Is there a good browser extension for archiving pages in one click? Firefox.

There's https://warcreate.com/, but it's for Chrome. I don't know details of it, but aren't both browsers use the same API for extensions? Then probably it's possible to port it, or to install right away.

It creates .warc files, which are supported by Internet Archive. I don't know if it integrates uploaded .warc files to Wayback Machine, but Archive Team uses this format to upload manually archived sites to Internet Archive.

I do not know about submitting to archive.org, but i use Save Page WE for Firefox to make full local copies of sites (it essentially takes the current DOM state and inlines all external files/dependencies to a single HTML file and then prompts you to save that file which can be opened later):

Thanks for the suggestion. You might be interested in Zotero [0] for a more general solution. It supports saving to HTML, saving to PDF, etc. and allows you to organize everything with tags.
