So I couldn’t tell you all of them because I don’t keep track of when I need to disable it and refresh to make a page work (and that’s not that big an inconvenience for me). But I used to have to travel a lot for work with strict travel caps. Working within those, I had perfected a few strategies to really get the lowest fares available. On one specific planning adventure, I found a way to book a business class flight through Air Canada’s website that took me through Europe and back across the US for the price of the standard economy fare for the same trip. Privacy Badger killed the payment flow, and I could never get that rate back. I ended up on over 30 hours of flights in economy, and I’ll never forget the refreshed faces of the business class travelers… But more seriously, that and similar situations were the only really bad ones. Many times it’s just disabling and reloading a page. But for a casual Internet user, identifying that fix might be too much.
