Thunderbird Community Forum

I recently had a hardware crash on my fedora machine and transferred my thunderbird backup to my mac. I have a new fedora machine and want to transfer my thunderbird profile from the mac to the fedora machine. The problem is that Fedora is currently at version 128.12.0 and the mac is currently at version 141.0.

In response to a previous question https://support.mozilla.org/en-US/questions/1513367 I got a suggestion (which I have not been able to make work). 'if you Exit Thunderbird and access profile name folder, then delete the 'compatibility.ini' file, you should be able to use the profile on an older version.'

Here is the revelant directories on the mac

``` bradbell>ls Library/Thunderbird/Profiles y0mvyr8l.default

bradbell>cat Library/Thunderbird/profiles.ini [General] StartWithLastProfile=1

[Profile0] Name=default IsRelative=1 Path=Profiles/y0mvyr8l.default

bradbell>ls Library/Thunderbird/Profiles/y0mvyr8l.default/ | grep compatibility compatibility.ini ```

I think I should put y0mvyr8l.default in $HOME/.thunderbird but I am not sure what should I change ?

Very clear instructions. May I suggest an optional step, after discovering tens of thousands of WSDEML files that slow the copying of the profile to a crawl.

Yeah search integration can be useful but in my case it probably quadruples the copying time and maybe useless on the new machine.

Hi, When the big update happened with Thunderbird 115, I started having a ton of problems, which I posted about on this forum at that time. It seemed too complicated to resolve, so I've just been forcing TB to quit when I get the "Thunderbird is not responding" message. I've done that hundreds of times since November, 2023.

Now I want to use a newer computer and thought I would install the latest version of TB. I wonder if I have corrupted my profile by all the force quits. Should I create a new profile and just start from scratch?

I'm really hoping the current version doesn't have a ton of bugs and that I don't have to spend hours on this project.

Thanks, DD

Hi,

Just upgraded to 140.0.1 and when I restarted Thunderbird it asked that I create a new profile, as if it was the first time I used it. I checked in %APPDATA%/Thunderbird/Profiles, I have 2 folders, one ends with .default (47 b), the other one, ends with .default-release (around 7Gb). I've tried messing a bit with the profiles.ini and the install.ini files but it didn't change anything appart from creating other 47b folders when restarting Thunderbird. So I'm back to the original files but I'm stuck. When I open the about:profiles page, the .default-release one does appear at the top and seems to be the default one, yet nothing shows up in the usual window.

What should I do?

Thanks a lot
