Certain sites (the Autodesk EAGLE site was one of them) seem to just about completely hang with current Firefox for me. Might have something to do with having NoScript loaded; NoScript had an update within the last few days that seems to have fixed the Autodesk EAGLE site issue. The issue manifested itself with a nearly completely hung tab, and all other tabs hung as well, with nothing clickable. Clicking the X to close the tab took thirty seconds to a minute to close; clicking X to close Firefox completely took close to a minute to close. System specs: Core i7-3740QM with 16GB of RAM and an SSD system drive. It's not due to a slow system. I haven't experienced the issue since NoScript updated yesterday, so maybe that was related.
