Thanks for your rating. It's great to hear that you like the add-on.
However, I see your point of not liking the random tips beings shown.

I can reassure you the likelihood to see such a prompt is very low though and e.g. only shown after you have used the extension for some time and e.g. not shown again if you have dismissed it explicitly twice.

As this add-on is open-source, you can also check it's source code at https://github.com/rugk/offline-qr-code/blob/main/src/common/modules/data/Tips.js, if you are interested in the technical details or want to verify my claims here.
Also notice there are other helpful tips that may occasionally been shown, but they are really kept to a minimum and many users do e.g. not know that they can use a hot key or help the extension by translating it.

I am afraid this has disturbed you and want to apologise.

Let us know if this helped by adjusting your voting.
Apart from that, if you have any other ideas or issues, feel free to get in touch.

Thanks for your rating. It's great to hear that you like the add-on. 😀

As you correctly noticed, you can access the extension with the shortcut Ctrl+Shift+F10 by default. This hotkey can already be modified in the Firefox add-on settings. See https://support.mozilla.org/kb/manage-extension-shortcuts-firefox for more information.

It would be glad if you could upgrade your voting to 5 stars if that solves your problem.

If you have further issues or questions, feel free to ask or suggest a feature by opening an issue on https://github.com/rugk/offline-qr-code/issues. Thanks.
