I am trying to break myself of these habits, but they do have some benefits. For instance when I do a web search on a complex topic, I often scan the results, opening the most promising looking results as tabs. Then I look through the tabs comparing them. The trouble is I never remember to close them when the task is done.
Mainly just not having a workflow of going back to close them. So it's just previous work like a view of some logs, a merge request, a link to a file in a repo, a monitoring dashboard, an alert in a monitoring system, etc.
In Chrome, I do end up closing them eventually because there's no more space to work.
For personal:
it's more like a bookmark, but don't often review them rather than open a new tab to research whatever I'm currently curious about.
