Sure, having a little extra screen estate is nice, but I use the bar often, and the constant disappearing and reappearing gets on my nerves. Looked through about:config for any options that looked relevant and couldn't find anything. No luck turning up any documentation or add-ons that help either. Maybe my search foo is weak of late, or perhaps I'm the only one who thinks this is annoying.
Is there a fix for this besides switching to decaf and taking up meditation?
UPDATE: Sorry for wasting everyone's time here. A reinstall fixed the problem. Not sure how the copy I downloaded picked up that annoying behavior -- it was still present with all add-ons disabled -- but it's gone now. Thank you for making me aware that it wasn't normal Firefox behavior.
