My Recipe for Distraction-Free Surfing
I use Firefox ESR as a browser with these plugins:
- uBlock Origin: blocks ads and annoyances everywhere
 - SponsorBlock: skip sponsoring on Youtube
 - Clickbait Remover: replace Youtube video thumbnails with less flashy ones
 - Youtube Shorts Block: remove all Youtube Shorts videos
 - Improve Youtube: remove comments, recommendations, … from Youtube.
 - Toggle Image Animation: turn off (looping) animations
 - Smart RSS: subscribe to RSS/Atom feeds instead of checking sites manually
 - Sidebery: manage countless tabs and bookmarks
 - Dark Reader: eye-friendly surfing at night, more comfortable reading
 - (Various other settings/plugins, which don't serve to minimise distractions, but improve speed, security, privacy, and special functions)
 
My Dark Reader plugin is set to +10% Contrast and +50% Grayscale to un-flash the Internet, because flashy colours mean dopamine, dopamine means reinforcement, but flashy colours shouldn't influence my browsing habits, and flashy websites shouldn't make the real world seem dull.
