Where do you want to remove the favicons?

Is that on the Bookmarks Toolbar or do you just want to remove them all everywhere?

• Bookmarks Deiconizer: https://addons.mozilla.org/firefox/addon/bookmarks-deiconizer/

If you just do not want them to show up then you can set these prefs to false on the about:config page.

• http://kb.mozillazine.org/browser.chrome.favicons
• http://kb.mozillazine.org/browser.chrome.site_icons

het probleem is niet opgelost. de favicons links naast de favoriete websites wil ik weg hebben. niet boven in.

You still didn't tell where you want them removed.

Can you attach a screenshot toshow which icons you mean?

Use a compressed image type like PNG or JPG to save the screenshot.

i do not want all the favicons just at the left site of the websites. for example just beside Lavendel.pdf or left of vimeo. I hope you can solve this problem thanks

Sorry, I don't know of a way to remove the favicons in the sidebar.
Those are beyond the scope of userChrome.css and the only way to remove them would be to disable the favicons altogether and remove the existing favicons from the places.sqlite database file.
The latter can be done by restoring a JSON backup.

i have removed a lot of favicons one by one. unfortunately i still don't know how to remove them all at once or refuse them in the future
