Awesome plugin. Using it for years.
Also faced issue with signed one "Internet connection issue" Not able to update.

This was excellent, but today has suddenly disappeared and I can't re-download it. I get 'Download failed. Check your internet connection'. Please fix it! It's so much better to have my tabs at the side....But then, while writing this, it has suddenly reappeared!!! Thank you for this app. :)

Unable to download 3.0.11...

Wonderful that this extension is back!
I request for a quick tab search similar to how other sidebar tab extensions are now providing. That will make this a perfect extension.
Also if you could have hiding the close button as an option somewhere that will be nice.

must have

only reason why i am using firefox

Seems to work great and doesnt ask for ridiculous permissions. I appreciate that.

One request i have though. Could it be made into a popout like tabsoutlier on chrome?
