Hey there!
I’ve been creating an app with the help of your app builder Ai – that worked so well that I signed up for your pro plan yesterday.
The only issue I have is with the app preview. I lead a loading indicator forever. the issue is on Firefox. On Safari and Chrome, the preview is showing fine.
What your AI found:
- The app works correctly in Firefox 153 when opened directly.
- The published production app works both directly and inside a Firefox iframe.
- The sandbox preview renders its server-generated HTML in Firefox, but inside the Teable editor iframe Firefox repeatedly aborts platform-injected scripts:
- Turbopack HMR client
- Teable element inspector
- Firefox reports `NS_BINDING_ABORTED`. Without those chunks, React does not hydrate reliably, so controls may appear but not respond.
- Chromium loads the same sandbox preview normally.
- Disabling Firefox tracking protection did not reliably resolve the injected chunk failures.
The actionable platform diagnostic is: Firefox aborts sandbox HMR and `_teable_element-inspector` chunks with `NS_BINDING_ABORTED` when loaded inside the `app.teable.ai` cross-site preview iframe.
Kindly asking you to fix this when you get the chance.
Thanks
Tim

Oh, and as you (understandably) suppress the browser-native context menu (right-click menu), I cannot break the preview out of its iframe.

Hi @Tim,
