I have been a happy Thunderbird user for many years. Currently I am trying to migrate my three Earthlink e-mail profiles from an iMac (late 2013) running macOS Catalina, to a Mac Studio (2022) running macOS Monterey. My Thunderbird profiles use POP for incoming mail. I have always preferred to store my e-mail on my computer, not on a server, and that's still my preference. I have a lot of history in my Thunderbird folders, and I don't want to lose all the e-mail I have stored in them. So I'm afraid to try to switch to IMAP, even if I wanted to, which I really don't.
On my old iMac, Thunderbird is on version 102.3, and it looks great! So on my new Mac Studio, after downloading Thunderbird 102.3 but not opening it, I set up Profile Manager using Terminal (in Finder/Applications/Utilities), and created my three profiles exactly as they are on the old machine. Then, on the old iMac, I went to Library (via Finder) and copied my three profiles to a flash drive. I connected the flash drive to the new Mac Studio, where I copied and pasted the contents of each old profile into their corresponding new profiles. So the new profiles have new names, but the contents have been replaced by my data from my old Thunderbird profiles. This is the standard procedure, and I was very careful to do each step correctly.
Well, everything is there all right, but sadly, it is all so unbelievably tiny that it is impossible to read or use. I experimented with Zoom and Font Sizes in the View menu in my Thunderbird profiles, but the results were still very unsatisfactory, and the changes refused to persist in individual e-mails. The whole Thunderbird installation looks like it doesn't fit properly on the Mac Studio, and I can't figure out how to make it bigger. I went to Settings in a Thunderbird profile and tried increasing the font size under General->Language & Appearance, but this had no effect at all. I have also made sure that my Display settings on the new Mac Studio match my Display settings on the old iMac, but this doesn't make any difference to Thunderbird either.
I can't understand why version 102.3 looks so perfect with my three profiles on my old iMac, where everything is large and readable and fits properly, but not on my new Mac Studio! Obviously my profiles are compatible with the latest Thunderbird version, since they work fine on the iMac.
Oh, and by the way, BEFORE doing all of the above, I had initially used Apple Migration Assistant, which worked great for all my Apple content, but NOT for Thunderbird. So I uninstalled Thunderbird and deleted its profiles on the new Mac Studio, and started over again with a new install, as described above. Sadly, the results were exactly the same in both cases, whether I used Migration Assistant or downloaded a clean install of Thunderbird and manually transferred my profiles. Either way, the appearance of Thunderbird with my three profiles on my new Mac Studio is practically microscopic.
Does anyone understand what is going on? Can anyone tell me how to fix my Thunderbird? Or can you tell me what I have done wrong? I have always loved Thunderbird, and I'm brokenhearted!
