Appears to be a scam. Does not work even after upgrading to full version. The reason the App and the Website don't look alike is this is all vibe coded AI slop.

The extension page says, "You can export up to 400 messages for free."
After exporting, the bottom page says, "Exported 200 message(s)"
What the hell?
UPD: The developer promises up to 400 free messages on the extension page, but in reality, it caps out at 200. What the hell? I literally installed this entire browser just for this add-on! Is Mozilla in on it with the dev? How are they not finding any violations here?
