Can't load properly youtube.com, a blank page with text is loaded

more options

Firefox can't load properly youtube.com, even in safe mode. Sporadically it can, but then if i click a video or even reload the page it shows again the blank page. Besides also the gmail inbox page has problems displaying the buttons (even if the buttons still work).

If you have Avast then try to disable HTTPS scanning in Avast Web Shield.


You can check the Net log and the Network log in the Web Console (Firefox/Tools > Web Developer) to see if content fails to load or possibly is blocked (file size is zero).

Use Ctrl+F5 or Ctrl+Shift+R to reload the page and bypass the cache to generate a fresh log.

Did you disable stylesheets? That sort of thing happens if stylesheets are not used. Check the View > Use Style menu and see if "None" is selected or "Basic Page Style" or "Default Style". You do not want to select "None".

YouTube style sheets are loaded from a second server. Can you access the style sheet directly using this link:

https://s.ytimg.com/yts/cssbin/www-core-2x-vfl74wlma.css

It should open a tab listing a "wall of text" (style rules written without spaces or line breaks), starting:

body{line-height:1;text-align:left;text-align:start}menu

If you get an error or if Firefox won't display the page but forces a download, that may help explain why YT appears unstyled.
