Excellent - just what I needed! Technical support is also friendly, responsive, and helpful. I needed a little help from the excellent Guy to get it going but as soon as I understood what to do, it worked perfectly.

Works just about, but changes to favicon does not take effect 90% of the time. I just couldn't figure out why / when it loads a change to the icon.

Would love this but for bookmarks!

Straightforward to use and very useful. Thanks.

works without issue for me.
however: PLEASE add support for capturing groups so we can use backreferences (\1 \2 etc)

Excellent add on for personal customization.
Could use some more tutorial or guide to help new user familiar with the interface.
Also, any specific pixel the png file should be to be able to use for custom favicon?

For anyone who searching for option to bring back the beloved blue bird, you will not disappointed.
Short guide on how to proceed:
Rule Name: name of the rule for easy identify
Title Regular Expression (optional): Twitter / X
URL Regular Expression: https://twitter.com/
Custom Title: Twitter or whatever text you want to replace the tab title with
Custom Favicon: Be sure to use .png file and find transparent picture for best result. Try to resize the pixel of the file if fail to replace the icon.

Not bad, but it'd be really good to explain (with examples!) how matching works - for example for urls.

In-situ help would be best, so one does not have to dig for the manual when this information is needed.

I cannot tell if this extension would actually work as intended since you cannot actually save any rules.
Once you click save, other than the selected favicon appearing above the save button nothing else happens.

When you first set icon #1 (svg) in the application, the icon for this site on the start page in the "Top Sites" block also changed (this is good)
When you change the icon in the application for this site to another one, the original icon # 1 remains in the "Top Sites" block
It does not change either in the regular way (by specifying a link to the resource), or when the rule is deleted, even when the application is deleted. This is bad. Clearing your profile is not an option. Can you at least tell me where the fox stores this data

P.S. w10 FF dev edition 100.0b9 app ver 2.0.2

P.P.S The same effect on the icon at the bookmark to this site in the bookmarks bar

P.P.P.S I found a workaround - in the settings in the shortcut in the Top Sites I specified the same domain, but with a slash on the right (and in the application the domain was without a slash) and then I already specified the desired icon in the regular way.

I thought it deleted all my tree-style tabs in the left panel but actually it just changed the left panel to bookmarks - I could easily change it back to Tree Style Tab using a dropdown there. So no problem in that regard.

Overly complicated - I want to give the tab a new name and have the extension figure out to do that based on the URL. This is too complicated to use. It should be doing the regular expressions and rules behind the scenes.

Yay, I get it. Sorry to bother you! 👌

Не работает, после заполнения полей названия и адреса и выбора изображения нажимаю сохранить, появляется выбранное изображение в настройках расширения, после обновления страницы с настройками, все настройки сбрасываются на пустые поля. FireFox 100.0.2 x64. Когда исправите, сообщите мне.

Stopping working recently without any changes to configuration.

Works great & easy to use...

I use it to get rid of a nasty animated favicon on Telegram Web.
The favicon part works great... When I change the tab title though, there's a small flickering going on, probably every time Telegram pings for an update and the tab title has to be overwritten again.

If anybody has a fix for this it would be greatly appreciated...


Other than that I agree with Pablo Vieira that an extension shortcut on the toolbar would be more intuitive. :)

work it as intended, nice addon
but there's slight delay when the site gets fully loaded, can you improve this by any chance?

Great addon. I suggest just two improvements:

a) Don't force the user to go to Extensions->Custom Tab...->Options. Let the user do it directly by using an extension icon on the toolbar.

b) You may also use Firefox's SideBar to show and edit all defined custom tabs.

I can see you have listened to my suggestions. Thank you very much!

all saved options will reset after Firefox restart.

Super!
