Just got around to migrating from WLM to Thunderbird and I'm getting my email accounts [Gmail] added to my Thunderbird [Ver 68.8.1] installation on my Windows Home 10 laptop. First one went fine and in the process was presented the 'Sign In with your Google Account' prompt screen. Email account name was automatically populated and after selecting 'Next' all I needed to do was to enter my Google password. Account installed fine and Thunderbird/Google did their 'hand-shake' and my emails were downloaded into Thunderbird. Off to a good start! Looking from the Google Account side of things, it showed 'Mozilla Thunderbird Email' under 'Third-party apps with account access.' So I considered this one done... Getting my subsequent Gmail account added didn't go so well as I couldn't get past the 'Sign In with your Google Account' prompt screen. The Email account name was auto-populated as before, but selecting 'Next' didn't get me to what should have been the enter password screen. It simply 'cleared' the account name and sat there. Trying to enter the account name manually didn't get me anywhere. This occurred for the couple of the Gmail accounts I tried and they all were 'fine' using WLM and/or Web access to the respective Google accounts. In looking thru the Forum I see similar issues with earlier builds. Appreciate any comments/suggestions. Mark
