Saving images as PNG on web browser

[zozomeister]

Hello,

I'm using Windows 10 ver 2004 and recently found out that, for some reason, if you use the "old" Edge that came bundled with Windows 10 (not the new, Chrome based one) if you right click on a picture and save it, it'll automatically save it as PNG, which is a lossless format and it's the only browser that I know of that does that

Now, I know most websites compress their images anyways, which makes saving as PNG ever better

Is there any way to force Firefox to do so? I tried looking for an extension, couldn't find any I know that sooner or later, Microsoft will force an update that'll make the new Edge take over (tried it, saves as JPG like any other browser)
