I was just told that the server for 1Blocker is in St. Petersburg, Russia. I'm going to deactivate this extension unti l learn if this is true; if it is, I don't want any Russian software running on my Mac or any devices I have. Too bad, because I really liked it. But during this war, I can't take a chance that Russia would attempt to exploit the software we run to help them in their war on Ukriane. If what I was told is not true, I'd like to be told. Assuming it is true, you should all consider deactivating this software now.

Used to be 5 star. Seems to me things went haywire with Catalina. It stopped working very well and it caused all kinds of lockups etc. I switched to Adguard and haven't looked back.

1Blocker gets the job done. Cleans up the web in Safari. Easy whitelisting of sites. Element hiding. Works very well, doesn't slow down my browsing experience. Some people need to get over the subscription model, and not use that as a basis for bad reviews. This is a solid ad blocker for macOS.
