For a while now I've been quite happy running LibreWolf, with Bitwarden and some other privacy extensions. I've also switched over from Google to Kagi as a search engine; doesn't keep me anonymous, but I do love not being the product for once.
Clipboard history pro: Stores a list of everything you have copied
It's a bit of a privacy headache - as the data is stored on cloud, but it has been so so damn useful to me that I keep using it, and haven't found anything that adequately replaces it.
If anyone has an FOSS alternative that stores data locally, please let me know :)
