facebook freezes firefox 150.0.3

On what system? etc. . . .

PC Windows 11. Updated to 151.0.3 but the issue persists.

Do you have any VPN or security software that would interfere with connections to turn off? (Any antivirus or malware/phishing protections with "safe web" or "https scanning" features?)

To rule out any addons, I'd restart into Use Troubleshoot Mode in Firefox and follow the steps to verify any impact.

No VPN or software that would interfere with connections.

Freeze means high CPU/memory loads, resources drained, slowing down the whole PC, can't switch or close tabs etc.?

Or the UI and everything is normal, snappy, just the content inside the pages is not loading… or loading very slowly… or with errors… timelines with placeholders, images loading only halfway or not at all etc.?

Only the website and firefox freezes. Have to use task manager to close firefox.

Hi, have you already tried Troubleshoot Mode as Jan suggested above?
