Hi

I recently updated to 78.10.0 vers and now when I try to play Netflix I get the WidevineCdm crash message and Netflix won't play

I have refreshed Firefox and restarted my Mac several times and disabled the Adobe Shockwave player.

Nothing works.

Can you please help me?

Hi everyone,

it's been 2 days now since every time I open Netflix and Amazon Prime videos won't play. A yellow bar saying: "The WidevineCdm plugin has crashed" keeps coming up!

I'm using Firefox and I'm on a MacbookPro.

I've tried everything: restarting/shutting down device; reinstalling Firefox; deleting widevine folder and activate it from the adds on page; tried on other browsers (works on safari but not on chrome); contacted Apple / Netflix / Amazon / Google nobody was able to help; I also ran these websites with my Mac in safe mode...nothing was able to resolve it.

What can I do to fix it please?

This started to happen out of the blue...I haven't installed anything! It was working fine until the day before...

Each of the threads below is someone reporting the same problem (which I also have), with the same timing. Suddenly on 21 April 2021 all (?) major streaming sites started to give "The WidevineCDM plugin has crashed" message and ceased to work .

No suggested fix works. Reinstalling does not help, toggling DRM application does not help. It was obviously the update (at least for users on 78.10.0esr with OS X 10.9.5) that did it. Is there some way to get this registered as a bug?

Why would a sites display language change like the link below? It is HP's website so I'd assume it is reputable. https://parts.hp.com/hpparts/Default.aspx?mscssid=&cc=CZ&lang=CS&.... (image below too) I was browsing in English, it changed czech on that page, and then back to English on the following page. Should I be concerned?

Hi, I've tried enabling Java Script but I must have chosen one of Firefox's browser extensions that is blocking it. I just don't know which one. How do I see those and make changes?

Thanks

Several days ago (approximately 12-3-20) my Internet Download Manager add-on stopped working. Removing it and reinstalling it by using a link provided by IDM does not work. It will work only if I open the webpage where I intend to download (e.g.--YouTube) BEFORE I reinstall the add-on and only for as long as that page remains open. Closing the page and then reopening it somehow deactivates IDM, as it will no longer link to the video I want to download. Have tried everything i can think of to solve this, including deactivating all other add-ons and by uninstalling and reinstalling the IDM program itself. I also unchecked the "block popup windows" management tool within Firefox itself. Anyone have any ideas what is happening? Initially, I also received the error message added below, but as far as i can tell, none of my other programs are set to block IDM. The error message no longer appears.

Hi Firefox Team

I am very happy to use this browser as it serves all my needs perfectly! So thanks you for that.

The issue I have is about the updates. Whenever Firefox updates, I lose the sites saved on it. I have no issues with that.

However, can you give me the option to select a time and date for it?

That way I can, 1) Select a time when I am not working on Firefox. 2) Coordinate with other updates like Windows and McAfee.

This will ensure that I am prepared for the sites to disappear just once, instead of every time there's an update.

Thanks, Kajal

# My problem

When i go to some site with video (for example https://www.openproject.org/ ) i have the following message : "To play video, you may need to install the required video codecs".

# Spec

I run Firefox Beta in Fedora, it's installed in /opt/ folder. I have the "normal" version of firefox too and the video works well.

# Some other infos

The video seem to be a mp4 video and i have the following package installed in my fedora GStreamer Multimedia Codecs (Multimedia plauback for APE, AVI, DV, FLAC, FLX, Flash, MKV, MP4, Speex, VP8, VP9 and WAV).

The ability to edit and customize the headers and footers for printing was one of my main reasons for switching from Chrome to Firefox. Now I can't find where to do this. I don't know if it was a recent update or what but I am using Windows 10 Home. Please help so I don't have to find a new browser.

When I attempt to access several websites, I am prompted to turn off my ad blocker. As I have not added a third-party software or extension that does such, I assume it is part of Firefox proper. Search as I might, I cannot find any specific reference to such a thing in "Settings". SO...how can I temporarily disable the 'Ad Blocker' device that is part of Firefox? The 'TEMPORARY' part is important, as I do greatly value the function!

How do you access Mozilla VPN after you have logged into firefox account - it only shows how to download and I have already downloaded it. I simply want to turn on the VPN and select the location but no instructions are available for this or at least the instructions are not clear.

I need to continue to use an application (Web Site) built with Flash Player for the first 3 months of 2021. Flash Player support ends on December 31st 2020. What is the plan at Mozilla in terms of restricting access to Flash Player in 2021? - For example, is there a timebomb in the browser so that Flash Player will seize to work on December 31st? - If not, would Flash Player become inaccessible following the first browser update in 2021? If yes, do we know when date is scheduled for approximately? - Will the behavior be the same for all Firefox versions (Light, Enterprise, iOS, Android, etc..). Thank you!

Why can a stupid failing script on a web-page, or even intentionally so programmed script disable the copy (and sometimes paste) functionality?

How can this be disabled/fixed?

One highlights a text (any text) on some web sites, Edit menu allows Copy, context menu allows Copy, one hits Copy, nothing happens. It's not even a page where someone wanted to "copy protect" some information.

Copy and Paste should work just as advertised since those were invented, how hard can it be to get that right? Even stupid Notepad never fails at it. And no, I don't care what the idiot who programmed a page though would be/should be best for me, I want Copy to be copy, Paste to be paste. This used to work in "original" Firefoxes even when page developers wanted to make it not work.

And yes, while on a given page Copy fails miserably, at the same time in other pages it works.
