I use Mull as daily browser but I felt it was much slower than Firefox and Fennec because it is very much hardened. I want to make Fennec better than stock Firefox but not as hardened as Mull but couldn’t find any wiki or guide for mobile version about:config. I was wondering if there is any guide for about:config which keeps track of mobile config changes too?
Complete unfounded speculation on my part:
I honestly wouldn’t be surprised if any observed performance differences were some weird placebo.
I know of no change that Mull makes that actually has any noticeable impact on performance.
And I’ve found Mull actually much smoother than Chromium-based browsers on my old Galaxy Nexus in testing.
