Can I download an older version for Mac OS 10.10.5? If so, where do I find it?
I recently tried updating Firefox but the new version is not compatible with my Mac OS 10.10.5. Can I dowload an older version? if so, where do I find it?
Hmm, I guess the support article does not have the link. (Firefox Mac OS X 10.9, 10.10 and 10.11 users move to Extended Support Release)
You can download the last Extended Support Release of Firefox 78 from the following server. This address is for U.S. English. if you prefer a different language/locale, click the .. button to return to the page with all the locale links, then click into the one you want.
For more general reference, see: How to download and install Firefox on Mac.
Please be careful when trashing any unwanted version NOT to remove your data.
