Firefox crashes when performing large quick search

[fermulator]

Steps to reproduce issue:

1. Using Firefox...
2. Open a trac website.
3. Provided we have a ticket (semi-large) with several comments (20+).
4. Copy into the clipboard a sentence (15+ words) from a comment in said ticket.
5. In the quick search of trac, paste that large sentence and perform the search. ... the results will be displayed ... probably only the ONE result of that ticket since the sentence would probably be unique.
6. Click on the link to the ticket.

...

trac will cause firefox to use A LOT of CPU, and the ticket could take upwards of 2+ minutes to load. Yikes!

Sometimes even firefox will crash entirely ...

We suspect this has to do with syntax highlighting javascript from trac itself.

Comparison:

1. Do a quicksearch for the TICKET NUMBER (i.e. #999)
2. trac will automatically load the ticket, and it will be fast!

In the comparison case the only difference I can see is that there wouldn't be syntax highlighting ... ?

Limit number of highlighted words on search

Give this patch a try.

What version of Firefox? I can't reproduce this in 2.0.0.14.
