Copying an unformatted table of 1k+ rows will crash the firefox client. It seems to enter into a loop that it very rarely recovers from and I've left it up to 30 minutes without any recovery. My usual data set size is a table of 2-5k rows of 4 columns of short (4-25 char) unformatted text as an output from one of our systems.

Reproducible: Always

Steps to Reproduce:
1.Create a table of 4x2000
2.Manually select the whole table.
3.Copy the table
Actual Results:  
Client locks up and stops responding.

Expected Results:  
Copied the table to the clipboard.

The same process works instantly in IE with perfect results, this is just a table of raw text values so its hard to see why it struggles so much.

It's not locking up completely any more. Still some rendering issues with highlighted tables adding a 5-10 seconds to tab rendering.
Was that in a fresh profile?
Try Firefox 4, there are some large improvements in rendering speed.
This bug has had the CLOSEME tag for several weeks and the date in the tag is
