This an interesting one. When running Firefox on my personal Macbook. I've been recently having issues loading sites like Reddit, Facebook and a few others in private browsing mode. The issue seems to only affect certain sites, browsing the rest of the internet I have no issues. However, with these sites, they simply either will not load or require multiple refreshes to work. Even more interesting, my work Macbook has a similar ecosystem and works fine. I have updated and reinstalled Firefox, cleared caches and history. And run both with and without VPN. As well as being sure to reboot the Mac before trying each new attempted fix. Does anyone have any idea what's happening or what my next steps might be before I go to Apple for help?
