Ask HN: LinkedIn and Firefox

I recently updated Firefox to version 86.0 and started noticing problems with LinkedIn. Sometimes it would not load at all and I have to clear cookies and select privacy settings.

I don't know if this might be a coincidence but I have set myself on a quest of backing up my LinkedIn contacts, issues started appearing after I visited a few hundreds of my contacts.

Is it only myself experiencing those issues? There was recently lots of news about new privacy features introduced by Firefox, I wonder if LinkedIn was abusing privacy and this now bubbles up with Firefox blocking it?
