I-Firefox Isithangami Sokwesekwa

Can you please instruct me how to upgrade my firefox browser Nr.78.15.0esr on my apple laptop OS X Yosemite version 10.10.5. I need to be able to use this very laptop for internet usage. Please tell me what other firefox browser could be uploaded in case the latest version cannot be uploaded on my current laptop. I am awating your answer asap. Thank you for your help!

Dragging and Dropping an image from a website to desktop for a “.jpg” file extension in Firefox 78.15.0esr (64-bit) (right click + drag to desktop) only works some of the time on a Mac Book Air. When “.jpg” saving does not work, image file is saved as a “weblog” (see image below). How can I do a permanent fix?

From my adobe account, I try to launch my web based apps so I can use the web based adobe acrobat, and the browser page opens as a blank screen only. I am on an older mac book w/ Yosemite 10.10.5 and Firefox is up to date wiht 78.15.0esr (64-bit). Please help! I need to be able to manipulate pdfs. Thank you

Our bank has notified us that we need to update our browser. We have a Mac (21.5-inch, Late 2009) with OSX Yosemite version 10.10.5. We are currently using Firefox 78.15.0 and it is up to date. Is there another version of Firefox that we can install that would be compatible with our older Mac and would allow us to access our bank? If so, how do we go about updating it. Thank you
