CSS isn't rendering in Firefox 25.0. Webpages don't display correctly.
I recently downloaded FF 25.0 on a new computer (Samsung Series 9) and web pages don't render correctly though I used default settings and have same extensions (all in one sidebar and list it). I asked our tech person and he said "Your CSS isn't loading. Try clearing your cache and restarting your browser". This worked but now I find I have to repeatedly do it as many as a few times a day, with varied websites, and once it happens, all websites won't render correctly. I don't want to have to switch to chrome, please help! Here is a screenshot.
