When a system-wide VPN application (not built into Firefox) is enabled, the behavior of the address bar changes: on the first click, it only shows 5 sites (Top Sites), instead of the usual 9. After pressing the Spacebar, the list from browsing history loads normally. The problem persists after turning off the VPN and only disappears after a full restart of Firefox. The issue is reproducible. Firefox version: the latest

Previous solution: switch browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false does not work anymore.

Please help.

Regards, Victor

I noticed recently that my 'Add Shortcut' button has disappeared. I've been through other articles and they were of no help. I have 4 rows selected for shortcuts so theres no reason for it to be gone.

Some websites won't load at all while other are very slow to load but some will load just fine, example Crunchyroll (screenshot attached) won't load at all its just spinning loading icon and a white page but if I try it in a different browser it works just fine, but with Youtube it will load but is choppy and low quality videos and same thing as before I load it in a different browser and no problems. I have tried every possible solution I can find from clearing cookies and cache to refreshing Firefox even scanned for malware and virus nothing has worked please help me figure out what is happening and why it's only with Firefox that I am having this problem and its not hardware can play online just fine and download games from steam perfectly fine.

How do I remove the pop up blocker on Firefox for certain websites? I am doing an online course and each introduction for each chapter has a short video that pops up but as soon as that happens Firefox sends a "Critical error" message then the video stops so I thinks that's happening because pop up blocker is turned on and I just dont know how to turn pop up blocker off for specific websites only like this one I am using for my study course. How can I turn the pop up blocker just for this one website so that this doesn't keep happening?

Hello I got a pop up or it was new tab informing about new firefox functions. It was about profile creation and management. Now i have two profiles and cant switch back to my old one. I cant seem to be able to delete new profile to return to my old one.

Firefox: Sprache ein Mischmasch aus Deutsch/Englisch. Trotz dass die Einstellungen nur auf Deutsch, sind die Menüs in Englisch! Wie bekomme ich es hin, dass ALLES nur in Deutsch ist?

I set the about:config settings when I got the new computer early last year. It's been working fine. Suddenly, searches are popping up again to the urlbar.

browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar is still set to false. Keyword.enabled is still set to false.

I see a couple of site references to browser.fixup.alternate.enabled, but it doesn't exist.

How do I get FF back to proper search in the search bar?

In my Firefox browser, when i try to sign in to Youtube, a window says "there was an issue signing in to Youtube" pops up. None of the troubleshooting articles are helpful for my situation. My Firefox browser is up to the latest update - version 146 on windows 11. Youtube works, but i am prevented from signing in to my account.

I have used Youtube in Firefox before by signing in to my google account, the only thing that has changed was that I went into settings and cleared my browsing history, cache, and cookies. Once those were cleared, Youtube won't sign me in and only shows that error window.

In my Firefox browser settings, I have set Youtube to accept cookies and have disabled adblock for Youtube.

My Youtube account is still accessible using Chrome, but not in Firefox. Youtube WILL sign me in if i use Firefox private browsing. I'd rather not use chrome since Firefox is my primary browser and I'd rather not jump through the extra steps of google sign-in using private browsing.

I do have a Google account with my school institution, but that has never been an issue (expect it won't open google maps for some reason, not the issue here though). My Youtube has always been signed in with my personal Gmail, not my school Gmail. I'm not sure if that's interfering with anything.

To reinstate the main issue: I cleared my browsing data and cookies, now Youtube in Firefox won't sign me in.

I can receive, but not send, emails using Thunderbird on my PC. I believe this problem began when Thunderbird was updated on 1/13/26. I have no problems sending email on my tablet.

My service provide does not support TLS 1.2, so I tried changing security.tls.version.min to 1. This did not help.

The attached shows the error message and my SMTP settings (1st image) and my service provider's email server settings. I tried changing the SMTP port to 587, but this resulted in a time out error.

Any help is appreciated, Norm

I signed into my firefox account on my wife's computer and now ALL of her bookmarks, passwords are mixed in with my data. I've signed out of both accounts on that computer. I've signed out and relogged in on my computer. This is not a temporary issue. All of her data is somehow in my account. This seems like a MAJOR security flaw of the software. Were both using Windows 11 computers.

I can't re-open a saved tab group. I saved it and closed firefox but when I returned I couldn't find where to access it. I see all of my saved tabs when I right-click on a tab and choose "Add Tab to Group", but when I move the tab to that group it just disappears rather than open the group. Any help would be appreciated! :)

Svp, comment changer la couleur de la barre latérale ?

La mienne était toujours blanche, mais vient de changer à mon insu pour du bleu ...

Merci de m'aider.

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.
