Today’s screenshots at https://github.com/mozilla/testpilot-containers/issues/771#issuecomment-328325416 showed four extensions that can not function without consuming space. Those shots were somewhat contrived; I began with a clean profile.
Realistically: I forgot that with my everyday profile, I already use at least two more.
Six in this shot:
Shortlist below.
Any others? (I’ll add to the list.)
https://addons.mozilla.org/addon/enable-rightclick-and-copy/
https://addons.mozilla.org/addon/jxl-page-translator/
https://addons.mozilla.org/addon/taborama/
(Only one of the two icons for Taborama is movable. The other, which overrides containment, is immovable.)
It’s remarkable that all of them are modern (only one, Mozilla’s, is not yet compatible with Firefox 57).
Is there something about WebExtensions APIs that inadvertently over-encourages consumption of space from the location field?
It troubles me that these things are immovable. No overflow …

Three of the originally shortlisted extensions were fixed on the day of this topic, see https://discourse.mozilla.org/t/-/19044/4 below.
