After the newest update (15 june 22) Ublock doesn't work on all sites, it was working before plus in some movies I see now ads (not yt) looks like is an firefox own problem the same settings with ublock origin on opera works perfect. i am thinking its time to change the browser!

is being kinda lame recently

it's easy to be detected, AdGuard may perform better than this one

Excellent extension, but problems with GMail, started late Feb/22.

The mobile version is basically useless. All settings for blocking google, facebook, website video's, popups, tracking, etc., DISAPPEAR (as in gone) next time I start the Firefox mobile browser.

Now the customized settings disappear on the desktop version as well. The developer update has ruined this app.

Increasingly ineffective, especially in terms of blocking Google ads.

2-5-25: hasn't iimproved still slow to load. same as last review
8-31-24: degraded one start. TOO SLOW. Doesn't work with some pages. SLOW to load, slow to capture, just plain SLOW. Takes forever to delete segmented ads you wind up spending all your time blocking each segment. Have recently had to reinstall never had to do that before. No way to easily report pages that don't work.
7-29-24: cannot deal with pages such as gab.com that keep changing the address of the same add. You have to keep blocking it over and over again and editing the script does no good. Too slow to load sometimes cannot load it.Sometimes too hard to select the portion you want deleted. It's still good but not as good as it used to be.


10-20-23: getting slower to load or won't load or won't show gui to delete ads. can't capture some site's ads. no way to delete all the little social widgets at the same time. just getting TOO damn slow
3-17-23: Still the best addon on the net. But always room for improvement. Slow to respond often. Doesn't work on little social media widgets because you spend more time blocking each one than it's worth: fb,and others. No way to easily report pages where it does not work. Slow to mark offending jpgs and slow to load and block them. Still a very good addon, indispensable.
12-17-22: So far I see no way to block these little social media widgits which you have to delete one by one and this takes forever. Many sites incorporate their garbage into the main page and it's difficult if not impossible to get rid of it. In short it works like 95% of the time and for 5% you have to put up with website garbage. No easy way within the program to report sites and bugs.
7-20-22: no easy way to report pages that block it's use. Some pages it will not work. Often slow to bring up the block window.
9-16-21: Still great. On some sites when you try to use the eyedropper, the popup for the script to delete the ad does not appear or appears and then immediately disappears or does not appear at all. Making it difficult to select the script that needs to be blocked. Still a great addon though.

If you don't have ublock origin, you should get it. Best add on on the market. Extremely useful in eliminating the garbage idiot admined websites throw your way. Has a learning curve but not bad. Kudos to the developer for this program, wish they'd design a web browser too. Great.

An ad popped up on youtube before a song. That is very strange indeed. Seems this extension does not work like it should.

Update your certificates already! Tired of getting a pop up from Bitdefender that it blocked a connection to github.xyz every time I use the web. Extremely frustrating!
