Firefox Community Forum

This morning (08/28/25), I updated my browser to v142.0.1 (64-bit), and Facebook as well as other sites have been affected to the point that I can't even see contents now!!!!!!!

I (God forbid) opened the same sites in Edge, and there's no problem viewing them on Edge.

Is there a way that I can roll back this latest update, because I had no problems until this morning. I'm running a Win 10 Pro OS.

I want to unsubscribe form emails from a company MyHeritage, but when I click the link the page opens then instantly greys out so I cannot do anything. This happens with another trusted web site as well

I follow the instructions to pin an extension, but when I click on the jigsaw icon, I'm taken to the add-on manager page with the ability to review recommendations and manage the extensions and themes. There is no option to pin any extension. I saw this issue on an expired post to Mozilla but the answer was incorrect.

Any ideas? I can't access my password manager extension even though it's there....

Moving Firefox over to a new computer, I know how to find the profiles via file manager- that is not my problem. I am not sure which to move, Local or Roaming. I am thinking Roaming as that has all my bookmarks and passwords. I have moved individual files from Roaming and do have bookmarks and passwords working on new computer.

But I was thinking it would be best to move the whole thing so I got the tabs that should be used on startup and maybe more I don't know. So I don't know if I should copy both over or just one. I did try both once and Firefox said it couldn't find profile (I renamed the old ones).

Thinking I may need to use about:profiles and select new one. Not sure what will happen, hope it lets me point to new file on my USB drive. Looks like I should use both local and roaming, but don't know? Local might be something that relates to hardware on computer.

Hope this makes sense?

Ever since upgrading to Windows 11, my Firefox installation has occasionally been unable to resolve domain names of some websites. Example domains:

• apps.powerapps.com
• static.cdninstagram.com
• google.com

As I was trying to debug this, I discovered that the DNS resolution and connection timings are just over 30 seconds (see the attached image). This is highly unusual.

• The issue does not occur with other web browsers on my computer (i.e., Microsoft Edge).
• The issue has persisted across reboots.
• I have already reinstalled Firefox (and wiped the temp files and appdata profile before installing again).
• The issue does not occur with other devices on my home network.
• DNS over HTTPS has been manually disabled.
• Changing DNS resolvers in my Windows settings does not fix the issue.
• The issue is still present with a fresh, unmodified installation of Firefox.

Any help would be greatly appreciated! I love Firefox and do not want to switch to a different browser.

I am intermittently but repeatedly getting this message in Firefox:

> The Windows file-dialog has crashed. No file or folder could be selected.

Is this a known problem? And does it have a solution?

Hi, just to say, sorry, I’m an absolute idiot, I don’t understand tech at all. I have a VPN, privacy badger and ublock origin. These issues continue whether these three things are turned off or not, so I believe it must be to do with my Firefox settings.

Everything was fine, but now all of the sudden, certain elements of pages will not load.

So for example, today I tried to go to Gizmodo and look at a Star Trek page. Cool. https://gizmodo.com/star-trek-day-announcements-include-a-lego-collaboration-and-a-youtube-kids-series-2000655142

This is not the only site, just an example.

Clicked the comment button to see what people are saying. It won’t load the comments. The comments are completely blocked. They don't exist. When I try to look at the comments, it just shows me another part of the webpage, can't even see the comments.

Thought it was just this site, but then today I was on a plastic surgeon site in Europe to make a payment and it wouldn’t load the payment page.

I tried turning off badger and unblock to make the payment, and it didn’t work.

Honestly I really have no idea what the problem is, I know I’m doing something stupid but I don’t know what it is or how to figure out.

Any help on figuring out what’s going on or where the hiccups for these might be would be welcome.

Thank you!

I cannot log in to iCloud.com, even after setting a popup block exception. When I click on the "go" arrow after entering password, I get a notice on my iPhone to allow access. After I approve, I get a 6-digit verification code on the iPhone. But no popup window appears on the Firefox tab, so I can enter the code. Any suggestions?

I've been backing up my opened tabs for the past 4 or 5 years with the steps in this legendary post: https://support.mozilla.org/en-US/questions/1257866

But this time it failed me and I don't know why. I just switched from Debian to Linux Mint, put everything up to date, but when I copy the sessions-store folder back into my session folder, as described in the post, nothing happens. I tried restoring only the 2 files listed there, and also dropping them in the general user folder, outside sessions-store, but still nothing. I've also noticed that the sessions-store folder isn't created automatically, even if I open a bunch of new tabs now and close the browser.

I don't even know how to begin troubleshooting this to be honest, this is the first time this method's ever failed me :(

I also saw this post: https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup But it doesn't help either.

Google told me to go to About.Config, find "browser.tabs.showAudioPlayingIcon" then change the value to false. But, at least in my version of FF, that doesn't work because browser.tabs.showAudioPlayingIcon isn't listed. I'm running 142.0.01.

I know FF is trying to please all the wonderful teenagers who want to constantly screw around with software settings. But it would be really nice if such new "features" were not turned on automatically.

When I swipe to the left, Firefox navigates Back & when I swipe to the right, Firefox navigates Forwards. It is VERY ANNOYING!!!! It's really easy to do this accidentally while scrolling around a large web page. When you go back, it deletes all data that was filled out on the web form causing DOUBLE the work. How do I turn it off please? Win 10, FF 142.0.1 64-Bit

My primary google account's language is set to english. If I search normally, then the results are shown in english. If I open a private window and search in google, the results will try to be in the regional english and google asks if I want to switch to english every time.

This is a weird one for me. Firefox 142.0.1 Windows 10 Pro 22H2 AdBlock Plus and NoScript as add-ons

https://tvlistings.gracenote.com/grid-affiliates.html?aid=tribnyc2dl

shows me as automatically logged into the site but will not load the TV listings for me in a normal window.

But if I use the same link in a private window it asks for my user name and password then shows the TV listings and continues to work as it always has.

What could possibly cause this? Has only happened for the last 4 days.

Windows 11. I have my taskbar behaviour set to ‘Automatically hide the Taskbar’ So usually the Taskbar is not displayed, but when I move my cursor to the bottom of the screen it reappears. With Firefox I cannot make the Taskbar reappear.

I have these printers.

"HP LaserJet M109-M112" (the Windows default) "HP LaserJet 1020"

Regardless of the value of print.sav_print_settings, the first print dialog after starting Firefox shows "HP LaserJet 1020".

If I manually put "HP LaserJet M109-M112" (no quotes) in print_printer, it reverts to "HP LaserJet 1020" the next time Firefox starts.

How do I make "HP LaserJet M109-M112" Firefox's default? Thanks.
