1428402 - Add a line to about:support that identifies if the user has userChrome.css or userContent.css

Status: RESOLVED FIXED

(Firefox :: General, enhancement, P3)

Description

[Chris H-C :chutten]

A lot of time can be wasted diagnosing bugs that eventually, after some long investigation, turn out to be silently-failing userChrome.css selectors.

To diagnose problems of this sort faster, perhaps we could annotate about:support to include whether the user reporting the issue has user stylesheets?

cat the entire contents of userContent and userChrome into an about:support heading?

Comment 2

[Chris H-C :chutten]

Strings have a nasty habit of occasionally containing data we don't need (or want) to know. I think we can get most of the benefit from something along the lines of:

"User CSS: {chrome|content|<none>}"
