whenever I open sajha.com or any threads of it, the site opens. Threads also open. In the status bar, it first shows 'done'. and then, one kona.kontera.com thingy appears which hangs my firefox. that thing causes my firefox to show that 'debug/report error/dont send' thingy and whatever I click on, it closes the firefox.

I appeal to any tech-savy people or 'better-than-me layman' to help me fix this issue. साझा बिना त बाँच्नै नसकिने भ'को छ।
my firefox is latest version. OS- XP. ad-ons in firefox are colorful tabs, forecastfox,session manager and AVG safe search.
antivirus in computer- AVG free edition.
Firewall- enabled.

btw, it works if I press 'stop' after sajha.com loads or while it is still saying 'looking for kona.kontera.com'. If I do not press 'stop', it will close.

It's not a problem caused by Sajha or Firefox. Some how you got junk in the trunk of your computer and you got to Google the problem to find out if there is some kind of solution. Here is one of the solutions I have found in the Internet:

Try it. May be "Leo" actually knows and the solution works for you.

GoodLuck

Add this addon to your browser

https://addons.mozilla.org/en-US/firefox/addon/1865

and add http://kona.kontera.com/javascript/lib/KonaLibInline.js as a filter..... This will certainly remove these kinds of problem...

Thank you LinQ and whois.
I tried as Leo suggested but that method did not seem to work probably because I could not do as it was supposed to.
then I tried the ad-on. It seems to work a lot.But just now, similar message appeared with some other ad site listed in the status bar and I had to restart the firefox. Looks like, as LinQ said, there is 'junk in the trunk'. If anybody knows how to remove that junk, please help me.
Thanks again LinQ and whois.
