Hello. I'm developing multi browser extension and now want to implement nice thing - inline extension installation. As I know - https://developer.mozilla.org/en-US/docs/Installing_Extensions_and_Themes_From_Web_Pages#Web_Script_Example - this is old method for old style addons. Also, for now, Firefox doesn't support chrome inline installation flow - https://developer.chrome.com/webstore/inline_installation I know only one method - make button with direct link to signed XPI file that I can download from admin panel (after firefox team review). But I don't know - is it legal and a little bit worry that you can remove my extension from store if I will use this method. Which is the best way to implement inline extension installation? Thank you.
