Example test URL: https://www.wizzair.com/en-gb/booking/select-flight/LTN/VIE/2025-12-12/null/1/0/0/null Librewolf: “Critical error”, “No flights on this date.” Firefox: showing the flight prices
The network tools shows that a couple requests fail with 429 code while returning 200 codes on Firefox.
Is there some way to fix it?

I’m using Librewolf and your link is showing me one flight at 08:40.
I see 5 requests that get blocked by uBlockOrigin but no requests that return errors.
Thanks a lot for your help! Thanks to your insights, I’ve double-checked and indeed it seems that I am dumb, the issue is CanvasBlocker extension, not Librewolf itself. Sorry for wasting your time, have a nice day man!
