Firefox Support Forum

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.

Embedded links in Outlook email on Windows 10 will not open automatically when the new email is first opened to be read if Firefox has been selected as the default Browser. This is a new issue !

The message is" if there are problems with how this message is displayed, click HERE to view it in a web browser " and then the Browser used is only Edge!

Restoring disliked Edge to be the default browser corrects the issue but Edge is a known tracking device.

I like to split windows so I can have running YouTube videos on the left half of the screen and browsing the web on the right. If I open another site on the right side of the screen that has multimedia (ESPN, CNN, IMDB), the video freezes on the YouTube window but audio continues to play without issue.

I have done the following troubleshooting steps:

• Hardware acceleration turned off/on
• cleared cookies/cache
• A few About:config fixes

Videos don't have a problem running if I open YouTube with Chrome and continue to use Firefox for surfing.

Hi,

I am a student, who tend to mass download files at once. The annoying part is that after every download, firefox automatically opens up the downloaded file in a new tap. How can I disable automatically open files after download?

Thanks.

Dark Reader works for all sites except for mozilla.org, I think these webpages are over-ridden by the Firefox browser? I saw a couple archived posts recommending global changes for all sites via Firefox -> Settings -> Language and Appearance -> Colors, or to install themes. Neither option would work. I don't want to override all sites to dark globally, that's way to much change, just let Dark Reader change just mozilla.org.

I loaded the postcode lottery website but it's completely blurred. I last checked the same website last month, and it worked fine. I have cleared the cookies from Firefox, but the result is the same. It appears clear for a moment, then blurs. No pop-ups asking to accept cookies. It works fine using Chrome. Any idea why Firefox won't display it properly? It loads the National Lottery website, so it's not about gambling sites I guess.

i had to rebuild my laptop computer and set up firefox on it, set up/turned on sync and the browser does NOT match the broswer srttings on the desktop where the sync comes from. bookmarked weblink icons only show up when a new tab is opened and vanish once a website is opened, icons for bookmarked weblinks on the bookmarks bar are generic wireframe globe-like-icons only, the custom firefox colour setup i struggled to create over the course of several weeks does not appear at all, nor does the dark theme. how then do i get this to -really- syc???

I often see a Shortcut on my New Tab that I have never gone to, which says "sponsored" on it. I do not want these ads. I have looked up the answer: https://support.mozilla.org/en-US/kb/sponsor-privacy?as=u&utm_source=inproduct I can manually delete a sponsored shortcut once, but this does not stop them from coming onto future New Tabs. My problem is, the long-term answer simply does not work. Settings -> Home -> Firefox Home Content simply does not contain a section that says "Sponsored shortcuts" and therefore this solution is not accessable. I am on Version 120 as suggested. What is going wrong? How do I prevent these ads from appearing on the New Tab page?

Hello all. I'd like to restore the backspace button function but the previously workable solution — resetting browser. backspace_action to 0 — is not working for me. Any hints as to why that might be the case?

On FF 120.0.1 and Tab Reloader 0.6.1

I have FF set up with 7 tabs as home page, 6 of the tabs have tab reloader set to reload ever 1 hour. This has worked fine for years, the tab reload for the 6 tabs were saved after restarting FF. I didn't have to go back and tell tab reloader to reload after restarting FF. Maybe once and a while one tab didn't get the reload saved on a restart, usually always the same one.

Now when I restart FF none of the tabs have saved the setting to reload every 1 hour.

This has been going on for the last 2 releases of FF updates and there hasn't been any updates for tab reloader. Does anyone know why this is happening, I haven't changed anything in settings. I did uncheck hardware acceleration to see if that would fix another issue, but tabs weren't reloading after restart prior to that change on hardware accelation.

Whenever I attempt to watch something on any streaming service, I get an error message from the streaming service and a note from Firefox saying "The WidevineCdm plugin has crashed." I have tried to solve this problem a number of ways, but have unable to find a solution.

My best guess is the problem is due to the most recent WidevineCdm update, as in the plugins settings the most recent update for the plugin was on 10/21/23, which is shortly before I first noticed the problem. I did test out various streaming platforms on other computer browsers (Chrome and Microsoft Edge) — they gave the same website errors as I got on Firefox, but those browsers did not indicate the cause or suggest which plugin failed. I additionally tested out desktop apps for some of the streaming platforms; they work fine without any issues, but unfortunately the main streaming platform I use doesn't have a desktop app and only works in browser.

My computer is a Lenovo Yoga 9i, it's running Windows 11, and everything is up-to-date.

The methods I have tried to fix this issue with, to no avail: - submitted crash reports - toggling the "play DRM restricted content" options in Firefox, and toggling whether or not the WidevineCdm was activated, closing the browser between each toggle of options - clearing Firefox's cache - running Firefox in troubleshooting mode to make sure it wasn't a different extension interfering with it - tried running Firefox in compatibility mode - tried to find support from the people who made WidevineCdm, but apparently they don't do end-user support - deleting the WidevineCdm manually from the program files for Firefox and Chrome (since Firefox says the plugin is from Google), and then reinstalling it via the chrome components page. This briefly lead to the message on the plugin page that WidevinceCdm would "begin installing shortly." It seemed frozen like that for a good while, but then I tried clicking the "check for updates" and that message disappeared, and it went back to crashing when I tried using a streaming service. - uninstalling both Chrome and Firefox, restarting the computer, then reinstalling both browsers

As far as I can tell, the plugin comes automatically installed in the browser, and there isn't an alternate plugin for decrypting DRM-restricted content. If there's a way to set the WidevineCdm to a previous version before the update that's crashing it, I haven't found it, but I am no expert in computers or coding, and my guess about it being caused by the recent update could be wrong too.

I'm at my wit's end here, any help fixing this problem is greatly appreciated.

I am getting notifications with the Mozilla logo or sometimes with McAfee logo saying "5 Viruses found, your computer is unstable" and various other warnings. They all also say "via qltuh.titanicooler.top" I have attached a picture.

I have closed the browser, I tried clearing my cache, I have scanned using both AVG, AVAST, F-Secure Online Scanner, and Microsoft Safet Scanner. I am not quite sure what else I should do.

Thank You
