Enter about:config in the URL bar, then set toolkit.legacyUserProfileCustomizations.stylesheets = true. Then restart the browser.

Hi TyDraniu,

i checked the about:config

but the toolkit.legacyUserProfileCustomizations.stylesheets was already set to true.

unfortunatly., still thanks for the attempt :)

If you have the @-moz-document url() line with browser.xul then you need to change browser.xul to browser.xhtml

@-moz-document url(chrome://browser/content/browser.xhtml){
  (your code)
}

Hi Cor-el

i changed the lines ( i had two apparently of them ) where browser.xul was, and changed it to .xhtml.

Started Firefox, and woehoe... it'"s fixed :)

thank you very much!!!

OMG, apparently, they changed something again in Firefox.. and now it looks all scrambled

it's no longer a long list with all searchengines in a row ( i even deleted some searchengines because i was thinking i had to much engines, but it didn't change the crooky layout )

My code ( but is long, very long :p )
