For the past few days hot links in Thunderbird do not open in Firefox. Selecting a link in an email opens or brings to the fore a copy of Firefox with the link address and the wait icon but nothing else happens. I have to close Firefox, copy the link location, Past and Go in Firefox, and then the linked page appears. This behavior happens even in Troubleshoot Mode, so it is not any plugin or customization. I am also running Mozilla VPN. With VPN disabled, hot links in Thunderbird open in Firefox as expected. Now you know where to look.

Also, when I tried to add Troubleshooting Information below, nothing appeared. When I selected to option to be shown what to do, this page was replaced with other which deleted all this text, and now I am entering it all in again, which is severely frustrating. On a page where the user has entered possibly a volume of information, there should not be any sloppy risk of deleting that information due to page mishandling. Open help or assistance information in a separate tab, please. Think ahead about this stuff. You are supposed to be web design experts. Instead your web site spits in my face just when I am asking for help. Think. Plus, I had to get the Troubleshoot information manually so that is not being as automatic as it appears to be , either. Getting help should ideally be a button click, not jumping through hoops.

Hello!

I use a VPN when I access the web and I recently updated my OS (Mac OS Tahoe). I updated Firefox and now DNS over HTTPS (DoH) is enabled in Firefox. When I have my VPN enabled, I cannot access the web, there is some problem with DNS resolution. I have changed my Firefox DoH settings to Standard (I have also used Strict) and have typically been unable to resolve web URLs correctly. There have been a few times that I have been able to use 'Standard' DoH strictness / settings and also use the VPN successfully at the same time, but typically when I have the VPN enabled Firefox cannot access whichever 'mozilla.cloudflare' address it is attempting to use for DNS resolution.

The VPN vendor suggested always using the VPN's DNS resolver. I have done this and I still have the same problem. What should I do to ensure that I have secure DNS and can successfully use a VPN?

Thank you.

I recently updated to Firefox 135.0 on MacBook Pro, Catalina, OS 10.15.7 In the past, with multiple Firefox windows open & multiple tabs open in each, when restarting, "reopen pages on startup" selected, system loaded & ready to go, I'd find all windows, tabs & history available upon launching Firefox. Since update to 135.0, shut down & restart, launch Firefox and I find a single blank new window, no multiple windows, no tabs, no history. I've tried to find [Settings] to make everything come back - no joy, to no avail. Suggestions? Help? Thanks, JS

I am trying to set up a vpn using Proton as a Firefox add-in but Firefox won't let me use it, saying it has invalid credentials. I can't contact Proton because if I enable it as an add-in to Firefox, I can't use my browser. Do you know of any other vpn networks that work securely with Firefox?

I have be using Firefox Browser with Norton VPN turned on for a few years now without any problems. I was browsing and got connected to a website, then ever since Firefox stops working when Norton VPN is turned on. I tried uninstalling Firefox completely using software, and reinstalled Firefox it, with no success. The Virus scans are clean. I have a dual boot of Windows 10 and 11. I use Windows 10 the most. I changed to Windows 11 and had no problems with Firefox until I imported bookmarks from Windows 10's Firefox.

8 out of 10 times that i try to connect to the following site:

https://www.tax.ny.gov/online/

I get the following error message:

Secure Connection Failed

An error occurred during a connection to otc.tax.ny.gov. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

Now and then, I'm able to log in successfully. lately though, I'm having trouble logging in using Firefox browser.

This is becoming very frustrating. What could be the issue? What do i need to do to resolve the problem?

Firefox is locked by this:"Your browser is being managed by your organization." I have No Organisation. I am a private user! How do I unlock it? as nothing seems work!

My personal computer's Firefox says the browser is controlled by enterprise. I have no enterprise.

How does this Enterprise policy get set? And how can I remove it?

I'm receiving this message The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

Hello,

Recently I have noticed 'Your browser is being managed by your organization. - That being ImportEnterpriseRoots' appearing in settings. I have seen this mentioned by others but as of yet I cannot see if it has been sorted yet. I have uninstalled and it went away, but it has since returned the following day. I Do not have any other anti-virus on this laptop other than Windows Defender so it cannot be that. I will not be using Firefox as default until this is gone, or at the very least know that its safe.

I'm trying to configure Firefox on Mac using our MDM. The goal is ultimately to control a bunch of settings, but I'm trying to start simple by just installing the 1Password extension.

When I deploy this .mobileconfig file, nothing seems to happen to Firefox. I made this by following the example at https://github.com/mozilla/policy-templates/blob/master/mac/org.mozilla.firefox.plist but it doesn't seem to work and I am not sure how to debug.

After accidentally closing firefox I could not restore my last session after going to. history because the restotre tab was not there. Only recently closed tabs and recently closed windows and search history was there. I also had the box sent in setting to restore last session but it did not do that either. Am I missing something. Sorting through all the history would take quite a bit of time. I am on a macbook with sequoia ios.

Thanks

I have over 100 open tabs spread over 4 Mac desktops. I can no longer access ANY of them after upgrading to macOS Tahoe 26 and installing ESET Cyber Security Pro. I've used ESET with Firefox for many years without ANY problems. But now I have to choose between uninstalling ESET and being unprotected in order to use Firefox AT ALL. Every single webpage is blacked out with the message below. ESET support says that Firefox needs to issue an update to fix this problem.

You are fools. With the new desktop version you destroyed all my settings, all the sites I have remembered for years, without asking me if I wanted it because you turn off all my extension. You shameless idiots, you have destroyed all my years of work. And now I have an empty Firefox. Since it is empty, I will never work with you again, because I do not know what you fools can do, and you do not even ask me. I will switch to a new, smarter browser.
