I-Firefox Isithangami Sokwesekwa

I can sign into YouTube ok, and the pictures of the video's are ok, but whatever I try to watch I get a green screen and just the video sound? It started happening yesterday. I am getting fed up with YouTube and the issues it has with Firefox. I'm having to use Microsoft Edge to watch videos. I've done the 3 resets it says on the support page, but still have the issue. Many thanks for getting back to me.

Popups for Smithsonian magazine keep appearing, sometimes 2 at a time, despite having popups blocked. I need them to stop. They are annoying and cover up content of web pages.

As of recently, every time I try to watch someone on Twitch, where the video feed would normally be is the streamer's offline banner image. Chat is working fine, and is active despite the stream not being displayed on my end. If I check the Twitch mobile app the stream displays as normal, so I know they are currently streaming. I tried disabling all of my add-ons and restarting the browser to no avail. I am a noob, so please be patient with me. I have attached images of an example, but this happens with any live channel, not just ones I am following (I do not have any active subscriptions as far as I know).

I am running Firefox v 120.0 (64bit) on Windows 10 Pro version 22H2 OS build 19045.3570 and today Firefox has stopped playing the video track on youtube videos or any video that is embedded in a page. Audio works but the screen just shows a blank field of green. The progress bar will show frames from the video. IF I run Firefox in trouble shooting mode the videos play as normal with video and audio tracks.

I have already refreshed fire fox and uninstalled and reinstalled it but the video track is still a blank field of green in both full screen and small screen modes.

Anyone have any ideas on what configuration setting may be causing this? Thanks in advance, Brocky

I need a fix for my ESPN+ account. I can watch live sports and videos but cannot read ESPN+ articles. Everything works great with Edge and Chrome, so maybe I will have to switch browsers.

New computer, Win 11 and FF 120.0.1 all fresh installed and updated with latest versions. The double line spacing in bookmarks and all other menus is back. There was a fix for ver. 89 with the css file trick, but that DOES NOT WORK with this version. All other options I've run across don't work either. Why do the Mozilla software engineers think it's a good idea to break their flagship application every few years? Rhetorical question, I know.

Does anyone have a user fix that actually works with this FF 120.0.1 version? Something an experienced user can do that is not a programmer. analyst or engineer? I've been using FF since it first came out to challenge Microsoft's IE. Late '90s? I'd like to keep using it but this is too annoying to tolerate.

If anyone can help with step by step instructions, I would be eternally grateful.

Hi, Please advise how to remove, disable, delete, block the new added "Your browser is being managed by your organization." to my Settings page. I'm home user .Also Please know that this is generating "FALSE FINGERPRINT CERTIFICATES" thank you

The puzzle piece icon is not on the toolbar. Neither is it shown in the customize toolbar dialog. I have reset the toolbar to default, rebooted Windows 11 and removed & reinstalled Firefox 120.0.1 (64 bit). Those did not work. How can I restore the puzzle piece icon to the toolbar?

I've been trying to sign in to pinterest, duolingo, etc using the 'sign in with google' option since my account was saved there. Whenever I click it, a sign in window opens up as usual, but it only ever shows a blank screen. No matter how long I wait, nothing shows up. I tried clearing cache, and it still didn't work. It worked before, but recently since the past 2 weeks, it became like this and I don't know how to fix it.

I have some extensions on my account so I'll list them out just in case one of them is the one making this problem: -Search by Image -Firefox Relay -uBlock Origin -DuckDuckGo Privacy Essentials -TWP - Translate Between Pages -Ecosia

(Below is a screenshot showing what I mean by the sign in window being a blank screen.)

Firefox on my mac has recently started displaying strange text in any windows where the browser itself chooses the font. I verified that the font settings are default, and the issue persists. Screenshots attached, any ideas?

Only my mac has this issue, my iPhone, as well as two Windows PCs all on the same account do not present with this.

I had 2 windows open, closed one, lost all of my tabs. Restore didn't work. I tried to restore by renaming session-store-backups folder files. doesn't work. There is a file called upgrade.jsonlz4 from November, maybe that could be used to restore tabs somehow?

I've set custom fonts through Settings > Fonts > Advanced, but the fonts I have specified are not being used on any websites even if I uncheck the box that says "Allow pages to choose their own fonts, instead of your selections above". For example, I've set the default sans serif to Source Sans 3, but websites use Arial regardless of the settings. The only custom font I've gotten to work is Segoe UI (the UI font on Windows); all other just fall back to Arial. The problem persists even if I disable all extensions/add-ons. I'm also experiencing the problem for non-Latin scripts; I've tried to set the default Bengali font to Noto Sans Bengali, but websites are using Vrinda instead.

I'm running Firefox version 120.0 on Windows 11, any help is greatly appreciated!

Twitter not working properly on Firefox (Volume on videos can't be changed, hovering over buttons doesn't do anything and font looks a bit off, could be just Firefox font or something) works on chrome and other browsers.

This is so strange.

My Screenshot Icon in FF 120 is gone. Tried adding it back, but it's not there under More Tools -> Customize Toolbar. Overllayed Firefox with a new install - no change. Disabled/enabled extensions and themes. No go.

Am I the only one? Any ideas?

Thanks. :)

I am using Firefox 120.0.1, and I have difficulty to take screenshot.

I tried to press shortcut key and button in toolbar as shown in the attached image, but they didn't work.

Is there any good way to fix this problem without reinstall firefox app?

I'm getting Access denied Reference #18.6b01cb8.1700662622.22a58314 only on tesco.com since last nights firefox update.

All other sites are funtional (at least no others found yet). I have cleared cache and cookies but still getting the issue.

The site is up and accessible by ms edge.

I have run in troubleshooting mode and taken off any extensions, still no change.

Running windows 10 (latest updates)

Malwarebytes is reporting no issues.

As the title says i have enabled always ask where to save files but when i try to download files it saves them in my Download files most of the times.I didnt have the problem yesterday. Can you please help.

Hey,

I've been having an odd issue with Firefox where tabs where I attempt to access youtube.com will immediately crash. This issue first arose when I attempted to log in to Youtube, and had never occurred before. When I did that login, the tab crashed, and I have been unable to access the website since (100% crash rate).

Basic details: The website does not visually load at all. However, the URL bar icons for the website do briefly appear prior to tab crash. (Autoplay button, etc). The crash is never reported in about:crashes.

I've tried the following tests, unsuccessfully: - Logging out of all Google accounts separately - Disabling all extensions - Transferring all of my data to a new computer - Reinstalling Firefox - Rebooting Firefox in troubleshooting mode

This problem does not occur on my Windows machine but occurred on my previous intel-based Mac and now on my current Apple Silicon Mac.

The only success I have had is in creating an entirely new Firefox profile. However, I would prefer to fix the issue, as I assume that porting all my settings to the new profile would... also probably bring the bug along.

Thanks for reading & any advice is appreciated.
