Hello. I'm using ThunderBird version 140.6.0esr (64-bit) in LiuxMint 22.2 (x86_64) kernel 6.8.0-90-generic.
I noticed that after some updates of Thunderbird that my Grammalecte add-on had disappeared from the menu-bar.
I re-installed Grammalecte(fr) version 2.1.1 from the Extensions library in the Add-ons Manager.
Now. when creating a new mail After I close the "Analyser" window, my cursor is invisible. I can't see the text insertion point anymore. No more blinking cursor. Although editing the the message is still ok.
Did I miss something when installing? Or is there a dependency problem in the build? (I don't code)
