Very useful add-on for my research! I always want to refer to the URL that leaded to an interesting piece, but with many tabs it would be complicated without this, even more if the original tab was closed at some point.

Thanks for a very handy extension, that works very well.
But today there's a big problem with the update. If I allow the update to install, it installs Text Rewriter.
I never installed Text Rewriter. Could it be that somehow you or Mozilla mixed up Text Rewriter and Tab Origin?
For the moment I blocked updating.
