Works a Treat Rated 5 out of 5 stars

On a macbook pro os x 10.9.5, no problems at all

Very useful add-on Rated 5 out of 5 stars

Works fine for me with FF47 on Linux Mint 17.3, which is Ubuntu-based. Maybe Cymro2 would like to give it another try? Evidently it's been fixed :)

No restart was required to start using this add-on; maybe that's a Windows thing.

Completely useless. Waste of time.
It gives an error message that says I neet a Mozilla based browser lik Firefox to use it.
Guess what I am using? FIREFOX!

Perhaps it is because I am running it under Ubuntu but surely that is no excuse.
And this is an official ebay product.
They need to get it sorted!
