Fastest and most effective open-source ad blocker.

The best Firefox Ad Blocker, no doubt.

1 may 2023: Until a couple of days ago it worked fine. Now it is stopping facebook from loading the most recent entries on my groups page. When I disable it facebook works fine.

PLEASE FIX:

'You are seeing this message because ad or script blocking software is interfering with this page. Disable any ad or script blocking software, then reload this page.' alerts.

Ublock was working fine for years, but for the past month or so, I've been getting above message on news sites like the daily mail!!

thank you!

Generally very pleased. Only problem, is when I click on some links, from sites I use, they get blocked. I do, however, have the option to "proceed", which helps. Sure beats the ads, that I CAN'T delete. Thanks

The greatest and most important piece of software on Earth right now. Thank you all guys for your work!!!

Still causes LONG restarts on Mac after a crash. It will take anywhere from 10-30 mins for Firefox to load any web page after a crash. I've resorted to deleting it, then reinstalling after my pages load. Even this is tricky, firefox is so slow to load, it's hard to get around the pinwheel to click the icon to remove it. It's been this way for several versions. If I restart ONLY firefox, it does take longer to reload contest, but not as long as after a system crash.

Could be my Mac is too old somehow, iMac "late 2013" on Catalina, last available update for it.

Overall, it's the best I've used hands down, works on most streaming video pages as well, paid or unpaid. Just a shame about the restart issue.
