Firefox Support Forum

tried searching for this but unfortunately i didn't find any relevant posts

trying to set the sidebar width using the 'userChrome.css' file

the css file path is;

C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles\bjf0cg2g.default-release\chrome\

userChrome.css

the css is;

1. sidebar { min-width:34px !important; max-width:34x !important; }

appreciate any feedback because there seems to be an issue with the above

I go to youtube, open a video and the audio plays just fine, except there is no visual. The video says its playing and I can hear it normally but I can't see anything. Subtitles show up, but the place where the video is supposed to be is just blank, the same as the background of the page. Weirdly if I click the settings button on youtube, the one next to the sign in or account button, the video will display as long as that menu is up. If I close the menu the video goes away.

I have refreshed firefox, deleted and reinstalled firefox, removed all my extensions, turned hardware acceleration off (and then back on when it didn't work) as was recommended in a similar post a few years ago, and restarted my computer. Youtube still won't show me a video. It works fine on chrome, just not firefox.

I uploaded a screenshot of an ad, which doesn't play but shows the outline of the video player, a screenshot of a normal video where the area the video should be in is just more indistinct background, a screenshot of the video appearing normally when I have the settings menu open, and a screenshot of the captions loading properly over an empty void.

Edit: I installed the Enhancer for Youtube extension? Which I haven't ever installed beofre? And now Youtube works? Why

The YouTube videos load in troubleshoot mode, so I reopened Firefox and disabled all extensions. That did not help, so I uninstall all extensions. That does not work either. Other browsers work, but Firefox does not.

I bought a new laptop. I installed ZoneAlarm and Virus Protection for Windows 11 as I thought Maybe Wolf and Windows Defender might be the problem. I did everything suggested by Mozilla to get it to let me log on. To no avail.

I did everything. I still cannot get access to https://www.chewy.com - despite my logging in many many times. Please tell me how to fix this. This is STUPID!

This is the error message I keep getting: Access Denied You don't have permission to access "http://www.chewy.com/app/login" on this server.

Fresh install of Kodachi Linux 8.27, added Firefox straight away. New version is supposed to Sync automatically I guess, but it doesn't. I'm logged in to my Firefox account, I got all my bookmarks and synced tabs, but no extensions. This worked fine changing OS's in the past, including moving to Kodachi, Ubuntu, Kali, or Debian, or different versions of Windows. Suddenly Firefox should Sync itself, and it doesn't. How do I get all my extensions back? I had an easy 50 or 60 extensions, and there is no possible way I'm going to reinstall 50 different addons, assuming I could possibly remember what they all were...

Any help (WITHOUT reinstalling every single one)?

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.

Hello, Firefox always downloads a pdf files from e-mail attachments, whether I open it in a browser or with acrobat reader. So, if I open the same file every time it goes to download folder with multiple clones, like example file-1, example file-2 etc. I've used every combination of options, but the result is always the same. I've refreshed Firefox, but nothing changed.

Please help me with this case.

I am having a problem with the Audio and Closed Caption The CC leads the Audio by 40 seconds to a minute. Very frustrating... I seem to only have this problem with HULU and Prime Video. All other streaming platforms work great. I am using Windows 7 64 bit

Any help would be appreciated

Thanks,

'Still having scrolling issues on facebook, where scrolling will jump forward, has this been fixed yet or what's happening? this has happened ever since i installed Firefox, on a fresh install or windows 11 Pro, it's very annoying.'

Norton sign in screen loops with Firefox, works fine with Chrome and Edge. Norton support level 2 has tried for may hours to fix but they have suggested contacting Firefox support as it is a cookie and site certificate issue with Firefox.

Dear, Sir/Madam The website is blank. https://schoenhalde.de/tierkrematorium-balingen/ The website symbol in the top left corner shows that contact has been made even though the page is now blank. Anyone with knowledge of the cause of Firefox's inability to load the website?

After the recent update, the display of my gmail is now so wide in the display window, I have to scroll to the side & back & forth etc. to view the contents of the email on that page. It is too wide to display properly. This is an issue I had with Google, which was why I was using Firefox. Now you are as annoying as they are. I can't just make the whole thing smaller & hope it fits, as I have vision problems & cannot read smaller print if I do that. Can't I just go back to the previous version? I don't know how to do a screen shot of my email inbox page to show you.

I'm having a problem using my bank website with Firefox - I get a message when I move from one page to another, and that message closes the bank website - Here is the message: "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." It is very important to me to be able to view my accounts and investments daily - please help me solve this!

Hey,

My name is Alex. I'm currently using Doxy.me for telehealth purposes. The past couple of appointments I've had have had issues with microphone access. Whenever I connect to the site, I get prompted to request microphone access from Firefox, but when I press the button the browser doesn't give the permission prompt. I've tried refreshing the site/browser, checking permissions on the address bar and in privacy & security settings, but there's nothing there, and I can't manually give permission to the site.

The only change I've had is that I've recently built a new PC with Windows 11, I'm not sure if there's a compatibility issue and I can't find anything about it. I've considered using another browser but I don't like the alternatives and would really like to just use my default. Any tips?

New version produces "Access Denied" when logging into Chewy.com Please fix this. I tried to add an image, but, like last time, doing so froze the page and I couldn't get back here. Had to start over. Can I revert to the earlier version of Firefox that worked? If so, how?

I have lost my personal bookmarks list on the Mozilla Firefox Home Page. I now have numerous bookmarks, some which were in my personal list and some that I may have used in the past, but deleted them. Others are from an unknown source. Maybe a Firefox generated list. They aren't all familiar. Can Someone help me find my personal list that existed before the last update and restore that list.

sign in to email and box appears saying 'Stay signed in so you don't have to sign again' - 3 boxes 'YES" "NO" "DON'T SHOW THIS AGAIN" tick any box and no change next time

The last day or two, I notice that once I have multiple tabs open in firefox, I cannot move/drag them around anymore in the tab bar, changing their order.

To date, I have restarted windows, restarted firefox, made sure both Windows AND Firefox are fully up to date (On a PC), and I have even tried starting FireFox in safe mode- I still cannot drag tabs.
