this is an absolute bullshit error and #1 reason why i am tempted to just not use firefox anymore.

@bonifartius Only happen to me if I double select too much.
I've seen this happen on ff for windows due to websites abusing JS/web-workers. And even some addons.

@mangeurdenuage i think it's something (i think it might be dbus) getting stuck somewhere - it works for some time and then it doesn't at some point. it's really annoying if you can't open links from outside of firefox anymore. i can't really reproduce it, which makes it even more annoying.
