Thank you so much! Wow, the only other thing I could find to open sqlite files requires QT -- an additional 1.3Gb download!!!
It wasn't obvious how to open a file. There's a new menu item in Firefox under File >> Web Developer >> Sqlite Manager. From there you click Database >> Connect Database. Also, there's a toolbar button you can use instead.
Sqlite Manager is great for finding out where your extensions are installed (open extensions.sqlite or addons.sqlite.)
It handles other file types too (db, csv, tsv) basically any kind of data table file that isn't locked.
