• Fixed Converter Tab Autoclose: Eliminated the bug where Firefox would instantly terminate the extension whenever you clicked the upload box. Firefox users are now seamlessly redirected to the safety of the dedicated reader.html workspace instead.

• Bypassed Cache Persistence Loop: Solved the issue where re-opening the converter kept loading the old document indefinitely. Added smart URL routing (?new=true) that forces the engine to ignore browser cache and serve a clean slate for fresh uploads.

• Restored Confetti Effects: Reprogrammed the Canvas Confetti launcher on-the-fly specifically for Firefox to disable Internal Web Workers, which successfully bypasses strict browser Content Security Policies (CSP) that were blocking the render silently.

The previous version was crashing because:
Firefox uses non-persistent background event scripts for Manifest V3. In that specific environment, importScripts is completely undefined.
The Crash: Originally, the first line of background.js file was importScripts('gemini-service.js');. When Firefox tried to read this line, it hit a ReferenceError and instantly crashed the entire background process before registering any listeners.
The Fix: By wrapping it in if (typeof importScripts !== 'undefined'), we instruct the code:
On Firefox: Safely skip the function instead of crashing.
The update I made to my build.js explicitly embeds gemini-service.js inside the Firefox manifest array so it is automatically pre-loaded without needing that call!
