Firefox freezes as if perpetually loading - it is caused by 'static' pages. Examples are gstatic of google, ebaystatic of eBay or geekdo-static of boardgamegeek.com (all .com extension). It has something to do with a script because after I installed No-script this stopped the freezes as long as I did not whitelist those static pages. If I do whitelist them the freeze will not occur every time but about once every two times I visit the site or move from one page on the site to another. What happens is that Firefox just shows its busy you can click nothing on the firefox page and the only way to exit is by using TaskManager to close Firefox. The only potential additional thing is that my hosts file is quite extensive in blocking tracking and advertising sites but until the Firefox updates of May this never posed a problem. The issue is getting frustrating as many sites simply dont function unless you allow their static page to run a script, it then becomes hit and miss for me to carry on browsing. Thanks for any help.
