It no longer remembers my blocks. I have to redo them every time I visit the same sites.

If "block element" is activated, I will expect that remains open for add many elements. It's not a good taste that I must to open the addon one time and other in the same tab, one for each element. App would be remains open until I check a switch when I finished of select all elements to be blocked on that page
