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.

Latest update is shrinking text on some websites for me too.

Last update is causing browser slow down to the point where websites are unusable.

One star because it is impossible to give them a 0.
They are a total joke, don't track sites properly and when they do the cashback never arrives, I followed some transactions for months and just check their complaint system, if you want your complaint to be looked at you have to send them a "nudge" every now and then with no guarantee that they will look into it.
I never got a single penny, the only one I got a payout they took it from me to cover £5 membership.
Absolute waste of time.
Get Honey instead of this

It works, but it's misleading and not really fit for purpose. Despite being logged into my account, it tells me I'll be getting cashback at a higher rate than what I actually will get.

It used to work but not on 60.0.1 (64-bit) anymore.
