^{Reminder: Chromium (or browsers based on) still suffer from that ugly bug which causes a big chunk of memory leak each time a user opens the popup UI of an extension. Therefore, the more you use the popup UI in Chromium, the larger the memory footprint of µBlock (or any extension really) will grow. I've already seen feedback like "doesn't have a µ memory footprint at all for me. >250MB" (for µMatrix). This is important to keep this Chromium memory leak bug in mind if you make use of dynamic filtering, as this feature requires frequent access to the popup UI.}

New:

• Element picker: ability to point-and-click to create wildcard-based network filters
  • Brought about as a result of issue #1044: "non technical user [...] doesnt know how to [create wildcard-based filters]"
  • Roughly, if you click more than one image from one web page, uBlock will derive a network filter which will apply to all the clicked images.
  • Kind of difficult to put in words, so here are videos:

Closed as fixed:

Chromium

• Blocking differrent kind of pop-ups

Firefox for Android (Fennec)

• ublock options ui doesnt fit on screen
• Blocking (off) when opening new tabs in Firefox from 3rd party apps
  • This also fixes:
  • Number of connected domains makes no sense

Firefox

• "Make use of context menu where appropriate" not enforced nor remembered
• Empty buttons in addon options
• Option buttons sometimes empty in addon properties

Core

• uBlock slow/with delay blocking ads (banners) and elements on page twitch
• Options-only filter is not working
• abp:subscribe links on adblockplus.me do not work with new uBlock install
• Cosmetic filter not working after refreshing the page
  • This was caused by an invalid cosmetic filter: custom filters from ABP were imported using plain cut & paste.
    • uBlock now support importing an ABP backup through the "Import and append" button in the "My filters" pane. This ensures proper import.
    • Additionally, uBlock will now discard invalid cosmetic filters when filter lists are compiled.
