There is a "temporary defeat" button in Pi-hole that turns it off completely for n minutes. I use it surprisingly frequently when I'm shopping for something.
Google ads can be extremely useful when you're looking for something generic. But I am happy to have Pi-hole block them 95% of the time.
I do wish I could completely turn off 'admin' in Pi-hole since I run it on my LAN. Then I'd probably bookmark the "disaable for 1 hour button".
Which is probably possible anyway, just haven't dug into it.
