youtube presents errors during loading, leaving the left side panel and the youtube login menu empty, strangely when opening firefox for the first time after turning on the computer it seems to load normally but when browsing or updating the problem is present.
I don't use third-party antivirus, only the one that comes in windows 10. I suspect the firewall and windows defender itself.
I've been like this for two months. I tried updating windows 10, no changes. update firefox, no changes. reset firefox, no changes. disable firefox add-ons, no changes. reinstall firefox, no changes. private window, unchanged.
