just so you Q faggots know, the latest version of firefox has a full-page webpage screenshot maker that works astoundingly well for off-line archiving. It can be used with console commands too to automate archiving websites and threads.
To use, just right click the website you wish to screenshot, and click "take a screenshot"
firefox is still Soros trash so don't main with it, but use the screenshot feature
