Thanks for the reply. Everything back to normal here too. I think I caused the problem myself by syncing firefox profiles on different computers using Dropbox. Not sure what the details are, but it seems it affected javascript performance on some sites.
Have given up on the syncing project and everything's back to normal.
I'm a teacher and learning technologist working in further and higher education in Sheffield. I'm very interested in how developing online technologies affect the nature of work, knowledge and teaching and learning.
Anyone else having this issue? I'm on a mac and yes, I have several addons!
