Nice for blocking ads and other annoying stuff.

Best extension

Лучше остальных блокирует трекеры и рекламу! ( Проверил ещё 3 расширения)

Without this you can't use the net!

The best one

Absolute banger

The best ad blocker there is ! It works on most places and are very customizable. Highly recommended! 🌟

Truly excellent add-on.

However with my Firefox 115.30.0 ESR (I'm Windows 7), the add-on is not updating since version 1.67.0 ( 2025-09-15).
No error msg. suspect new incompatible Mozilla privacy safeguard.

I have the same problem with YouTube Enhancer. Author VampireChicken wrote:

Edit (2025-10-24):
I’ve identified the issue, but unfortunately it isn’t something I can fix. Starting November 3rd, 2025, developers are required to disclose data collection practices using the 'browser_specific_settings.gecko.data_collection_permissions' key in the extension manifest.

Older versions of Firefox do not support this key. For example, when testing the extension on Firefox 115.29.0 ESR, the following error appeared:

Reading manifest: Error processing browser_specific_settings.gecko: Unexpected property "data_collection_permissions"

Can you please confirm this is the same problem please. I'll try and log it with Mozilla.

Removal and install on YouTube Enhancer will give an error:
'Installation aborted because the add-on appears to be corrupt.'

(see commends before me. e.g. Firefox user 19614113).
I haven't tried this myself with uBlock though in case it won't install or I loose config data!

Best Ad blocker for Firefox. I use it since 2022 and it performs super well !

Best script filter and worst script editor ever invented. pro tip, if you want to edit your own filters on Android, double click the line number and hit delete five or six times, that will delete the text and allow you to paste in new text, don't even bother trying to edit anything it's not going to work.
