Rated 1 out of 5 stars

by hofmannm on March 27, 2025 ·

I've newly installed TB v136.0.1 (64-bit) on a new Windows 11 computer and can't get it to accept the add-on installation file (xpi). It keeps telling me that the file is corrupt. Is the add-on not compatible with this version of TB?

I'm trying to transfer email messages and an address book from the long-outdated Windows Live Mail. I've got the exports from WLM. I just need to know how to import them into TB (this is the first I've used TB, so I'm not familiar with it, but I'm usually pretty good at figuring stuff like this out).

I hate to give a rating of 1 star since I'm not able to install it and haven't really tried it out. I'll be happy to change my rating if someone can give me some guidance.

Sorry for the issues. I have not heard of both
a corruption and not compatible message on install.
The corruption issue happens when downloading from
Github, but that's just for betas. V14.1.6 was just
released on the Thunderbird addon site, however,
it was discovered that some users had a failure
in exporting messages that did not appear in my
test group.

I have stopped distributing v14.1.6 which is required
for v136 and should have v14.1.7 out shortly.

I have beta that everyone is reporting fixes the issues.
Can you post your issue in the github repository ehere
I can help you and get you the beta?
That would be great.
