Windows 10, Firefox 131, Thunderbird 91.13 I set Firefox as default browser - I can't open links from Thunderbird in Firefox. I set Chrome as default browser - I can open links from Thundebird in Chrome. How can I fix or debug this?

I have cleared data and cache and the time is correct but I get, Error Code: PR_CONNECT_RESET_ERROR, and will not log in. I have also done a cold, and hot restarts.

the login never completes and there are messages at the bottom of the screen that it is waiting for various sites like ips.navigatorixa mail.com if I wait Firefox eventually times out with site not responding

Hi,

I have been struggling for months and months with Firefox on macOS. I have been the only user in our company struggling.

Our IT has been constantly attacking me for using Apple macOS Betas and iOS Betas. And many people in the company have assumed the problems are related to macOS DNS issues.

To try to solve the problems, we removed my Fortigate hardware vpn. We set me up with a new wifi router.

I am on macOS 27 Developer Beta 5.

Brave can access process.tomsawyer.com and build.tomsawyer.com. Chrome can access process.tomsawyer.com and build.tomsawyer.com. Safari could not access process.tomsawyer.com and build.tomsawyer.com. Firefox could not access process.tomsawyer.com and build.tomsawyer.com.

I have been struggling for a long time. Today Safari was unable to access process.tomsawyer.com and build.tomsawyer.com, both of which are internal Tom Sawyer Software web sites. I finally realized that I had iCloud > Private Relay turned on and I decided to try turning it off.

Good news Safari could now access process.tomsawyer.com and build.tomsawyer.com.

I went about my business trying to debug other problems because Firefox on Windows 11 also could not access process.tomsawyer.com and build.tomsawyer.com. I have a brand new Windows 11 setup on another laptop. Turning off DNS over HTTP in Firefox on Windows 11 solved the problem so now the Edge, Chrome, Brave, and Firefox browsers could all access our internal Tom Sawyer websites, good news!

Then at the last minute, because I became curious, I did a test and I turned off iCloud > Private Relay and Firefox suddenly could access process.tomsawyer.com and build.tomsawyer.com on macOS.

I then turned on iCloud > Private Relay and Firefox suddenly could not access process.tomsawyer.com and build.tomsawyer.com on macOS.

I quit and restarted Firefox in between each change of settings for iCloud > Private Relay.

I did this Private Relay on and off a couple of more times, yes turning it on breaks Firefox on macOS when accessing internal company websites.

This reminds me of the old days where Windows and Internet Explorer were intertwined. Apple is doing something similar to what Microsoft used to do in the bad old days with Internet Explorer.

I've been literally struggling for months and months, and now I use Brave happily. I'll hope my Firefox problems are now solved but the Firefox team should work with Apple and address this iCloud > Private Relay problem together.

Good luck!

Thanks, Brendan Madden CEO Tom Sawyer Software

Hi everyone,

Since updating to Firefox 129 on Windows 11, some tabs become unresponsive after my laptop wakes from sleep — no crash, no "Not Responding" warning, just frozen. about:processes shows the tab still running with ~0% CPU, so it's not hung, just not repainting.

Tried: disabling hardware acceleration (helps a bit), fresh profile (still happens), Troubleshoot Mode (less frequent but not gone).

Anyone else seeing this? Known WebRender/compositor bug tied to sleep/resume, or a Windows 11 power management conflict?

Thanks!

Firstly I have lost my default,. I had it set up as google . next I lost all my bookmarks, I have also lost the bar I had which included bookmarks history etc. this all happened in the middle of using a program and now I cannot get it back. PLEASE TELL ME WHAT IS HAPPENING

I would like to link firefox with wild tangent games. Right now my games are not launching and I was wondering if it's because I changed browser from chrome to firefox?

Hello. When I open a new tab page, all 6 panels below keep scrolling right like their not loading correctly. I have tried everything to make this go away since it is very distracting. Any ideas of how to fix?

On my Firefox Home Page, I selected two rows of PINNED shortcuts. Each time I open a webpage that webpage is added not only to the two selected rows of shortcuts, but "keeps" EVERY webpage selected after filling the two selected shortcut rows. It is not only annoying and inconvenient, but s l o w s work time to a crawl around these shortcuts ... few, if any, are helpful. If I want to re-entry an UNPINNED shortcuts, I go to history and select the one I want. WHEN is Fire Fox to solve this seemingly simple but annoying problem?
