Firefox favicons for subdirs not working

Question

I am having problems with Firefox bookmark favicons!

 

Example - bookmarks showing same favicon

         

 

Setup:

Two different favicons used on my site -

• justinreina.com - justinreina.com/favicon.ico
• justinreina.com/lifebook - justinreina.com/lifebook/favicon.ico

 

✅ Status:

• These are working for page thumbnails in Firefox/Chrome/Edge
• There are working for bookmark thumbnails in Chrome/Edge

 

❌ Problem:

• Firefox shows the same justinreina.com/favicon.ico favicon for both sites

 

Debugging:

I try the method to clear bookmarks identified here

• SuperUser - Wrong Favicons in Firefox

1. Cleared out! No favicons present
2. Open the justinreina.com bookmark to load its favicon
3. Open the justinreina.com\lifebook bookmark to load its different favicon! Success?
4. Click on the justinreina.com bookmark, which RESETS BOTH FAVICONS to the justinreina.com favicon

 

So this is broken, for Firefox see above. Can Firefox show different bookmark favicons located on the same domain?

Answer 1

I got to solution here, it turns out I had two favicon problems

Issue:

• MediaWiki was pointing to the wrong favicon, which only featured one 256x256 px layer!
