Here's one that works entirely clientside via Webassembly - https://sqliteviewer.app/
Upload your bloated firefox `places.sqlite` and select `moz_places` and it loads it without a hitch... if you trust the website not to steal your browsing history.
Unfortunately sqliteviewer.app is not open source. This one (https://inloop.github.io/sqlite-viewer/) is, though. But it uses a JS reimplementation of sqlite rather than true sqlite in WASM.
