Not sure when it started but firefox irregulary takes forever to load a page. I have pinpointed javascript as cause for this because when I disable javascript all is good. It doesn't happen on every site, mostly I think on news sites with lots of content. It doesn't happen here at xenforo. I haven't installed any add-ons prior to this happening. Latest firefox is installed (although it happened a version before). The error console doesn't show up anything javascript related for some reason. Browser cache is empty. Other browsers work.
Any ideas?
