Problem with extensions after upgrade..
So, I had some problems because the default setting on firefox was set to automatically have it attempt to upgrade itself. After clicking no again and again (yeah, I know I should've turned off the setting but my net time was limited, and I had to get to work) I accidentally clicked yes which caused firefox to attempt to upgrade itself prior to every startup..
Well, that got old real quick, so I decided to attempt to follow the upgrade instructions on the site. Seemed like everything worked out OK, but when I booted into firefox (I presume there was a problem with one of the extensions I was using) it gave me a big error window which I couldn't get past..
