About this Add-on
- Install uBO version 1.13.8: https://addons.mozilla.org/firefox/downloads/file/685614/ublock_origin-1.13.8-an+fx+sm+tb.xpi.
- Backup all your settings: go to the "Settings" pane in the dashboard, then click on the "Backup to file" button at the bottom.
- Re-install the most recent version of uBO from AMO.
- Restore your settings: go to the "Settings" pane in the dashboard, then click on the "Restore from file..." button at the bottom.
An efficient blocker: easy on memory and CPU footprint, and yet can load and enforce thousands more filters than other popular blockers out there.
Illustrated overview of its efficiency: https://github.com/gorhill/uBlock/wiki/uBlock-vs.-ABP:-efficiency-compared
Usage: The big power button in the popup is to permanently disable/enable uBlock for the current web site. It applies to the current web site only, it is not a global power button.
Flexible, it's more than an "ad blocker": it can also read and create filters from hosts files.
Out of the box, these lists of filters are loaded and enforced:
- Peter Lowe’s Ad server list
- Malware domains
More lists are available for you to select if you wish:
- Fanboy’s Enhanced Tracking List
- Dan Pollock’s hosts file
- hpHosts’s Ad and tracking servers
- MVPS HOSTS
- And many others
Of course, the more filters enabled, the higher the memory footprint. Yet, even after adding Fanboy's two extra lists, hpHosts’s Ad and tracking servers, uBlock Origin still has a lower memory footprint than other very popular blockers out there.
Also, be aware that selecting some of these extra lists may lead to higher likelihood of web site breakage -- especially those lists which are normally used as hosts file.
Open source with public license (GPLv3)
For users by users.
If ever you really do want to contribute something, think about the people working hard to maintain the filter lists you are using, which were made available to use by all for free.

Issues with uBO/webext? If so, then read carefully before filing any issue.
Firefox for Android 56: I have observed that the "Options" button does not appear in
about:addonswith this version of uBO (while this works fine with Nightly, quite probably because of bugzilla issue 1364945). However, unlike with Firefox for Android 55, uBO's entry in the browser menu is properly shown, so you can access the dashboard through the popup panel.
Closed as fixed:
