Reporting this for a user. Firefox freezes for a bit and then shows the slow script dialog. Line of code *might* be:
{var index=0;var match=null;while((match=regex.exec(this.code))!=null)
Maybe YARR will magically save us?

What is regexp? (I didn't look, please copy and paste for everyone's sake.)
If it's exponential, the complexity limiter will save us on trunk builds, now.

Possibly /"(?:\.|(\\\")|[^\""\n])*"/g against a wall of ASCII.
JS program appears to be a syntax highlighter, choking on a user who accidentally pasted the contents of a DLL.
Changing relimit pref doesn't help in 3.6.4, if that's a thing.
