OT: Thunderbird and gmail

[Kenneth Brody]

Last week, Google apparently made some changes in gmail which prevents you 
from logging in to two different gmail accounts at the same time.  (I had 
two tabs open in Firefox -- one for each of my gmail accounts.)  Until last 
week, everything worked fine.  Then, as soon as I logged in to one of my 
accounts in one of the tabs, the other tab would be logged out. 
Fortunately, it was a simple matter of closing the second tab, and then "add 
account" to add the other account into the first tab, which now goes back to 
the old behavior of having two tabs, one in each account.

Unfortunately, I have not found a solution for Thunderbird, which now gives 
the following error on one of my accounts:

     Sending of password for user kenbrody did not succeed. Mail server
     pop.gmail.com responded: Web login required:
     https://support.google.com/mail/bin/answer.py?answer=78754

I have tried everything suggested in the given URL, but to no avail.  It is 
always the same gmail account which fails, and the other account always 
succeeds.

I have even tried exiting Thunderbird, waiting overnight, starting 
Thunderbird, and trying the failing account first, again to no avail.  The 
other account succeeds, and this one fails.

Note that POP still works on that account, as my iPod is attached to that 
account, and it still works just fine.  It's apparently just Thunderbird 
that's failing.

Has anyone else run into this?  Any suggestions?
