I've been using custom icons for all of my 36 shotcuts on Firefox start page. Today I opened Firefox and my icons are gone, Firefox slowy created its own ones and now I can't refresh them to bring back my own, despite there are my links pasted into entry. This is how it looked like: https://i.imgur.com/4C9jaqK.jpeg and now it's like that: https://i.imgur.com/VDIoggt.jpeg absolutely horrible and it's not the first time Firefox did that. It's really time consuming to bring back old icons one by one, I have to upload each of them again to get new links, because somehow Firefox sees old links being in use and there's no way to refresh preview of them. Please give me faster method to bring back my old setting, I really hate changes so much!
