For the last week or so all I get is "An error has occurred." when clicking the button on an Amazon product page. The same page works fine on Chrome. The other extensions I have installed are Umatrix, Ublock Origin, and Fakespot.

Support has released v 2.9.5 that successfully addresses the blank page encountered by some in v. 2.9.4.

It's a wonderful app, but the newest update broke it. The icon in the taskbar/menu is missing entirely. The app is installed, but there is no way to actually use it right now.
--- EDIT ---
it appears that the icon is in the address bar. I didn't even notice it moved. 5stars
