Can somebody give me a version of firefox for my windows 7 professional (64 bit os) that actually work. I literally downloaded many versions of firefox (esr ones,normal ones) with exe and msi installers. But everyone one of then never works,sometimes it doesn't even install or sometimes it installs but gives error , sometimes it says we're sorry , sometimes it installs but doesn't open nor does it gave any error window. Im getting a headache.Please somebody help me (╥﹏╥)

I recently installed firefox on a new computer and it will not access the internet. Any access request gets the message "Hmmm. We're having trouble finding that site." We cannot connect to the server.... It says to check that fiefox has permission to access the web, but I do not know how to do that. How can I get Firefox to access the web? I do not want to have to use different browser, but will switch unless this is resolved.

Can I transfer my existing Firefox profile on the Windows 7 machine to a new installation on a new Win10Pro machine by copying the profile from the "AppData" location onto a pen drive, and then copying that into the comparable folder in the new machine.

I assume if I can I will then need to make the copied profile the default one using profile manager?

I'm trying to run Firefox ESR on on a Mac with OS 10.11.6. This page (https://support.mozilla.org/en-US/kb/firefox-mac-osx-users-esr) seems to indicate that Firefox ESR should work on a Mac with 10.11.6, but my computer says that Firefox ESR is not able to run on my Mac with 10.11.6. Any suggestions for how I can get Firefox to run on this older computer?
