Something in this is currently interfering with uBlock Origin and causing adblock detection messages to appear on certain sites which disappear once this is disabled.

Annoying popup which covers other apps and controls in the upper-right corner. Still, it is a reminder to use TCB. Half the time, unfortunately, TCB does not award the cashback anyway. If they are called on it, they take months to deal with it and shift the responsibility to the seller

OK as far as it goes but why, once logged in, does it ask the same questions about wanting cashback every time. Most anoying!

TopCashback is a pretty good site as far as the cashback amount goes. Until now it's been a hassle to go through the website to get the cashback and I'm glad they decided to add on the extension. That being said, the customer service is the worst. Recently I've had the displeasure of having to lodge a missing cashback claim, and they gave me such a runaround that it would've been better to have talked to myself. Overall, TopCashback is only good for high cashback amount. Otherwise, Rakuten is better as far as ease of use and customer service is concerned.
