I would like to use the desktop version of a particular site on an iPhone (iOS 15.6).
I can confirm that many browsers do not universally force desktop view, but only do it on certain sites. That includes Chrome, Firefox, Safari, and Edge.
So far, the only browser I have found that can do this is Opera.
However, I can confirm by testing on two websites that Opera cannot upload files to an HTML "upload file" button. It launches the iOS view to select a file, and after you select one, the webpage does not receive it, and the field appears blank.
I can still try the other iOS browsers that I know of:
Tor, Brave, Insight, Aloha, and surprisingly many more available in the App Store.
Does anyone know of any iOS browser that can force desktop view universally and also supports file uploads, or generally, complete desktop-like functionality?
