795761 - Enhanced responsivity for tabs

Status: RESOLVED DUPLICATE of bug 718121

(Firefox :: Tabbed Browser, enhancement)

Description

[sworddragon2]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:15.0) Gecko/20100101 Firefox/15.0.1
Build ID: 20120907073726

Steps to reproduce:

1. I opened a site which needed lot of cpu time (for example http://www.thegeekstuff.com/2010/05/bash-variables/).
2. I tried to close the tab after the page was loading too long (the site above seems to bloat up the memory usage because of a loop or something else).


Actual results:

Firefox hasn't reacted anymore.


Expected results:

Firefox should seperate the tab bar and the websites in a way which makes it possible to close a tab if a website is freezing (for example with different threads).

I couldn't reproduce the freezing on my machine, but I will confirm this issue as an enhancement request.

[e-mail], please try to reproduce the freeze on a clean profile and log a new bug for it if it reproduces like that.
