Firefox Community Forum

I'm a bit puzzled here. Initially, I tried to use the new built-in VPN for only a single domain. That doesn't work at all. Until it does, I tried to get it through other ways. Containers don't work, private windows neither, they both just inherit the global VPN setting.

So I moved on to profiles. The web found me a Mozilla support topic that suggested to open about:profiles and create a new one. Did that, opened a window for it, but couldn't get it to reopen on any easy path, just through opening about:profiles and clicking one of the many buttons again.

Then I found another description that used the "Profiles" menu. Never seen that before (probably because the menu bar isn't visible by default). Created a new profile there, too, and opened it. After restarting Firefox, all was gone! My original profile with everything was totally inaccessible, like a full data loss. Google search AI in a Chrome browser helped me out and explained what I need to do (in about:profiles, select the old one as default, then restart) to get my environment back. After that I deleted all newly created profiles and then their directories again.

Started over with a new "new" profile and continued there. Now I wanted to activate the VPN in there. It asked me to log in again, which was a good sign because finally I got a Firefox window that didn't know about the other window. But then the next failure: I couldn't log in with my credentials because that profile was already used in the other window/profile. Again, they're not completely separated from each other and there's some hidden link between them.

So, do I need a new Firefox/Mozilla account only for a separate Firefox profile? I can happily use my one account on different devices but not on the same device? Can I unlink the main profile from my account again? I don't see a logout button anywhere, I'm just logged in invisibly.

I am receiving "The page isn't redirecting properly - Firefox can't connect to server" error messages. This happens on nearly every website repeatedly for the last six? weeks. It does not happen in other browsers i.e. Chrome. I click the "Try Again" button in the Firefox error msg popup window over and over, 3-14+ times, to get past the error msg and access the site. When I try to login to many sites I am kicked out to the same error msg. Also kicked out of sites randomly when trying to navigate to another page on the same site. I had Claude AI take me step-by-step through all of the trouble shooting and adjustments to various settings. All of my extensions are off. I have had my ISP re-initialize my modem and I've run antivirus scans, still the problem persists. (Strangely YouTube does not have these problems) I love Firefox. I've got it setup just the way I like it. I have been using it for 20 years and during those two decades Firefox has been stable and had only minor glitches. I do not want to change my browser. Chrome feels clunky to me. I'm attaching three representative screen captures of the error msgs. Looking forward to anyone's help.

Earlier today the audio on Firefox stopped working. I have tried disabling extensions, checked output devices, reinstalled and it still doesn't work. Please Help. The Version is 150.0.1

Hello, I am experiencing an issue where the built-in Firefox VPN feature has completely disappeared from my browser interface. I cannot see the icon on the toolbar, and the feature is not active. Could you please clarify if this feature has been geo-restricted or temporarily disabled for certain regions, or if there is another hidden preference I need to modify to restore it? Thank you for your assistance.

Issue Summary: When disconnecting from a corporate Cisco AnyConnect VPN on macOS, Firefox completely loses its internet connection and throws network errors. Other browsers (Chrome, Safari, Edge) continue working perfectly on the home network. Standard troubleshooting steps—like clearing Firefox's DNS cache, changing proxy settings to "No Proxy", turning off DNS over HTTPS (DoH), and flushing system DNS—do not resolve the issue.

Root Cause: Cisco AnyConnect locks low-level socket configurations and routing rules within the active Firefox user profile (prefs.js). Even after the VPN is disconnected, Firefox remains bound to the dead corporate pipeline, a behavior that standard settings menus cannot override.

Proven Solution: The only way to clear the corrupt VPN socket locks is to completely reset the internal profile architecture:Open Firefox, type about:support into the address bar, and press Enter.Look at the top right of the page and click the "Refresh Firefox..." button. Accept the prompt. Firefox will close, securely back up your bookmarks/passwords, generate a fresh profile, and restart.Internet access will instantly return to normal. (Note: You will just need to reinstall your extensions afterward).

From Firefox, I have launched Earthlink Web Mail. When reading an email, scrolling doesn't work. It worked yesterday from firefox. It works today on Edge. It works today on my Android phone.

Hello,

I'd like to report an issue with a recent Firefox update.

Since one of the latest updates, the "Close all duplicate tabs" option has disappeared from the tab list menu (the menu opened via the small arrow on the right side of the tab bar). I've looked for it elsewhere in the UI and haven't been able to find it.

System info:

Firefox version: 154.0 (64-bit) Operating system: Windows 10 Professional, version 22H2 (OS build 19045.7663)

This feature is particularly important to me because I regularly keep a very large number of tabs open — often several hundred, sometimes over a thousand — and being able to close all duplicates at once was essential for managing and cleaning that up.

A couple of things make me think this may be an unintentional regression rather than a deliberate change: Mozilla's own support article on the Tab overview menu still lists "Close all duplicate tabs" as part of this exact menu, and I couldn't find any mention of its removal in the release notes for the two most recent versions (153.0.3 and 154.0). That said, I haven't found an existing bug report that matches this, so I wanted to check here first.

I'd really appreciate help with the following:

Why has this option disappeared from the tab list menu? Is this an intentional change, or a bug/regression? Has the feature simply moved somewhere else in the UI? If it's a bug, is there already a tracked report I should follow, or should I file one?

Thank you in advance for your help — this was a feature I relied on daily.

Firefox prompted me to update, I hit download, my entire PC froze, I restarted the computer, when I opened firefox again and hit "restore session" it restored a session that I had opened months ago. When I checked my history, everything after that older session had been deleted. All of my history from the past few months has been deleted. I tried a few different solutions from trying to research the problem, nothing so far has worked. The only thing I have found is a session restore error saying "could not decompress file", but I could not find the file it was attempting to decompress. This is the error message I found.

1785894397652 SessionStore ERROR NotReadableError when reading session file: recovery: NotReadableError: Could not read `C:\Users\ansen\AppData\Roaming\Mozilla\Firefox\Profiles\xpnhovd6.default-release\sessionstore-backups\recovery.jsonlz4': could not decompress file: invalid LZ4 header: wrong magic number: `00 00 00 00 00 00 00 00 00 00 00 00' (NS_ERROR_FILE_CORRUPTED) No traceback available 1785894397756 SessionStore ERROR NotReadableError when reading session file: recoveryBackup: NotReadableError: Could not read `C:\Users\ansen\AppData\Roaming\Mozilla\Firefox\Profiles\xpnhovd6.default-release\sessionstore-backups\recovery.baklz4': could not decompress file: invalid LZ4 header: wrong magic number: `00 00 00 00 00 00 00 00 00 00 00 00' (NS_ERROR_FILE_CORRUPTED) No traceback available

Any help is greatly appreciated. I'm one of those people that tends to have way too many tabs open at once due to poor memory, and losing months of tabs and progress is a huge setback. I'm very desperate to get the history and tabs back.

Hi all. I can tell from a quick google search that this question has been asked MANY times, but I can't find step-by-step instructions for noobs like me who are new to the advanced features utilized to fix this issue. Please, if you wouldn't mind... Can someone provide step-by-step instructions to help me resolve this? I'm running version 154.0.1. I don't want to delete the bookmarks themselves; just that list (permanently). I appreciate your help!

Hello Everyone,

I now do have the VPN button on my toolbar but when I click on "Turn On VPN" nothing happens. I am logged in in my Firefox profile through the VPN settings under Privacy and Security.

I am on Mac OS 15.7.7, Firefox 151.0.1.

Why am I not able to turn on the VPN?

Thank you.

Hey guys, so I always have a bunch of tab groups as it helps me organize my tabs. But every time I accidentally close Firefox or my pc resets, all the tab groups are gone. UNLIKE google chrome where, even if I close chrome they will be on the toolbar for me to open again. So could you please add this feature on firefox as well because this is getting very irritating because I have to open the individual tabs again and again? Thank you.

I have custom userChrome file that made my history and hamburger menu (application menu / settings) text and distances smaller since Firefox introduced this ugly feature, trying to be cool in windows 10 times. Nowadays even windows 11 brings back compact mode but firefox still uses huge spacing. I just fixed issue with custom CSS and forgot about it. Unfortunately, after updating to FF 151, my CSS is ignored and I am forced to new ugly context menu. What is weird, I still have good small pacing when right-clicking pages, UI elements and when I enter bookmarks. Only places that ignore my CSS are hamburger menu for settings and list under history view. I do not really understand this code, I just copied it from someone else. Can someone help me fix this issue?

Je ne peux plus accéder à Facebook sur l'ordinateur. Attente éternelle de la prise en compte des mes codes. Alors que j'y accède normalement sur mon téléphone portable et sur ma tablette. Je suis protégé par Bitdefender. Quid ? Merci :-)

Issue persists on Incognito Mode and it goes away if I use different browser.

Since 2 days issue like this happened and it is retroactive meaning all previous conversations are also blank, all replies of chatgpt are blank except replies with image generation, those are fine.

Before you recommend me to do something please keep in mind that Incognito itself does not help.

I am able to share that chat, paste it in my firefox and page is blank. https://chatgpt.com/s/t_69f4b354cc188191a7959c2d443fed9d

I can use this adress on different browser and it works fine

I'm trying to add the world cup tracker to my home screen, but when i click the link, it just puts me in my new tab page with no changes. When I click the pencil edit icon, widgets are not an option for me. Is there a place I need to enable them?
