I am not sure what you’re working on but from your answers I’ve read you seems to need access to a lot of information with a few keystrokes, like searching for a keyword or tag.

In my opinion you are using the wrong tool for that. Ditch the browser and learn about the Zettelkasten way of working. It is really powerful for plenty of applications like science, studies, dev, or even the way I use it, author repository of ideas/concepts/stuff I need when writing a book.

You can do that with several software but I like obsidian for that (and because of all its plugins you could probably find something to automatically copy webpage content)

On the downside side :

• You’ll have to learn Zettelkasten, Obsidian etc
• Obviously do the work of writing (or copy pasting) your vault.

But on the plus size :

• You’ll have all the information you need at your fingertips, searchable with keywords, tags, associations etc.
• Everything is basic text MD files so it will still be readable by any text editor or terminal in the next century.
• You can have images, run code, do some mathlib, jupyter etc inside.
• Text is light, easy to store, backup and retrieve.
• If you do good enough you can have a satisfying visual representation of your new brain, kinda mindmap (which is also possible)
