Duplicated post please continue with /questions/963270 for my company im building a VDI image with Windows XP(yes very old :-). we have Internet Explorer 9 and Monzilla Firefox installed. When i Use IE everything is working can visit all websites. When i Use Firefox i can go to the www.google.com and to www.monzilla.com But when i go to www.nu.nl or www.telegraaf.nl or www.tweakers.net (dutch websites) then i see a flash of the site then it closes Firefox. I have installed firefox again but with the same results. i have tried versie 19,20,21 and 22 but all with the same results. I find some answers on your site but they dont solve the problem. we have a old enviroment with Firefox version 10.0 and there it worked oke , can visit the sites. i have compaired the setting between the image with firefox 10 and firefox 22 and they are the same. kind regards Patrick
