Firefox Support Forum

I'm not able to stream any content on Netflix, Amazon Prime, channel 4, 5 using firefox. The error message is 'The widevine CDM plugin has crashed'. I looked up in preferences/ extensions and themes/ plug ins and it seems like the widevine CDM plug-in was automatically updated today (21.4.2021) and now it's crashing. My firefox is 78.10, the latest for OSX 10.9. Can anyone suggest how to resolve this ?

I have a problem watching video on Netflix and HBO Max. My Firefox is up to date and I checked my settings. But do I really have an up to date Firefox? Is that what's causing me to not watching a show or movie? Or it's a crash that can be fixed?

What can I do? Or what can be done?

Hi, I can't use Netlix since the last automatic update of firefox 2 days ago (78.10.0) - a problem with WidevineCdm. The message from Netflix : "Looks like your browser is no longer supported" and a popup yellow window "Le plugin WidevineCdm a planté" (=WidevineCdm plugin has crashed) Two errors codes, see in attached files

I had a lot of plugins that after reinstalling the operating system and logging in to the Firefox account. Too many of my plugins have been removed. I need them. How do I recover?

Its been happening for several months. I tried doing a refresh firefox and a safe mode firefox. Neither solved the issue. Screenshots attached. Mac OS 10.15.7 Catalina. Firefox 88

I thought my issue may be similar to: https://support.mozilla.org/en-US/questions/1308429

I don't need help with any particulary thing but I do have one curious question if I'm allowed to asky here? Sorry if im not suppose too. Will the new design eventually support compact mode becuase I love using that?

My Widevine CDM Plug-in just crashed! I checked my Firefox settings and it looks like the Widevine plug-in just updated late last night, and is up to date. I fear the new update might be incompatible with my Firefox 78.10.Oesr / or my OSX 10.9.5 but I'm not sure. I'm not a mac savvy person but I'm always ready to learn. Any help would be appreciated!

Since the update 78.10.0 yesterday I can't play Netflix or open facebook or messenger. Facebook only shows the first post and I cannot click on anything. Messenger is a blank page Netflix shows error NSES UHX which Netflix support says does not exist in their system

Today on my Netflix I received a "widevineCDM plugin has crashed" message. I went to the plugins and everything is updated even my FireFox. I have uninstalled and re-installed this app, but nothing has helped. Not sure what else to do. Any suggestions would be helpful. Thank you in advance.

Hi, thanks for clicking the post.

I have become very interested in the Logitech Craft keyboard. It has a wheel at the top left that has different functionality for different applications.

What I would want it to do is to be used as a simple scroll up/down in Firefox and other web browsers.

I have asked the community at Logitech's website and was told by a dude there that the Crown wheel in fact cannot be used as a simple scroll. Which seems to me like a major blunder as it is to me the first obvious thing for a wheel.

My question is if the information I got was incorrect. But if not, then I would very much appreciate if anyone here could tell me if there's any other way to get it, a simple scroll using the Crown wheel, working for Firefox.

Many thanks! Regards / B

Firefox 87 x86 "broke" yesterday visually. A lot of areas of pages and top area (Firefox menu area) turned black. Safe mode fixed the problem. I did not or could not see how to disable ext one at a time. I went with a "Refresh" when I was to uninstall and install. Now, FF 87 does not remember the magnification setting. I set pages to 80%, close, launch, home page (previously set to 80%) is at 100%. Pages that are bookmarked (just set to 80% prior new launch) launch at 100%. There a multiple times during the run time of Firefox that I had gone into config and made adjustments. I do not recall having to do so for magnification not being saved. I do notice that one config change made prior does not exist now, set resolution 1440x900. I think there was a true/false for page memory in config that I had switched from default before the refresh, but seeing how the screen resolution isn't 1440x900..I assume "Refresh" reset config to default.

Sum: Now, Firefox does not save page magnification. What do I need to do, other than 'bump' the size every time? This was not the case prior the "Refresh".

The menu was simplified but unreasonably inflated. So much so that we need Scroll-down to get down the menu.

I wonder if the menu will remain like this in the final design.

I use 3 profiles (work, private and media) side by side. When I open external links I have no control over which profile will open the link. The link is opened right away (so no profile manager interference) in a random profile. I do want it to open right away, but ideally would like to easily set a priority order for profiles to open the external links without having to restart the profiles.

I cannot find any specific areas in settings that show there is "ad blocking" options. I assume there is no ad blocking options without having to get an ad blocking add on, correct?

I have not been using Firefox long...I'm trying this out as I am used to Brave.

hi there!

is there a way to open a firefox tab in a new private window? it's something i'm wishing for all the time!

(google posts from many years ago state a way to select this option from the menu, but if it worked it no longer is in the menu.)

my reason for needing this so often is that i have many add-ons that block trackers, ads, etc, which are disabled for my private mode. so if a tab won't load, it would be the easiest way by far to get it to do so!

thanks for any help!

Hi, I have a sound interface on OS X 10.11 but firefox is stuck with an audio output pair which is not the one i picked on the system.

This results in all my other applications working fine (itunes, vlc etc) but firefox outputing no sound at all.

Do you know how to change the audio output for Firefox on OS X 10.11 ?

many thansks

Upgraded to a new Firefox version. Lost the ability to separate the Homepage from New Window behaviour. Is there no way to specify these two things separately? It seemed to be working fine when I first upgraded, but in the options it shows everything as "Blank Page", so if I want to change my homepage URLs, I have to set it to that and if I do that, it undoes the separation of the homepage and new windows and I have to go set it again in about:config...? One of my most used features was this separation of the Homepage with New Windows, gave me a lot of control.

Playing youtube video on Firefox has become a hazard. The power consumption sharply rises whenever a video is plying AND (specifically) when the this youtube tab is the one open (current). As soon as I move to another tab and let the video continue playing this problem disappears and resource consumption looks normal. Then if I go back to the youtube tab then it spikes again sharply.

It has been like this for a week or couple of days now.

I've been able to sync my firefox account on a university computer until 2 weeks ago. Now when i login to the university computer (in the classroom where I teach), my account "logs in" but nothing syncs (no bookmarks or passwords).

I haven't changed anything with my account. How can I access my synced info on this University computer?
