Malwarebytes Browser Guard Beta for Manifest V3

Recommended Posts

  • Staff


Malwarebytes would like to announce that we have released a beta build of our Browser Guard extension which supports the Manifest v3 requirements set forth from Google.  While we don’t necessarily align with the requirement changes we are committed to supporting our customers as best we can.

The rules included with extensions were divided by Manifest V3 into static (built-in) and dynamic rules and their number is drastically limited. 

For static rules, the minimum guaranteed limit is 30,000 rules per extension and a total limit of 330,000 rules for all extensions installed by a single user. The challenge is that one extension could use the entire allowed number of rules.

For dynamic rules there is a much smaller limit of 5,000 rules.

The current versions of Browser Guard rely on millions of rules.  Regardless of the challenges in the smaller rulesets, we want to provide an excellent experience for you!

If either limit is encountered we will present a message advising.  


To use our Beta version of Browser Guard please follow these steps:

  1. Disable the current version
    1. Right click on the extension icon in your address bar
    2. Click “Manage Extension”
    3. Toggle off
  2. Enable the beta version
    1. Navigate to https://chrome.google.com/webstore/detail/malwarebytes-browser-guar/bdnmbmckbekibamnoenjkgmllboffdca
    2. Click “Add to Chrome”
    3. Follow any install instructions

If you encounter an issue or have a question please share that feedback within this Forum area as a new topic.

We sincerely appreciate your support!
