Portable Firefox is the popular Mozilla Firefox web browser packaged so you can carry around with you on any portable device, USB thumb drive, iPod, portable hard drive, memory card, other. Download Firefox Focus - Browse like no one’s watching. The new Firefox Focus automatically blocks a wide range of online trackers from the moment you launch it to the second you leave it.
Firefox initially popped open a window stating that I already had another copy open and so wouldn't open. After some investigating, I found a fix and followed the steps to delete profiles - possibly the cause of the errors. (I had applied this solution once months ago and it had worked then.) Subsequent to this attempt, I was unable to open Firefox - even with the creation of new profile(s). Given the situation, I deleted Firefox entirely by dragging into Trash and emptying the trash and re-logging in. Downloaded a clean new install from the Mozilla website. Although the DMG file downloaded fine, when I attempt to copy app to Applications folder, the system hangs. So now there is no way to re-install Firefox?!
This link /post seems to reflect my condition: https://support.mozilla.org/bm/questions/1240427However at the given location on my computer, I only had a FB video plugin - even after i deleted that, there is no change, i.e. remain unable to implement a fresh new install of Firefox.
Suggestions?Thanks!RT12

p.s. Using a different computer to post this. When I get a chance, I'll go back to the one with this issue and see if I can post the 'troubleshooting information'.
