I am suffering issues only with the Google Search Fixer with android. It hangs quite often and I have to close the entire tab and open a new tab to search on Google. I have this happening on my phone and tablet
I hope this is somehow resolved by Google or if there is a fix somehow.
It cannot come to iOS until Apple allows Gecko to come over. It may happen eventually if Apple ever loosens up more on what engine is allowed besides Safari.
I can't see it helping much unfortunately in bringing more over, since Firefox desktop isn't that big either.
Firefox on Android would be perfect for me, if I could ever figure out why Firefox randomly freezes using the Google search fixer addon from time to time, and if Firefox would ever get tablet support (tabs).
