Sponsored Ads on Facebook (in stream sponsored posts)

Yeah, that's the exact behaviour I experienced with ver: 1.1 when it was bugged for me.
The good news is, it can be un-bugged.

Un-install all add-ons (un-install, not disable).
Reboot.
Install ABP & test functionality.

That was all I needed to get ABP working properly.
I then re-installed some of the add-ons I had removed, testing ABP after each install till I found the add-on causing the bug.

Once I had identified the problem add-on I had to repeat the whole process to get ABP working again.
I dumped the bugging add-on (don't miss it) & ABP has worked properly since then. I very, very rarely see any ads or pop ups & when I do they are usually soon corrected with an auto pattern file update.

I would like to work on this... Can you assign it to me?

facebook.com##div[id^"topnews_main_stream_"] div[data-ft*="\"ei\":\""]

is the filter that seems do not working.

Now I'm investigating on this defect.

Errors on debug_result.txt :

The problem is in CPluginFilter::AddFilterElementHide and CFilterElementHide::CFilterElementHide.

Code problem is here:

while (!filterString.IsEmpty())
{
    if (filterString.GetAt(0) != chAttrStart)
    {
      DEBUG_FILTER("Filter::Error parsing selector:" + filterText + " (more data)");
      throw std::runtime_error(CStringA("Filter::Error parsing selector:" + filterText + " (more data)").GetString());
    }
...

because, first time of loop

filterString = '[id^"topnews_main_stream_"] div[data-ft*="\"ei\":\""]'

the second time

 filterString = ' div[data-ft*="\"ei\":\""]'

so filterStringGetAt(0)=' ' and chAttrStart='[' and so DEBUG_FILTER starts

[Mailkov]

The easier way to solve this defect is to substitute the filter for simpler one.

I spoke with Arthur: it is not possible to change the filter ...
So the only solution is to support it.

I tried this filter:

facebook.com##div[data-ft*="\"ei\":\""]

and it works and it have the same result of

facebook.com##div[id^"topnews_main_stream_"] div[data-ft*="\"ei\":\""]

Can we divide this into two filter? example:

facebook.com##div[id^"topnews_main_stream_"]

and

facebook.com##div[data-ft*="\"ei\":\""]

oleksandr, How about this?
