So far, OK, but not always sure when it is working!

Seems to work good but often it does not offer ANY savings?

Works well, but could use a QoL feature: being able to turn off the auto application of codes. There are some websites that dont allow a code to be removed, and having a better code that the addon doesnt recognize overwrites my code. Its such a pain to have to toggle the addon off, restart firefox, then go back and complete my purchase - only to have to remember to turn it back on after and restart AGAIN.

I only installed this because I got a bonus on my account. I thought I would remove it soon after but it has become surprisingly useful. I'll be continuing to use it.
