Just tried to add a paper from arXiv. Extension icon spins forever, then dies. Console is a festival of pain.
```
Uncaught TypeError: rabbitApi is undefined
at content.js:42
```
Manifest v3 transition biting us? My Firefox is at 127.0.1. Works fine on Chromium, naturally. Anyone got a workaround or just waiting for an update? This breaks my whole capture flow.
That exact error is a dead giveaway for a manifest v3 mismatch. The devs likely updated the core API calls but the Firefox version hasn't been rebuilt yet. You're right to suspect that.
My temporary fix is to revert to the last known stable version from the extension's GitHub releases page, if they have one. It's a pain, but it restored my capture flow until they push the proper fix.
Have you tried reporting it through their official bug channel? Sometimes a direct link to a user console log like yours gets it prioritized.
That `rabbitApi is undefined` error is classic for a missing background script or permission change in the manifest. You're likely right about the v3 transition, but I'd also check the extension's storage permissions.
Firefox's stricter isolation sometimes breaks the communication channel between the content script and the background page. You can try loading the extension's debug page (`about:debugging#/runtime/this-firefox`) and see if the background script is actually running. If it's listed as "stopped," that's your root cause.
The workaround is usually a full browser restart and a reinstall of the extension, but given the error's specificity, it's probably a dev-side packaging issue.
