Does it also happen if you switch off spell checking?

Comment 2

Even after spell check switched off, I am facing the same issue. Right now for editing data using chrome ( any how I am missing my Fav.Browser FF :( )

FF is hanged for morethan 10 minutes to replace the whole data (300 KB) in a textarea. After 10 minutes the data is replaced. But chrome is replacing the same in few seconds. Are we missing something on FF

Hi Chandru, do you know if accessibility is activated? Usually Firefox's accessibility is activated when a screen reader or other AT is detected, but also for some Add-ons such as DOM Inspector.

Confirmed this on latest nightly without any add-ons. I came across this while trying to use JSLint, but no version of firefox could handle this.

1. Visit http://www.jslint.com/
2. Copy all the text (JavaSript) from http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js
3. Paste the text into the JSLint text area
4. ........ hang .........

It's a bug, but not a blocker.

I was just reading through http://news.cnet.com/8301-13924_3-20011592-64.html and was curious: what profiling tools for Windows/Linux could be used to figure out what's going on here?

Looks like this has been fixed (at least as per the STR in comment 4).

Chandru's address is dead, so marking WFM per comment 7.
