Great add-on ,it really work for me to control the ads when watching something on Youtube ,Thanks!!

I love the extention, I had to uninstall it because I had too refresh Firefox, and when I reinstalled it, all I got in my screen is the beautiful background and a place to write my name that's all. I tried to reinstall again three times but it won't work anymore

Great to have this in Firefox.
I only have one issue ... the URL bar isn't empty or: "about:momentum"
It's always "moz-extension://e9782968-df34-48a7-b711-9c9bd19e209c/dashboard.html"
other than that, 10/10

Works well, and the photos are nicer to look at than the default new tab page. One issue I've found is that the address bar isn't focused when a new tab is opened (and there seems to be no setting to change this, I might be wrong though).
