I'm following the instructions to set Firefox nightly as my default browser, but when I go to settings and try to switch the toggle to "set as default browser" instead of doing it, it just opens a new tab with the instruction. I got up to 4 identical tabs before I gave up. I know how to do it, it's just malfunctioning.

In a separate issue, I have had Firefox Beta for about a year on my Kindle Fire, always worked great. Since the latest update, it won't even open. The screen pops up for a second, then immediately closes. I uninstalled and reinstalled, same issue. I installed regular Firefox, no issue. Then I found nightly, installed with no issue (other than the problem listed above).

I have the latest version of Android 13 and Firefox up to date on my phone, but there's been some weird behavior when playing videos as of late. Videos refuse to properly go fullscreen now. When I tap the fullscreen button, the video moves to the center of the screen but stays in portrait orientation, which is obviously not what I want. In addition, picture-in-picture is not working at all, and the notification control panel (that lets you pause and play minimized videos from the notification) is not appearing even though notifications are not disabled for Firefox. Videos still play, but almost none of the features for them are working. What is going on? Can anyone help?

Briefly, when openning a link that should redirect to a WhatsApp chat, it says - after pressing open chat - WhatsApp not installed. Why? Note: In chrome it is working normally.

While browsing Amazon.com using the past several builds of the Nightly for Android, I get this most annoying bouncing pop-up tip that is a yellowish with black font saying to click on this heart icon to save the product. I have never seen this on any other browser for Android, and never on my Firefox on my laptop or desktop. Is there anyway to get rid of it? I cannot stand this and I have almost thrown my phone because of it many times. I have never thrown a phone before. I cannot explain why, but it pisses me off so very much!

Hi In the absence of network connectivity, submitting a search or entering a URL in the universal bar fails to detect the network issue. Moreover, the content of the universal bar is lost (forcing the user to type again, which can be very frustrating for a long URL)

How to reproduce: - open firefox iOS - switch your phone to airplane mode and deactivate wifi - open a new tab and try accessing any webpage (eg mozilla.org, or type something to be searched) - observe how the content of the bar is instantly lost and a blank page is displayed.

What should be expected: - the universal bar should still contain whatever was typed (or the URL of the search engine) - the body of page should display the usual "The internet connection appears to be offline" message.

PS: this apparently only happens in newly created tabs, not with existing ones.

Ok, so this question was asked 3 years ago. Is <datalist> still not working? I am only having this issue on Firefox for Android. Here is the original question I found having he same problem: https://support.mozilla.org/en-US/questions/1301131
