Firefox Support Forum

using firefox version 109 and my internet down load manager no longer works, it works in other browsers but not since updating firefox. not sure if i was successful in posting this request prior to this one so will give it another try. thanks

Screen goes black when some videos play - audio continues, but screen is black. I am sire this is a Firefox problem - I have successfully watched videos using BING browser - same videos go black on Firefox. I have refreshed Firefox, cleared cache, restarted Firefox - cleaned cookies. Turned accelerator off then back on - because nothing changed. Does not do this with all videos, just some - some You Tube videos play, others do not. I have Windows 10 and McAfee Live Safe - all programs are current and up to dated.

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

hello,

i've facing this issue for weeks. i've completely abandoned windows server 2019 as daily os and installed windows 10 with latest patches. installed firefox and firefox developer as usual and did my same settings for years. but videos can't be played on reddit, twitter and linkedin. i tried to refresh browser, disabled addons (only ublock and enhancer for youtube is installed) to be sure. but still got nothing. in my laptop with same addons and same privacy & security settings could play videos.

Two days ago, my firefox browser started not restoring the previous sessions. I changed nothing in the configuration and I don't remember I had a crash. The option "Restore Previous Session" does not appear in the "3-bar menu > history" and it appears grayed in the History Firefox main menu.

What I've already tried or verified following the instructions of mozilla forum: 1) Settings > general > “Open previous windows and tabs” is checked as it always have been; I unchecked and and rechecked but nothing changed; 2) Settings > Privacy & Security > “remember history” is selected. Also tried to Settings > Privacy & Security > "Use custom settings for history" with "Always use Private Browsing mode" not checked. No success 3) I also deleted sessionstore-backups folder under my profile. The new created folder, even after closing some new sessions, has only the "recovery.jsonlz4" and "recovery.baklz4" files. There is no "previous.jsonlz4" inside which seems weird. 4) through about:config I checked that browser.sessionstore.resume_from_crash was true. In fact, I have Firefox in a second computer with no sessions restoring problem. I compared all browser.sessionstore.xxxx variables and the values are the same.

I still have the problem and do not know what to try next. Reset Firefox?

I've tried everything to fix poor picture quality when streaming "third party" videos, e.g., YouTube. Colors are washed out; weird contrast; everything looks like it's coming through a haze. Streams from Netflix, Amazon look normal. And sorry, guys, the same third party streams from YouTube et al. look totally normal in the MS Outlook browser. Have tried all kinds of settings and rebooted as well. No change.

Please advise. This problem appears to be unique to Firefox.

'Screenshot' no longer works. I've used it for years, but this week it doesn't work. I am a woodworker, painter, gardener, handyman, not a computer tech. I want 'screenshot to work like it used to.

After using the browser and closing it, Firefox continues to run in the background and hangs in the task manager, despite the fact that the browser is not running. We have to manually terminate processes. Strange behavior!

my scroll wheel stopped working on firefox, so i launched in safe mode and my scroll wheel was perfectly fine so i disabled all of my addons but it still doesn't work

I've recently switched back to Firefox from Edge and have run into a frustrating issue.

When I try to print documents from Firefox, the "Color Mode" in the print settings is grayed out so I can't select B&W.

This same problem exists both on my MacOS laptop + my Windows 11 desktop. Additionally, they are connected to different printers on different networks. It also occurs whether I'm trying to print a PDF or anything else in Firefox.

Based on this, it appears Firefox is the culprit here.

Any ideas on how to fix this?

Firefox Version: 108.0

Hello, I was using my headphones for watching YouTube on Firefox but then I unplugged them and the audio has stopped playing. I thought the issue was with the volume of my speakers, but the audio worked on any other app. So I plugged my headphones again and I could hear the audio from them. Anything I can do for fixing this (I even restarted the PC but the audio only plays with headphones)?

Regards, Tommaso

I can connect bluetooth devices to my SurfaceGo and successfully direct audio output to them using Chrome, Edge, or internal sound files. But in Firefox the audio only goes thru the internal speaker no matter which audio output device I select. Is there some setting I need to fix so that Firefox will speak to bluetooth devices?

First time ever. Tested other browsers, sound works fine. Changed no settings when it suddenly went silent. Refreshed. Uninstalled/reinstalled. Nada/nothing. So to not feel as if I've lost my hearing, I won't be using Firefox until there's a fix on their end, already tried everything suggested in troubleshooting and refreshed. It's just not playing well with Win11.

FF 113.0.2 Win 7 64 Bit

When I read a pdf online it gets downloaded even though FF is set to always ask. When it asks I choose open with FF or open with Adobe Reader . Both downloads the file to my download folder. It doesn't ask what foder to download to even though I have FF set to ask where to download to in settings/general

I tried setting browser.download.improvements_to_download_panel to false as here https://support.mozilla.org/en-US/questions/1370494 but it didn't help

I have a 2020 Mac Mini with Ventura 13.2.1 on it. I have four virtual desktops which are part of the OS. I place various apps on the others like stocks and weather etc. to diminish clutter on screen. Firefox shows up on all 4 of them. I want it on only one desktop. Safari works on only one and doesn't show in the other 3 desktops. I have searched the net but haven't found anything that speaks to this in particular. Thanks for any help with this and I hope it's just a simple setting. Regards, Jim Stephens

Last week, mid-day one day, videos on YouTube suddenly all had a warm cast --yellowish for color, cream/beige for B&W. I have researched the issue as I can. It is not my Windows night light; my drivers and PC are apparently all updated; everything is working fine. I checked to see if the same happened with Vimeo videos and it did. I'm running W10.

   Interestingly, the pop-up thumbnails one gets when hovering over the timeline as not affected; they look fine.
   One post by someone else was answered that it was a GPU driver issue; another said it's only with HD videos.
   I'm a B&W photographer and would really like to get back to normal again. 
   Any ideas?

I have noticed in the last few days that Firefox is keeping my Mac from sleeping. This seems to have started around the time of updating Firefox to version 113.0.2 which happened 4 days ago. Any thoughts on how to debug this?

console.log(new Date().toJSON()); console.log(new Date().toISOString());

// Actual output: // 2023-05-27T04:21:13.004Z // 2023-05-27T06:21:13.005Z

// Expected output: // 2023-05-27T06:21:13.004Z // 2023-05-27T06:21:13.005Z

This happens only on Firefox and Firefox Developer Edition on one of my PCs and not the other. Firefox is version 113.0.2 (64-bit) and DE is 114.0b9 (64-bit)

Anyone experienced this before?
