What are you favorite browser extensions? - Beehaw

What browser extensions do you use that you’d recommend to others? Do you contribute to any FOSS browser extension projects? Are there any non-FOSS extensions that you wish had a sufficient FOSS alternative?

On Safari I use AdGuard (because uBlock Origin is not available), Bitwarden and Zotero Connector.

On Firefox uBlock Origin, Bitwarden, Zotero Connector, Cookie Autodelete, Libredirect and LocalCDN

Ublock Origin, Ghostery, Decentraleyes, and that duckkduckgothing are what I use to avoid the complete BS on most sites on firefox lately.
Doesn't uBlock Origin with the right filter lists obsolete Ghostery?
