TL;DR
Awesome! It works *most* of the time when I need to enter a Google Search captcha while using a VPN.

My one time Buster repeatedly failed the audio captcha, I just closed the tab and opened a new tab and the search/captcha solved no problem!

THe steps are: use a VPN that Google does not like, try to do a Google Search, get challenged, check the "Select all images..." box and the pop-up happens, I click the orange human icon with a green check at the bottom to the left of the big blue VERIFY button, a new pop up happens that has a PLAY button on top. On my first test I had to click the PLAY button and it solved it fine! My second test has the PLAY button pop up auto solve and close without a click! Both times I was forwarded on successfully after the ad ons PLAY pop up closed. A third test kept failing when Buster checks the audio so I re-opened a tab with my search and the new captcha solved fine!

Overall, Buster is a must have for VPN users who want to use Google Search.

Doesn't work on Pixiv

With this enabled, I can't often get over captcha. Clicking zebra crossings all over and over again. Disabled now, things are much better.

buster captcha does not work in Opera Browser, please fix this, thank you

I installed it successfully a few days ago and it worked. Today I found out it isn't installed anymore and if I try to add it nothing happens. I'm using Firefox Nightly for Android.

still works great.

IGNORE EVERYONE SAYING IT DOESN'T WORK. IT'S BECAUSE THEY ARE DUMB :)

In fact, it's actually hilarious that this thing actually works.

Non functional

Russian🇷🇺: Не добавляется это расширение😕
USA🇺🇲: This extension is not added😕

Hasn't worked at all for months now. I click the button and nothing happens. Shame, as it used to be one of my must-have extensions.
