often the map does not appear until e.g. after clicking away from, then back to, the mapped page

Waterfox 56.0.1 on FreeBSD-CURRENT.

Reproducible with Minimap Scroller alone installed; reproducible with Firefox 56.0.2 (64-bit).

Mmm that's weird. We should get a redraw from either the onload event or the mutation events if things changed in the DOM. Can you check with:

• Other pages. Maybe it's specific to github somehow?
• Firefox Nightly, or at least 57+

Also look at the browser console (not the web dev console) looking for error messages - do that without any other extensions installed though, otherwise it's going to be super verbose.

Thanks for the speedy response!

Not specific to GitHub. Most pages seem to be bugged. Here, for example:

• https://bugzilla.mozilla.org/show_bug.cgi?id=1339561

Random guesses:

• gfx.xrender.enabled was true
• layout.css.servo.enabled was false (for compatibility with Scrollmap)

I switched each boolean, the issue persisted.

I'll test with a Firefox Quantum on Mac OS X 10.9.5 …

Not reproducible with Firefox 57.0.3 (64-bit) on the Mac.

Firefox 56.0.2 on FreeBSD-CURRENT: AFAICT, nothing relevant in the browser console when the bug bites at e.g. http://meatwad.mouf.net/rubick/poudriere/packages/

While creating services from category 'profile-after-change', service for entry 'Notification Telemetry Service', contract ID '@mozilla.org/notificationTelemetryService;1' does not implement nsIObserver.

– the first three lines appeared when Firefox started, the .ico-related stuff appeared when I loaded the page.
