Dear Mozilla support,

For a while I have the problem that when I want to watch a video fullscreen on a website e.g. youtube, inline video etc. Firefox stops and completely closes. This is only the first time when I play the video. When I re-open the browser I can continue watching the video fullscreen without any problem. I don't receive any error messages.

Attached the specs of my phone and Firefox browser.

Kind regards, Rick

Every time a youtube video is placed on landscape mode on the firefox app of my android phone it becomes a single blurred image with the audio playing as normal.

Youtube seems to work fine on other browsers and I have tried all basic fixes, like deleting cache/data/reinstalling app etc. Appreciate any help.

Edit. Okay I managed to fix the issue so I'm adding the solution here in case anyone runs into this problem. Apparantly youtube playback decided to enable "ambient mode", a feature I didn't even know existed and seems to not play well with a phones resolution.

Just click the settings gear while the video is playing in landscape (mine is on the top right) and disable the "Ambient mode" feature.

Hope this helps.

Hi Mozilla,

On Samsung One UI 6.0 devices, the Korean fonts are showing serif fonts where as other browsers are showing sans-serif fonts.

It seems when SamsungKorean font on the device changes the nameId=1 value to "SamsungKorean_v2.0" the issue is resolved and shows sans-serif font just like other browsers.

Could the issue be firefox using nameId=1 directly?

I'm trying to use Firefox on Android but it's says that I need a secure connection even though I'm just trying to Google something or go to a secure website. It also says that it's the websites fault and there's nothing I can do despite that when I tried again a half hour to few hours later it work perfectly. I don't know what's going on with this app but I would like to use it without it just stoping me from just even trying to use Google or any browser it has. Please help me fix this. I can't even go to YouTube on Firefox. Apparently it's some form of connection issue despite that If I uninstalled, then reinstalled the app it would probably work for a little bit then go back to having connection issues

"Hello Mozilla Support Community,

I'm encountering issues logging into my industrial adhesive manufacturer website using Mozilla on Android. Despite entering the correct credentials, I'm facing difficulties accessing the site.

Are there any specific settings or considerations for logging into websites, especially those related to industrial adhesive manufacturers, using Mozilla on Android? Any insights or tips from the community would be greatly appreciated.

Thank you for your assistance!"

This forum website sometimes just gets stuck and doesn't want to load, and Firefox won't even throw the timeout error. This issue cannot be consistently replicated.

I tested this in another browser called Google Chrome, and the issue is not present there.

I have a Redmi Note 11 Pro 5G running Android 13.

I'm having trouble with Bing not using the layout I want it to on my tablet. On edge, another chromium browsers, Bing will render with a nice tablet layout. But on Firefox for android on my Pixel Tablet, Bing renders a stretched out version of the smartphone page. Is there anyway that I can change the user agent so that I can make it load differently?

Is there any way to edit the autocomplete data on my address bar?

There is a site i frequently use that starts with the letter 'G', so if i want to vidit that site, I press G on the address bar, hit enter and hope that autocomplete sends me to that site, but instead it always sends me to google.com .

Normally I would let this slide, however firefox always tells me that I could search directly from the address bar instead. If that's the case, then why send me back directly into the problem?

Last night I tried to switch accounts on Facebook (webpage, not app) on Firefox on my phone and it wouldn't load. Now I can't get into it at all on Firefox. Every other website I've tried works except Facebook. I've refreshed, cleared the cache, restarted my phone and logged into FB from another browser, where it worked fine. Any ideas?
