Thunderbird Display Errors
I had a bit of a problem with Thunderbird under Windows this morning. I opened it up, and was greeted with a mostly-blank screen with no buttons to speak of:
Turns out my profile was referencing some Thunderbird extensions I had
mistakenly deleted. Instead of erroring out or giving me a warning, it
buggered itself up and just sat there confused. The references were in
C:\Documents and Settings\<username>\Application Data\Thunderbird\Profiles\<random>.default\chrome.
I happily deleted this entire directory and went on my merry way.
