[Bug Report] Show better error message when feedback is blocked due to ad blockers #9371

Description

@ryan953

I was using the Brave browser without any custom config to submit feedback and the feedback couldn't be submitted because of the built-in ad-blocking the browser has. "Shields" is their product name: https://brave.com/shields/

Repro steps:

  • Download Brave and don't make any custom configs for sentry.io
  • Visit pokemon-market.sentry.dev
  • Open the feedback widget in the bottom-right corner
  • Submit any feedback

Notice a few things around the screen:

Brave shields (at the browser url bar)Image

I think tunneling is a very important feature to use in concert with Feedback. This is a case where no error is thrown, users see a cryptic error message a good case of a problem that feedback is designed to capture (so meta, feedback about feedback).
Also, based on the specifics of the network 'blocked' maybe we can improve the error message users see.

To use Brave, and let data flow into sentry:

  • Visit brave://settings/shields/filters
  • In the "Create custom filters" large text area add a line containing domain=*.sentry.io

                I think tunneling is a very important feature to use in concert with Feedback. This is a case where no error is thrown, users see a cryptic error message a good case of a problem that feedback is designed to capture (so meta, feedback about feedback).
                Also, based on the specifics of the network 'blocked' maybe we can improve the error message users see.

                To use Brave, and let data flow into sentry:

                • Visit brave://settings/shields/filters
                • In the "Create custom filters" large text area add a line containing domain=*.sentry.io
