Dynamic filtering: turn off uBlock everywhere
The ability to turned off uBlock everywhere has been requested many times: #40, #403.
I wasn't really planning to provide this functionality as I fail to see why it should be implemented in uBlock when the browsers themselves offer this ability through the disabling of extensions.
In any case, the ability to "disable" uBlock everywhere is now available, as a side effect of the ability to create a global allow rule for all network requests:
Though it's more "allow everything from everywhere", it's as good as "globally turn off uBlock". You can revert it by clicking on the eraser button.
Important Addendum: The above is no longer correct. According to gorhill: "This is a suggested workaround which may and may not work depending on whether there are current dynamic rules in use, and since now there is strict blocking (wiki was written before strict blocking), strict blocking has precedence over dynamic filtering for doc request."

In other words, all sites that are filtered to block the entire domain will still not work even with this workaround when strict blocking is enabled (which is recommended).
