Hello. Can you make Pale Moon 27/Tycho specific version of your add-on that officially support Tycho/ Pale Moon 27 that is currently in development if you have time to do so and possibility to support other browsers than Firefox? Backend is based to ESR 38 but do notice that front-end is not Australis and it is mostly similar to pre-australis Firefox. While add-on currently works in Tycho official support from you could be nice.
No pressure. If you don't have time then you don't it would be just nice if you could.
If you have time to add official support you could hopefully make XUL/traditional classic toolkit based version as Pale Moon devs like more traditional toolkit based add-ons over bootstrap based.
You can register to forums and ask from Matt A. Tobin if you need more details.
