This change the favicons of visited links with your favicons in corresponding tabs, not bookmarks

This is an excellent way of blocking that "dark pattern" where a site puts a red dot on the favicon to keep you coming back.

Works perfectly! Thank you, Saber!

super easy to use! my tabs look very nice now :D

update (to ff130) just in time, thanks. its a very usefull add-on for my work.
i have the same webapp on two diferent servers an it works perfect for me.
but.. i cant find a "buy-a-coffee-button"

no star option? Could not get to function at all. Telling note from dev " so if you've bookmarked the page before, this extension won't be able to change it. " Huh?? then why bother? Moot, since it doesn't work even on a new bookmark.

This add-on DOES NOT WORK on bookmarks!!! It is useless, too bad.

It almost doubled my RAM usage with just one tab! Can't recommend.

I have many Google Documents pinned in my browser and all their icons are the same non-descript, beside saying it's a Google document. Since I've installed this add-on, I have a different favicon for each of the document I have pinned. Productivity: increased. Mission: accomplished.

Tried multiple times to get this to cooperate with bookmarks, which is all I need an extension like this for. No dice. Tried with multiple sites that have never been bookmarked, real ones, fake ones, etc.

This isn't really on the dev, it's Mozilla's adamant refusal to allow users to modify icons that's at fault.

Installed 5 minutes ago, couldn't be happier, easy to install, and fun. But also useful, I had two icons for new tabs that I visit daily for work, I was able to change Jetstream to a SOQL icon as I use it for Salesforce and I changed Trello to their own, obvious, Trello icon. Recently switched to firefox for primary work and these kinds of extensions are helping make the switch even better.

Very nice addon! Thanks a lot. I used it to change the favicons of my pinned Nextcloud taps. I downloaded the favicon.ico for nextcloud calendar from github - and used the following URL-pattern: https://nextcloud..../apps/calendar/* I just drag and dropped the downloaded *.ico file to the small window when asked. :-)

Some time after a website is loaded, the custom icon will be displayed. However, when firefox is closed, it does not work anymore.
