YouTube is blocking playback on Firefox due to my use of an ad blocker. However, playback is not blocked in the same circumstances when I use Chrome. Are they trying to stop me from using an ad blocker or overturn my browser choice by forcing me to move from Firefox to Chrome for playback with an ad blocker enabled?

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.

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

Hello,

I'm seeking help because sound is not working on Firefox. All other software are able to produce sound on every speaker and headphones I have. The speaker logo does not appear in tabs were videos or music is playing and firefox doesn't show up in EarTrumpet. It does show in the volume mixer but no bar appears to show it is displaying sound while media is playing.

I'm running : Firefox version 119.0 64 bits Windows 10 64 bits version 22h2, OS build 19045.3570

I've tried :

1. Restarting Firefox
2. Muting/Unmuting Firefox in the volume mixer, in firefox tabs too
3. Downgrading to version 118.02 32 bits
4. Uninstalling all my audio drivers followed by a restart (they got re installed but no change for Firefox)
5. Restarting Firefox with all addons disabled

I'm running out of solutions.

Kind regards

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!

I have used Firefox since forever, was a Netscape user in the past

But for about 3 months Firefox simply is no good anymore\

It is more and more sites I can not access with Firefox and have to use Edge instead.

Last example, just now

https://www.cibc.com/en/journeys/new-to-canada.html

See screens attached

This is just one example, many other sites simply do not open, or open properly, in Firefox

WHAT IS HAPPENING?

Thank you

How can I turn off the threading of my emails? Its driving me crazy as when an email comes in after a short time it disappears into the threads and then I have to open each thread to find out who sent the email. At one stage there were 6 emails noted near the inbox but no new unthreaded message, all went to respective threads. Very time wasting.

I am not sure when exactly problem started but for few months I have problem with automatic update of firefox. It properly detects update and downloads it but when I click to restart browser and apply update (this should close browser and display update install bar) nothing happens - browser simply closes. When I launch it again and go into "about firefox" again I see spinning circle next to "installing update". Of course this update never installs. When I close it for 2nd time and go into "about firefox" it goes back to "update ready to install, click to restart" - and again, when I click it browser simply closes without restarting and installing update. I tried removing my profile, using safe mode, disabling antivirus. Issue seems to be related to firefox itself. I also tried removing mozilla maintenance service but it did not help. Does anyone have any idea what could be causing this? For now only way for me to update firefox is manually download full installer from website and then it installs latest version without any problems - until next month comes and I have to update it again.

My Kaiser website kp.org can't come up...the following error message:

"The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies."

Hello, today firefox has been appearing as a blank icon on my taskbar. I have tried solutions suggested in older posts but it did not help unfortunately. if i try to

1- right click unpin from taskbar the icon shows once more. 2- right click, the icon disappears/becomes blank. 3- click pin to taskbar, the icon remains blank.

attached is the image showing the steps i described above

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 have Startparge set as my default search engine. I used to type directly into the address bar (see first image).

Press Enter, and the Startpage results page for this search phrase would show up. Somehow, this has now changed. I press Enter, but the result is just the Startpage home page, with a blank search box (see second image). So I then have to type the same phrase in again in Startpage's own box. This just trips me up.

The crazy thing is that this only happens sometimes - but more often than not. I haven't seen it work right for weeks: I just did it now to make screenshots, and it worked wrong. I just did it again and it worked as expected: pressing Enter took me to Startpage's results.

Any clues how to change settings to fix this?

I don't like the new printer dialog box Firefox came up with. It is too basic. 9 times out of 10 I have to click over to the System Dialog Box. Is there any way I can permanently switch to System Dialog Box? I am running Windows 11/64

Cannot get out of the terrible firefox print dialog. Literally no one wants this print dialog, it is a waste of time, and does not support all the printer options. I do not want to have to click "print using the system dialog" every time. Please restore the print.tab_modal.enabled = false functionality immediately. Or better yet get rid of your stupid print dialog.

thanks

Hello,

the newest update to version 97.0 was run automatically. Afterwards the new print preview appears although I have it disabeled in about:config (print.tab_modal.enabled --> false). I cannot get rid of it. It is very annoying as I cannot print my labels with that menu and always have to click once more to do so. Does anyone has a fix for this?

Thanks in advance,

Thomas

OK I have been trying to go 100% Firefox for just a few months but with privacy and security as primary directive. It would be wonderful to just be in ine well moderated browser ecosystem and actually being able to have my preferences, interest and personal information centralized with eventual goal of digitally divorcing tech companies from my personal data. I still have to use a lot of different devies with varying OS and it literally took me two years to help Apple fix an AppleId problem. Now that I have that sorted out I have been hoping to move away from gmail entirely and eventually have my own mailserver but using icloud now for macs and pcs.

At a minimum it seems like even after forced manual I have not properly sync an imac with windows 10 PC. So to keep it simple I stay there but this morning when I typed into Firefox on my iMac its was google search not Duckduckgo. Not only have I synced it in firefox but icloud should be redudant and I had removed google from list of potential search engines. There seems to be some way for a hostile takeover of these settings and google connstant agressive intrusions asking for data is not just wrong or annoying its simply impossible to not have facebook or google track me beyond california digital privacy standards. The worst offender may be youtube. I want to fix the browser and sync my stuff. But I am also looking for extensions that will help me do that better.

I am pretty thorough and now just want to learn more and would like to believe one can have a semblance of privacy but it seems like it will be an adversarial experience when the companies that do can rollback privacy with clever tv ads. The 'providers' clearly do not give hoot about rules, preferences and laws designed to protect people's rights.. That is what is particulary frustrating. It is not a fair fight but a good one. I guess what I am wondering is if there are specific modules you could add to detect maybewhen an event like change in search engine occurs and whether logs may exist as to how or why the change was made. Even if it was an accidental quick through a popup in chromium or edge where I was always being cued to come back to Chrome. Logging out doesnt always seem to work so i tried syncing with and chrome with more or less same results. Very little actual control or at least a tendency to revert back to the data miners preferences over mine. I want to help stop that.

I was quite unhappy with the new Firefox Proton design, so I made a CSS file and copied the following code from a website. However, I don't know what to do to (1) slightly reduce the tab height, (2) get back tab borders for inactive tabs and (3) remove the small gaps between tabs. How exactly do I have to change the following code to do so (ideally, for convenience, please just complete the code accordingly)? Thanks in advance for any support!
