Una soluzione sembra essere cambiare user agent.
1. In the Firefox address bar, type: about
:config
2. Search for: general.useragent.override
3. Select "String" and then the + button
4. Copy and Paste this into the field:
Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:125.0) AppleWebKit Gecko/20100101 Firefox/125.0
5. Click the Checkmark Blue button to save. You're done.
6. Now Bookmark this setting so you can delete it when this issue is fixed!
