User Reviews

Users generally praise Advanced Profanity Filter for its effective censorship and strong customization options, including per-word replacements and the ability to extend the filter list. It is described as seamless and helpful for reading subtitles or articles when audio is muted. Repeated concerns focus on stability and performance, with reports of browser-related disabling and slower page performance on some sites. A common request is to add a highlight mode or per-word highlighting as an alternative to full censorship.

Pros

Effective profanity filtering that works well across streaming, articles, and other content.
Highly customizable: add words, modify lists, and use replacements.
Replacement feature is reliable and useful for quick censorship.
Seamless integration and generally smooth user experience.

Cons

Occasional compatibility issues: the extension can be disabled by the browser or fail to load on some Firefox versions.
Performance impact: slows down pages and causes lag on sites like YouTube.

Recent reviews

Generally I've been really loving the extension, I do have 1 suggestion though. I think for the filter modes there should be an option to allow some phrases to be censored, but some to be substituted or removed. I would love to be able to mix and match a little between things that can be substituted and things that I want outright censored.

Thank you to the developers for making this. I don't use it for 'profanity' haha but it's been invaluable for hiding words and phrases that I personally find upsetting. I really appreciate the versatility and customisation options. Using the internet has become a significantly less stressful experience for me since I added this to my browser. Thanks again.

Is Advanced Profanity Filter 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.

Advanced Profanity Filter requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.
