What if you export your bookmarks and your addons, then delete your profile, create a new profile and sync NOTHING from your firefox account. Then import the boomarks, restart and see if that is the issue. Then add your addons one by one and restart inbetween to see if one acts up. Then change your firefox settings. Then turn your sync back on.
Also are you using a normal installation or a flatpak, snap, etc?
Is it just bookmarks, or is it bookmarks and sync? I’d export your bookmarks as JSON or something and look through it, either with a text editor or some tool, and make sure there isn’t some enormously huge string, or one containing unsupported characters, that’s tripping something up somehow.

Import your bookmarks in sections until you hit the one malware URL that’s mining coin through the Firefox’s interface.
This is some proper troubleshooting.
