On linux, with kde, there is usually a browser extension preinstalled called plasma integration.
It makes it so that when you search from the KDE equivalent of window’s start menu, you can also search open browser tabs or history.
I close all tabs once I’m done, but when trying to solve a programming/devops related problem, having lots of tabs open lets me see more than one approach to a problem, along with opinions, side by side.
And research in general requires a lot of tabs, in my experience.
