Enabling extension breaks strava.com in Firefox

[marvinhagemeister]

This is what https://www.strava.com/dashboard (requires being a member) looks like with the extension being enabled:

This is what the same URL looks like when I disable the extension:

This looks suspiciously like an injection bug (related to CSPs?) that I fixed on Alpine devtools (alpine-collective/alpinejs-devtools#445)

In my case the culprit was injection via extension URL:

https://github.com/vuejs/devtools/blob/main/packages/firefox-extension/src/injection.ts#L2

The fix is here on my end https://github.com/alpine-collective/alpinejs-devtools/blob/141e06645b8e41b6b2fd093b46464b7d90198359/packages/browser-extension/src/scripts/content.ts#L14

Hope this helps
