For several months Thunderbird has random events of being very very very slow (win10)

more options

Most of the time Thunderbird is very slow, taking minutes to log in, minutes to download tiny messages, but sometimes is quick. Sometimes Thunderbird complains the password is wrong, but after three retries it accepts the password. Only occasionally it is quick as I'd expect. This has been happening for several months. I had hopes Thunderbird would find and fix the issue without challenge, but as the issue continues I am now raising it formally.

Please start Windows in safe mode with networking enabled - https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode

Does the behavior change?

This is not a practical test for this issue. The reason is sometimes Thunderbird works okay. The computer would have to be started in safe mode day after day for ten days or more to draw a statistically significant conclusion. Please find another way to move toward a diagnosis.

Had to ask the web what you are talking about. You did not say "Thunderbird Settings". System Integration, no boxes checked.
