@onemen Use this [BootstrapLoader.zip](https://github.com/user-attachments/files/20981093/BootstrapLoader.zip) Put into the `utils` and replace `bootstraploader`. Mind the file name. No change to the addons. You'll need a path under `utils` called `addonManifest` to host...

@onemen @marty60 Add a ```js Cc["@mozilla.org/chrome/chrome-registry;1"] .getService(Ci.nsIXULChromeRegistry) .checkForNewChrome(); ``` somewhere before `autoRegister()` seems has effect.

Don't do`deleteTemporaryFileOnExit(tempFile)` for now? ```js let tempDir = Services.dirsvc.get("ProfD", Ci.nsIFile) tempDir.append("browser-extension-data"); tempDir.append(addon.id); function createManifestTemporarily(manifestText) { let tempFile = tempDir.clone(); tempFile.append("chrome.manifest"); let foStream = Cc[ "@mozilla.org/network/file-output-stream;1" ].createInstance(Ci.nsIFileOutputStream); foStream.init(tempFile, 0x02 | 0x08...
