I updated Thunderbird yesterday, and the program is a disaster now. Parts of toolbars are missing or are totally relocated. Functions are not working properly; e.g, I can't filter by field, and when I try to type in the filter field, the letters are not coming out correctly as I type them in. I can use tags, although the "tag" function is not properly located, but when I select a tag, the tag the color I assigned to it doesn't show when I go back to the inbox. I am using Windows 11 Home Version, which I updated right before the Thunderbird update; everything else is fine. Is there a way I can get back to the old version, and if so, will I have to wipe everything out and start over? The last time I did this there were numerous problems and I had to pay my computer guy close to $1000.00 to fix them; even then, some problems remained. Thank you!
