This release brings a streamlined user rule editor, the new Mail Tracking Protection filter, and a few quality-of-life upgrades for Chrome MV3.
Improved user rule editing
The
User rules section now uses
RulesEditor instead of Ace. The new editor has two modes:
List view, which displays your rules as a searchable list with checkboxes to quickly enable or disable individual rules, and
Editor view for direct manual editing. An overflow menu in the top-right corner gives you quick access to
Rule syntax help,
Import,
Export, and
Delete all options.
Here’s what the old rule editor looked like:
And here are the two modes —
Editor view on the left and
List view on the right — of our new editor.
The
Allowlist section now also runs on RulesEditor and has an improved overflow menu.
New Mail Tracking Protection filter
We’ve added a new
Mail Tracking Protection filter that removes tracking pixels — invisible 1x1 images that are used to tell senders when an email has been opened. These trackers can’t be blocked by domain alone, since most email services proxy images through their own servers. Instead, this filter uses other signals to catch them without breaking legitimate images.
More accurate filter update dates
Previously, the
Filters tab in MV3 settings showed the extension’s update date for all filters, no matter when the filter itself was last updated. We updated the filter metadata handling so the
Last updated field now shows the filter’s real update date.
$urltransform modifier for advanced users
For advanced filter makers, v5.5 adds support for the $urltransform modifier. It lets a rule rewrite parts of a URL — like its path or query string — before the request goes out, including redirects handled through Chrome’s MV3 declarativeNetRequest API. This makes it possible to strip tracking parameters and other unwanted bits from URLs without blocking the request entirely.
