Not the commenter, but…

I play tabletop RPGs (Pathfinder 2e for those care) online with some friends, and we use a website which hosts the program (forge-vtt.com).

For the life of me, I cannot get it to behave on Firefox. Maps will be pitch black while on Chrome they render perfectly. I’ve tried every permutation of browser setting and extension toggling I can think of to no avail.

I’ve hit the odd site where a menu doesn’t work the way it should, the payment form doesn’t work, overall form validation is wonky, or the captcha doesn’t work. I attribute most of these to slight nuances in javascript between browsers.

I’m a (old, grey) dev, and I’ve had to shame colleagues into testing in mobile browsers other than Chrome and Safari.

Sonys website immediately comes to mind

Trying to get my account back for my PS5 forced me to use edge for it to work at all

And then to use edge on my wife’s PC because something I have installed REALLY pisses Sony off

Oftentimes, when I use Firefox (Main browser on my phone) things just don’t render/show up. One thing I noticed was when I input my area code to find a package distribution center, and it straight up didn’t show. Iirc it relied on Google maps for showing these places.

It worked in Chrome. Not pointing any fingers, it’s just odd, is what I’m saying.

I use Firefox except for one thing: web serial. Chrome is the only browser that supports it. Luckily you only need it the when setting up an ESP32 for the first time and can do updates wirelessly.

This is the Proxmox console on any of my VMs or LXCs in Firefox. Works just peachy in any Chromium-based browser.

Today there was a page on my bank that just would not load in Firefox even though the rest of the site was fine. Switched to Chrome and it worked fine. I only use Chrome in these situations.
