User Reviews

Users like the extension for timely cashback reminders and finding offers with a lightweight UI, but repeatedly report intrusive popups, unreliable cashback tracking, and UI/UX regressions after updates.

Pros

Provides timely reminders to check and claim cashback, helping savings.
Subtle, unobtrusive UI (green flag/status bar) that doesn't disrupt browsing and is easy to dismiss.
Shows which sites offer cashback and highlights good offers, making it easy to know where to shop.
Generally easy to use and delivers a positive, convenient browsing experience.

Cons

Popup UI is large and intrusive, covers content and appears on many pages.
Cashback is not reliably tracked or paid, with delays and frequent chasing for payout.
UI/UX can regress after updates, including text shrinking on sites and occasional slowdowns.

Recent reviews

Don't bother, after doing a bit of shopping and accumulating a few pounds they locked my account because one of the following reasons ????? • Having more than one account registered. • Unusual or potentially unfair activity. • Use of the site or links in ways not permitted by our terms ! I have tried to contact them but they ignore my emails.

Amazing, makes it easy to check for that little bit of cashback when ordering online. It sits quietly on the top bar of Firefox, and the popup is handy too, although I wish there was a way to turn the popup on or off.

Love this. It makes it easy to remember to check. Sits nicely on my status bar and doesn't get in the way when it pops up. Also easy to dismiss. A great little tool.

Is TopCashback UK Browser Extension Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

TopCashback UK Browser Extension requires a lot of sensitive permissions. Exercise caution before installing.
