Did as suggested, did not fix problem. Symptom is that hotmail does not open mail items (like javascript is not executing). Other symptom - javascript page formatting does not execute. I'm baffaloed.

Try running Firefox in Diagnose Firefox issues using Troubleshoot Mode. If it functions properly in that configuration, then one of your add-ons is the culprit.

Still doesn't work. Is there a way to go from 5 to 4?

Unfortunately not. Mozilla has removed v4.0.x altogether now, so the next one down is v3.6.19 which can be downloaded from here: Download Firefox v3.6.19

Before you go that route though, can you try right clicking a link and then choose "Open link in new tab" to see if it makes any difference.

3.69 works.
