I know this is a bit of a dead thread, but things are changing slowly in the web extension world that may inevitably impact Hotpocket Helper.

The long and the short of it is that, with Manifest V3 being implemented on all Chromium based browsers by Janurary 2023, Tampermonkey cannot function as Manifest V3 exists right now. A fair amount of complaining is currently ongoing behind the scenes that do not concern us, but I think that the maintainers of Hotpocket Helper should begin to accept the fact that extension may not function for much longer than a year and a few months. I am not saying that all is lost, Tampermonkey has a representative in the official "bitch at Google over this" group, but the future is forever growing smaller as always. Eyes should begin to watch progress on Manifest V3 carefully and decide what to do next.
