I want to develop a browser extension to save the text of all submitted revisions to the local machine.
So for example, suppose you are editing a wiki and you click "save". Your browser would then save a copy of that revision on your hard drive. Then you would have all those submissions saved as backups, which could be helpful if your article were to be deleted or if the wiki were to go down.
There's a problem on the Internet in general, which is that when sites go down, the content is often irretrievably lost because no one archived it. This could be a way to help fight against that, by making it easier for authors to keep copies at least of their own work (which is probably some of the content they care most about and would be most interested in salvaging and reposting elsewhere).
I'm thinking this should probably be a Firefox and/or Brave extension, since those browsers seem the most compatible with MediaWiki. Any suggestions on what's the best way to go about this? Do you know of any other browser extensions/plugins I might be able to cannibalize or use as inspiration for this? Thanks.
