Good

Лучший блокировщик год использования, высшая оценка

5 stars because this is consistently good and I'm sure bugs will get fixed.

Latest now being updated based on Webextensions so that's good, will work after Firefox 57.

On Windows no major issues. Had to restore my filters from file by going back a version, taking latest backup, then installing latest and importing. Only noticeable difference is that blocked elements often load then disappear, sometimes this can take half second or so, which is annoying. Previously they wouldn't load at all.

Bigger issues on Android, seems to be broken. Add-on is on and seems to be blocking based on hosts file but can't get into change/tweak anything.

I componenti aggiuntivi consentono di aggiungere nuove caratteristiche o funzionalità a Firefox.

I'm able to see ads for a couple of hundred milliseconds when I load or reload a page.
Also, it wiped out all my filters after update.

Wegen des Problems mit dem Aktualisieren bei Ebay hatte ich uBlock vorübergehend abgeschaltet - da merkt man erstmal wieder, wieviel nervige Werbung durch uBlock weggefiltert wird ...ich möchte auf uBlock nicht verzichten :-)
Wie von Eric321 vorgeschlagen, habe ich downgrade auf 1.13.8 gemacht und hoffe, dass die Probs in 1.14.4 bald gefixt werden können.
Vielen, vielen Dank an Raymond Hill !!!

I'm running Mac Firefox ESR 52.3.0. I had many "cosmetic" custom filters created in UBlock Origin (in "the dashboard"), which were working fine. They represented hours of my work in cleaning up many websites that I visit regularly.

The update to UBO 1.14.4 completely deleted all my filters without warning! I couldn't figure out which exact file they were in so I had to restore my entire FF profile from backup.

After I got my filters back... they didn't work very well. About half of my custom filters were ignored; or they'd work when first created, but as soon as that web page reloaded, they were ignored.

On UBO's github page, I discovered that this problem was discovered, discussed, and a new bugfix version posted: 1.14.8. However Firefox warned me not to install it from github because it wasn't "verified." I installed it anyway and the problem seems to have been fixed.

I've been using UBlock for ages and was fully satisfied. Now, Firefox label this add-on obsolete and deinstall it regularly.

The difference was not 64bits vs 32bits, but request policy addon on the 64bits versions.
Even when set to let pass everything, request policy was interfering with uBlock.
uBlock is working ok now that request policy is deactivated.

When pressing on ublock origin in the drop down menu in Firefox 57.0a1 Android the page that opens shows a huge on off button and the text is large as well. I use the advanced mode and some settings is out of reach because it is too wide inside the page.
I use a Samsung galaxy tab pro 12.2 and most websites looks better in desktop mode on that screen size. So it would be great if ublock could fit in the page.
Otherwise ublock is a great addon that prevents lots of downloading of data from ads.

Just reporting that this version is indeed working with Firefox 56.0b8 (64 bit). Also, please reduce the size of the icon on the main toolbar. It was much smaller before multiprocessing.

Certainement le meilleur adblocker
Convivial et performant

Worked great until the last update. Now blocks nothing and the menu isn't accessible. Also disappears on restart of Firefox. Tried un- then reinstalling, no fix.

Usually very good. Works like a charm.

Then on the other hand. Strange hickups after automatic updates.
Right now version 1.14.8 stopped working with Firefox 56.0b8.
Deinstalling, installing. Nothing helps. The icon disapears from shortcuts bar and no settings are available. No adblocking at all.
Had to go back to version 1.13.8 (https://addons.mozilla.org/firefox/downloads/file/685614/ublock_origin-1.13.8-an+fx+sm+tb.xpi)

Any idea what might be the problem? How to solve this?

Blocks all ads effectively and does not engage in any blackmailing-like scheme in contrast to AdBlock Plus.

nice
