In the past, i have installed multiple Extensions, not realizing that they’re closed‑Source.
In most of these Cases, i then switched another Add‑on which is open‑Source.
So that this doesn’t happen again, i would like open‑Source Add‑ons or closed‑Source Add‑ons — whichever are less common — to be highlighted with a Badge on addons.mozilla.org, so that i will not be tricked again, into downloading something closed‑Source because it has a similar Name as something open‑Source.
