Nice! Finally found the option to not remove tabs when duplicating in another context/container using option scope -> container.

Wow! Excellent Addon! Great Job guys! :-)
It has closed all my Duplicated Tabs, which have been created by this Addon (Tab Suspender).
I give you 5 stars! I hope to keep up the good job.

A great extension that helps me keep CPU usage down by aiding in minimizing duplicate tabs. A plus is that the add-on provides options to simply alert user of duplicate tabs or automatically close them when detected.

Works really well!

Have a feature request:
I run into this case, where certain websites' URL behaves differently, where their hash part causes content changes to the site.
Wondering if I could have a list of websites which have their own specific set of filter configurations (for example on those sites, I'd like to disable "compare with tab title"). Could be specified by domain, or URL pattern.

Don't work in Firefox 52.4.1?
Show number of duplicates on icon
Don't show duplicates on list, shows "No duplicate tabs."

Update rating

I use it all the time.
Only one request: please return the option to "Open popup" on duplicate tab detected!! I've always used it to choose if I want to close it or go back and enter other links... Now I have to choose "Do nothing", and actively look to the small badge number..... Please return the option to open popup!
Thank you!

Great job, thank you. I hopelessly try to find similar addon in chrome store...

This addon is a must have for people opening a lot of tabs :-) . Works great.
And thank you for making webextension. 5/5
