Status: RESOLVED DUPLICATE of bug 1483591

(Toolkit :: Add-ons Manager, defect)

Description

[Mehmet]

Attachment: Snippet Tool Extension.mov

Nightly: 63.0a1 (2018-08-11) (64-Bit)
macOS 10.12.6 /10.13.6

STR:

1.) Run Nightly
2.) Visit any page
3.) Right click in the Snippet Tool icon in the Location Bar
4.) Select Manage Extensions

--> Snippet Tool Extension appears in the Manage Extensions section (but my own installed extensions are missing)

--> Disabling of the Snippet Tool Extension doesn't work

5.) Click on the Extensions Section on the left side

--> My own installed extensions appear, but the Snippet Tool Extension is now missing

Very weird :(

A screencast is attached.
