Hello guys, I have an issue here.

Some sites - just a few - takes a really long time to load on Firefox.

One example is A List Apart (http://www.alistapart.com/) which takes more than 30 minutes (yes, minutes, not seconds).

On Opera, ou even through a telnet session, the problematic sites run without problem, fast as expected.

I am using Linux 8.04, running Firefox 3.6.3 downloaded from mozilla site, with a 10M ADSL connection.

I tried many tweaks I found googling, like disable IPv6, and change http pipelining settings on FF's about:config. None worked.

I also used Firebug to find what phase during negotiation is the bottleneck. Findings are in the screenshot.

Well guys, any idea what is the issue? And how to solve it? I repeat, this only happens with firefox (3.6.3 and prior versions), for a few sites only (even sites with much more requests, images, javascripts, stylesheets work fine), and http pipelines and IPv6 tweaks on about:config didn't work.

Thanks
