Ad blocker recommendations please

[Domoda]

I know MN depends on the income from ads but there are some that I just can't cope with that spoil my use of the site...the northern rail one with the man, the movement on that makes me feel physically queasy. Hate it.
What adblocker apps (android) are ok and won't screw my phone up or cause any problems with things like log ins etc?

I thought Mumsnet guidelines say you aren't to block adverts? I'll try to find it

Here

Well of course they say that.

If there was a way that I could block the one or two adverts that make me feel queasy or annoyed when they play I would do, and put up with the rest, but there is no way to do that.

Or if anyone can tell me how to block the one or two specific ads I'll happily go without using an adblocker.
