Okay guys, I have FireFox 57 now (Developer Edition), so GreaseMonkey won't work for me anymore. The native Chrome version of BE should be written in WebExtensions, correct? If so, I should be able to use it in Firefox now, without using TamperMonkey (yes, there's a Firefox version of TamperMonkey available now, which I wasn't aware of until now, it's
here if anyone is curious).
How can I install the native (WE) version of BE, or is there a TamperMonkey script I can use?
[edit] Hah, brainfart. I just used the GreaseMonkey script with TamperMonkey. Forgot I could do that. Anyway, I'm hoping that now you can just upload the Chrome version straight to the Firefox Add-on store (or whatever its called) if its WebExtensions.
