Firefox says I'm using an old version (42.0), but when I download the most recent version I get a message that say I'm about to replace a newer version.

Firefox no longer updates my version automatically (it used to!). Now I get a message that says I don't have the system permission required to install it (what??) and when I try to do it manually, I get a message that I am about to replace a newer version of Firefox and do I want to continue. About Firefox says I'm on 42.0, but I believe that 43.0 is available. I tried to upload a screenshot of the full message, but it was taking forever (I waited 10 minutes) so I posted this before it finished).

Hello JaneOP, try the next please, download and install firefox from the next official site, do the next steps:

1. Download a copy of the latest firefox from http://www.mozilla.org/en-US/firefox/all.html (full dmg package)

2. Trash the current Firefox application to do a clean install.

3. Install the version that you have downloaded.
