Firefox Support Forum

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.

A folder in profile/default/storage with the name 'moz-extension+++d215ed11-a9b2-4927-bd1f-9755184bbe53' is using up 800MB of data on my install and is continuously adding more data.

The above string (ending 'bbe53') does not match with any extension on the about:support troubleshooting info page.

How do I find out which extension is storage data in this folder?

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

Hello All,

On my Laptop I run Firefox and Ivanti VPN for Customer stuff.

I configured Firefox to use the Windows Network (so proxy) configuration.

When i start the Laptop, so no VPN enabled, and open Firefox. all good and fine.

I enable VPN, Firefox does not load any page, other Browser do. My manual workaround is now, to open the Firefox cofniguration, goto the Proxy settings. Then disable Proxy config, close the Proxy config, go back in and select System defaults. I found online, that this is an old bug and my co worker do not encounter this.

My Firefox has version 119.0.1 (64-Bit)

Thank you in advance.

So I've scoured the Firefox community help and have done everything: disabled cookie auto-delete, make sure I have "always use private browsing mode" unchecked, make sure Firefox always saves logins/history/etc., have security set to "Standard," and have added exceptions to the Firefox security; yet, despite all this, I'm still getting logged out everytime I close the browser. I'm getting to my wit's end!

What else can be done to fix this? It's really frickin annoying having to sign back into everything, everytime I open Firefox. Thank you in advance.

Firefox has been crashing multiple times per day for several weeks now. It used to be fine, hardly ever crashing. I can't think of anything I'm doing differently since before the crashes started. I can only assume that it started after a specific Firefox update. I do have a lot of windows/tabs open at once, but that was never an issue in the past. Occasionally individual pages will crash, usually several at once. The entire software crashes all at once regularly as well. Sometimes the crash seems to cause other issues, such as my computer hanging up for a bit, or my monitors going blank and the graphics system seeming to reset, before Firefox actually crashes. I don't always get a crash report dialogue when the whole thing crashes.

Most recent crash report ID: bp-bd37576c-c5ef-419f-a031-fe1910231123

I keep my Windows and Firefox up to date. I tried turning off hardware acceleration, but I think that might have made it worse so I turned it back on. I cleared the caches (which took well over five minutes), and ran speedyfox a few times. I exit Firefox through File > Exit whenever I need to restart or run other heavy software.

I have some .htm files which are stored in the root / directory and I would like to know how to access them in Firefox, running on Xubuntu 22.04 LTS

Interestingly enough, I found a solution here: Firefox Quantum: HTML files from internal (/usr) do not open which did solve my issue on my Virtual Machine which is running the same Xubuntu 22.04, however since performing a clean installation on a physical machine the same solution has not worked and I just get the follow error as shown in my image.

Despite removing the snap version of Firefox and performing the installation shown in this guide: How to install Firefox deb package, my physical machine just cannot access my local .htm files.

This has never been an issue for me on RHEL environments, and the file path syntax I am using is: file:///my_dir/my_dir2/index.htm

The directory permissions are: drwxr-xr-x root root

I had to reinstall the Rakuten extension button recently and it wasn't working right. I'm pretty sure it has to with Firefox Private Browsing mode which I have temporarily disabled for now and the Rakuten button works fine.

I would really like to continue using Private Browsing mode for Security purposes. I know there's a workaround because I had it working before, I just can't remember what it is.  :)

Hi ,

I tried to activate my firefox account on my new laptop. I also tried to add this new computer to firefox sync. The system shows me, that I am logged in with both my old and new computer After entering the password I am told that firefox account will sent me an e-mail to verify the account. I am told that I will receive a code at my e-mail address. The stored e-mail address is correct. I am told that the e-mail has been sent to my e-mail address. I have tried to receive an e-mail from my old computer as well. Whatever I do even after I added accounts@firefox.com into my contacts. I still don´t receive any e-mails with verification codes or links to verify my e-mail address. I really don´t know what else to try. I did not find any support adresses for firefox in europe. Please can anybody help.

I have the e-edition app for my newspaper on my PC. This allows me to read an electronic version of our daily paper. One feature of the app is to be able to print parts of the paper such as the crossword puzzle. When selecting to print the selected section, the section displays in a pop-up which it should. However recently when using Firefox the pop-up displays twice. And when printing again, the pop-up opens three times and then four times and then five times. I can get it to print ok from the last displayed pop-up and then I just have to close all the other pop-ups.

When using this app with Google and Edge this does not happen so I was wondering if there is a setting in Firefox that needs to be changed. Turning off pop-ups doesn't help in that I get the same of screens displayed telling me pop-ups have been disabled.

This odd behavior only began a few weeks ago.

Thanks, JB

Hello!

I have the problem that every of my most visited sites are loading normal fast except for YouTube.

YouTube needs about 2 to 3 seconds to load the site itself and the thumbnails like "lagging" pictures which are rendering real slow while my other most visited sites like Twitch, Reddit or Twitter are loading in about 1 second or less. (i have installed the "Page Load Time" addon to check that).

I have only installed uBlock and nothing else.

We have 2 desktop computers, both on the same wifi internet wireless network. On 1 we can ad the Ublock Origin extension no problem. But except for only 2 times, the other computer says installation aborted because add-on appears to be corrupt. Like I said, we have gotten it to load twice but both times it disappeared and now it won’t load. I’m not sure how it can be a connectivity issue, since they both access the internet from the same source. Is it that the problem system has Window 11 and the other 10? Why would it install twice and then disappear? Note that as a test I have uninstalled Ublock and then reinstalled it no problem on the Windows 10 machine. Does anyone know how to fix this? Thanks.

Hi

I access and log in to https://rdweb.wvd.microsoft.com/arm/webclient/index.html using the Firefox browser. The page displayed sometimes gives a feeling of very high contrast. Browsers based on Chromium do not have this problem. Do I need to modify the rendering method like WebGL in about:config, or change configurations related to the graphics card?

Best Regards

See the attached .gif in the past could I use a "mailto:" link without problems, I used this extension: https://addons.mozilla.org/de/firefox/addon/outlook-com-mailto/ But even, when I deactivate it, does it NOT work. As you can see in the gif, the website opens and the mail does not load. usually it should create a new empty email ready to send. I tested it with gmail (because I have a gmail accunt through google) and that worked.

So there is some problem with outlook, this does happen on every page, tested also with disabled adblocker (ublock).

My wife was on Firefox, I was on EDGE for email(Outlook) and google access, I tired of the issues with EDGE and moved my account to Firefox, it REMOVED her email access displacing with mine, how do I get her email access Back?

A while ago, I had a problem with Firefox where it was crashing every time I tried to open it. The solution was to rename the application, and then it worked. However, every time Firefox gets an update, I get the same error and have to reinstall Firefox and rename it again. The error states: "Error: Platform version '120.0' is not compatible with minVersion >= 119.0.1 maxVersion <= 119.0.1" I would love to either find a way to fix Firefox crashing normally that doesn't involve renaming it so that updating Firefox will work properly, or find a way to fix this error and not have to reinstall and rename the browser every time it gets an update.

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

Other browsers and programs manage to use the web just fine, but lately, firefox is hanging for minutes at a time, spinning its wheels, when I try to do anything online. It happens multiple times per hour, for several minutes. No idea what is wrong. I tried everything firefox recommends. Nada. Anybuddy have a clue? About to go back to the darkside, chrome. This is maddening.
