My Husband recently upgraded from the previous FireFox to the New FireFox Quantum without my approval. My Mac computer is in my name! I do not like the new FireFox Quantum! I want to go back to the previous Fire Fox Browser, Can you please help me? and direct me to where I can downgrade to the latest or very last Version of Fire Fox1? Fire Fox Quantum is Buggy, it is SLOW, I can Not select the URL Box and copy and Paste the URL, I can not open a new Tab! and I think sometimes it affects My OS? I want to get Rid of IT!

Install Older Version Of Firefox {web link} Be sure to read everything here.

If you still want to downgrade, look under; I still want to downgrade. Click the Directory of other versions and languages link. Look for the directory of the version that you want. But, remember that old versions may have security issues.

I downloaded Firefox 56.0.2 which is supposed to be the version before Quantum - but when I go to install it (I'm on mac) it says it is still Quantum... I don't want Quantum because I want the Amazon S3 ftp plugin again for my work.

I can't seem to find an older FF download that doesn't want to install Quantum... any ideas?

Have you tried a version before 56?

Thank you, FredMcD - I was able to trash Quantum and install 55 and now I have my S3 ftp add-on back, so thanks for following up!
