back navigation arrow doesn't work anymore, also not getting suggestoins when I start typing a URL... how can these be fixed?
So after I deleted a bunch of files/applications today (computer was threatening to crash), Firefox started to do a couple weird things. Navigating backward is no longer possible; the back navigation arrow is greyed out. Also, when I start typing a URL, it no longer suggests the rest of it, either in the URL bar itself or in a drop down menu (it used to do both). 16.0.2 is the current version, right? That's the one I kept, I deleted the others. Recently, I got the announcement that Apple isn't supporting my operating system, Mac OS X 10.5.8 anymore, I don't know if that is relevant. How can these things be fixed?
