1. How to move mail between two different Macbooks with different OSX and different versions of Thunderbirds?

How do I move my email profiles (there are several) from an old Mac to a new one, when the old Mac can't be upgraded anymore and the Thunderbird versions don't match?

Old Macbook OSX Monteray 12.7.4 can not go any higher on OSX due to hardware not being compatible Thunderbird 140.5 Oesr 64 bit - don't know if it can be updated or not, but expect not. Minimizing run time as much as I can because the fan is going nuts and I think the battery is going - gets very hot.

I copied all the different profile folders from the Old Mac to an external drive. However, I don't think I can just plop them in to the new Profiles folder on the New Mac, given the Thunderbird versions and OSX version don't match.

New Macbook OSX Sonoma 14.1 Thunderbird 153.0.2 aarch64 Not updating to Tahoe yet because then I can't use my 2019 MS Office products - need to save up to update those first

All I need is e-mail - not calendars, contacts etc., although it might be nice to to have those Thanks in advance

2. How to .pdf old emails (With attachments) Also, the profiles folder is huge (219 GB), with multiple profiles and I want to save old emails (with attachments) into .pdf and appreciate advice on what .pdf converter/file converter would be best. It doesn't have to be free. It does need to respect my privacy.

Both Mozilla products spontaneusly disappeared from my computer. Firefox requested a reinstall, and all was recovered. Firefox completely disappeared, and I had to restore from backups. I am seriously worried. What is going on?

Dear Mozilla team, I have nothing to add I made a short summery to a guy who asked why his computer starts redumdebly with Gmail and it's specially to him my question is adressed to.

Completely broken AI and absolutely nowhere to download it.... Worked perfectly fine yesterday, and the poof, it's gone. All the options are still there for AI block and not blocked. Configs are set. You can even see where the AI is supposed to be. Where is it????? Why is there nowhere to download this "extension" (SmolLM2-360M-Instruct-GGUF) when Firefox gets its back broken? I'm not 500 IQ, so I'm not compiling it myself on Linux. Please help me get this feature back. I'm trying to give as much information as I can, but I know it's probably gonna fall short. browser.ml.chat.enabled = true browser.ml.chat.page = true browser.ml.chat.menu = true A bunch of Nimbus experiment values are present. Firefox clearly still thinks the ML/chat feature exists. Yet the On-Device AI section is missing from about:addons.

I am a TD Bank customer who uses their Bill Pay feature. A recent FireFox update now prevents me from completing my payment sequence. Please alert me how this can be fixed. I like the FireFox browser but will remove it from my computer if no fix is offered. When I use Google Crome I have no problem completing my payment sequence. Thank you.
