Every time I install AdBlock Plus it stops working within 8 - 10 days. What do I have to do to keep this working? Pay for a supposedly free application? There is nothing wrong with my Firefox profile. I'm using Firefox 54.0.1 (32-bit) version. If it wasn't for the fact that the ads are even more annoying than having to keep reinstalling this I'd get rid of it permanently. Can anyone help me with how to keep this working?
