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 !
