To reproduce:
- Go to incognito mode to make sure no extension causes the problem
- Go to the easyjet website IN French (the bug does not occur in English)
- Look for a flight including a return flight (in my case the origin was always GVA)
- Click on any 2 flights and go through the booking procedure without additional luggage
- Where you can select a seat, click “Passer les sièges”, which means you don’t want to pay for a specific seat
- A black slider appears from the right and keeps loading endlessly
Repeat the same steps in Chrome, no problem
