This userscript replaces the superlong scrolling marquee of links on profile pages with a selection dropdown so that you can easily navigate to submitted posts, comments, followers, etc. Works on any profile page including your own.
Requires monkey extension to run (greasemonkey, tampermonkey, violentmonkey, et al)
Edit: previous bugs should be fixed on all versions now
You can run them concurrently with each other, just stick the ones that work in one version into the respective extension, no need to migrate them all. That’s what I do. GM syntax has evolved a lot over the years and I don’t think the extensions have 100% parity with each other without using workarounds like unsafeWindow, which is generally frowned upon
