The final push to start using Firefox over Chrome on Android might finally be thanks to the enormous selection of add-ons (Firefox’s version of extensions) coming out next month. Chrome doesn’t offer native support for extensions in its mobile app. Also, better security.
loading the desktop version of a sits is not Firefox’s fault. It depends on the web devs.
Works fine on other browsers though. Not techy enough to say if your wrong or right, but the experience I have on a Tab s8 ultra is that ‘desktop’ versions are all zoomed in looking on FF.
