Relative source path causes NS_ERROR_FILE_UNRECOGNIZED_PATH error

[kumar303]

If you run using a relative path to your extension source you'll get an error like this:

$ web-ext run --source-dir beastify/
run: WebExtError: installTemporaryAddon: Error: unknownError: Could not install add-on at 'beastify/': [Exception... "Component returned failure code: 0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH) [nsILocalFile.initWithPath]"  nsresult: "0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH)"  location: "JS frame :: resource://gre/modules/commonjs/toolkit/loader.js -> resource://devtools/server/actors/addons.js :: AddonsActor<.installTemporaryAddon< :: line 23"  data: no]

Btw, I still experience this error when using webext plugin on webpack.

To solve this I have to do the following inside webpack.config.js:

plugins: [ new WebExtWebpackPlugin({ sourceDir: path.resolve(__dirname, 'dist'), startUrl: 'https://www.finn.no/realestate/homes/search.html' }), ]

If you type sourceDir: './dist' you will get the error.
