I am having trouble with time-outs in my AT&T e-mail account, which uses Yahoo as the e-mail provider. Ordinarily, I have the Firefox Multi-Account Containers extension and the U Block Origins extension enabled. But, I have gone into Trouble Shooting Mode to see if I can avoid the timeouts.
Trouble Shooting Mode disables extensions. You can see that they are disabled.
However, even with extensions disabled, the Multi-Account Containers extension is still working.
How can this be? I want to have all of the extensions disabled to see if the AT&T time outs stop.
