I have Thunderbird setup handle gmail accounts on this computer and 4 others. But Thunderbird won't connect to Gmail. Keeps telling me I have the wrong username or password. The same addresses and passwords work on the other four computers. The only way I can access my accounts is using Evolution. It works okay, but not as good as Thunderbird. So I purged Thunderbird and installed the SNAP version. Same thing happens. 1)When I sign up for the account I put in my name email address and password. 2)Thunderbird says it has found my account and then prompts me to include my calendar and contact. So I push the button to include, but a webpage appears in a popup. 3) It prompts me to login to my google account. I do 4) Then it prompts me to allow Thunderbird to use my mail, contacts, etc. I do. 6) Then a window opens on my computer prompting me to download a file. I tried it 3 times. The file names are 6TyeTgAZ, 6TyeTgAZ and tqEoDQlb. I opened them with a text editor. They are empty files Thanks in advance for any assistance you can provide. Regards, Steve MacLellan
