For me, I have requested the same since the beginning — just allow me to modify the UI with a markup language.

Or I'll fork, merge all upstream patches down, and work with that.

Currently I have to rely on the AutoHiDPI addon because firefox is otherwise unusable on my system (linux with two screens with very different DPIs).

I also asked for a way to get tab thumbnails done, and to replace the entire bookmark and omnibar system.

But no. Now I'll have to fork Firefox to get a usable browser.

Did you request this with your plugin/addon developers, or with mozilla yourself through their many methods of contact for this if you are a plugin/addon developer?

I don't get why addon/plugin developers not communicating upstream is the problem of upstream.

I communicated it through the bugtracker comments and the comments on the Mozilla blog.

On every announcement regarding this for the past months.

I’ve not gotten any answer, nor has any solution been implemented or suggested.

It's troubling that your comment has been downvoted.
