Firefox Community Forum

I am using Firefox Beta 156, Version 4 on Windows 11 Professional, 25H2. I have an odd error, "Look up over IPV6 failed lookup." It occurs on two different VPN's, Proton Free, and Windscribe Professional. Any assistance, or insight would be highly appreciated. Thank you kindly.

On the Firefox mobile app, closed tab groups still count toward the open tabs count on some screens. This is frustrating as someone who likes to keep track of my open, active tabs accurately.

Not sure if this is an intended feature or not, but it is frustrating nonetheless.

i have made sure that all the settings do not force signing out, all settings include save passwords/bookmarks etc.

But... when I close firefox Im forced to sign in when I reopen the browser, it also looses all my bookmarks and passwords and I have to re-import them from the firefox backup.

I have deleted various temp files and force firefox to create new ones.

Can't get around this. It becoming such a farce that I'll abandon firefox and go to Opera!!!

I cannot change the location the built in VPN uses from "recommended". There doesnt seem to be other options for me to select. I'm aware the feature is still in beta, but this seems like a core function that I just can't use for some reason.

Someone claiming to be with Microsoft froze my computer until I answered whether I wanted them to know where I am at. I need protection from hackers like this. I want to be able to do a full scan on my computer.

Every time I manually update firefox, it reinstalls the automatic update malware "Mozilla Maintenance Service". I can't stop this malware from being installed with my browser every time I update Firefox. I call it malware because its not wanted, and it behaves like malware by secretly downloading content without my consent and then shutting down my browser when it finishes by blocking access to all new tabs.

I've tried adding policies to stop auto updates, but Mozilla Maintenance Service ignores all policies. I'm going to see if I can contact AVG and explain to them that Mozilla Maintenance Service is malware and see if I can get it classified as such to see if that'll finally get through to someone because I'm sick of this crap constantly being installed and forcing things on me whenever they want and not when I want.

Now after this update, every google search forces open my location service trying to force me to give location rights. This update is even more malware than all the other updates before hand. Firefox is getting extremely dangerous.

Does any of the mods know when the VPN for android will be available in the rollout regions ? I tried to connect and the toggle is now greyed out showing connecting..... Thank you

Firefox is screwing my display with a screen logging warning message. Removal instructions are 100% useless.

This is so annoying. I’m sure its simples if you’re a techhie, but for muppets its hopeless, I’m desperate for a solution as i cant use Firefox now

Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

I paid for an annual subscription of Mozilla's VPN on 9/8/26. However, when I try to run the VPN, it is telling me I have to wait for the monthly trial (which I had previously to reset). My invoice is 98Z6LFXQ-0001. Also, when I printed a receipt of my purchase, I noticed my zip code is incorrect. My zip code is 11224 (not 11229). I saw that it could possibly take up to four days for my purchase to be reflected, but I wanted to get ahead of this potential problem ASAP. Thank you!
