Experimental Features

More info: I have several computers here (on the same network) that acts exactly the same way (they are using firefox sync). I have tried doing a firefox "refresh" with the same results. Interesting thing i found is that if i go to the site just when I started up firefox it works, then it stops working again

thanks, please enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named security.tls.version.max - right-click and reset that entry to the default value. hopefully that should address the issue - in case it switches back on its own after a while please have a look into your extensions, maybe one of it is tampering with this setting...

ooh, default was 3. And now of course it works! thanks a bunch!

on a tangent: pretty sure I didn't change that manually, any ideas as to how this changed?
