Firefox for Android Community Forum

Error "No video with supported format and MIME type found" when trying to play video in many third-party players in FireFox Nightly. There is no such error in Firefox/Beta; everything works normally. What should I do? I don't want to switch to Firefox; it doesn't have about:config. And in Firefox Beta, there are no options "Enable Isolated Processes with Zygote Preloading (requires restart)" and "Enable Isolated Content Process (requires restart)", which prevent tabs from being loaded in the background. Nightly updates don't help.

I just deleted a part of my history, but when I opened a new tab it was suggested in the "jump back in" section, despite having been deleted and the browser being closed and re-opened. It's gone from my history, so why does firefox remember that I visited it? That's a big violation of privacy.

AS: 155.0 OS: Android 16

I need access to my Firefox browser most importantly for Amazon fresh deliveries on my Samsungs Phones homepage and currently it is only on my Samsung tablet. I do not use a desk top in tiny home and CAN'T, due to disability, use crome as have tried and it is to gaudy, bright and busy. Also my wifi is just included in my rent and down to no bars at all So I mostly depend on my own mobile plan

I am in Bogota Colombia visiting my family and want to book a flight Bogota to Santa Marta but Mozilla doesn't allow me to book in colombian pesos but in American doblarse as if I was the US at the moment.

Firefox mobile Android How to swish forward again? I go back by navigation left arrow but i can not undo it and revisit my last page so easy?

Brave uses swish to each directions but FF cant do this ?? And it jumps exactly to the last position in that URL.

.

To begin with, as there isn't an option in the drop down, I thought settings would be the best place to begin.

Hi,

 I'm curious if there is an avenue to customize FF, first for desktop and maybe the mobile,  and possibly even enterprise if accepted, via source. If it is possible, where exactly can I find the code? This is a preliminary question and I do plan to check git. The reason I'm starting here, one may ask of me. The answer is simple enough, like any other enthusiast dev, time is a resource best spent doing something you enjoy. So, where better to ask than the experts and community who may have a link on speed dial. 

Thank you all for any help!

Issue description

Firefox keep self logging me out from the synchronization. This requires urgent fixing.

Expected result after fixing

Firefox should never (unconditionally) self logout the user from any devices and services (with includes synchronization

Proposed enchancement

Firefox should allow to be simously logged into services (like sync) from multiple authorized devices in same time, instead beeing selective

The "x" in the search bar is a very stupid choice placement. That's commonly the place for the send button. typing an inquiry only to have in deleted is a very frustrating experience. That button needs to be relocated or have a confirmation message. Can that be modified? Thanks.

It is not a problem, but I would like to know why did my Firefox app (phone) change its logo and name to "Firefox Preview". Was it me that accidentally activated it?

Thanks!
