Features & Capabilities

This add-on blocks Google ads on your browser.

Most ad-blockers contain multiple files that have to run before your page loads. So it can slow down how fast your browser opens a page. Spamurai™ uses only a few lines of code in a single file. So it loads websites much faster.

Why would other ad-blockers use so many files? Because they give you the option to 'white list' certain sites. This means that you can tell their program to display ads on select websites. They also partner with larger sites (such as facebook) to allow those sites to display ads by default. This is how they make their money.

Spamurai™ just blocks everything. It doesn't track the stuff you're browsing, nor does it save any of your information. It just looks at the website's code before it loads, and removes anything labeled an 'ad'.

Thank you for your support!!!

We're still in the early stages of this project. So next we're going to make this add-on work on other ad-platforms besides Google. Google-ads make up about 85% of the ads you'll see on the internet. But we would like to close that final gap.

Also, this is a community based open-source project. So if you know how to code, and would like to contribute to fighting internet spam— look this project up on our homepage.

Is Spamurai 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.

Spamurai requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Spamurai is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
