I am basically convinced we can remove this here and now. We have almost no uses in the browser and very low add-on usage. No other browser implements this either.

v2 - Remove quote browser/mobile usage

I believe pref names are relatively sane, so we don't need to escape anything.

I'm not particularly happy removing this quoting without figuring out an alternative: finding another escaping method, or mapping keys in a more sophisticated way that doesn't require escaping.

I tested. about:config allows me to create prefs with backslashes and quotes in their names, and there is certainly an extant pattern to have computed pref names like:

  extensions.bookmarkdeduplicator@foxhatdev.install-event-fired

or

  urlclassifier.keyupdatetime.https://sb-ssl.google.com/safebrowsing/getkey?client=navclient-auto-ffox2.0&


In short: this is a change you need to _prove_ is safe, because I see nothing to suggest that it won't break.

Okay let's use CSS.escape there as well. I indeed didn't consider this case. I don't consider about:config to be critical anyway.

CSS.escape(' \\"') gives "\ \\\\""
