Can PDF compatibility in browsers be improved via server-side code?

Asked this in InDesign recently, then realized I wouldn't really know for sure until I ask coders.

Exported my InDesign PDF magazine with layout setting "Two-Up (Cover)" so it displays the standalone cover, then switches to double-page view (until the back standalone cover).

There will be a standard web link to the file, so users can open it however they choose — most will use Acrobat, and have zero issues — but for the few who will open the PDF file in-browser, I noticed only Firefox seems to respect the "Two-Up (Cover)" layout setting... neither Edge, Opera or Chrome will properly display 2-page spreads natively.

My first question is, why Firefox? Is there a partnership between Adobe/Mozilla I'm unaware of, or did FF just decide to include a little more PDF compatibility than the chromium browsers have?

My second question is : could this limitation somehow be overcome by some server-side code trickery (html, css, php, js)? I assume the answer is no, but getting that confirmation from the experts would make it easier for me to move on from this curiosity.

Thanks!

PS: Not really interested in 3rd party plugins or creating a sandbox in the page to display the PDF (iframe-style). Just whether or not it's possible to "help" any of the uncooperative browsers interpret the "Two-Up (Cover)" layout via code. I find browsers display PDFs natively just fine, aside from this annoying limitation (that FF doesn't have).

EDIT: Guess not.
