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.
Dark Reader : for sites that don't have a dark mode
Decentraleyes
Grammarly: I'm not a native English speaker. I like to write English with good grammar
HTTPS Everywhere
Imagus: for zooming pictures by just hovering
JSON Formatter
Local CDN
MultiLogin : a container like in the Firefox browser
Privacy Badger
Link Grabber : grabbed all the links on the page
Disable automatic tab discarding : I don't like when the tab automatically refreshes when I didn't open it for a while. This extension disables that
Old Reddit Redirect
Reddit Enhancement Suite
Return YouTube Dislike
Snowflake
SponsorBlock for Youtube
For search engines, I'm still using Google. Because I think the results it's more and better (I guess). If not Google, I will use DuckDuckGo or Brave Search
Keep in mind LocalCDN will make your fingerprint more unique. HTTPS Everywhere is unmaintained and no longer needed.... and you certainly don't need Decentraleyes, thats a duplicate of LocalCDN and is also unmaintained.
