jquery.js Unresponsive with Mozilla 3.0.4

[trac@…]

Clicking on any link on a Browse Source page with at least 1100 files or directories the following error is generated in Mozilla Firefox 3.0.4. This includes any of the Trac navigation such as Wiki, Timeline, etc. Stopping the script does load the next page. This error does not seem to occur in IE6.

A script on this page may be busy, or it may have stopped responding. 
You can stop the script now, or you can continue to see if the script will complete.

Well yes, hopefully they'll fix that in newer version of Mozilla. No other browser I've tested has this behavior.

Upgrading jQuery to 1.3.1 also doesn't improve anything.

(keeping the ticket open as a 3^rd party issue)

It's even more funny on a page which holds 10000 rows (right, it's my test page for #5782). Firefox's memory keeps going from 400M to 800M and back, each second, CPU at 100%. This goes on since 5 minutes now ... ok finished. Thank you Firefox for not crashing ;-)

#6101 would definitely help.

Same problem here,

FF 3.0.6

problem seems to be in jquery.js:11 (1.2.6)

FF 3.5 is still very slow when leaving my 10000 entries test page, but at least doesn't show an error. It's now more like 30s than 5 minutes though, which is probably bearable.

I always thought this could be a FF bug, as in Chrome leaving that page is nearly instantaneous. But when testing with Safari, it seems that there's indeed a 1-2 seconds delay that could be attributed to Javascript. So maybe there's something we can optimize...

Perhaps update to jQuery 1.3.2 which is the actual one would be a good idea
(even if its not the problem here perhaps)
... but to be up to date, since most people use 1.3.2 now

Replying to cboos:

No longer a problem with FF 4.0b10.
