The Circleboom Mass Block Twitter (X) Extension allows you to block multiple accounts on X (formerly Twitter) in bulk, whether they’re spam followers, bots, or accounts who retweeted a specific tweet. It’s a safe, time-saving tool officially published by Circleboom Inc. on the Google Chrome Web Store.
Step 1: Visit the Chrome Web Store
- Open Google Chrome on your desktop.
- Go to the Circleboom Mass Block Twitter (X) Extension page.
- Make sure the extension is published by Circleboom Inc. to ensure authenticity and account safety.
🔒 Tip: Avoid using unverified third-party extensions. Only the official Circleboom extension is fully compatible with X’s API and safety policies.
Step 2: Add the Extension to Chrome
Click “Add to Chrome” on the extension page.

Confirm by selecting “Add Extension.”

Chrome will download and install the extension automatically.
Once installed, the Circleboom icon will appear on your Chrome toolbar, confirming it’s ready to use.
Step 3: Start Blocking Accounts
Once everything is connected:
Open Essential Toolbox > Block / Unblock Accounts > Mass Block X Accounts from your Circleboom dashboard, or open any of your follower or following lists.
Choose which accounts you want to block, for example:
- Followers or following of a specific account
- Accounts who retweeted a tweet
- Spam or bot accounts from your followers list
Select the accounts and click “Add to Mass Block List.” The list is loaded into the extension automatically.
Open the extension and click “Start.”
The extension blocks the accounts one by one within X’s activity limits to help keep your account safe. If the rate limit is reached, it pauses for 1 to 20 minutes and then continues automatically. Keep your browser open until the process is finished.

Notes
- The extension is available only for Google Chrome at this time.
- You must be logged in to both Circleboom and Twitter (X) to use it.
- Always keep your Chrome browser updated for optimal performance.
