Removed unneeded permission.

Add handling for files without filenames (Path ending / )

- Add Polish language translation (Thanks rafal06 - https://github.com/Erisa/download-image/pull/12)

Added a fallback which should fix most Twitter images for now.

The first stable release.

- The extension will automatically generate file extensions for files which don't have their own.
- Setting Firefox to use "Strict" tracking protection will interfere with this, and the extension will fall back to downloading without generating a file extension.

Adds support for `data:` URIs.
Filename is the first 16 characters of the base64, extension is generated based on the MIME type.

Add back support for Firefox 56.

Adds support for user-provided path/filename prefixes.
Prefixes should end in a / to work as custom relative folders, or can be used without a / to prefix text to every filename.
