Google’s Chrome Browser Update Causes Issues with uBlock Origin
Google’s recent Chrome browser update has caused a stir among users of the popular uBlock Origin extension. The update, which introduced Manifest V3, a new set of rules for browser extensions, has raised concerns about the future of uBlock Origin.
What is Manifest V3?
Manifest V3 is a new set of rules for browser extensions that aims to improve security and performance. However, as we will see, this comes at the cost of features and functionality for some extensions.
The Impact on uBlock Origin
| Extension | Status |
| — | — |
| uBlock Origin | Deprecated |
| uBlock Origin Lite | Compatible |
Why is uBlock Origin Being Flagged?
The uBlock Origin developers explain that the issue is due to the fact that uBlock Origin is a Manifest V2 extension, which is no longer supported by Chrome. The Chrome team, however, has promised to support Manifest V2 extensions for enterprise customers until 2025.
| Year | Manifest V2 Support |
| — | — |
| 2021 | Deprecation announced |
| 2025 | Support ends for all users (except enterprise customers) |
This raises questions about the future of uBlock Origin and whether users will need to switch to alternative extensions in order to continue using their favorite ad blocker.
uBlock Origin Developer Recommends Switching to uBlock Lite
The developer of uBlock Origin, Raymond Hill, has recommended that users switch to the new uBlock Origin Lite extension, which is compatible with Chrome’s Manifest V3. This decision comes as a result of the deprecation of uBlock Origin, a popular ad blocker, due to Chrome’s new extension policies.
About uBlock Origin Lite
uBlock Origin Lite is a “pared-down” version of the original uBlock Origin extension, specifically designed to work with Chrome’s Manifest V3. While it lacks some features of the original extension, it still offers reliable and efficient ad blocking capabilities.

Manifest V3 Limits on Browser Extensions
Manifest V3, the new extension model introduced by Chrome, brings significant changes to the way browser extensions are developed and interact with web pages. However, this new model also imposes severe limitations on browser extensions, specifically content blockers like uBlock Origin.
The Key Challenges of Manifest V3
Some of the key challenges posed by Manifest V3 include:
* **New Content Security Policy (CSP)**: Manifest V3 introduces a new Content Security Policy (CSP) that restricts how extensions interact with web pages.
* **Lack of Access to Web Request and Response**: Manifest V3 requires extensions to have explicit permission to access web requests and responses, which can be difficult to obtain.
* **Limitations on Blocking and Filtering**: Manifest V3 imposes significant limitations on an extension’s ability to block and filter content.
| Function | Manifest V2 | Manifest V3 |
| — | — | — |
| Content Blocking | Allowed | Restricted |
| Web Request and Response Access | Allowed | Limited |
| Filtering | Allowed | Restricted |
The Impact on Browser Extensions
* **Redesign their architecture**: To accommodate the new Manifest V3 model
* **Rethink their approach to content blocking**: To work within the new restrictions
* **Sacrifice features**: To maintain compatibility with the Manifest V3 model
The transition to Manifest V3 will require browser extension developers to rethink their approach to content blocking and filter rules. While some developers will adapt quickly, others may find it challenging to meet the new requirements.
Why Manifest V3 Presents a Problem for uBlock Origin
uBlock Origin has been a popular ad blocker for years, but Google’s introduction of Manifest V3 presents a significant challenge for the extension’s developers. The new extension model imposes severe limitations on browser extensions, making it difficult for uBlock Origin to function as intended.
The Reason Behind the Challenge
The main reason behind the challenge posed by Manifest V3 is the way it restricts access to web requests and responses. This makes it difficult for uBlock Origin to block ads effectively, as the extension requires access to the raw data of web requests to identify and block ad-serving code.
| uBlock Origin’s Functionality | Manifest V2 | Manifest V3 |
| — | — | — |
| Web Request Access | Allowed | Restricted |
| Response Access | Allowed | Restricted |

* **Sacrifice features**: To maintain compatibility with the Manifest V3 model
* **Adapt to new requirements**: To ensure the extension remains effective in blocking ads
Alternative Solutions
While uBlock Origin’s developers are working on adapting to the new requirements imposed by Manifest V3, alternative solutions are being explored. uBlock Origin Lite, for example, is a new extension that is compatible with Manifest V3 and offers similar functionality to the original extension.
| Solution | Compatibility | Functionality |
| — | — | — |
| uBlock Origin Lite | Manifest V3 | Limited ad blocking |
| uBlock Origin | Manifest V2 | Effective ad blocking |
The introduction of Manifest V3 has significant implications for browser extensions like uBlock Origin, and the extension’s developers will need to adapt quickly to ensure the extension remains effective in blocking ads.
