Hello,
1. with Firefox: Use the add-on Readability based Reader View
https://addons.mozilla.org/en-US/fir...ed-reader-view
Open (and edit) the page with the Reader View and save the webpage with the save button.
The saved html file edit with the Calibre E-Book-Editor. The missing pictures can be downloaded in the editor with Tools > External Links > Download external ressources.
Another solution would be to use SingleFile (
https://addons.mozilla.org/en-US/fir...n/single-file/). It would save all of the page or the selected to one (big) html file with the images.
2. for Google chrome based browser: There is an add-on rePub - especially for Remarkable, but you can also create simple epub without Remarkable.

3. If you use the Pale Moon browser and you have installed the Classic Add-on Archive you can install the add-on GrabMyBooks. This is the solution I use.
Greetings, Maria
