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.

HTTP/1.1 401 Unauthorized Server: Microsoft-IIS/10.0 WWW-Authenticate: Negotiate X-Powered-By: ASP.NET Date: Mon, 25 May 2026 08:15:41 GMT Content-Length: 0

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!

I'm on FF 154.0. The power went out here and when it came back and I booted the desktop computer something had changed in FF.

I used to see the active tab as green in the tab bar and yellow for the rest, but now they're all gray until I mouse over the bar and only then does it turn green/yellow.

I struggled with this for many hours trying many //active tab color// solutions I found in searches but nothing got it back to my old behavior.

So as a last resort I tried adding the Firefox Color extension, but when I click Add to Firefox it just turns into a throbber that never changes so it doesn't install. I'm stuck!

Frustrated!!

Accidentally told Fire-Fox to allow access to a website without two step authentication. I want to restore the ability to the website so the website requires a phone call to sign in.

Thanks in advance.

I have logged into TinyURL.com MANY times using Firefox. Now, I get a Cloudflare Validation Error when trying to do so (see attached screenshot/snip).

This was done in Troubleshooting mode, but is the same in standard mode, though I have no extensions enabled. I've tried turning Protection Tracking off; no luck. - We use ZoneAlarm, but the Web Secure functions are all disabled. - I have the same issue on 2 PC's, one Windows 10 and the other Windows 11, 64-bit. - I'm on FF release 150.0.2 - 64-bit, and both Windows installs are fully updated and kept that way. - I've reached out to TinyURL in hopes of resolving the issue. They suggested many of the above steps but not resolved this issue. - HOWEVER, I've found that login via Google Chrome IS seamless - no issues.

What is it with Firefox that it's having issues with the Cloudflare "Human" check? I've checked the Cloudflare site; all conditions are good, and this very setup passed the "Turnstile" check.

FF is my #1 preferred browser, so please look into this. I see that others have posted similar issues over multiple years here (but a search of support articles didn't find one . . .)

Thanks,

I can't access two websites in Firefox, but I can access them on my phone and in other browsers. One site is Facebook, and the other is https://www.gildertech.com/forum/

Thanks in advance,

I logged into firefox on new computer and synched but none of my bookmarks or passwords showed up -- what can I do to restore? Can I import them from iphone? Note that my old computer doesn't work, so I can't import files from it yet.
