Firefox just updated to 152 this evening on my Windows 11 Pro system. It seems slow compared to prior versions. Also , every time you log out , it crashes and activates crashreporter which files the report. Any clues? Nothing changed on the system except for Firefox.

For some reason, I am locked out of signing in to Mozilla VPN. I have twice changed my password & recovery key, & then been returned to the app to login & it has failed to do so?

Good day! Just this afternoon, I started experiencing some strange behavior in my browser. Google asks me to solve a captcha every 15 minutes, and when I access services like YouTube Music or even Google Calendar, it asks me to enter my browser master password (I have it enabled), even though my Google account password isn't there.

I've updated my IP address three times, and everything works fine on another PC on the same network, as well as on my phone with the same browser.

The window doesn't always appear, but usually two or three times at a time.

I've also noticed a pattern: for example, on YouTube Music, video previews don't load until the window is closed.

I don't know what the issue might be, but updating to the latest version didn't help. This problem practically prevents me from using the browser. What should I do?

Enhanced Tracking Protection is stopping me from accessing many websites which, on other browsers including Firefox for Android, have nothing wrong with them - UK Met Office, forums, webcomics, Patreon... In many places, it's stopping me from connecting to the website altogether, or even logging into desktop app services when I have to use a browser link to log in; the login process simply doesn't resolve. I've tried disabling and removing extensions, changing settings, refreshing the browser and clearing the startup cache, but nothing seems to help. I cannot work out what's wrong, and I cannot disable Enhanced Tracking Protection. I'm having to send this message via TOR browser, because on Firefox, the Mozilla Support site is reduced to just text and links, with no frames or images, and barely navigable. This also means I can't pull Troubleshooting data direct from my Firefox browser for this form, because the form page's display is also broken on Firefox; I may be able to provide troubleshooting data on request, but I will require step-by-step guidance.

I don't know what to do, and I need help.

Firefox is updating 2-4 x/month while in use and has to be restarted. But my setting is on "Check for updates, but choose when to install". The last update recorded is listed as February 2026. So what gives? Thanks

Hello, I noticed that when browsing webpages in Firefox, a window periodically appears asking me to confirm a certificate, presumably from a website (roughly called lt3.google). I haven't downloaded anything malicious and I regularly scan my system with an antivirus. Please help and respond. Thanks in advance.

I am writing to report a recurring technical issue that began appearing today across multiple devices.

When attempting to access Google websites (specifically Gmail and Google News) using the Firefox browser, users are being prompted to identify themselves via a security certificate. Previously, this authentication step did not occur, and access was seamless.

Key Observations:

Impact: We have confirmed this behavior on three firm-issued computers as well as one personal device.

Browser: The issue is isolated to Firefox; other browsers appear unaffected.

Timing: This behavior was not present yesterday; it started manifesting today.

We suspect this may be related to a recent network configuration change, a new security policy rollout, or a browser update that has altered how Firefox handles trusted connections to Google services.

Could you please inform me whether there have been any recent changes to our SSL inspection proxies, root certificate stores, or DNS configurations? Additionally, does anyone else on the team have visibility into a widespread incident affecting Google certificates, or should we proceed with troubleshooting individual profiles?

I have always been able to click on a box in the upper right to see my bookmarks on the left side of the screen.

This has now disappeared and the only way I can see the bookmarks is to go to "manage bookmarks". I don't see how to bring it back to the way it was.

I didn't knowingly change anything.

Thank you

One Win 10 laptop has Firefox 151.0.4 64bit and I've got the Firefox VPN working on it. My other Win 10 laptop has Firefox 152.0 32bit for some reason, and I've logged on Mozilla but all I can find in VPN requires payment. I don't understand the diff that the higher version is 32bit and I can't find the FREE VPN . What should I do?

Morning, I dont know why but before i reset my pc i had a sport widget with all the other widgets, but after the reset i redownloaded firefox and got back all the widgets exept the sport one, any way i can fix this issue please? Thx in advance

I'm trying to use the built in VPN. I'm signed in but it just keeps returning me to the same page. The VPN icon doesn't have a green tick - it keeps the little black cross next to it. What am I doing wrong?
