Extensions dev

• Manifest 3 vs 2
  • used to define metadata about the extension, permissions, scripts, css etc
  • can be in the chrome store but v2 not
    • v2 is gonna be deprecated and chronium based browsers will follow (brave…)
  • you can do less stuff in general than v2
  • considered a regression by many
    • fakes to be privacy and security oriented because of a conflict of interest
    • enables privacy oriented extensions to be less capable instead of enhancing review process for anti-privacy extensions
    • excuses poposed
      • better privacy and security trough lowering capabilities
      • better performance
• In case you suffer from memory loss :D
  • If you choose to add the popup
    • what? when you click extension ico a little window appear
    • background script or service worker
      • let code run in the background and everything you write there will act like if it’s in the popup and NOT in the webpage
    • content script
      • it’s connected to the current webpage so if you do a querySelector the results should be expected
    • some commands/APIs works only in certain types of scripts
      • bkgr or content
      • so beware to check if that API should be used there or there
      • you need to communicate between different types of scripts with different methods to solve this
