Some versions of FF have trouble with pdf files.

I use keyscrambler. It won’t work with later editions. The new version of keyscrambler scrambled my computer, so I had to revert to an older version.

Several extension developers quit developing their extensions, because they couldn’t keep up with the rapid releases.

My main version of FF is 15. I just quit updating extensions and FF.

And there is the ongoing problems between Adobe Flash and FF since about version FF 12 or so.

I'm about ready to go back to FF15 myself. I'm tired of all the changes Mozilla is making to FF and though I still use it, it's been getting really buggy lately.

BTW, what is keyscrambler?
