What version of ABP are you running?
I have 2.9.1 running in Seamonkey, and it's working fine for me,
although I have done some additional tweaking.
If ABP is not blocking what you expect, it may not necessarily be the
fundamental capacity, but it's likely that you want more than the
default EasyList subscription.
Although a lot of the subscription sources are language-specific,
there's a number of English-based ones that will get stuff that the
EasyList filter misses. The primary alternate I use is the adservers
list
squidblacklist.org. I also use a couple of FanBoy's additional
lists, the annoyances list (which blocks various annoying things, such
as links to social media and warnings from sites that complain about ad
blocking). I also use I Don't Care About Cookies, which mostly
suppresses alerts about cookie handling at sites in the EU.
Subscriptions apply to all versions of ABP, whether you're running the
old version in pre-Quantum implementations, or the WebExtensions version.
Additionally, I run Element Hiding Helper for AdBlock Plus, which allows
for blocking full elements on a page, rather than specific graphics.
And for some pages, I will block non-advertising content, simply because
it's stuff that I don't want to see (especially on repeated visits)
At this level, you have be prepared to do your own tuning of blocking
specific graphics or elements, but it's not difficult to do -- start
with a right-click on a graphic, and you can add a specific graphic, a
pattern of a graphic name, or with the Element Hiding Helper, even a
full element to your own personal blocking list.
If you're running a Quantum version of FF, ABP is still there, but the
UI is different enough that it takes a little getting used to. I
haven't played with this a lot, but I believe that all the functionality
is available, including that element blocking is now included in ABP
directly, rather than having to use a companion extension.
In this discussion, several have suggested uBlock Origin as an
alternate, and it works well, although IMO, it's a little harder to set
up. But uBlock also works from subscriptions (the same list as
available to ABP), and it's my suspicion that if you're using the
EasyList subscription in uBlock, you might not see results that are
significantly different, without adding additional lists, and/or doing
more personalized tuning of your configs.
