Firefox 技術支援討論區

I have installed Firefox on my android phone now that I have installed Firefox browser on my desktop. Trouble is when I run it (on my phone) it very briefly flashes black & white blocks on screen and then makes my phone reboot. I have a Samsung galaxy S4 with android 9.0 (pie) installed. Is there anything I can do to make it work?

I am trying to create a new Firefox account with it's own email to be separate from this Firefox account I am posting from. However, every time I try to follow the "sign up" buttons I get redirected to the login page where I enter what I want as the new account info and receive a "Primary email account required for sign in" The email I'm trying to use for my new account is NOT registered with Firefox and I am using a freshly installed version of the browser on a new PC so no extensions are interfering.

My title bar has a weird symbol in front of where it says Mozilla Firefox

Sort of looks like a yen symbol and the m of the Mozilla Firefox looks weird as well

Posting on mobile devices other wise would attach photo

Long time ago I had this email let's say x@yahoo.com after some years i delete and made a new one x@gmail.com. On my PC every time I try to log in it goes like this: I put my x@gmail.com i put my password and it sends me a code on the same Gmail address... Very simple right? I put my verification code in and it says wrong password for email x@YAHOO.com... WHY DOES IT CHANGE MY EMAIL FROM GMAIL TO YAHOO ? I'M LOSING MY MIND I CAN'T LOG IN ON FRESH WINDOWS INSTALL!!!! I even reinstalled Mozilla, I've cleaned everything there is too be cleaned from the browser and same stupid "feature". Whyyyyyyyy????

I saw this same issue posted on here, but I press the shift key while using the Firefox browser and what appears to be a developer menu pops up at the bottom of the page, the crappy thing is this is occuring on my laptop so my keyboard is part of the computer lol

Hello everybody!

I have to change the resolution ( xrandr --output HDMI-1 --mode 1920x1080) but FF does not resize, please could you look at the image that I have attached?

Thanks in advance!

I have been trying for hours to get Firefox to allow me to use my webcam in the browser but I have uninstalled my browser, factory reset my laptop, removed my antivirus, gone in the website to allow, tried to find a suss certificate (which I don't want to go deleting anyway because I don't want to delete the wrong thing).

If someone can help me it will be appreciated. If you are going to go into registry keys etc please be clear in your instructions how to get there and fix it because whilst I'm not novice I have autism so my understanding might not be the same as an it person. Thanks

I used to be able to copy text in a youtube comment by long tapping on the comment and then dragging the handles to select the text.

This method of selecting text no longer works with Firefox for Android. It still works with other browsers such as Opera, Duckgo and Adblock Plus for Android.
