I have been a "light theme" user for 15+ years. Since updating to 96.0 today, a dark mode spreading across Firefox has been forced onto me, including:

  • New tab background
  • Background of any tab waiting to load a page
  • Google/Youtube background
  • Settings/add-ons/password menu backgrounds
  • Automatic username/password drop-down background
  • Background of the little box that appears on the bottom-left (the one which shows the URL when you mouse over a link)

I am unhappy with this and wish to have my usual theme back. Can anyone please assist?

(In addition, there is some sort of white border around the current tab, which I do not like)

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.

Prior to FF97 a simply setting to "false" the about:config, print.tab_modal.enabled setting allowed FF to always use the system dialog box when printing. However, in FF97, this is no longer the case. How can I set FF97 to always use the system print dialog box??

I almost always use Preview printing on my Macs to avoid multiple pages of garbage so this is fairly important to me...and it might help to save a few trees...

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 made a post the other week about issues I was having with Firefox & YouTube.

Having put the browser in safe mode I discovered that it was my ad blocker/s. That said, I had notice Firefox lagging or loading hard on video sites, not just YouTube as well as some applets on other sites. And having experimented with various ad blockers and video sites as well as my own blogs, I find that I am not having these problems with ad blockers in Chrome or Edge, but only Firefox, so much so, that most of these sites are entirely unusable unless I disable the ad blocker/s in Firefox.

Frankly, I've been noticing it for some time, but as of the other week they have nearly rendered the browser unusable, or the ad blocker/s unusable in Firefox on said sites. I have completely uninstalled and reinstalled the add-ons, from the Mozilla site, to no real avail.

It is not only annoying but very frustrating and I am about to give up, on the browser altogether. I am not having these problems with the same ad blocker/s in Chrome.

I've spent nearly two weeks on this and it hasn't gotten better.

There it is. Thank you.

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!

I noticed today that all my color PDFs are viewing as black and white. For years they were fine, presenting as color. This is a serious problem, as I am a graphic designer and have many PDFs on my portfolio. I am also seeing the same problem with PDFs linked to my clients' sites.

Images on PDFs are still in color. It's the flat color graphics created in InDesign exported to PDF. Oddly enough, gradients (originally created in InDesign as well) are still presenting as color, but only the gradients.

I do not have this problem in Safari, nor in other browsers, but Firefox has been my go-to browser for years. I never had a problem until I noticed today. Firefox updated two days ago. I'm on a Mac and I now have Firefox version 102.01, as it updates automatically.

Thank you for attending to this issue.

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.

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
