1.41.0

To install the stable build:

• Firefox: Rejected by Mozilla Add-ons Team. The reason is that I did not provide an exact link to the origin of the hsluv-0.1.0.min.js library used by uBO to implement dark theme (uBO's About page does credit the author of the library). A README has been added to 1.41.2 to disclose the exact origin of the library.

Notes

Minimum supported browser versions has been bumped up:

• Firefox 68
• Chromium 66
  • Consequently, Opera 53

New

Dark mode

Support for dark mode added to the Settings pane, under the (new) Appearance section:

The new setting can be either Auto, Light, or Dark.

In addition, there is a new setting to control the accent color used by uBO throughout its user interface:

For example, changing the accent color changes the look of the popup panel:

Behavior at browser launch

A new setting in "Filter lists" pane to control whether uBO should wait for all filter lists to be loaded before unsuspending network activity.

By default, at browser launch uBO waits for all filter lists to be loaded before unsuspending network activity so as to ensure web pages are properly filtered at launch.

The new setting allows to opt out of network activity suspension at launch, i.e. allowing web pages to load without waiting for filter lists to be fully loaded, of course at the cost of potentially not filtering properly those web pages.

Closed as fixed:

Chromium-based browsers

• Conflicted with another extension called WebRTC Protect

Notes:

Given that the format of compiled lists and selfie changed, this may cause a noticeable delay for the first launch after updating to 1.40.0 on less powerful devices. For a concrete example, in Firefox for Android I got ~7 seconds launch time after update to 1.40.0. Subsequent launches will be back to normal, for example on mobile I get ~790ms with selfie (and "uBlock filters -- Annoyances" enabled). On more powerful devices, this should be less noticeable if at all.

Closed as fixed:

• Inconsistent line-break in the support pane for Japanese environment
• Wrong description in Trusted site pane
• Update nobab
• Specific-generic cosmetic filter is not disabled by generichide
• "Your request URL is too long": problem with too many filters and the new "problem with filter lists" button
• Exceptions do not work when processing requests with long paths

Notable commits without an entry in the issue tracker

• Improve auto-completion in "My filters" editor
• Store domain= option into trie container's character buffer
• Partially bring suspendTabsUntilReady out of experimental status
• Fix potentially reporting wrong context in logger for ghide filters
• Fine-tune static network filtering engine code
• Wait for placeholders to be present (in googlesyndication_adsbygoogle.js)
• Create synthetic event for new windows created from external application
• Add window.close scriptlet
• Store regex filter pattern into bidi-trie buffer
• Ignore pointless trailing *^ in network filters
• Change compiled list format to a saner block id management
• Store generic pattern string into bidi-trie buffer
• Remove classes specialized in handling single-wildcarded patterns
• Refactoring work in static network filtering engine
• Have getAll() returns at least one neutered Tracker object

Important

Fixed security issues reported by @hackvertor, see "uBlock, I exfiltrate: exploiting ad blockers with CSS".

New

A new "Report an issue on this website" icon has been added to the popup panel, to make it easier to report filter issue to volunteers maintaining filter lists. Reporting filter issues through this new feature requires a GitHub account.

A new Support pane has been added to the dashboard, to make it easy for users to share technical information about their current uBO's configuration, and consequently make it easier for volunteers to diagnose reported issues.
