This addon seems to be obsolete now that Pihole v6 made its official release. The API has been rewritten for Pihole v6, so this addon no longer works. Also, the source repository on github has not seen an update for 6 years. I recommend switching to PiHole Browser Extension by badsgahhl, which has been updated to support Pihole v6 and is actively maintained.

with the latest version of pi-hole, it doesn't work anymore

Still works pretty well.
For those, who say "it stopped working suddenly": just re-enter your api key. That's it!
Just one thing i would like to change: the off-time which is pre-set to 10 minutees should be variable. I would like to set my standard off-time to 2 mins, so i don't have to change it every time i have to set my pihole off

This was an amazing plugin but it doesn't appear to work any longer and doesn't seem to be getting updated, have found "Switch for PiHole by badsgahhl" to be a good replacement.

This was an amazing extension! Both here on Firefox and on Chrome. However, over the last day or so, it simply stopped working. The icon is a bare with no status displayed as it no longer connects to the Pi-Hole server. Just a test button now. Both browsers too. :(

Not the prettiest... but doing what it promises...

After entering the API key in the addon settings: Works as expected! Although I thought time was in seconds, not in minutes... maybe change the text

works perfectly with my RasberryPi PiHole. Just need to set up API Key.

Great while it worked. Now it does nothing

works wonders. just insert the api key found in the pihole webinerface and - boom. really great work, syoder, keep it up.

just need the api key and works like a charm

Unusable.
Plugin doesn't connect to Pi-Hole.
No reaction from the devoloper.

Works as expected
