Doesn't work in Firefox 140.0 since they added the ability for web pages to disable ad blockers.

Yes

It does work some, but slows down some sites horribly (Google Translate as a very popular example). Besides, it won't save the allow list, so I can't exclude any site permanently. Please fix this issue! It looks like a bug.

when i turn it off for one website, i doesn't stay off for that website
also it breaks websites
both problems were not fixed

For the last few months, Adguard automatically disables Ad blocking. It is to the point where I have to have the Settings pinned on the task bar and have the Ad block manually turned on because It auto shuts off after browser shut down or PC restart.

Top notch.

Extremely geeky. Unintuitive interface of many, many switches. Not at all clear what does what. Does not integrate (or recognise) that I already have it installed on MacOS and in Safari, so thinks it is a standalone FireFox extension. Consequently, much duplication of settings. Seems to ignore / not see MacOS Adguard settings. And with all that, it fails to actually block ads — well, I can hear them, I just can't see them, and I am forced to watch a blank screen for the duration of the hidden-but-audible adverts! So, all in all... Non-functional at best and lazily unintuitive and frustrating at worst. My view: Avoid, Avoid, Avoid!

as good or even better as uguard, but requires some basic understanding of networking to correctly set it up properly for your needs

Bloque pour l'instant les pubs sur YT, bravo.
