Hmm, it loads pretty quickly in Chrome-on-Desktop for me. (in normal mode and in their RDM mode)

It also loads quickly in Firefox-Nightly-on-Destop (even with content blocking disabled).

The key place where I'm seeing a difference is:
 - Firefox on Android (with no content blocking), which takes 4-5 seconds for our blue loading bar to stop animating on load & reload.
...vs:
 - Chrome on Android, which takes 1-3 seconds for its blue loading bar to stop animating on load & reload.

Aside from getting content blocking enabled, I think most actionable thing we can do here would be to discover if there's a particular operation (whether in querySelector runtime, or something else) where Chrome is beating us perf-wise, and then see what we can do about closing that gap.

Aside from getting content blocking enabled, I think most actionable thing we can do here would be to discover if there's a particular operation during the pageload here (whether in querySelector runtime, or something else) where Chrome is beating us perf-wise, and then see what we can do about closing that gap.
