Download & Auto-Rename by xingshuai

Stop fighting image.png, image(1).png, image(2).png. Save every download with a clean, unique name — automatically.

Right-click any image, link, video, or audio, choose Download & Auto-Rename, and the Save As dialog opens with a tidy filename already filled in:

20260914_153012_example.com_image.png

That's date + time, the source website, and the original name — so files never collide and you always know where each one came from.

Why you'll like it

• No more overwrites or clutter — every file gets a unique, sortable name.
• Know the source at a glance — the site's domain is right in the filename.
• Zero setup — install, right-click, done. Nothing to configure.
• Truly private — collects no data, sends nothing anywhere, and never reads the pages you browse. It uses only Firefox's download and menu APIs, locally.

Good to know

Firefox doesn't let add-ons rewrite the built-in Save Image As dialog, so this add-on adds its own right-click item to do the job.
