New

New filtering ability to remove specific response headers from document resources. Example:

example.com##^responseheader(refresh)

Only the following response headers are allowed to be removed, anything else will cause the filter to be invalid and discarded:

• location
• refresh
• report-to
• set-cookie

Chromium-based browsers

Google's FLoC is defused by default. Websites will be able to use the FLoC API (only if already present), but will be unable to get a result from it -- uBO causes the API to always fail as if there was no FLoC data available.

If your Chromium-based browser supports the FLoC API, this is the result you should get with uBO when testing with EFF's "Am I FLoCed?" (assuming you did not disable uBO's "uBlock filters -- Privacy" list):

Additionally, uBO causes all websites to opt-out of being part of FLoC calculation by injecting the appropriate response header.

You can opt-in to FLoC by creating the appropriate exception filter, see commit message for details.

Closed as fixed

• Block FLoC checks in Chrome/uBO
• json-prune doesn't remove all properties by full wildcard

New:

Ability to launch element picker into embedded frames, through a new "Block element in frame..." entry in the contextual menu.

Support for match-case filter option, but only for regex-based static network filters.

Ability to auto-complete (Ctrl-Spacebar) hostname values for origin-related options in static filter editor according to currently opened tabs.

Changes:

Dynamic filtering

Noop-ing a blocked 3rd-party cell will cause uBO to immediately attempt to reload blocked stylesheets, if any. This will also occurs when the noop-ing is done through the "relax blocking mode" shortcut, in which case uBO will no longer force a reload the whole page. You can restore the previous behavior by modifying the advanced setting blockingProfiles.

Closed as fixed:

Core

• GitHub dark mode makes whole page invisible when element picker is active
• :watch-attr() stopped working (regression in 1.30.0)
• uBO should ignore redirect= directives with unrecognized redirect token
• Can't load the images
• Reverse lookup partially fails for a filter redirecting to empty media resource
• Add AdGuard's "$removeparam" as an alias for "$queryprune"
• Network error entries in the logger are no longer colored in red
• Support parsing "Homepage:" list header for custom lists
• Please change the dashboard icon to a gear
• Improve source & destination sorting in "My rules" settings pane
• uBO badge counter doesn't work when network requests originate from service-workers
• Convert "$rewrite=abp-resource" into "$redirect"
• Migrate icons to FontAwesome svg files (from the font file)
• Element picker works incorrectly on mail.com

Notable commits without an entry in the issue tracker

• Fix case of scriptlet injection not working in about: frames
• Add new scriptlet: no-fetch-if
• Add support for match-case option; fine-tune behavior of redirect=
• Add support to auto-complete values of domain lists
• Improve representation of modifier filters in logger

This minor release benefits Chromium-based browsers. Chromium 87 added the long time missing tabs.removeCSS() API, which uBO uses:

• To enable the real-time toggling of cosmetic filters through the no-cosmetic-filtering switch;
• To enable visualization of hidden elements in DOM inspector.

But the call to tabs.removeCSS() was still failing in uBO due to Chromium being more strict regarding the arguments passed to the API.

Closed as fixed:

• tabs.removeCSS does not work as expected in Chromium 87

Commit with no entry in issue tracker:

• Fix handling of no-longer-existing port condition

Notes

The format of compiled filter lists has changed, this means that when you will be updated to 1.31.0, uBO will have to parse and compile all your enabled filter lists, which may cause larger than usual delay at first launch following update to 1.31.0. This is a one time event.

New:

Click-to-load

Support to replace embedded frames with a click-to-load widget. Examples of usage:

||youtube.com/embed/$3p,frame,redirect=click2load.html
||scribd.com/embeds/$3p,frame,redirect=click2load.html
||player.vimeo.com/video/$3p,frame,redirect=click2load.html

Result:

Users of medium mode can experiment with a redirect rule to reveal embedded frames in a page:

*$3p,frame,redirect-rule=click2load.html

Or if you want to have click-to-load only for embedded widgets from specific origins being blocked (reminder: redirect-rule does not create a block filter):

 ||youtube.com/embed/$3p,frame,redirect-rule=click2load.html

Changes:

Resources redirected to local, neutered versions will no longer be collapsed as would occur if those resources were only blocked. This change is to enable implementation of the new click-to-load feature.

Cloud storage compression is now enabled by default.

Interactivity for the no-large-media-elements switch has been improved. Notably, when the switch is enabled, uBO will try to stop playback of blob:-based media elements.

Closed as fixed:

Firefox for Android

• Unable to scroll down to the last line in My Filters pane on Firefox for Android

Core

• Implement $queryprune parameter
• Calling callback if provided for google analytics mock
• Redirection syntax issue
• Use user styles to collapse the placeholder of blocked resources
• Make load-on-demand smarter for blocked large media elements
