I need to udate my current version of Firefox, however, my MAC is so old that it wont run the most currnet version of Firefox. Can anyone tell me which version will run on my MAC Sierra version 10.12.6 Thank you.

I have a Mac that you are threatening not to serve any more. I read about your Extended download. If I do not download this Firefox Extended upgrade, does this mean that my Mac will not be able to browse and read web pages, etc., or will I not be able to open any URLs?

Also, I am having problems with some downloads in Acrobat not displaying the proper font type and size and kerning, but it downloads and prints those documents in the right dimensions. Is this a Firefox problem or an Acrobat problem or a computer problem?

I should mention that I am just about out of memory on this old computer and do not wish to add more downloads at this time, until I can get some memory cleared out, which might take me awhile.

I have downloaded Firefox ESR and think it has been installed on my masOS version 10.12.1 and am wondering if I can use it on this version after reading your warning about support. Perhaps I have not installed it properly as I have just used what I think was the previous version since it has all the oldsaved sites.
