I’d love a Firefox extension that crossposts to Lemmy whenever I upvote a Reddit post. The communities I follow on Reddit are still too niche on Lemmy. I want more of that content here but don’t want to spend the time re-posting manually.

Anyone seen an extension like this?

It’s possible to make it, I’ve made ff extensions before.

Just listen to the upvote button click, resolve the redirected url of the post, or copy the post text and submit the new post to a mapped community. Need to be logged in to lemmy .

Edit: use regex to get a valid CSRF token before posting
