Block Distracting Websites in Firefox on Android
BlockDistraction works inside Firefox for Android, so you can block or redirect distracting websites without installing a separate blocker browser. Start free with 10 rules and add advanced controls only when you need them.
Stay in the Browser You Already Use
Many Android focus tools ask you to replace your browser or run another app continuously. BlockDistraction uses Firefox's extension support instead. Your rules are applied directly inside Firefox while the extension handles ordinary website blocking locally in the browser.
Install it from Firefox Add-ons, open BlockDistraction from Firefox's Extensions menu, and create a rule for the site or path that keeps pulling you away from what matters.
Start Simple, Then Add More Control
Precise URL Rules
Block an entire service such as YouTube or Reddit, or target a specific path such as YouTube Shorts or one subreddit.
Pro Focus Controls
Add Rule List profiles, schedules, Daily Limits, password protection, local statistics, custom Focus Sessions and Hardcore Mode.
Choose How Each Website Should Be Controlled
| Control | What it does | Good for |
|---|---|---|
| Always | Applies the rule whenever its Rule List profile is active. | Sites you do not need during a particular routine. |
| Schedule | Blocks the site only during selected days and time periods. | Work hours, study blocks, evenings, or recurring routines. |
| Daily limit | Allows visible foreground use until a daily budget is exhausted, then starts blocking. | Sites that are useful in moderation but easy to overuse. |
| Focus Session | Temporarily applies a selected Blacklist or Whitelist strategy for a fixed duration. | Immediate focused work without changing recurring rules. |
Schedule and Daily limit are alternative modes for one rule assignment. Choose the one that matches the habit you want to change. Focus Sessions operate as a temporary global override.
Separate Work, Study and Personal Rules
Pro users can organize rules into named Rule List profiles. Only one profile is active during normal blocking, so changing from Work to Personal can switch the active rules, category state, schedules and Daily Limits together.
The same website can behave differently in different profiles. Reddit could be blocked during Work, available on a 20-minute Daily Limit in Personal, and absent from Study entirely.

Blocking rules, Daily Limit progress and aggregate statistics are stored locally in the extension. BlockDistraction does not need a remote browsing log to decide whether a page should be blocked, and the Free version does not require a website account.
Optional technical analytics are separate, disabled by default, and do not include visited URLs, blocked addresses, rule contents, email addresses or license keys. See the Privacy Policy for the full details.
Frequently Asked Questions
Does BlockDistraction work on Firefox for Android?

Can I block only part of a website?
