1311312 - [meta] Enable eslint rule no-undef in toolkit/.eslintrc.js (and everywhere that covers)

Status: RESOLVED FIXED

(Firefox :: General, defect)

Description

[Mark Banner (:standard8) (afk until 21st July)]

no-undef is very useful for picking up mistakes and referencing of unknown variables. We should enable it on browser/

This work is likely to cross several bugs, so this is the tracker for it.

I just filed Bug 1323167 as the next big one - we need to sort out how we're dealing with the content code. I think this will fix the majority of the ~5000 errors that we have remaining when we enable no-undef.

I don't think its worth filing others until we get that one resolved.

We're now down to about 3500 errors in my local tree, and I'm mainly driving the patches through for these, so I'll take the meta bug for now.

I'm declaring this done. We've got it enabled pretty much everywhere that toolkit used to cover (now a recommended config). There's some tidy up to do, but I'll work on that in separate bugs.
