Firefox search suggestions and new bookmarks disappearing

I'm on arch linux and sometimes my firefox search bar suggestions are just gone. When I type a web page that would be auto filled normally I don't get anything. This has happened to me a few days ago for the first time but I was able to restore the functionality by completely wiping my install, reinstalling, creating a new profile, disabling sync, restoring the old profile, enabling sync again and a few other steps I really don't remember anymore. This issue also does not allow me to save pages to my bookmarks anymore, no matter what I try. I really don't want to do the steps I listed above every few days so I just wanted to ask, what could possibly be the reason for this.
