I have this exact problem! About a year ago I built https://fetcher.page which fetches updates for me every 10 minutes or so, filters the ones I've already seen, and then notifies me of new updates.

It's not perfect, but at least I thought reopen 5 websites like 50 times a day.

I rebranded it as a social listening platform a couple months ago, but one can still use it for its initial purpose. Let me know if you find this useful, can grant free access.
