i have delete my favicons.sqlite file and rebuild it with Checkmarks, but not all of my bookmarks have get their favicon, but why?
For such cases i use now additional this Add-on: https://03.yfhome.xyz/de/firefox/addon/cache-favicons-for-bookmarks/ but this can also not update all favicons by unknown reasons ... the funny is, firefox itself shows in this cases the favicon in tab but not the bookmark!

Is it possible to make a add-on version which also works on mobile firefox (Android)? Here you don't have any favicons, this looks simply "poor" :-(
