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.

Majority of the songs do not play and I'm given with a pop-up, "Spotify can't play this right now. If you have the file on your computer you can import it."

I will play a song from a playlist and is given that pop-up, it will continue skipping to the next song until it plays, but only for 9-10 seconds until the song mutes, to specify, the dot (when hovered on the progress bar) will still move, indicating that "it's playing".

Some clarifications: 1. I use Spotify Desktop app (windows), Spotify App (android), and Spotify Webplayer on Chrome and Firefox. Everything works just as fine on all of these, except for Spotify Webplayer on Firefox. 2. Skipping to a later timestamp does not unmute the song. 2. I have Spotify Premium 3. I have no VPN 4. I am running Firefox with an ad blocker 5. I am running Chrome with an ad blocker (same ad blocker in Fifefox) 6. I am running Firefox to the latest version (Firefox 119.0.1 (20231106151204))

What I've done so far: 1. Cleared caches and data. 2. Updated my Windows to the latest update available - Win10 v.22H2 3. Signed-out of Spotify for all my devices, then logging-in first on Spotify Desktop (this automatically redirects to Firefox webplayer) 4. Ran Firefox on "Troubleshoot Mode" 5. Un-checked and re-checked "Play DRM content" setting. 6. Disabled and re-enabled the plug-in "Widevine Content Decryption Module by Google Inc". (this plug-in is last udpated on November 17, 4.10.2710.0

I'm including this link from Spotify's Community page.. where two other users, who commented it is only with Firefox (webplayer), are experiencing the same problem as I am. https://community.spotify.com/t5/Desktop-Windows/Spotify-can-t-play-this-right-now-If-you-have-the-file-on-your/m-p/5679914#M123192

Amazon Prime Videos will not play on Fire Fox. The message says to update Firefox, but my browser is up to date as of today, 10-24-23. Their customer service can provide no answer. This has been an ongoing problem for several months. I have tried their trouble shooting steps of restarting my system, signing out and re-signing in on Amazon and closing and re-opening Firefox. Allow DRM content is checked on my settings. Thanks.

Hi. I'm experiencing a severe lag between Audio & Video on Youtube (video lags audio by more than a second)

This ONLY happens on YT, ONLY on one PC (we have 3) and ONLY using Firefox. I've been through as much of YT as I can find, but nothing changes.

Running FF in safe mode eliminates the problem. I've checked all addons/extensions etc in normal mode, but none are enabled & can't find anything else which makes any difference.

Using Chrome/Edge/IE Explorer all are fine, using a different streaming service (UK TV Play/BBC iPlayer etc), all work fine with FF.

As a last resort, I deleted FF and all associated files, folders, registry entries and caches. Upon re-installing FF the problem returns.

I've tried running without antivirus protection, in case a firewall or somthing was messing with it, bit to no avail.

I'm totally flummoxed, so if anyone can shed some light, it'd be much appreciated. I really don't want to change to another browser as FF has served us well for years.............. but....y'know.

Thanks. Annie

For the past few days, Firefox has been freezing up. By playing around with it, I've found that it's still functioning, but it ceases to update visually. I'm not having the same issues with any other program on my PC, I don't see the icon to update Firefox, and I've restarted my PC a few times along the way.

When this happens, it's not just website contents that freeze, but Firefox's UI as well. Hovering a tab doesn't highlight it. Clicking the hamburger doesn't appear to open the menu. Etc...

If I have a video playing when this happens, I will continue to hear it, but the frame the video is on stays in place.

If I click on another open tab, it will still show me the tab it visually froze on, but if I end Firefox with Windows Task Manager & reopen it, the session saves the tab switch, so it's still taking mouse inputs. I've been able to do similar with keyboard inputs by clicking on the address bar and entering a new URL. I don't see anything as I type it, but after using Task Manager to close and reopen Firefox, the site I entered is there.

I can switch between open Firefox windows when this happens without issue, even on the same monitor, and if I pull up something else in front of Firefox and then switch to Firefox it will still display what was last visible in that Firefox window while the bug is occurring.

I have tried disabling add-ons, and actually found that disabling some of them made it happen *more* frequently, not less. Privacy Badger, Auto Tab Discard, & Ad Nauseum specifically. Switching from Ad Nauseum to AdBlock Plus or uBlock Origin neither increases nor decreases the frequency. My other add-ons, like Duplicate Tabs Closer, haven't had any effects on frequency that I can see. With all of my Add-ons disabled, Task Manager shows double the number of Firefox processes.

I tried to clear my history, but I can only select my last 1 hour of history, as clicking on the dropdown box to select another duration will cause the problem to occur & I can't see the other options in the box to select a longer option. The dropdown to select a topic for this question has the same issue.

These are some actions that risk causing the bug to start, but aren't 100% reproducible, and the list is not exhaustive:

• Trying to click & drag to pull a tab into becoming its own window or to move the tab into another window. (Firefox does not save this movement if it causes the bug, so closing and reopening it will keep the tab in the window it was already in.) This seems to work fine for some sites, but specifically tends to break if it's a YouTube tab.
• Mid-clicking to open a link in a new tab, if done on several links in a row
• Clicking on a UI element, like the hamburger button
• Right clicking on an image and selecting "copy"
• Right clicking within Firefox
• Opening Firefox

I have not seen the bug occur at any time that I was not actively providing some input to the Firefox program.

Every time I open Netflix in Firefox browser, to watch streaming movies, it won't show them but keeps taking me to a page asking me to log in again or pay for a Netflix account. (attached) I already have a Netflix account and can watch streaming movies with no problems on other browsers, but not using Firefox, which is my Default browser.

For context, I accidentally made my root D: folder into the downloads folder and during this time I was still able to download using firefox. But when I finally changed the folder to my default one, firefox stopped being able to download anything larger than 1gb files. I can still download small images but anything larger than that I can't download. Else, it would only just show "Failed" in the downloads bar.

I've tried: 1. Changing the download location

>Also tried reindicating my download location

2. Turned off dangerous downloads 3. Putting an exception to the sites I try download from 4. Clearing the downloads 5. Tried troubleshooting mode 6. Restarting my computer 7. Restarting Firefox

I can't download on firefox but the same files I can download on Chrome.

like the subject says the video on disney plus is very choppy/blurry/not 4k like it should be can u guys look into it? the video is blocky and blurry on firefox but not on chrome for some reason and id like to fix it soon

I am experiencing issues with my ChatGPT subscription while using it on the Firefox browser. Despite having an active subscription with access to ChatGPT-4, the interface only shows an 'Upgrade' option instead of the 'Refer a Friend' feature, which suggests that my subscription isn't being recognized properly. Additionally, whenever I try to send a message in the chat, I receive an error stating, 'Our systems have detected unusual activity from your system. Please try again later.' I haven't encountered these issues on other browsers. Could you please provide assistance or guidance on how to resolve these problems with Firefox?"

I have tried to clear the cache, and relogin, does not work...

I am wondering if this is an issue of Firefox or ChatGPT, any resolution on this?

I have a work and personal profile. On my work profile, when I go to amazon, I see the pricetag icon in the URL bar and it works as expected. However, on my personal profile, it's not showing up at all; no icon, no prompt, it's like it doesn't exist for that profile. I've restarted both profiles, and it still isn't showing up.

I'd prefer to do my shopping on my personal profile, and not my work profile. Any ideas why it's not working on one?

I reinstalled Firefox, now 119.0.1 64bit on our Mac M2 now OS13.6 via download-reinstall in the owner account on our shared Mac. The "Firefox is being updated by another instance" line in About Firefox still has not gone away after closing and restarting Firefox.

Presuming this will disrupt future updates, I seek help.

Background: Last spring, I upgraded from a 2016 Mac on OS10.15 (which still appears on my Mozilla account) to this M2 OS12 now 13.6. I had previously set Firefox to prompt me for updates because they could disrupt my work on the old Mac. It worked fine up to 118 point something. Up to my ears recently in urgent other stuff, I deferred the prompt for 119. Then, frazzled, I just closed several 119 prompts. Today, after helping my wife use her account on the M2, I found in my Dock's active apps area an icon for something like Updater something-or-other. After a while, I swiped it away.

I have a Logitech mouse. I've used it with both Brave and Chrome problem without problems highlighting text. But the highlight function doesn't work properly with the mouse in FF.

I can double click and highlight a paragraph. I can highlight a single word with no problem. But when I try to highlight a series of words or a full sentence, I can't. Either it highlights but when I try to Copy the highlight disappears. Or when I drag the mouse to highlight it won't highlight at all.

Since the issue only occurs in Firefox and not other browsers, there has to be something in Firefox that's causing this; or some conflict causing highlighting not to work.

I'd be grateful for any ideas how to fix this. It's driving me crazy.

On both my old laptop and a new one (so a new installation of Firefox), I'm unable to load Frontier Airlines' website (www.flyfrontier.com) and get a time-out message:

The connection has timed out

The server at flyfrontier.com is taking too long to respond.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

This happens even with all of my extensions disabled, with enhanced tracking protection turned off for that site and with HTTPS-only mode and DNS over HTTPS disabled. It also happens when using Firefox in safe mode. Safari loads the same website very quickly and with no problems. Does anyone know what might be going wrong? Thanks.

When I visit an http site and specify a non-standard port, it automatically changes to https, which is not a site redirect but something Firefox changes. This site already has an https service, and the http service will redirect to https. I reproduced the same situation in chrome. Accessing the http service with a non-standard interface was normal. After accessing the https service once, the service with the non-standard port was also changed to https. Clearing the data will restore it. Is this cached? My HTTPS-Only Mode is turned off, and set an exception for this site. thx.

Since Firefox update 19.0,1 flightradar website freezes when I click on an aircraft...

Using brave browser no problems.

windows 10 laptop with windows security all updated.

I'm a Reddit user and until today I used to login just fine. Now I get the error message "Incorrect username or password" when I try to login in Mozilla Firefox (version 119.0.1 (64-bit)). If I use Google Chrome or Microsoft Edge I log in with no problem.

Firefox remebers my data for previously filled in forms - thats fine. BUtr how can I get it to know my basic data (name, email, phone number etc) for forms / sites I havent previously visited?

Lately, far too many websites I try to open, simply won't! Sometimes it's via links from my home page, sometimes it's links within various websites, like a newspaper, or social media, just whatever, no rhyme nor reason, nor consistency. Even when I manually input the url, nothing happens, the browser just sits there, nothing happens. I've restarted, I've refreshed websites, clicked on "open in new tab/window", nothing gets it to work.

As described in this thread (https://support.mozilla.org/en-US/questions/1431159#answer-1618832), I had a problem accessing one particular domain after doing everything I could find to fix it. Setting DNS to Increased Protection fixed it. It's partly just curiosity but also concern that I'm asking if there is an issue that should be addressed.

The basic scenario: could not access one particular domain only in FF on one computer. No problems with FF on other devices and no problem with other browsers on the computer in question. Configuring DNS settings to Increased Protection is the only thing that allowed me to access that site (which happens to be the org I work for). So the setting is only necessary on this device and only for that domain.

What's the explanation or solution for ensuring I don't have other DNS issues, or something else, that will be a problem later?
