I've put Quantum on my Lubuntu box but cant open it as it gives a parsing error, XML Parsing Error: Undefined Entity location: Chrome:// Browser/content/Browser.xul line number 1165, column 7:
Sorted it, uninstalled it, removed the PPA, then installed the normal firefox and upgraded it. Its running OK now, its quick but looks a bit tonka toyish.
I've now got it running on my tablet and phone as well as my PC. I've had it running for a few days now and its been OK, its quick and I've not had any problems with it, the only thing I've noticed is a bit of flickering when scrolling.
