Problems with versions 3.2.4 and 3.2.8 on Thunderbird 91

[NannoSilver]

The version 3.2.4 is not working properly on Thunderbird 91.3.2 x64 for Windows. The XNote++ button is greyed.

I manually installed the version 3.2.8 https://github.com/xnotepp/xnote/releases/tag/v3.2.8 that works fine, however seems it is labeled, internally, as version 3.2 (instead of 3.2.8), and, because of that, Thunderbird keep automatically downgrading it to version 3.2.4, that Thunderbird thinks is newer.

Thank you for the good job developing and keeping this very useful addon.
