FireFox 8.0.1 consistently hangs in specific circumstances

Question

Dear Sirs/Madams,
I have a lot of tabs open in use all the time, and normally things work relatively acceptable (not great since after a while FF always crashes). But recently, when I click on certain tabs, FF becomes immediately non-responsive with the typical system mention about that in the title of the window; CPU is fully busy with FF process.
This happens absolutely every time -- no matter if I restart FF, upgrade it from 8.0.0 to 8.0.1, restart my computer, whatever. The link in the tab which causes the hang is this (works perfectly normal in other browsers):

However, this is not site specific problem, since there is at least one another site with the tab which causes same effect. All other links/tabs on that site and on this ZDNet site work normally in FF, nothing hangs.
The most interesting thing is that if I open this link anew, then new tab is created and no hang happens. But when I try to switch to the old tab with the same link, it always hangs.
I can not close that old tab to fix this problem, since once I click on it, FF does not even redraw the window to show that the chosen tab is now active. It immediately hangs.
Is there way to cure this tab without killing my whole session? It has a lot of tabs I need and opening them all anew is not realistic option.
Windows 7 hang error information (I tried translate it to English):

Not sure if this would be any helpful, but Process Monitor utility only returns "Profiling" activity of FF process when it is hang/fully busy state.

Similar problem - my details:
I got a new HP midrange desktop 5 days ago, core I7 2600 8GB Win7 SP1 64b, nvidia GT545 3GB. (My point of comparison is my old HP HDX18 laptop, core 2 duo T9400, 4GB, Vista SP2 64b, nvidia 9600M 512MB. It's been running Firefox exclusively sinc early 2009, with every upgrade allowed as soon as Norton add-ons are available - usually a week or 2 after FF release. 8.0.1 still works great on it.)
I installed FF and began researching problems with audio and usb 3.0 drivers. FF was running slow, almost dialup-slow, which raised concerns about the wifi card. So first I did router pings on both systems - both get about 10ms for a 10000b ping so I ruled out the network as a source of the problem. I got my audio and usb 3 working, and have been troubleshooting FF now for 3 days.
Symptoms are:
Very slow content load (right after loading same content quickly on the laptop).
Unresponsive FF window for 10+ seconds at a time - buttons/links/scroll don't work, can't move window, typed characters are ignored.
Ending the FF process takes 20-30 seconds, and sometimes never ends. When I delete the process tree, it sometimes still will not restart until I reboot, sometimes more than once. On the laptop, 5 seconds.
On the plus side, no outright crashes.
Here's what I've tried with zero success:
Safe mode.
Complete uninstall & (standard) reinstall.
Config tweaks to browser.sessionstore.interval, network.http.max-connections.
Delete prefs.js to reset defaults.
IE9 performance is OK. Installed Chrome but unfortunately I've developed an unaccountable hostility to apps that have no UI.
My ISP is 3Mb DSL with horrible latency, so the TryAgain addon is a must. Speed test results are identical to laptop.
Any thoughts? Thanks, CC
[Edit 17Dec2011]: Well I've given up on FF for now except when security is important - hopefully whatever is wrong with it will be fixed in the next release. I'm getting super response with IE9 and it also correctly renders pages every time - with FF I have always had to constantly refresh to get pages to display correctly.
