Firefox Community Forum

For about the last month, if I click on a link in an email or on a website that should connect to another website, there's a long delay in reaching that second site. This did not happen before. The delays are intolerable and do not occur on Chrome, for example. I prefer to use Firefox, but I feel I have no choice but to use Chrome instead. Can my issue with Firefox be fixed? Thank you for considering this issue.

I'm not sure what this feature is called in Firefox lingo...

On my Mac, Firefox will remember which windows belong on which virtual desktops, and so open up with them on the correct (well, not exactly, but sorta) virtual desktops after a restart of the app.

On my new Windows 10 installation, though, Firefox has learned that a specific window was moved to virtual desktop 2, and now INSISTS that that window should always open on the desktop after a restart, regardless of on which desktop that window was actually placed when Firefox was shut down.

Is there a quick fix for this issue, or at least some way to disable this feature?

Thanks :)

Dear Firefox Support,

I recently installed a fresh copy of Windows 11 and then installed the latest version of the Firefox browser. However, when I try to sign in to my Firefox account, it does not sync any of my data. My bookmarks, passwords, browsing history, and other synced items are not appearing.

I have tried clicking the "Sync Now" button, but nothing happens. I would appreciate your assistance in resolving this issue so I can recover my data.

Thank you for your support.

Best regards,

Hello, I am running win 7. Yes and Old computer. When the system is running slow I do a task manager to see what might be causing it.

I have noticed multiple Firefox processes running with 0 CPU usage. What are all those for and do I need them? Can I disable them?

On a separate issue I am getting this rendering error. This may be a Microsoft question, but I thought I'd ask. Error in rendering player Error Code: 400-404 Session Id: k6x4392p (Pls: 35a725dd-3aac-4813-8431-159ebc196c01)

Lastly I did contact support about uninstalling two Firefox programs. I deleted the one you said.

Thanks again for all the help, Irv

Hello,

I apologize if the topic is incorrect, but I didn't know which applied to my situation the best.

Starting on Monday of this week (4/28/2025), YouTube no longer loads properly on Firefox for me. The entire page is covered in video slots with no videos and if I try using a link to a specific video, it will take me to the page, however the video will not load or play, additionally any other elements such as comments or suggested videos will not load. I am using the latest version of Firefox Developer Edition.

I have tried all of the following:

• disabling all of my add-ons
• clearing cache, cookies, and history
• uninstalling and reinstalling Firefox
• logging in and out of YouTube
• Reaching out to YouTube (they told me to just use Chrome)

I have asked my friend who also uses Firefox and YouTube works fine for him, so I'm not sure exactly what is making it not work.

Thank you for your time!

I can not get Youtube to load on desktop Firefox. It works fine on the mobile website, app, and Chrome. I've tried clearing cookies and site data, removing extensions, resetting Firefox, and disabling hardware acceleration, and so far nothing has worked. Has this been happening to anyone else ?

Whenever I get on YouTube the website will not completely load, If I restart Firefox and access the website it then loads completely. However when I click on any video it does the same thing as the included picture, however I can play the video, but I cannot click on anything. This only happens on Firefox, any other browser and I have no issue. I have also disabled my plugins and it does the same thing. I have tried multiple different suggestions from your help page and other solutions on the internet. If I could have some insight would be extremely welcomed, thank you and have a wonderful week.

Hello, I'm a blind, screen reader user. I've used FireFox and Thunderbird for years. In the last month-ish something has changed in the Update Dialog for both apps, that asks if you want to allow the app to make changes to your hard drive. With Jaws and NVDA screen readers, this dialog has normally spoken, so I can Tab to the Yes button, press Enter, the update happens and all is well. Suddenly, this dialog doesn't speak... not a word. Don't know where I am at all. I've tried pressing Alt-Y, which is a Windows accessibility standard for pressing a Yes button, but that hasn't worked in the past, and doesn't work now. I am blessed with a sighted husband. When this dialog has come up in FireFox and Thunderbird the last month, he has kindly bailed me out and clicked Yes. But this is a nightmare accessibility problem. Using only a screen reader there is no way out of this. Escape doesn't get rid of the dialog and just not update. The dialog sits on the screen, not speaking until you take some action. In fact, the first time this happened I couldn't figure out what was going on, but tried to handle it myself. Nothing talked, so in the middle of things, I used the power button to shut down. Well... we think I shut down in the middle of the app attempting to update. So my laptop came up with an error on the screen, and we actually had to use my husband's computer to get into my Microsoft account and dig up a huge numeric code that would allow my laptop to boot. It was bad and took a long time, and my husband is a saint. So... something changed about a month ago in the Update Dialogs for both FireFox and Thunderbird, that causes them to no longer be readable by screen readers. There is not a keyboard way to just press Yes. There's not actually a way to know for sure that the reason the computer won't talk is because this Update Dialog is sitting on the screen. The developers need to know this has happened and fix it. I don't know any other way to reach them. Thanks!

Youtube is nonfunctional on firefox as of April 29 2025. It was all working fine last night, then I woke up to no youtube. It loads the website as a blank screen. Videos can be accessed by going directly to their URL, but no recommendeds load in, no comments section, even the title and channel information is unavailable. I would say none of the buttons work, but there are no buttons to test. It works fine in Chrome still. I know it's not my extensions because I tried removing them all, and it didn't fix it. I know it's not my cache/cookies, because I cleared that too and it didn't fix it. I know it's not on Youtube's end, because it works fine in Chrome. I know it's not an update issue, because I updated my browser and it didn't fix it. Please. I want to be able to use youtube in firefox. Please help me fix this thing. I have attached photos, but I suspect they'll be more demonstrative of the problem than useful for troubleshooting.

When I opened Firefox all my webpages that I visited where there. Now it is just a blank screen and I have to go to webpages manually, there is no way to add them to my start screen. it just stays blank and search bar stays blue.

Hello people,

Please some help around the following issue, since a few days, Firefox will not play mp4 files directly in the browser. What it does when clicking to open an mp4 from the file server, it saves the file first and then opens a window to play it. Or it directly provides the save dialog window instead of playing it in the browser window directly.

Any ideas, appreciated. I have a lot of files to assess for my students, and this browser behavior makes it very tedious.

Greetings.

Good morning. Please I would like your help regarding the following problem that I have been facing suddenly for a few days. Any file I download via email or anything else has UTF-8 stuck in front of its name. Why is this happening all of a sudden? Thank you in advance..

everything as mentioned in this reddit issue and its supported links https://www.reddit.com/r/firefox/comments/1ab87im/firefox_changing_tabs_itself/

for the copying issue https://www.reddit.com/r/firefox/comments/126rtip/copyingcutting_text_switches_to_another_tab/ "" When I press Ctrl+C, Ctrl+X, or copy/cut by right-clicking, Firefox sometimes switches to another tab. This happens sporadically, and seems to resolve itself without restarting the browser or even closing any tabs.

This happens on multiple sites, from search engines to Google Docs to Reddit: any time I try to copy text I get switched to a random tab. This has happened to me 5 times as of now, some of those occurring after a reboot.
