Only just installed it, went through the settings and have saved a couple of pages, but it appears to do what it says on the tin.
I've found some pages will not save, however - The icon on the bar stays greyed out, and I get no action other than the page dimming when I click on the icon.
Hi! Thank you very much for your review. I'm very interested to know the pages you cannot save. If you have some time, please send me an email (you can find it on the extension page). If you prefer, you can file an issue here: https://github.com/gildas-lormeau/SingleFile/issues.
One of the best addons ever, seriously. Combine this with a junk remover such as uBlock Origin and you can archive pages as a single file WITHOUT all the junk you removed. The author suggests NOT enabling the option to remove invisible items. I prefer to get rid of them.
