I am trying to install the new extension for Mac OS below 10.14.I have Mac OS 10.13, and this laptop cannot update to any newer OS.
I received the message that Firefox is not longer supported on my OS. I tried to download the extension to fix this issue.
I got to where there is a Firefox icon with an arrow pointing to the Applications folder icon.
Now instructions. What am I supposed to do?
I am skilled in MANY things, not computer set up stuff.
ALSO - I clicked on something that seemed logical at the time. I do not recall what it was that prompted me to choose "existing" program (Firefox). or to not choose the existing program. I don't understand the process and clicked on "existing". I fear this was the wrong choice. Most web pages will not load. But if I click on the fox icon at the top of the window, it now shows a list of recently closed tabs, and if I click on the website listed on that page, the website will open.
Any assistance is appreciated.
