Firefox Support Forum

When playing any youtube video in full screen, all I get is a black screen. Issue does not appear in private mode, firefox developer build or chrome. Other sites ex. go pro media plays videos in full screen without any problems

Hi!

I can't scroll with the mouse wheel in Firefox. It works fine in other browsers and programs.

If I switch to Safe Mode, the scrolling wheel works. But if I switch back to normal mode, the wheel does not work again.

I tried to switch off and switch on "Use autoscrolling" and "Use smooth scrolling" settings, but it didn't help.

Unfortunately, "Refresh Firefox…" and reinstalling browser completely did not help.

I am at a loss, please help.

the latest firefox update has disabled scrolling/ i have tried changing the settings in firefox and no changes make any difference. scrolling works on other apps perfectly fine.

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

Maybe this is obvious and I just don't know the proper terms to find a solution, but I've recently lost the little loading icon that spins in the left hand corner of a tab when you load a site (see gif). No idea what happened to it, but I've tried refreshing and reinstalling to no avail. Yesterday I reinstalled Windows 10 on my machine (not because of this) and it worked correctly until I booted up this morning and it's switched back to that weird icon. Any ideas how I might fix it? Could something like a windows update have messed it up? I miss that little spinney icon more than I would have expected.

After a recent reinstall Firefox seems to have a problem. This seems to be only Firefox specific and I can't find a working solution online after googling.

Youtube videos work, although they do give errors sometimes. A refresh always fixes those. However Twitch/Youtube live streams do not, and display a generic error message. When trying other browsers the live streams work fine.

And old Bugzilla post (https://bugzilla.mozilla.org/show_bug.cgi?id=1467495) describes what I believe to be a possible reason for the problem, however following the solutions in that thread have not yet lead to a solution.

Any further insight or solutions would be appreciated.

Hello,

When Firefox updates, a new tab is openned upon the next start, with the new version content or patchnote. I would like to avoid this informative tab.

Is there a way to deactivate it?

Thank you in advance.

This morning, upon opening Firefox, I noticed that I could not scroll through any pages or windows. I turned off scroll lock (or so I thought), and it began scrolling. But then, in all of my other windows, scroll lock was activated. So, I hit my scroll lock button again, and now all other windows will scroll except for Firefox. Is there a setting I need to change?

It appears as if scroll lock is reversed on Firefox vs. all other apps on my computer.

All of my extensions just got moved into a single new extension button. I understand this feature was just added to 109 but is quite terrible.

I can no longer see my extensions on the toolbar. I now have to do even more clicks to access certain options or settings. Which is dumb as it now takes longer to get where you need to go.

This is a terribly added feature. Not sure how this passed. The quality of life is not improved in any shape or form with this. Only makes things worse.

For example. I have norton safe web and search. I now have to click on the extension button to see if a page is safe or now have to do multiple clicks to access that extension.

This new feature is terrible and I really hope it is reverted.

I'm getting popup notifications from customer-service25.higherincomejobs.com and jobsflag.com, even though I've gone to those sites and unsubscribed. Is this a virus? Is there a way to get the popups to stop?

I'm attaching a screenshot showing one of the notifications in the lower left corner of my screen.

Any help would be appreciated.

If I set my tab title bar height to 30px in my userChrome.css the tab titles are no longer centered (top to bottom) on the tab bar. The top padding on the tab titles needs to be reduced by at least 3px and I would be grateful for a code snippet that does so.

OS version: Ubuntu 22.04.1 LTS (jammy), 64-bit (amd64, x86_64). Firefox version: 110.0 (64-bit) (NOTE: the issue was noticed with version 109.0, too)

Firefox package was installed on Ubuntu through 'APT', using the Mozilla Team repository (https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/). It caught my attention that an excessive amount of Firefox related 'DENIED' AppArmor log messages is generated during the browser activity.

According to messages, Firefox is occasionally denied read access to '/sys/devices/' area and read/write access to 'oom_score_adj' target in '/proc/'. Could somebody clarify why would that access be required for regular browser operations? I'm a bit puzzled as I haven't noticed anything similar with the older Ubuntu and Firefox versions. A complete suppression of those messages is also an option as long as there's no negative impact on application's performance.

I already posted this question to Ubuntu forum but seems like nobody there could provide an explanation. I'd appreciate any input or hint.

Following is the sample of referred log messages:

Hi. I want to sync with my work pc (it used to work just fine but when I synced to a newer third pc- successfully- it just stopped). When i try to sign in on the work pc it asks me for the primary password which it then FAILS to recognise to allow me to proceed! What's going on? I can't even log onto sites with saved passwords anymore. Any help appreciated.

Two updates ago, I had an issue where if I used any Google web products, I had weird network problems that just didn't go away (4000ms ping spikes every 5 packets). I noticed it was only when I was using Firefox, so i tried disabling add-ons and extensions, it still happened. I opened it in safe mode, it still happened. I tried using Chrome and Edge, both did not cause issues.

I reset my Firefox completely (There was some custom CSS to put tabs on bottom, where they belong) and it was perfectly fine! No issues! Everything was great for a few days!

Then you guys updated things again... and it was back... so I reset my Firefox again, and even straight out of the box, its still causing the issue, but now only when using google products, with or without add-ons, there is no custom CSS anymore either.

I do not know why its an issue, but it is, and it is ONLY with Firefox, and I really do not want to switch to Chrome or Edge... It also persists after Google is closed, until I restart Firefox.

I am unsure of specifically why this is happening now, but it is a MAJOR problem for me

Recently I've noticed that some sections in Google search results pages show black text on dark backgrounds when running dark mode.

It doesn't happen in private windows or in troubleshooting mode, so I suspect it's some obscure custom setting that's causing the issue. It also doesn't happen in other browsers.

I've tried switching themes and changing the colour override settings but can't find the setting causing the issue. I've also tried clearing the browser cache and cookies but no dice there either.

Hoping to avoid a refresh just to fix this.

Help? I rebooted my machine and lost all my open tabs. any attempt to re-acquire them shows just the ones I have open now. It doesn't show any of the ones that were lost. Thanks Monica

Hello. I was reading Quora.com web site on my notebook in Firefox (110.0.1 64-bit) normally, then I got power outage. When electricity returned and I tried to open it again, browser didn't open it and I gave me message:

Secure Connection Failed

An error occurred during a connection to www.quora.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

I've tried to get support from Quora.com how message said, but they told me "this error does not originate from our website". And gave me some suggestions - "The easiest way to fix this secure connection error is to reset the Firefox settings." I've performed "Refresh Firefox", but problem persists. I don't use VPN. Can anyone please help me with this problem?

1) When I played a video on Youtube with Firefox via my computer speakers, they worked flawlessly. 2) Then I plugged in my headphones via the headphones jack, there is no sound. 3) I went to Windows settings and checked the volume mixer and tested the sound, the headphones worked. 4) I opened Edge and played a video on Youtube, the headphones work flawlessly. 5) I played a video through my media player, the headphones work flawlessly.

So my conclusion is that it is Firefox that is broken.

I closed Firefox and restarted it and tried steps 1 to 5 above, still got the same results. Firefox did not play any sound over the headphones while all the others worked flawlessly.

I restarted my computer and tried the steps again and still got the same results.

I also deleted Cookies and Site data from Firefox settings and still no luck.

Any suggestions?
