I have about 20 sites bookmarked with just their favicon that are sort of “first order access”, though I use some of them more regularly than others. At random intervals, one will catch my eye and I’ll think “I haven’t used that in a while, I don’t think I need that up there anymore” and I’ll remove it, usually while I’m at it I’ll remove others too. I have about a dozen folders too, these are more long-term storage, e.g. I have one for all my financial institutions (not to brag but I have several student loan servicers 😣), one for network security tools, one for rare media finding tools, etc. These are used less often and they usually get put there after I’ve had to go look them up several times. I tend to keep it well pruned though, I think I have maybe 200 distinct sites bookmarked.
