There used to be a Firefox plugin with much similar features. However since the change of Firefox plugin arch, it's no longer available.

There is one for the weird lz4json format they use now: https://addons.mozilla.org/en-US/firefox/addon/mozlz4-edit/

But it is super unwieldy. Pretty much the only way to decode those files without compiling the decoder from source since it has non-standard lz4 headers.

For the few remaining SQLite files DB Browser works great.

I remember using this back in the day, cool stuff!
