This happens far too often, in the course of 9 months or more frequently. What is going on Firefox? v88.0.1 Windows 10

Constant script errors that freeze whatever program I am in, regardless of the option I choose - the popup no longer gives me a WAIT or STOP IT. The box comes up that says DON'T ask me about this again.

I do not want to copy passwords, more than anything, should I create a new profile. I do not want to deal with replacing or losing the file. When I attempted to load two other profiles over the last two days, both times FF crashed. I gave up.

I am NOW in Safe Mode and without errors, and it's hard to know which app is causing the problem.

Is there a new addon that will back up Firefox these days?

Suggestions? Seriously, FF seems to be a whole lot more trouble these days than she is worth.

Thank you.

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?

I have reduced modifications in about:config as much as I can stomach and also tried disabling all addons.

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...

Hi everyone,

After the 85.0.0 update and still now with 85.0.1 and 85.0.2 firefox crashes. It's usually happened with clicking a link that'll take action outside of firefox (not a url link but a download attachment link in gmail or a print link). I've also had it happen with placing links from the search bar to the bookmark bar, and just recently opening up the 'show all bookmarks' window.

It'll hang, i won't be able to click anything, and then it'll give me the 'close window' screen. It's never fully crashed and given me an error message. I start up firefox again, restore the session and everything is back to where it was.

I've tried refreshing. I've tried creating a new profile. I've tried uninstalling and downloading 85 direct from mozilla. Nothing seems to be working. I'm going to see how it does for a bit in safe mode, but all the add-ons I have I've had way before the 85 update and all of them are recommended by mozilla.

I'm all ears (eyes?) for solutions!

On another user's account, cannot go back to earlier FF version, profile files missing. Cannot start _any_ revision, old or current (using OSX Sierra on that user & different FF versions - the shared data you see her is NOT the same ) details here: https://support.mozilla.org/en-US/questions/1356226

I don't see the profiles.ini and installs.ini files within the Profiles folder. I see the general format from looking at good ones in my own Profile.

Don't understand why some are "locked."

How do I re-create them using the existing Profile names, and how do I denote which to startup using (the default folder?) Can't find any Help files to explain.

This is driving me mad, we are using the same physical computer because mine broke, so I start it up off an external drive containing my drive, then I have to shut down & restart on the internal drive to work on it, but then I don't have access to my saved files or to post on the forum.

After some time of usage, Mozilla Firefox doesn't send HTTP requests when the user asks for a web page to be loaded.

Hi. Problem description: - After some time a tab is opened I can hit any link on current web page but Firefox don't load it. - It shows the loading progress but newer show the requested page. - Going to safe mode (disabling all plugins and extensions) doesn't solve the issue. - Reinstalling Firefox doesn't solve the issue. - Restart Firefox solves the problem but after 10 - 20 minutes the issue comes back. When I leave some opened page in some tab it stops responding on hitting any link on it. - The most strange thing when I disconnect the network adapter the page immediately appeared on the screen, but mostly as simple text, without any pictures and styling. -After connection back to network everything works for some time (10 - 20 minutes).


I have verified that Firefox doesn't send a HTTP request in the moment of hitting some link on web page. The request is sent after 10 seconds, sometimes after several minutes after, nevertheless the requested page doesn't appeared at all. I used Process Monitor from sysinternals.com to see Firefox communication.

First screenshot I made after hitting link "deleting your user account". After approximately 7 seconds Firefox starts communication with github.com. The requested page didn't appeared during 2 minutes. https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2021-04-29-12-06-06-96a3be.png

Next two screenshots was made after I disconnected a network adapter. https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2021-04-29-12-14-07-a2ef40.png https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2021-04-29-12-15-15-e45ee7.png

Before shutting down Firefox I deleted history/cache/passwords etc from the past day

I do this all the time but since I had restore previous tabs selected they always get restored when I start up again

However this time they weren't restored when I restarted

Without closing Firefox I navigated to the sessionstore-backups folder to see what was there but the files were only 2KB - much too small for the number of tabs.

So I installed ShadowExplorer & Shadowcopyview to see if I could recover older versions I was able to locate jsonlz4 files from a few days ago that were around 11000KB in size so I assumed they would have most of my tabs

However when trying to use the files nothing happens - I tried 2 different steps that I read here had worked for others

1 - Renaming previous.jsonlz4 to sessionstore.jsonlz4 , moving to the profile folder (deleting the old one first) and restarting FF

2 - Deleting sessionstore.jsonlz4 and copying the recovered previous.jsonlz4 / recovery.baklz4 /recovery.jsonlz4 / upgrade.jsonlz4-20201014125134 files to the sessionstore-backups folder and restarting FF

I also repeated the steps after creating a separate profile

None of these worked so I tried examining the jsonlz4 files using https://www.jeffersonscher.com/res/scrounger.html but I got an error message 'Session history file contents could not be read?'

Now I've previously used recovered Jsonlz4 files to restore tabs with no issues but this time they won't work

I read here https://support.mozilla.org/bm/questions/1189759 that updates may cause compatibility issues and the upgrade.jsonlz4-20201014125134 file indicates they was a recent update

The recovered file sizes indicate they contain data so I want to know how I can recover it - if not through FF then through some other software

My Firefox browser seems to have reset itself to Windows 8 compatibility. I have Windows 10, 64-bit. Firefox will not open full screen, but opens a tiny, narrow window at the bottom of the screen which I have to use task manager to close. I remember one of the automatic updates coming through a few days ago.

Can I do anything other than uninstalling and a new install? I'd like to keep my favorites list, etc. I am at the extent of my computer skills with this.

My download library window used to display files well over a year old, everything I have saved since the last time I deleted all browser history. Recently, everything older than six months was no longer displayed. The files are still there, I just have to search for them. Now it no longer shows anything older than 4 months. "Show all history" does not work. Is there a way to restore that list?

After the update that changed the bookmarks menu spacing in the most unhelpful way, I have reduced this stupid double padding between the folders with a hack - an now with the current update to 91.0.2 - it is back on!!???

Whose idiotic idea it was without giving us the OPTION of single OR double padding??

Why do we have to look online for the hacks and workarounds to remove this most idiotic and controlling change??

Please bring the single padding back NOW or I will completely switch to Chrome or simply will stop updating firefox!

You will NOT control how many folders and bookmarks I can see in my top menu bookmarks - and this idiotic double padding has removed half of them from my menu!!!

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!

Hello there to anyone who can help me with this problem that I'm having right now. Yesterday while watching and going through the videos on youtube, while watching a video, it suddenly started to lag and not move as smoothly much as before when I have on a higher quality like in 1080p 60fps or 720p60fps.

This has happen to me a couple times before when I couldn't find a way to fix it like when my my laptop was acting stupid and was resetting itself and showing a blue screen when it happen and had someone help me take it to the store and have it fixed and the reset my laptop or something and had to go redownload Firefox and I think the problem stopped working.


Yesterday and today I tried searching and looking up how to fix this and find answers that tell me to go to the about:config and change somethings to false or true whatever and it still has this problem. I hope changing it to whatever doesn't mess it up anything even more.

I thought I had to go update Windows or something since recently a couple of times the youtube videos get stuttery and not move as smoothly at times. I can't remember much this one but I either just close Firefox to hopefully that it goes back to normal or I have to update Windows to restart my laptop and it works and it goes back to normal.

But this time when I did all that and I try to update Windows from my laptop it was doing what it does updating installing or downloading yesterday. The problem is still there and the videos on youtube are still stuttering. And I try to see if there were more things to update there was nothing there and says its up to date.

I linked a video that has a 60fps option on a another browser Microsoft Edge to see if it works from there and video when putting it on 60fps works fine there. So this must be a Firefox problem or something.

So if anyone can help me with this problem. Please tell if there's anything else I can do to get these videos on youtube to work on Firefox in 60fps and hopefully can try to easily fix this and hope its nothing complicated to do. Or if there is a bug or something that's making these videos stuttering and everything please try to fix this problem that's going with me right now. Cause i don't want to have to deal with problem I had before again forever and/or if its permanent.

Hopefully maybe the next update for Firefox might fix this problem I have from these youtube videos, but I don't know. Whenever an update for Firefox happens sometimes, the videos on youtube start to stutter and not move as smoothly with putting it on 60fps and have this problem again.

Thank you if anyone has the time to look at this and hopefully someone can get me the answer to finally fix these videos that are freezing stuttering and stuff there.
