Fav Icon Refresher 作者： EdCordata

What does this extension do?
This extension simply opens every bookmark in a new tab, waits for it to finish loading, tries to download the fav icon manually and set it, to force Firefox to update it. If the page does not have a fav icon or it fails to download - this extension tries to get it manually, using one of Google services.

Please note that, if the page requires login or has CloudFlare anti-bot protection, the fav icon might not refresh or might have the wrong fav icon - to fix this, you have to open the page and login, if needed.

How to use?
1) Install
2) Click on 'Fav Icon Refresher' toolbar icon
3) Click Refresh all Fav icons button and wait
