Firefox Community Forum

When I play a video in fullscreen, there is a strange black border that appears around the video which makes the content smaller than it would otherwise be. This border does not display in Safari or Chrome, just in Firefox. It also occurs in every media player I've tested, including YouTube and Netflix.

Annoyingly, I can't get this to show up in a screenshot. It seems like Firefox guesses the aspect ratio or resolution wrong when it puts media in fullscreen, and it has the effect of downsizing the actual interactive part of the display. Meaning, I can't move my mouse into the border area to take a screenshot of it.

I'm on an ARM Macbook running MacOS 13.5, if that matters.

Is this a bug, and/or is there a way to fix this?

Hello! I completely restarted my computer so it is functioning like new one. I managed to log in into my firefox account which I have used previously and had synchronized all data.

After connecting to my account there is no data after synchronisig - no history, no tabs, no passwords and accounts details.

Please let me know what is wrong.

Regards, Marcin

I did not invest such a large sum of money to not being able to log in My plarium . you and your [expletive] upped password word [expletive]. I invested a lot of time and money in plarium's stormfall game and I will be damn if I am going to start over because of your password [expletive]! Fix it right now or I will start using some other [expletive] up browser . You and your [expletive] up pass words can go to hell!

I've had this problem off and on for the past month or so. I've read through every related question and tried all solutions presented without any luck.

When I press the star next to the address bar it turns blue, but no bookmark is actually created. When I press the star again it remains blue. No dialogue box shows up. When I right click on the open tab I get a grayed out dialogue box. I *can* bookmark several tabs at once, but that's it.

I've tried changing the preferences in aboug:config to true/false and back again. I've renamed/deleted the favicons folders. I've restarted both firefox and my computer. I'm running in safe mode with no extensions. This happend once about a month ago and resolved itself. Now it's back and doesn't seem to be going away.

PLEASE help. I've tried all the solutions mentioned here before but nothing is helping. :(

I've been attempting to use FIDO2 w/ PIN support to log into Okta. This occurs with a pre-registered security key (Yubikey 5C NFC on most recent firmware) that has a PIN already configured. This key works on all other browsers and devices without trouble. Firefox is unresponsive to Yubikey interaction after the notice "Touch your security key to continue with <company>.okta.com" and will eventually time out if I do not cancel.

On the other hand, I can register a new security key on Okta through Firefox on this device. When I go through the registration workflow, Firefox is responsive to all interactions, allowing me to enter my PIN and complete registration.

I have been able to replicate this issue on other computers and with a different user / security key.

When I open Firefox on my Windows computer the Icon appears in the taskbar below the page, and the app is open, but not window opens and appears on my screen. I have to right click the icon in the taskbar and click the app again to get the window to appear. Can you help me find out the cause of this issue?

My Logitech Mouse(G600) hotkeys don't work when using Firefox.

Copy never works. Paste only works when I am hovering over Text Select.

Nearly all of the hotkeys that I have set, whenever pressed (including copy and paste) goes to wheel scroll icon. So I disabled autoscrolling.

I have tried a restart to no avail.

All browser settings were changed after latest Firefox update , some previous functions can no longer be changed Firefox your updates are worse than Microsoft updates Very frustrating

Hello team,

After the most recent update I have been having issues with the Youtube video playback. Upon loading a video it works fine, however once I click on the progress bar to skip to a certain point of the video, the video pauses, the progress bar tracker gets set to 0:00, the video starts buffering and I have to click 3-4 additional times on the specific time I want to skip forward to, in order for the video to even continue playing. I have restarted my PC, cleared cache and cookies, re-installed the browser and nothing works. Mind you, when trying to watch videos on either Edge or Chrome, there is no such issue and the progress bar works fine. I really do enjoy Mozilla, but if this keeps up I will have to change browsers it is bugging the hell out of me.

Looking forward to receiving any help.

Kind regards, Petar

Hi.

I just checked to see if there were an update to Firefox, for my secondary laptop. But for some reason it wants to update from "Version 115.0.3 (64-bit)" to "115.1esr".

I have never used ESR in my life, so why does it want to update to ESR?

Is this expected, or is there a problem with this? It is intentional that I use my Windows 7 64-bit laptop.

Hello,

I've been facing this problem while i try to download something from internet. I am trying to set firefox to ask me every time where to download the file. But firefox automatically downloads it on desktop and opens the file. I know i'm supposed to select "Always ask you where to save files" but I see no radio button beside the option "Save files to". I've attached a screenshot of my options menu. Is there any solution? My firefox is updated to latest version (115.0.3 64 bit)

Best Wishes!
