I've been a huge fan of ABP for so many years now, but I'm afraid our relationship is getting close to an end due to what seems to be a neverending set of frustrations caused by its latest versions. I mean, I've been using this once flawless tool to get me rid of all those pesky ads and popups, and it used to do its job amazingly well. But since Firefox changed whatever they did, which rendered ABP not working anymore, even though its compatibility with FF was fixed meanwhile, it kept on behaving oddly ever since. It's almost mid July now and the issue of showing random numbers in the addon's icon is getting increasingly frustrating. I'm seriously considering permanently switching to uBlock Origin if this problem is not fixed soon.
I mean no disrespect for the developer, as I'm a software developer myself and I know how hard a job it is to write code that just works, especially when you're doing it for free, but at the same time I don't think I can continue to be a fan of a tool that's supposed to alleviate an issue, when it's atcually defeating its purpose instead.

My setups are as follows:
ABP 3.1 / FF 61.0.1 (64-bit) / macOS High Sierra 10.13.5 / 15' MacBook Pro mid 2016
ABP 3.1 / FF 60.0.1 (64-bit) / macOS Yosemite 10.10 / 27' iMac late 2013
Filters (the same on both computers): English (EasyList) + Adblock Warning Removal List
Still keeping my hopes up and thanks for all your hard work!
