It's a minor but really annoying issue that I've been facing for the past few days.
When I open Firefox for Android and load the Zorin Forum page (from a cold boot), it gets stuck while loading the page (Stuck on a blank page while the loading bar is present) - I have to reload Firefox and/or the tab to get it to load the page
I think this may be an issue with Discourse.
On Fennec (Firefox fork) it seems to work fine for me, same as with Brave.
But I used Firefox when I first joined the Forum and it seemed to work alright.
Side note: I used Brave for a little bit after that, but I went back to Firefox because I don't want the crypto stuff.
Try to clear the cache? Or maybe it's a new bug introduced due to a recent update.
That's the one I'm using right now.
Also I have the most up to date version.
I use Samsung's browser, since it is a Samsung phone, which allows me to install pages/sites as an app...
Never have a problem loading unless I don't restart my phone weekly.
