Great extension, but lately with the last couple revisions to Firefox, sometimes on sites the extension previously worked on it will only load one page, instead of all the pages.
Twisting the Hellmouth, Spacebattles, Sufficient Velocity, and Questionable Questing are examples.
I select "load 5/10 pages" and only get the next page. "Load All" does the same.

Works great! I archive message boards to offline HTML files so it's nice to be able to combine multiple pages to a single page and export as one file.

Works great FF61 Beta....

Very useful, thank you !
