Pencu Ndimabu Firefox

Hello,

The last few days, I've been having issues printing with the built-in PDF viewer, but only on eBay. The invoices and labels will look fine in the preview, but when printed, any images on them will come out garbled and corrupted.

I tried to print using Chrome and had no issues. Would this be just a Firefox issue, or an issue with eBay and Firefox.

Any help would be appreciated! Thanks

I reset my privacy settings to "standard", as they were causing too many problems. I quit Firefox. Some websites (like Google) are still telling me that cookies are disabled, when they are not and don't allow me to go to these websites. I attached 2 screen captures. Any reason for this and how to fix this problem?

Thanks.

I recently closed and re-opened Firefox to refresh it. Now, when I download an attachment from Gmail, a pop up appears next to my downloads icon. How do I turn that off?

My old 2009 MacBook Pro broke, got fixed, and now the backup won't transfer. So I need a new Firefox.

OS X El Capitan V10.11.6 is the latest this old computer will handle. On the mozilla.org download page, the app on the .dmg that gets downloaded says it wants OS X 10.12 or later.

I'd appreciate your suggestions.
