Excellent and incredibly useful add on!!! You can also save the website URL within the Single File HTML file by turning on the option "include the infobar in the save page" option.

I'm simply loving this extension! Works great. And constantly maintained by the developer👍

FOR THE DEVELOPER, BIG PROBLEM FOR ONE WEB PAGE:
For the web page "The Best Small Business Accounting Software for 2021" at https://www.pcmag.com/picks/the-best-small-business-accounting-software
On this web page,
---the section "Our 10 top picks", only the visible part of the table is saved!
---the section "the compared specs" table, again only the visible part of the table is saved!

Otherwise, I want to thank the developer for this addon that nearly all the time does a great job at saving a web page.

It's great!

Thank you for this helpful add-on!!

...it works as intended
...has many useful options
...is a great time saver
....is dead simple to use

One suggestion is to add tool-tips to the formatting page with names for the different tools (Highlighter, Notes etc.) so that it's clear what each button does.

That's it...thank you once again for this wonderful add-on! Maybe browser makers should think about accepting it as a webpage saving standard! :)

Since it is the best in what it does, I have to give it five stars.

It would be even better if it did not require the "access-your-data-for-all-websites" permission, but I being it "recommended" (and therefore I hope checked) by Firefox, I trust it.

For details on the dangerous permission, see:
