I switched to Pale Moon, based on a Freeper recommendation in another post. It is Firefox based, but as I understand it, Firefox in open source software. Mozilla put it’s own menus and other “enhancements” around it and marketed it as Mozilla Firefox. Pale Moon does the same and claims no connection to Mozilla, etc.
My install was done in about 5 minutes, including download. Using their migration tool all my bookmarks and add-ons came over smoothly and completely.
FFiend, within Firefox I have come to depend on typing in just 2 or 3 letters of my favorite URLs. For example hot brings up hotmail, fr immediately brings up freerepublic, da drops down some “dashboards” that I use, etc. Will I lose those with a changeover to Pale Moon?
