I'm not familiar with HAR, do I googled it. The wiki page has external
references, one of which points to https://www.youtube.com/watch?v=FmsLJHikRf8
Does this help?
I don't know what behaviour/issue you're chasing down, so I'll just
post how I typically save web pages.
1) Basic screenshot with scrot, producing a PNG/JPG/TIFF. Limited area.
2) ^P to print the page. Works well for pages produced by 'serious'
people, but often unsatisfactory for pages with a high 'coo factor'.
Pagination can be flaky.
3) When only the text is interesting, copy and paste with ^A^C in the
browser, and Paste as appropriate in your favourite editor, ready
for any tidying up.
When you hit ^A (select all), check that everything you want has
been selected (reverse video). There may be things, like tweet
panels, that get omitted.
4) Extended screenshot. RightClick on page, select Take a Screenshot,
click on Save Full Page, click on Download.
The resulting file might be a PNG or JPG, possibly depending on
the proportion of image content. FF might fail with an error,
or fail silently, when too complicated.
Some application can't read such a tall file. Ones that often do:
gpicview, mupdf, xzgv. The last is easiest to navigate by keyboard.
Perhaps something here will work for you.
Cheers,
David.
