все гениальное просто! еще бы так же просто группировались эти вкладки как в Вивальди

Absolutely does what I wanted. Thanks!

I feel like you read my mind. This was the addon I was looking for, including the little bit more haha
If you update this: feature suggestion: assign the domain to the window name

'Order Tabs by Domain' is the only add-on I've found that actually does order tabs by domain - very well & consistently.

Was looking for this simple functionality of long time. Thanks for this!

This was a very useful add on for me until tonight when it along with most of my other add ons were all disabled for being unsigned ... update that please?

This is perfect! I was actually looking for the secondary feature — grouping every tab with the same domain into a new window. But I also use an add-on that sorts tabs by domain, so it works out very well for me that this does that as well!

I second Andrej Gorski's suggestion for an option to do it automatically every X seconds or minutes.

Simple and works
