The pop-up on websites in the corner is annoying, and there's no way to deactivate it permanently. You can only turn it off for the current session. This is frustrating on certain types of sites, such as those offering a subscription, because you have to manually deactivate it every time.

Avoid this kind of useless shop-savings extensions that in facts can spy what you are looking on the internet, it's just collecting informations on you to profile you and similar customers to finally target ads/products/services. That's desguished spyware in counterpart to provide you a pretended nice service for free.

And just about the service provided: this kind of extensions (lots of similar exist like this one) can modify the webpages on-the-fly and also can censure some parts or search results to guide you to buy to a specific shop... instead of a concurrent. And guess who is paying the extension editor to do that? Sellers?
Just look at what this extension is requiring at the Permissions part...

Mind again before adding browser extensions!

Saved me more money than Honey ever did 👌
Conflicts with adblock, but Rakuten.ca is all that's needed; no need to disable for other sites or to turn off Firefox privacy tracking.

As of September 2020 this is broken. It keeps asking me to log on but if I click to log-on it brings me to the Rakuten website where I am logged on I go back to the shopping site where I get asked again to log-on by Rakuten and so on and so on.....

When it worked before it was great. But currently it's useless.

A great addition to Rakuten.ca. It lets me know what sites offer cashback and i can activate cash back with one click. I didn't even think they could make getting cash back any easier than before, but now its even easier.

Next to useless with UBlock Origin installed. It barks that I have to add the following to UBlock Origin

: "Ebates Cash Back Shopping"
https://www.rakuten.ca/static/cashback-shopping-whitelist?

Which I do. UBlock origin even has Rakuten's Cash Back Shopping filter lists installed yet it continues to complain when I go to say ebay. About to ditch this add on altogether.

The WORST addon I have ever used. Either it's running a miner in the background, or the programmers simply suck at their jobs, whenever I have this specific addon enabled, my Firefox CPU usage jumps to 80+%. No other addon does this. The instant I disable this addon, the usage drops back to the usual 0-5% idle.

If you use eBates, make sure you keep this addon disabled when you aren't using it. I have notified customer support but they didn't care at all.

I really like how Ebates reminds when a site has active coupons or cash back. It's a money saver.

I have recently been told by Ebates.ca customer service that "Some stores, like Amazon.ca, have chosen not to participate in the Button program" and therefore this is essentially a useless spyware add-on
