## Description

AdBlock for Firefox brings the trusted ad blocking experience to Mozilla's browser, now used by over 40 million users for Chrome and Safari. It blocks all advertisements by default—including video ads on popular sites like YouTube, Facebook, and Hulu—resulting in faster browsing and saved bandwidth since most ads aren't downloaded at all.

This extension supports customizable filter lists, in-page ad reporting, and quick enabling of ads on favorite sites or entire domains. Available in 30+ languages, AdBlock allows you to personalize your browsing by easily toggling ads on pages like Google search results if you prefer text ads. Enjoy a cleaner, faster, and more private browsing experience with AdBlock for Firefox.

- Generally performs well when it is functioning and has positive user sentiment.

### Cons

- Intrusive donation prompts and new-tab hijacking.
- Inconsistent blocking on major sites (e.g., YouTube, Twitch) and not blocking all ads.
- Privacy concerns / shady reputation of the company.
- No Android version / not available on Android.
- Difficulty reporting issues / lack of easy bug reporting.
