Upgrading to firefox 28 caused too many issues with Flash compatibility so I attempted to go up to 29 - there are TOO many changes that require WAY too many addons to correct all the things that were changed (in other words, I hate everything about firefox 29 - every last change is horrible to me and I refuse to use it)
I have happily used firefox 25 for quite a few months have installed it - and a large FEBE backup of settings and addons onto myself and countless customer pc's over the past few months. The question was not answered and I require the same information.
