Just stmbled across this extension and installed it. However, it doesn't show up in the extension list. Is this because I've just moved to Tbird 3.0b3?
I'm also using TB 3.0beta3. TEBE resides at the top of my add-ons window and not alphabetically like my other extensions. I think this is because it is labeled (TEBE) with the parentheses. Did you look at the top of the add-ons list?
Weird. I initially saved mine to my desktop, renamed it from .zip to.xpi and installed it as normal. No issues at all. I'm on XP, what OS are you using?
Vista, but I suspect (with no actual technical basis for that suspicion) that there may be a clash with one of the many other extensions. I will try and delete a few that I don't use much and haven't been updated for a while.
