Blocks to much causing some pages not to function correctly. It prevents panorama pic on facebook from working is one issue.

2 часа не мог зайти в банк пока не догадался откл. AdBlocker. Тоже самое на некоторых страницах. Например cont.ws . Удаляю.

Doesn't block all ads. Specifically those I meant to block because they're loud and startle me. Also throws occasional ads in your face itself.

Does not block all ads.
For example:
ffmovies opens pop up ads automatically when clicking a movie, something Ublock Origin has no problem blocking automatically.

Some sites have inappropriately sized blank white spaces from where the ad was.

Slows firefox...

When it works, it works. Unfortunately it's missing crucial features, like

- undoing latest blocking action.
- listing ALL manually added filters (only shows a few dozen and then the list cuts off).
- search function for "Add Your Own Filters" in order to remove an item from the list you accidentally blocked, which means you need to completely reset the addon and start from the very beginning.
- keeps redownloading foreign language filters that I've disabled AND deleted. It's annoying.
- the Adblocker menu stays open when you click "Block Element" (whereas it should disappear automatically), and blocking box is often hindered by the annoying Selection Mode popup.

I've reported these before to the support email but was ignored. Doesn't really encourage me to donate when maker is oblivious to feedback.

It seems to make my laptop somewhat slower. I guess that is a small price to pay to not see the adds.

No bloquea los anuncios de openload.

Used your "AdBlocker"for over 9 years ! You make using my computer a Total Joy !

Good ad blocker except it gives you pop-ups advertising itself. Block those ads too!

Great add on

It blocks ads and is unobtrusive, but when enabled, there is a very noticeable and distracting flicker when loading different views in a website...

slooow! slower than adblock plus or ublock origin.

Still the best.

No whitelisting tube channels.... omg

Eliminates probably 85% of ads. THat's great. It also blasted me with a huge popup asking for a review. A subtle email would have garnered them a much better rating.

super tool
