TL;DR (From Android Authority)
• Mozilla responded to a review mentioning the lack of tablet UI optimization for Firefox on Android.
• Mozilla confirmed that its team is not working on optimizing the tablet experience at the moment.
• Mozilla did, however, say that it hopes to revisit tablet optimization when time and resources permit.
I maybe biased (typing from Fold 4), but this seems to be important to me, doing this makes Firefox seem like a laggard and behind the chromium world.
As a Pixel Fold owner, I agree. I switched to Firefox on desktop, but the bad unfolded interface prevents me from using it on mobile. Luckily I can use extensions with Kiwi, but I’d rather not use a Chromium browser.
Regardless, this is important.
This means that, for tablet users, the option is between Chromium on Android or WebKit on iOS, unless they’re using a Windows or Linux tablet.
