GMail chat stopped working in safari 5.0.3

Question

I just started using safari for everything again, but for some reason in the past few days chat in gmail has point blanked refused to load,
I added a few extensions like adblock and image block and stuff, and I have gone through them all to see if any of these are responsible for this bug but I haven't managed to isolate the problem.
Anyone got any ideas?
I am not back to using gmail in chrome, which for some odd reason has a tendency to go stale all the time and needs reloading, and chat seems to work fine in there...

tried it with a test account and still the same ploblem.
At this point since it's a system wide problem. You can put off troubleshooting third party add-ons.
You need to boot from your install disc, run Disk Utility. There may be errors on the startup disk that need repairing. I'm not talking about repairing permissions, I'm talking about the startup disk.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
(In Mac OS X 10.4 or later, you must select your language first from the installer menu)
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your startup disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. Make sure there is always 15% free space.
