User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:84.0) Gecko/20100101 Firefox/84.0

Steps to reproduce:

1. Installed Firefox Nightly.

2. Tried to sync accessibility settings from Firefox.

Actual results:

Not all accessibility/safety settings were synced, leaving Nightly unusable.

I have trouble searching about:preferences because the cursor is firing. It hurts. It seems that sync has copied my settings to disable autoscroll and smooth scrolling.

I can't read about:config because the cursor is firing, but I know that ui.caretBlinkTime 0 was not copied from my existing installation because the cursor is firing. I can't check autoplay settings or other accessibility/safety settings using about:config.

Expected results:

Accessibility/safety settings should be synced. At least those in about:preferences and about:config.
