Since I installed that new version, Thunderbird has been slow and stops running frequently.

Does the same thing happen if you

Thank you for getting back to me and sorry for the delay in responding. It happened that my computer crashed and I had to reinstall everything. Apparently things work now.

I have Thunderbird Supernova 115.5.2 64bit, and it is incredibly slow, both receiving emails, and moving to folders.

It never used to run as slowly, can anything be done to make the programme run more quickly?
