I'm slowly persuading my wife to move over from outlook to Thunderbird (due to constant issues with google sync). I've got it all setup nicely and working BUT i'm having a real issue with the thunderbird calendar taking an absolute age to populate It is quite a well used calendar with lots of recurring events/reminders to pay bills etc. Just to get the Holidays in United Kingdom takes about 30 seconds and to populate from the gmail calendar takes around 8 minutes

It's the one stumbling block i'm finding to persuade her to move over so any advice that can be given would be greatly appreciate

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

There's a well known "window-focus bug" in MacOS 26, where clicking on a window (even the title bar) doesn’t bring that app to the front. It seems like Thunderbird is particularly susceptible to this bug, and I was kind of tolerating it in 26.1. But just today I updated to 26.2, and oddly this has made the problem worse. Is anybody else seeing this and is anybody aware of a fix? Various MacOS discussion groups recommend tweaking MacOS mission control settings, but I don't use mission control at all.

This version is very slow when opened ... it seaches through for various emails (gmail and Outlook) and snags on something called 'Checking Mail Server Capabilities'. Other issues include a slow copy to the Send folder once an email has been sent. I am not a technical person, been using TBird for many years and until now have really enjoyed its capabilities

Is there a known related issue? Overall the performance is very poor ... I use a series 7 processor and have WiFi speeds in excess of 100 MB.

Thanks Ron
