We used the Github PowerUp for quite some time but it stopped working completely at some point last week. We disabled it and re-enabled it. We also removed personal preferences.
Now when clicking on the Github PowerUp and then "Edit PowerUp setting", nothing happens and Chrome (version 86.0.4240.80 on macOS) console indicates:
```
Failed to handle show-settings. {error: "no plugin handles this command", id: "55a5d916446f517774210004"}
Failed to get authorization-status. {error: "no plugin handles this command", id: "55a5d916446f517774210004"}
instrument.js:110 Error, timeout while initializing index iframe for https://github.trello.services/index.html?ver=06487f4b1cd0. Timeout=30000ms
```
Firefox displays similar messages. In addition, Firefox displays the following messages:
```
The resource from “https://github.trello.services/sentry.012d105c.js” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).
The resource from “https://github.trello.services/github.e819f7fc.js” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).
```
This is also true in Private Navigation Mode.
