I liked ( past tense ) watching YouTube with the latest Firefox on my Mint Linux box.

No more.

The ad blocker I use ( latest version ) has stopped working for removing YouTube commercials.

The commercials are obnoxious.

I think I will quit until the ad blocker I use updates again with a fix.

Sorry YouTube, you are far from being worth $14.00 USD a month.

Edit:

Mint Linux 21.2

Cinnamon 5.8

Firefox 128.0.3

Ublock Origin 1.59.0

• I completely removed UBlock Origin
• I completely emptied my Firefox cache and other data
• I signed out of Google completely
• I reinstalled UBlock Origin
• I signed back into Google
• I tried using YouTube with my VPN turned on.

No joy.

I can watch YouTube ad free via a private window in Firefox.

I can watch YouTube ad free if I log out of my Google/YouTube account

My add blocker works in other browsers when I am not logged into my Google/YouTube account.
