I was sorry to see that the 128 Nebula release did not fix the longstanding problem that Thunderbird is very slow to load in Sonoma, and has been since the Sonoma release. This is with 128.0.1esr (64-bit) on an Apple M1 Mac Mini with Sonoma 14.6. I have the same problem on a 2018 Mac Book Pro running Sonoma with an Intel chip. The problem is NOT manifest on a 2013 Mac Book Pro running the last release of Big Sur. In all 3 cases the same email accounts are loaded, so it is some interaction with the OS. (I previously reported this for Tbird 115 under Sonoma, with no resolution.)

Specifically, when I start Tbird 128 on the Sonoma M1 the window comes up in about 2 seconds but contents are blank. The contents don't fill until about 30 seconds. This makes it painful to quickly hop into email to do something, so I am resorting to Apple Mail when in a hurry. If I do the same on my 2013 Big Sur machine, it's 2 seconds for the window to come up and 8 seconds for the content to fill. Upgrading from 115 to 128 did not change this on any of the machines.

None of the enhancements of recent releases are of sufficient value to compensate for this, so I wish the team would focus on ensuring speed on all platforms. Is there any clue what is going on?

Until today it worked fine. But now whenever I try to login to Xfinity I get You don't have permission to access "http://login.xfinity.com/login" on this server. It works fine on Chrome and Edge. I have disabled my add-ons. I have cleared cache, cookies, etc. I have rebooted. I have turned off firewall. I have checked my DNS. I have changed the DNS protection to OFF in Firefox. I have checked my proxy setting (I have no proxy). I have reinstalled Firefox. Etc. Etc. Nothing works. The fact that it works on Chrome and Edge, that it has worked everyday until today gets me confused. I also tried using my mobile phone as a hot spot to make sure it wasn't related to my Internet connection or IP address. Anyone have any ideas?

Hello,

I have had this issue since at least 2022 starting with version 102.4.1. I am currently running 128.1.0esr on OS 14.6.1.

I figured I would post again, as it has been a few years and the previous posts are now archived, to see if any new solution options are known.

In short, Thunderbird runs perfectly fine in troubleshoot mode. When launched normally, it locks up as soon as it checks for new messages, I get the spinning beach ball, and I have to force quit to close it. Letting it sit for an extended time has no impact. Screenshot of status when it locks is attached.

If I start in Troubleshoot Mode it works normally. No problems at all. I don't appear to have any add-ons or extensions running, so I don't understand why this is fixing things. I've just been running it in troubleshoot mode for years now, which is fine, but annoying.

The only themes, extensions, or add-ons present are "light," "dark," and "system theme -auto." Nothing else.

I had read a previous post about disabling access to Contacts in System Preferences, I tried that, no luck. I also deleted all add-ons and extensions files, and folders. Folders were empty, no change.

Any other theories?
