Disable randomised Firefox HTTP cache decay user test groups
I need to look into it more, but I think we should be setting
-1 to disable HTTP_CACHE_MISS_HALFLIFE_EXPERIMENT. Since we have Telemetry disabled, of course, Mozilla's experiment shouldn't be collecting any data on our users. However, if that pref is not set in
-1, it will default to
0. And if it's
0, then it's randomised between
4 inclusive, setting different HTTP cache decay times for the four groups, which might make for a bit of a rough-edged fingerprinting mechanism.
