uBlock Origin for Opera Changelog

What's new in uBlock Origin for Opera 1.57.2

Apr 10, 2024
  • This is an emergency release to fix an issue causing differential updates to fail. The issue primarily affected Firefox because of uBO's use of indexedDB prior to 1.57.0. The issue did not affect full update of filter lists even though the asset viewer would show old versions of those lists (internally uBO compiles lists and would still correctly compile from lists fetched by full updater).
  • This release also contains translation work, so I will also publish an update to Chrome Web Store despite the issue not affecting Chromium-based browsers.

New in uBlock Origin for Opera 1.22.4 (Oct 9, 2019)

  • This is an emergency fix.
  • The issue was fixed in dev build days ago, and it was originally deemed to not be a serious regression.
  • However as reported by a user on Reddit, the issue was affecting more than just the logging of cosmetic filters, it was completely breaking cosmetic filtering when the two following conditions were met:
  • uBO's own logger was opened; AND
  • Procedural cosmetic filters were injected on the page.

New in uBlock Origin for Opera 1.21.8 (Aug 19, 2019)

  • One more filter parsing issue in the logger

New in uBlock Origin for Opera 1.13.6 (Jul 12, 2017)

  • This release contains a fix for Opera browser specifically -- no point installing it on other browsers.

New in uBlock Origin for Opera 1.12.4 (Jun 22, 2017)

  • Core:
  • Improperly punycoded hostname for hostname-anchored filters with Unicode characters
  • Request: some unused resources are spuriously updated
  • Bad Fanboy server cache policy
  • This was causing uBO to use potentially severely obsolete filter lists hosted on fanboy.co.nz, or more generally putting uBO users at the mercy of flawed server caching policies.
  • Newly created filter through the element picker is ignored after quitting/launching uBO
  • GUI "gear" Blocked by Temporary Elements
  • Punycode phishing attack detection
  • Potentially ambiguous base domain names in the popup panel will be labelled Ж (a Cyrillic character), to inform the user that the domain name contains Cyrillic characters which could be confused with some ASCII characters.
  • Further reading: IDN homograph attack.
  • More longer timeout time
  • Better handling of timeout conditions for slow connections when updating filter lists.
  • Add adblock-iran filter list to regional lists

New in uBlock Origin for Opera 1.12.2 (Apr 27, 2017)

  • This stable release has been (erroneously) published as version 1.12.1 in Chrome store and Firefox AMO. No other change otherwise.
  • No code change, just a re-package with more recent filter lists to ensure uBlock Origin works out of the box with EasyPrivacy without breaking Facebook upload feature: a filter in EasyPrivacy was causing a false positive.
  • For existing installations, just force an update of EasyPrivacy:
  • I did not look into the details, but at first glance it seems the false positive appeared as a result of Facebook changing its code. It's unlikely sites such as Facebook (who would rather not encourage the use of blockers) would test their pages when using a blocker in order to ensure their site still works fine with a blocker.
