Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Thierry Excoffier]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.9.2) Gecko/20100115 Firefox/3.6
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.9.2) Gecko/20100115 Firefox/3.6

When using JavaScript to update a table content,
FF is very slow (unusable).

There is a time lag AFTER the updated table content is dislayed.

Each table update is slower than the previous.

Reproducible: Always

Steps to Reproduce:
1. click on 'Sort' to sort the column
2. when the table is sorted, try to scroll (it is frozen some time)
3. when unfrozen, try to sort another column.
Actual Results:  
Firefox popup a window asking if we want to kill the script.
 

Expected Results:  
A near instant sort as in the other browser :
Chrome, Opera, Konqueror and IE.

This bug was also in FF 3.5

With less lines in the table we can see that each sorting
take more time than the previous.
