Thanks for checking it out @proftech. It should theoretically behave the same as Chrome (it’s exactly the same file I upload to each extension store) but there may be some unexpected issues due to how new Microsoft’s implementation of browser extension support is. I look forward to hearing how you get on with it later.
Thanks for raising your concerns @Harri_H - I’ve responded in your related topic at Kee extension for Edge
The link that @SecretKeeper helpfully posted contains the extension files that I upload to Firefox, Chrome and Edge stores (as well as the exact source code that was used to generate the files) so if you want to perform some extra authenticity checks you can start there.
