File Cabinet by Ashforge Addons

File Cabinet helps you organize your open tabs using a familiar filing cabinet approach instead of traditional tab groups.

Rather than leaving dozens of tabs cluttering your tab bar, File Cabinet lets you file them away into Cabinets → Drawers → Folders → Files, making large browsing sessions easier to manage without losing your place.
