Bugzilla Nightly I
might need a forced refresh to get rid of icons?
Today's nightly. Win7.
112.0a1
Build ID 20230215093902
Something screwy going on.
With mozilla.org blocked, you shouldn't get icons.
URL:
viewtopic.php?t=26928
URL:
https://bugzilla.mozilla.org/home
URL:
https://bugzilla.mozilla.org/show_bug.cgi?id=1800742
You may or may not when you open URL.
Regardless.
Allow mozilla.org
Icons should display
Forbid mozilla.org
Icons still display - but should not
Force refresh the page
- Icons then do not display, as expected

102.4.0esr & 11.4.11rc2
& I'm seeing the same thing!
So I guess it is me?
(No such issues in NoScript Classic.)

It seems a behavior we've already
discussed here, but in the end that was an actual Tor Browser specific bug.
Web fonts are aggressively cached by browsers.
In Firefox you can disable the cache (and see the block taking effect immediately, instead than after a forced refresh) by setting the
gfx.downloadable_fonts.disable_cache preference to
true.
