^{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.}

Closed as fixed:

• Workaround #1001 for Fennec breaks Google Hangout extension
• Support importing filters from an ABP backup file
