Rated 4 out of 5 stars
I installed PDF Viewer 0.7.1 as an add-on in Waterfox 18.0.1. Adobe is not installed. I attempted to open a downloaded PDF. A Window opens asking me to select a program to read the PDF. In Browse I selected Waterfox, (You have a choice to make it the default reader). PDF pops open, quite readable. Printed nicely. Does not seem to be quite as crisp as Adobe, but at least I am for the moment free of Adobe, and the endless popups. I also searched for an IRS form using a search engine in Waterfox. When I clicked on the form at the IRS website, it pops up in the Reader. Cannot edit the form, but can read and print. I am very pleased. Adobe has been a torment. I give the viewer 4 because it seems a little less crisp, and because I cannot edit a form. Worthy product for freeThis review is for a previous version of the add-on (0.7.1.1-signed.1-signed).
