Waterfox adds favicons to bookmarks

[Anonymosity]

How do I stop Waterfox from adding favicons to bookmarks? I have set the about:config setting for site icons to false and I also added a setting to block favicons with a user.js file and that got put into prefs.js as well. The browser still wants to add the icons. Would adding a setting to limit the image icons max size to 0 do the trick?

I finally found the solution. There is a file in the profile called favicons.sqlite. Deleting it, then starting and closing Waterfox, and then locking the file to make it read-only got rid of the favicons.

browser.chrome.site_icons -> false

browser.chrome.site_icons -> false

That was already set. It did not stop the favicons.

it prevents loading of favicons (also in tab) and storing. already present favicons are still used.
