This is a tiny webextension to forward matrix.to links to an open Riot tab.
This only works if you are using the browser edition of Riot, and only if you are using riot.im/app or riot.im/develop. In the future, this will be configurable.
There is a zip file that filefox will install from under releases. You can open the file in Firefox by going to:
Addons > Cog > Install Addons from File... > Open the zip file.
You need to disable xpinstall.signatures.required
in about:config
for Firefox before installing because Firefox only allow addons signed
by Mozilla, and I've not gotten around to getting it verified. You can
open the zip yourself if you don't trust that I've packaged it correctly.
