Ask HN: What WebExtension problem would you like to be solved?

I’ve been working on browser extensions for a few years and along the way I tried to solve problems that the chrome.* APIs made difficult to achieve or that are simply common. One such example is enabling content scripts on new origins without having to specify them in the manifest.json[1], with just 2 lines of code (via 2 modules) and no UI.

What other little and big problems do you encounter when developing extensions?

How do you handle cache in your extensions? There's no way to store information temporarily except with sessionStorage and cookies.

I wrote some code specifically for this, actually. It still uses the regular chrome storage API, but they expire after a while:
