[2025 update: Recently switched over to Linux Mint, was worried I wouldn't be able to continue using AdGuard as normal since (as of yet) there is no Linux-compatible A.G. "App" / Graphical User Interface. BUT I was very happy to find that even on Linux AG continues to be awesome:

1) the browser extension still works as normal

2) the recently released AdGuard-CLI for Linux works GREAT! (Command line is a bit of a learning curve, tho)

3) even if those didn't work, I can still use AG's DNS filtering via my router. Haven't run into any issues since!]

Fantastic AdBlocker; haven't seen a YouTube ad in ages. Easy to set up & manage, only rarely encounter compatibility issues w/ site permissions & utility popups (easy fix to pause blocking, in those cases).

Very impressed with the free version, fully satisfied after purchasing the standard version (ONE-TIME PAYMENT?? No subscription, license lasts FOREVER?! Heck YES! :D )

Have it on both my & my spouse's phones, laptops, and desktop. Gamechanging.
