How to whitelist a web site
I've read a couple of feedbacks of people who wish it was possible to whitelist a web site, i.e. to disable uBlock on a specific web site.
The feature is already available: it is the big power button. It serves to whitelist the current web site, and its state will be remembered next time you visit the web site.
All whitelist directives are matched against the URL address of web pages.
As of version uBlock 0.8.2.0, the whitelist directive syntax is split into three classes:
- Plain
- Complex
- Comment
Plain syntax is when using only hostname label(s), which means only the hostname portion of a URL will be taken into account. With plain syntax, the matching is performed by comparing the right-most portion of the page hostname with the whitelist directive. Wildcards are not allowed when using plain syntax.
Complex syntax occurs if and only if at least one /
appears in a whitelist directive. Optionally, the wildcard *
can be used with complex directives for more flexibility.
A comment is a line prefixed with #
. Comments are ignored by uBlock.
If no /
appears in a whitelist directive, and if the directive contains characters which are not allowed for a plain hostname, then the whitelist directive will be commented out and ignored by uBlock. This allows you to fix your directive.

Wildcards can be used at any position. However, when a wildcard is used within the hostname portion of a directive, it cannot be at the end of the hostname, and also must be at the boundary of a hostname label.

When you are facing a case where no other directive syntax work, you may use a regular expression ("regex") as a last resort solution. When a whitelist directive starts and ends with a forward slash (/
), uBO will treat the directive as a regex-based one.
Given that whitelist directives dictate where uBO should be completely disabled, be very careful with regex-based directives, you could easily mistakenly cause uBO to be disabled on more sites than you intended. Typically, only advanced users will resort to regex-based directives, and only for cases where no other syntax can do the job.
There are user scripts on Greasy Fork, for example: YouTube - whitelist channels in uBlock Origin. I can't vouch for the scripts, you will have to find out yourself whether they work.
Someone posted instructions on reddit: Any way to whitelist certain youtube channels?.
If you re-enable uBlock by clicking the whitelist button in the popup while a whitelist directive you handcrafted is in effect, your handcrafted whitelist directive will simply be commented out. This way you can bring it back to life if ever you un-whitelist by mistake.
