Over the last couple of weeks I have encountered problems with scripts completing. I have Firefox 8.0, XP SP3, I run Noscript which I allow certain sites. This started on Facebook only, and has spread to other sites, inc. here and Gmail. Javascript is up to date, as is my antivirus and antimalware. Neither detect any infections but I still get lag and the occasional crash. Oh yes, many of the lags mention wot (Web Of Trust), so maybe I should disable that. My internet is via T-Mobile dongle. Your help and advice is required and requested. Thanks in advance.
