Best solution I've found, and I've tried many.

Does it says.

NYC........

Works exactly as advertised, finally pressing Ctrl+S actually does what it's supposed to instead of making a broken document.

SingleFile

This can deal with many pages that are not correctly saved in default setting of firefox

Excellent archival tool! These days you cannot trust that any page will be available or drastically modified in the future.

SingleFile grabs everything or just parts, incredibly usefu and I use this along with Obsidian webclipper + Obsidian.

thanks

Good Browser

impressive!

I rarely give reviews but this one I must. It worked out of box. Can do things even FireShot can't such as saving the page or portion of it in a single html file! Very useful for saving a website or web page on Internet Archive.
