Duplicate tab identifier

[Benutzer]

In Opera, if two tabs with the same URL are opened, they are marked with a blue line when you hover your mouse over one of the two tabs. This is very useful because it allows you to identify whether you have opened two tabs that are actually the same.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

And, to boost it up a little, it could allow to group them automatically (or manually with a shortcut/single click)!

Upvoted for this. This feature in the Opera browser is a killer feature that keeps me using it. I always have numerous tabs open, and even just highlighting them the way it’s done in Opera saves a huge amount of time and increases productivity.

Please add it, I really need this feature!
