Well I guess I don’t have a particular or consistent system but I can find what I need pretty quickly. I have a few tab groups for stuff like youtube, bandcamp which helps a lot, and I use Simple Tab Groups in firefox which has been amazing (but I’ve only been using one group/window so this is kind of defunct now), but otherwise there are areas of tabs which are related and they are roughly in chronological order. I will manually move tabs so there are areas of certain topics. I know I can scroll all the way to the right for old tabs, and then left of that a specific topic I was learning about at that time, then left of that something roughly related by topic or time, and so on until all the way to the left is the most recent tabs (and then a bunch of pinned tabs that I use very often). It’s like a map of time and topic, and not just a bunch of random tabs like you might imagine.
