[Pkg-mozext-maintainers] Bug#971734: webext-ublock-origin-firefox: after startup, doesn't work until disabled and reenabled

Package: webext-ublock-origin-firefox
Version: 1.33.0+dfsg-1

I have a similar issue.  But it seems to affect YouTube only.

See,  I have firefox-esr configured to launch and restore the previous session.
The example would be a single YouTube tab, with a video.  It get's restored,
but, ads will get reproduced, if autoplay is enabled of course. If autoplay is
disabled, the ad will sit there waiting to be reproduced, so you can skip it,
and it redirects you to your video, how it would be without uBlock. Except that
uBlock is enabled.
This get's corrected with a simple tab reload (F5).
If the tab is YouTube's homepage (no video), you can catch the first
recommended video to be an ad,  but it will go away in a instant without having
to reload the tab.

I have the defaults on everything (except for pocket disabled), I haven't
touched much my about:config (i can share my user.js, but IME it can be
reproduced with the defaults of a fresh install).
uBlock rules are also up to date.




My other extensions are privacy-badger and https-everywhere.
I already tried disabling everything but uBlock, and it's still the same.
If not clear enough I can try recording my screen in a short and lightweight
clip.
