The plugin works fine overall except it randomly opens a new tab every time it updates, begging for donations. I get it, stuff costs money to make. This is a really annoying way to ask for donations though and cheapens the experience. Other ad block plugins dont do this.

used this for a long old while, at the very least a decade, but now, not only with it being ineffective on youtube but also in general, there may be better alternatives out there like Ublock origin

Im using this addon for long time already and it worked mostly, but since a while YT can access my FF addon settings and disables this addon automatically after YT is recognizing that Adblock Plus is installed and active, so it doesn't take effect anymore-> no block functionality anymore, biggest question is, how can YT access settings on FF and change them, and also, which other settings can be accessed from outside to FF?
