Do they have a GitHub site?
Bug 1318532 had a patch submitted which provided a WebExtensions-compatible API which would allow the original implementation to work, but this was spiked permanently because of :reasons: The developer, DW-dev has been gamely trying to provide similar functionality via implementing a browser-managed tiling window manager, but this seems doomed to failure since it is at the mercy of the display rendering on the target OS. For example, on MacOS, a massive shadow is rendered around an active window, which thus renders over the top of a neighboring tiled window.
Doubt this one will get fixed ... unless Chrome implements it. Right now the objective seems to be full Chrome "compatibility" and Chrome doesn't have it.
Why does it matter if they're on GitHub? Firefox no longer has the APIs for many of these extensions to be possible.
I'm not OP, but usually the conversation goes like this:
Person 1: <describes problem with open source software>
Person 2: It's open source. Have you submitted a patch yet?
