Spent from Weds morning until Thursday morning trying to element a glaring flaw! Simply put if I install the new fire fox which identifies as firefox+1 Uma Firefox goes to sh**. becomes semi-transparent so everything is garbled. What took so long was having to use my back up drive to restore a half dozen times. Conclusion: If you don't install the new Firefox, everything else is mint solid. And the existing Firefox works fine. I would diffidently advice against installing the new firefox for Uma unless you have a good recent backup or you can figure out how to straighten Uma Firefox out. Oh! I had trouble accessing this up date or even seeing it in Update manager; kept telling me that I had no internet connection. What I had to do was change my repository download sites. Just keep tying them until you find one that works. I "think" that many repositories may have yet to update, but that's just a guess. BTW this was an update not a fresh install..
