Actual results:

I run into a number of bugs where pages load, Firefox paints them, then Firefox applies webextensions and repaits them, resulting in flashing and migraines.

e.g. https://github.com/new-xkit/XKit/issues/1969

Expected results:

I have set Firefox to delay painting, nglayout.initialpaint.delay 250 but that still paints before applying webextensions. An option which delays painting until after applying webextensions would remove even more flashing.

The Bugbug bot thinks this bug should belong to the 'Core::Web Painting' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.
