About this extension
Crunch Block (also searched as Block Crunch) is a light ad and pop-up blocker for every website. Pages load faster, cleaner and without tabs opening by themselves.

• Ads on every website: banners, video ads, sponsored boxes and ad trackers are blocked before they load, using public filter lists (EasyList, uBlock filters, Peter Lowe's list).
• Pop-ups and pop-unders: tabs and windows that pages open by themselves are stopped. Tabs you open yourself stay open.
• Video sites: video ads and ad boxes are removed too, on YouTube and other video sites.
• Fast: blocking runs inside the browser engine.
• Always up to date: filter lists update automatically.
• One click to turn blocking off on a site you want to support.

Crunch Block does not unlock paid content or paid features and does not bypass paywalls, logins or subscriptions.

Works in Firefox for desktop and Firefox for Android.

Free trial: 3 days with all features.
Licences: 1 year £25 · 3 years £70 · 5 years £100 · Lifetime £150. Pay by card; your licence key arrives by e-mail immediately.

Privacy: Crunch Block does not collect your browsing history or the pages you visit.
