Modifying this addon...

[cheater]

Hi, thanks for your addon! Would you mind making a similar addon that does just one thing differently? Rather than add the hostname to the title, it would add the name of the current Firefox profile.

Alternatively, if you were kind enough to tell me the exact steps to turn the git clone into an xpi, I could try forking your repo and adding the functionality myself.

As far as getting the profile name: this addon (incompatible with FF57) does that so maybe the new addon API still allows that? https://addons.mozilla.org/en-US/firefox/addon/show-profile/

Thanks!
