Firefox for Android Community Forum

I have been a service provider on speed optimization and most of the time do these on chrome for checking results. Now i have client website Trendy on which i have been working on. The speed results are on chrome are excellent all are 95+ but my client is from Australia and uses Firefox browser on its phone when i submitted him the work he checked that than his website is loading very slow especially the images they taking too much of time. I am clueless now why this happening as this fine my side

As the title says, I got a problem with Android version of Firefox that sometimes on some webpages it just hangs and doesn't load the page at all. While it's hanging there if i try to open extension settings it doesn't even load that, just opens blank page. Only way around it is to close tab and try again later. Sometimes i can just close tab and on next try it works, sometimes it just doesn't. I've had same issue with PC version of Firefox and it seems to be fixed after disabling HTTPS over DNS. On Android I've tried changing network.trr.mode to 5 but with no luck. Also ive tried disabling extensions and changing some options but whatever I do it just still keeps happening. Btw its a new install after years of not using Firefox, perhaps because of the same issue.
