ALL OF A SUDDEN I CAN'T LOAD THUNDERBIRD. IT IS TRYING TO LOAD, BUT IT IS SO SLOW THAT IT CAN'T AND TIES/LOCKS UP MY MACHINE. I HAVE AN XP MACHINE.

I JUST DOWNLOADED AND UPDATE, AND IT MAY ASSUME I'M USING A NEWER OPERATING SYSTEM THAN XP. I TRIED TO DOWN LOAD AND REINSTALL THUNDERBIRD, BUT IT WOULDN'T DO IT, RAN UNBELIEVABLY SLOW (TRIED ALL NIGHT AND NO DOWNLOAD). I THINK I MAY NEED TO DOWNLOAD AN OLDER VERSION TO RUN ON XP. WOULD THAT FIX IT?

Start *Windows'* safe mode with networking enabled - win10 https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode - win8 https://support.microsoft.com/en-us/help/17076/windows-8-startup-settings-safe-mode - win7 https://support.microsoft.com/en-us/help/17419/windows-7-advanced-startup-options-safe-mode#start-computer-safe-mode=windows-7 - XP https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/boot_failsafe.mspx

Still In Windows safe mode, start thunderbird in safe mode - https://support.mozilla.org/kb/safe-mode-thunderbird

Does problem go away?

i was able to open thunderbird, but i wasn't connected to the modem and couldn't send or receive emails. i closed and restarted normally but thunderbird still locked up everything and didn't open, same problem as before.
