Only changes the tab icon not the favicon for bookmarks.

Works fine on Windows 10 at work, doesn't work at all on Mac os Monterey at home

I can't get it to work for pages on my local disk, e.g. a URL that begins with "file:///C:/Users/markb/Dropbox/Shared/Documents/Web%20Pages/How%20To/"

did not work on firefox103

Не работает.

When you are on a different tab when the tab loads, the icon will not change.

Very useful. I have just tried it and it changes any website favicon beside the tab title like a charm. But it don't change the favicon in the bookmarks, only the websites without favicon is changed in the bookmarks but the rest which have an icon already don't change. Thanks anyway for the addon.

I have been looking for something like this for YEARS!!! THANK YOU!!!

The only thing I would change or request so far is the ability to use wildcards in the URL - so I could have one entry for an application that takes care of each of my three environments (instead of having to have 3 entries for the same image). Alternatively, the ability to assign multiple URLs to the same image would work as well.

Great addon, but as of late the custom favicons are not saved in the fc preferences when I add them and therefore do not display . . .

It works well for tabs, but Bookmarks can revert.

I specifically got this as I needed a certain site bookmarked but I didn't like how it's icon contrasted poorly with my theme. Now the alternate icon only shows up on the tab and the bookmark has gone back to the old icon which is rather disappointing.

5/5 for initially meeting my use case and being relatively straightforward to figure out,
-1 for reverting the bookmark to the old icon the next time I opened Firefox.
-1 since I can't figure out how to get the bookmark to use the adjusted icon, even though the tab is correct.

This is a very sad review. I cannot recommend this add-on because I can find no easy way to actually use it! The developer doesn't give any instructions, which lacks courtesy and consideration and handicaps his chances of getting anyone to use the thing! Advice by other reviewers who also found no instructions are opaque or technically impenetrable. A good piece of software should either have foolproof instructions provided or be so "bleeding obvious" (Monty Python quote!) that none are needed. This one has neither and consequently must be considered as badly designed for use by anyone other than the guy who wrote it.

Thanks for this extension. Makes finding tabs related to large sites much easier :).

Would be 5 stars if the URL match could take multiple URLs. e.g.

Name: Big-Site Section A
URL(s): https://domain.big-site/a-1;https://domain.big-site/a-2;https://domain.big-site/a-3

At the minute I need a config for each.

Works fine here, however I need to be on the active tab for the icon to apply. If I have multiple tabs open and one of them refreshes in the background, it will lose the icon. 5 out of 5 if this would be fixed!

Was working fine previously. Now it doesn't work. Maybe latest update broke it.

This is exactly what I needed! I like to keep my bookmark toolbar as clean as possible with only icons, but some sites don't have favicons specified and I didn't want them all looking the same, obviously. It could use a bit of documentation on use, as the average user would expect to see some sort of icon to click or something to bring up the options or a new menu option in Page Actions. Otherwise, this is perfect and I hope it stays around!
