I've recently started seeing sites break, and I see random Cross-Origin Request Blocked errors in the browser console. This appears to have caused some issues on Amazon. 1 star because it breaks sites, but +1 star because it *does* do what it advertises.

Completely broke Amazon. Won't load any pages. I'll change back to 5 stars if it starts working again, but I guess I won't know if it does because I'm removing it, so...

Does the job asked for.
The sponsored article are masked.

Breaks parts of the AWS console, e.g. CloudWatch Logs.

Seems to work on Amazon. Much relieved when top items actually are relevant to what I'm searching for.

Maybe it used to, but this is not removing sponsored ads from eBay for me.

日本のAmazonにもちゃんと対応。うざったく紛らわしいだけのスポンサー広告が全てのページ/ウインドウから一気に消え、ミスクリックの発生率がゼロに。素晴らしい！

Works like a charm on amazon.de and ebay.de.
So far no issues what so ever

Comparing to this same extension on Chrome: In Firefox, I cannot for the life of me figure out how to get the icon to display, cannot modify the affiliate link permission, and cannot modify the site permissions.

This script for some reason blocks the Seller's Description for every listing on eBay. In Chrome this can be resolved by removing permission for eBay sites; In Firefox, this permission can't be accessed, which makes eBay unusable.

I've done a lot of searching and found no way to resolve this in Firefox. If there is a way I will happily update this review. Until then I can't recommend this add-on for Firefox, at least for anyone who uses eBay.

Really absolutely fantastic. Works perfectly on Amazon.com and Amazon.co.jp. Huge relief to start getting more useful results on Amazon.

What a relief, I can actually see my search results on Amazon again without the clutter, thanks to this addon. It was getting ridiculous.
