the classic view on facebook I have not updated the page to the new style. The mobile view on facebook selling page is absolutely terrible and not user friendly. I have cleared my firefox cache, I have cleared all logins and autofill items. At one time when I right clicked the page and the view page info came up, it said android. now it does not anymore. I have tried everything I could think of to change the page back to PC view. I am not on the m.facebook.com page, either. It seems that all the other pages are normal, this just pertains to facebook.

So up until firefox updated... yesterday? day before? not sure my circadian Rhythm is a total mess at the moment. but ever since that most recent update picture in picture doesn't pop up on netflix anymore?

i can still use it on YouTube and Prime Video, the only other sites i use it on really, but not Netflix?

as you can see, the icon appears fine on youtube, but on the netflix screenshot, it does not.

dead annoying since watching a show with picture in picture while grinding in a windowed game is a poor gamer's second screen.

The new design of Reader View has two problems:

1. Given that this feature is particularly important for those with eyesight problems or other disabilities, it seems like a bad move to have made the buttons smaller.

1. The buttons used to be on the left-hand side of the window, but now they're directly to the left of the page text. This means that the pop-out controls for the Listen button now overlap the text. So if I want to be able to read the text at the same time as listening to the TTS, I have to click a second time on the Listen button to hide the pop-up. Then I have to click on it for a third time if I want to stop the TTS.

Firefox will NOT allow me to open a number of web sites including State Farm and Vanguard. (Currently i have to use Edge to open those sites.) is there a way for Firefox to allow for an "exemption"??? THANKS!

Hi,

 Certain sites saved to Bookmark Menu require two tries to access. First mouse click>nothing. Second try> brings up site. It is not the mouse & I've tried in Safe Mode. This happens every day. Any help appreciated.

Thanks

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
