It does change the icon of any tab with the target URL, however it doesn't change the bookmark icon. Which is what I wanted. If this extension had worked in the past, it seems it no longer works now. Bummer.

If this app doesn't work on Bookmarks, just where does this thing have any utility? Useless.

With the help of this add-on, the new icons will only appear on the tabs. Unfortunately, exactly where it would be desirable, namely in the bookmarks menu or on the bookmarks toolbar, the old icons still appear.

Does not change favicons on the bookmarks toolbar.

No longer changes the favicons for the bookmark menu. All of my changed favicons have reverted back to their originals in the bookmarks toolbar.

It won't change my bookmarks favicon. What is a "URL pattern"? The URL itself definitely doesn't work. EDIT: If the extension might not work with bookmarks favicons, what's the purpose? Where is it supposed to work then?

hi, thanks for making this extension. It did just what i wanted without the need to adding my own userchrome.css

Добавьте возможность изменения названия вкладки.

Doesn't changes favicon on saved bookmark.

Great add-on to take care of one of the nasty Firefox shortcomings. I noticed that Firefox sync did not sync my Favicon Switcher settings to a new PC, is there a way to transfer my settings, or plans to make it work with sync or to include an export/import feature? Thanks!

Hi! Excuse me, I installed this extension but I didn't understand how to find the Url imput box in which you can customize the favicon, can you help me?

It does it's job very nicely except when I try to do wierd things like go to ip addressed sites. If I have locations like 192.168.1.10 and 192.168.1.11 but also define an icon for 192.168.1.1 the ..1.1 icon gets applied to all three sites. I suppose I could just name everything in the local dns (or hosts file) and use names instead but this limitation seems quirky. :-)

The solution I ended up using was to define full ip and port for all sites that stand a chance of colliding. For instance defineing 192.168.1.1:80 keeps it from fighting with 192.168.1.1*:* so I'm golden now that I understand the landscape of the quirks. :-) My guess is the software does a simple search for each expression across all the entries and goes with the first one it matches up with regardless of whether other elements are present in the address. :-)

Nice add-on, easy to use. Unfortunately does not work properly on all url patterns. Some URL patterns will be truncated. This issue does not base on very long url patterns but possibly on special characters like & / = which will truncate subsequent letters.

ナイス！ 似た機能を持っていた旧式アドオンが更新されなくなったので、今のファイアーフォックスでも使える こんなアドオンを探してました。

是非とも末永く更新して頂けると嬉しく思います。

testing: from 10 bookmarks which I tried it only changed 1 favicon in main bookmarks panel but on the TABs it is displayed properly with changed favicons. It is nice simple and easy to use favicon add-on.

Unfortunately I`ve never found 100% working favicon changer/manager yet so to be honest I would prefer to have it as built-in feature of the firefox even though I know it is not the main focus of this browser. Anyway keep up the good work, I hope after some tuning it will work better for everyone, cheers

edit: I`ve seen dev response in the comments that "The current webextension api doesn't allow changing favicons for bookmarks" but imho the best use of favicons is to create bookmark panel with icons only (favicon on the TAB is not so important for me for example).

It's clean, simple, and does what it says on the tin. Since changing bookmark favicons seems to be impossible, the next thing I'd love to see added is a way to overwrite existing favicon replacements. This is a minor issue, but deleting a favicon and adding a new one is a bit tedious.

Nice tool! - Instead of uploading an image, optional, what do think about the possibility of setting an alternative url as a favicon-resource ("redirecting")? I'm thinking of an often occuring problem of having a bookmark to a login-site subpage without a favicon, though the main url of the page have one. Also in this way the favicon would always be up to date. - Beside that, creating a backup-file per click with all url patterns and icons would be great (i.e. if you have to reinstall system or something like that). THANKS!

I like this extension but I am unable to change a favicon once I've set it for the first time. The only way to reset the favicon in order to change it again would be to delete the favicons.sqlite file from C:\Users\*username*\AppData\Roaming\Mozilla\Firefox\Profiles\*file.default*

I found the workaround but it is annoying the extension itself can't overwrite a favicon it has set.
