When using the picture-in-picture feature, the spacebar is meant to be a keyboard shortcut to pause or continue the video. This is shown on the tooltips for the UI elements in the picture-in-picture feature, and on the keyboard shortcuts in https://support.mozilla.org/en-US/kb/about-picture-picture-firefox#w_keyboard-shortcuts

However, what actually happens when I press the spacebar key is it instead activates the last UI element to have been clicked on in the picture-in-picture.

For example, if I have last clicked the fullscreen icon to make the picture-in-picture fullscreen, pressing the spacebar will toggle the fullscreen mode, and not pause or continue the video.

I have just updated to 140.0esr (from the 128 esr series). I have letterboxing enabled but it now does not have any top margin. Is there a way to get the top margin back, so that is looks the same it did in 128? I much prefer the letterbox being centered in the window (128) instead of being squeezed to the top (140).

hi in current version of ff on a win 10 pc.

i have somewhere a fold in ff called "cars"., can anyone tell me how to locATE IT

the advice i previously got no longer works THAanks

Hi everyone,

I looked on multiple forums but can't find an answer.

I am trying to setup 2 way authentication for the Mozilla extensions account. But i can't get past the "Confirm backup authentication code" part.

I get the error:

"There was a problem confirming your backup authentication code"

Here is the codes that i got (can be public because it's expired and i left 2 of them out):

w1bycwwp6w eym2bx8yaj wh5h7c77qv s3snv0ez0x 9aveb72jw1 x8d3rzedah

So i copy just one of them, and i get the error.

• No im not copying all of them, just one
• No i don't have spaces in there
• No there is no capitals or anything in there or caps (im copy pasting).

It's very odd and i can't upload my application.

Please advice. Anyone have some idea?

Thank you in advance!

On any video player that has a gradient, it breaks when I full-screen the video, showing as solid semi-opaque bars instead of the intended gradients.

This happens on any video player I've used that has a gradient, and is most noticeable on YouTube due to the double gradient.

It displays normally when I use snipping tool, so apologies for the bad quality on the second image.

I use Ublock Origin and Dark Reader, but this behaviour doesn't change when either is disabled.

Hello, Since the update on 24 June 2025, bookmarks are displayed in black text on a black background. Is this normal? If not, how can I resolve the issue? I had set it to dark mode, but even when I switched back to light mode, nothing changed. I would appreciate help from the community or Mozilla if anyone has a website address to contact them. Have a nice day.

I had an extension that gave me access to Claude.ai. It was working quite well until this morning, when its CPU shot through the roof. I shut down its tab. I could not figure out how to restart it, and it's not in my extensions list. Was that deprecated? Is there still a direct interface to Claude.ai on Firefox?

I pulled up About:Firefox, and it informs I must restart to update it. That was news to me.

I could also (before restart), do successive Control-T presses to resurrect my Claude.ai. I will try that before restart. Could you tell me what I should look for in the Claude.ai tab, or elsewhere, if Control-T is successful? Thanks,

I cannot for the life of me figure this out. Whenever I load a website that needs location (for example, Google Maps or my province's lottery) and enable location permissions, the websites come back saying they cannot find my location.

I have refreshed Firefox, disabled all Enhanced Tracking Protection, disabled all extensions, and have even ran Firefox in Troubleshoot mode - all to no avail. Is there any way this can be fixed? These websites all work on Chrome and Edge and work on my Firefox for iPhone.

On Windows 10 22H2.

Ever since upgrading to FF 140 yesterday, there is a new icon labeled "Manage use of DRM Software" in the browser just left of the URL, which violently shakes every time I open a website that requires approval to play DRM content.

Now, I do not play any DRM content and have deactivated anything related in the settings, yet every time I open e.g. discord.com where users might embed music or videos in chat rooms (that are optional and ignored by me) that silly icon starts shaking again, which is super annoying.

Is there a way to remove it altogether, or AT LEAST disable the shaking?

After my last Windows 10 update this week, suddenly, Microsoft Family safety settings STOP Firefox from starting up! Can't start Firefox. DRASTIC! DEVASTATING So I HAD to import everything from Firefox to Edge browser, just to send this message. But I left Firefox as my default browser. I am the head my Family group in Family Safety settings.

After clicking on Firefox I get the following message from Family Safety: "You can't use Firefox because of your family safety settings, but it doesn't hurt to ask" Then there's a place to click on: ASK TO USE(Firefox)

  Before clicking on this I removed internet access to my machine. ASK TO USE is a permission FROM Microsoft that never comes if clicked on. These people have HIJACKED my ability to use Firefox.

They should be sued.
