Hello,

I'm using Thunderbird portable beta version, for some reason.

MyPhoneExplorer can't synchronize with Thunderbird portable, I found, it's probably because the addon / extension is outdated.

I can't go back to non-beta version of Thunderbird, because I'd have to create a new profile and setup everything, I don't have time and don't even know how to do it.

Is it possible to release the extension which is working with the current beta version of Thunderbird, please?

Or any workaround? Change the version number in some file, so it will be working, please?

- MyPhoneExplorer 2.2 portable
- Thunderbird portable beta 143.0b3 (64-bit)
- Windows 10
- Thunderbird Addon MyPhoneExplorer - Version 4.8 Released July 31, 2025 27.7 KiB Works with Thunderbird 78.0 - 142.*
- This add-on is not compatible with your version of Thunderbird.

The beta versions are not supported by MPE by default.
