I have a Macbook, OS X 10.5.
After I updated my browser to Firefox 16, I got a warning, "Firefox no longer supports your operating system version and will be vulnerable to online attacks" which leads me to this page: http://support.mozilla.org/en-US/kb/firefox-no-longer-works-mac-os-x-10-5#os=mac&browser=fx16
On this page, it says BOTH Firefox 16 works and doesn't work with OS X 10.5, leaving me very confused. http://support.mozilla.org/en-US/kb/install-firefox-mac#os=mac&browser=fx16
I would like to have a secure version of Firefox without having to switch browsers or buy a new computer. Should I restore Firefox 15? Or is there something I should look out for?
Firefox 16 versions still work with your OS X 10.5 operating system, but that is the last version that will work.
Firefox 17 will require OS X 10.6 and later.
You can see the Firefox 17 (currently in beta) system requirements here:
So there is no security compromise for using Firefox 16?
By the time Firefox 17 comes out I'll hopefully have a new computer. Just wanted to make sure that while I'm still using my macbook I still have the full browsing experience.
Firefox 16 fully works on your computer and there is no problem with the security in using Firefox 16.
You can use that version without compromising anything.
