Way over zealous. It blocks entry to client portals.

最新バージョン 1.45.0にバグあり
バージョン 1.44.4からバージョン 1.45.0にアップデートしたところYahoo!JAPANの広告が一部復活し、MyFilterに何度追加してもブロックできなくなったため、削除してバージョン 1.44.4に戻して使用中。問題なく機能しています。このアドオンの自動更新の停止を推奨。バージョン1.45.0の次のバージョンに期待。

Used to be great but degraded to useless. When I began to use it years ago it worked and actually blocked elements. Now, I block an element, but it comes back. I re-block it, and it comes back. I reload the page, and it is gone... until I re-visit the page by normal browsing, and the element appears again. And I am specifically not talking about elements with randomly-generated name/ID tags! I am talking about the exact same element with the same ID.
This addon has become infuriating: it does not block that which I want blocked but it blocks that I want to not be blocked. It is an unmanageable mess now. I have to turn it off completely on Monster, LinkedIn, and a growing list of sites because it completely breaks them, without any blocking set up for them.
This and the lack of wilcards! Wildcards in Javascript DOM regex CSS whatever format that require programming language skills do not cut it! We are not programmers - we are ordinary people bombarded with deluge of spam ads. We want these ads gone, with reasonable effort. If we are required to write CSS regex to get rid of an annoyance then why do you develop this software???

I've been using this a long time and it worked great....well maybe. Maybe it was causing my issues I had with FF. But one thing that continued to get worse, it won't let you turn it off. Not without a battle. You turn it off and it will turn itself back on. When it first started it would only take like twice to get it off, but now it took a good 10-15 tries to get it to stay off. I'm about to say goodbye this add-on.

uBlock Origin works, but when I watch videos on YouTube they keep loading, I deactivate the blocker and the videos are seen again, I only have this inconvenience with Mozilla, since with the other browsers such as Opera, Brave and Chrome it works correctly.
I hope they can solve it soon, greetings.

It is strange i hide video on You-tube, yet this ext. blocks me from telling me why? i wanna tell them cause they keep repeating Video in list. TY

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.

Use to like it. Now interferes with Gmail loading content.

Increasingly ineffective, especially in terms of blocking Google ads.
