but the fast moving world of browser extensions made maintenance (for a non-commercial free software side project) too expensive, so the extension support became erratic, until it died completely. for a year or two i didn't use it.
but then asked asciimo if he could have a look a the extensions (since he was recently working on another extension, so had some experience), he looked at it, and rewrote the whole thing in go and fixed the extension. he even got support from nlnet/ngi0.
if you want to have your own self-hosted libre software bookmarking service for you and your community, give it a go, it's very simple, privacy respecting and most robust when it comes to snapshotting. asciimoo did a great job.
To save logged in content, you can either pass it cookies.txt with the login cookies it needs, and it works pretty well. Alternatively, you can also use the SingleFile extension to snapshot what you want and upload it in place of the automated snapshot. This is also handy because the extension allows you to remove private data prior to screenshot, such as your name or username.
I personally have cookies in place for most common social media sites that need login (twitter, reddit), and if I need to snapshot something else occasionally, I do it manually and upload it to Linkding.
Also, it is possible to configure SingleFile extension to automatically push a snapshot to a REST Form API. You can even make it do so when you bookmarks something in your browser, to achive a flow where bookmarking something in the browser saves the page via SingleFile extension and gives it to ArchiveFile.

Also, look in the SingleFile extension options, under Destination.
