πŸ’» Help Can I somehow PERMANENTLY disable this annoying "is now full screen" feature? It's bugging and bullying me for years, often persisting until I move mouse cursor... Why can't one simply disable it? Do I really need to change browser for that to go away?

I'd recommend setting it to at least few milliseconds. Having it at 0 sometimes makes this popup not disappearing at all, forcing you to re-enable fullscreen to get rid of it. Changing it to 16 fixed this issue.

One of the first things I set when installing Firefox, along with setting the transition durations to 0 0 for a faster fullscreen switch.

How?

u/xezrunner 6h ago

Navigate to about:config with the address bar and search for full-screen:

  • full-screen-api.transition-duration.enter to 0 0
  • full-screen-api.transition-duration.leave to 0 0
  • full-screen-api.warning.timeout to 0

YOO thanks so much! I hated that fade when entering and exiting fullscreen.

u/mackrevinak 23h ago

and this is how it should be formatted in your user.js file if thats youre kind of thing

user_pref("full-screen-api.warning.timeout", 0);

Can I do a whitelist of websites where this applies? This way I get no pop up on YT, while anything else still is considered harmful and has a warning.

u/TrackerZapper 21h ago

Hey, it looks like your comment contains a URL with a ?si= tracking parameter, which platforms add for the sole purpose of tracking data about how links are shared. This means when someone clicks your link, youtu.be will know that the two users are connected. As well, since you posted it here, web crawlers can find it and associate your Reddit account with your other accounts. You can remove this parameter, and the link should work fine.

I've fixed your link for you:

It looks like you shared an AMP link. These should load faster, but AMP is controversial because of concerns over privacy and the Open Web.

Maybe check out the canonical page instead: https://youtu.be/dQw4w9WgXcQ/?amp

Most browsers do it as a security measure.

There is probably a way to disable it through about:config. Someone would know better than me though.

232

u/kbrosnan / /// 1d ago

Yes this is a security measure. The website could replace the UI and fake a website to attempt to phish the user.

I know, let's make the internet safer by annoying users which encourages them to do less safe things because most users are dumb.Β  We're never going to have nice things are we?

Smart users get phished all the time.

u/GasterIHardlyKnowHer 21h ago

Ok cool, so lock it behind a setting that clearly says "dangerous" and let the user accept the risks themselves. The people who care about this are in the minority, which means that such attacks would not be widespread viable anyway.

Or crazy idea, make it less intrusive or last shorter.

25

u/cassepipe 1d ago

It's been there for a long time and has never bothered me so this is highly subjective. If it annoys OP so much it's good that he can decides the level of risk he wants to take for himself and it's good the safer option is the default so that it's not worth it to make a scam based on this.

u/ency6171 17h ago

Do you use this complaint on those multi factor authentications during logins as well?

-8

u/ranegyr 17h ago

Damn I am astounded at the backlash I'm getting at the idea that the end user wants safety that isn't annoying. Yes 2fa is a pain in the ass sometimes and I challenge anyone who thinks it's perfect, it's not. I'm 45 years old and got 3 2fa steam messages the other day while trying to download a game. All I'm saying is think of the end user. If it becomes too cumbersome then less safe alternatives will become more prevalent to the masses. How is that a hot take?

u/ency6171 15h ago

Wasn't complaining about you complaining btw. Just checking if you were consistent or selective. I see you were consistent, which I think is fair.

I personally do think MFAs are a bit annoying as well tbh, but understand it's necessary.

remove it yourself from source code if you know how, which you probably don't even know how to compile firefox from source

As others said, it's a security feature. If you disable it, you'll be left exposed to a fake UI attack

u/1116574 1d ago

Can this be turned on/off on per domain basis? I would trust that eg. YouTube wouldn't try to phish me, while others would still have the warning?

u/Delicious-Phase-5854 14h ago

Maybe a custom script via Greasemonkey could do the trick but I don't know, really

4

u/luke_in_the_sky 🌌 Netscape Communicator 4.01 10h ago

I don't think a script can do that because Greasemonkey injects a javascript in the page. If a javascript running in the page could disable it, any website could disable it.

18

u/DerBandi 1d ago

maybe, but because everyone else is leaving it on, the probability of a fake UI attack is very low. It's a kind of herd immunity.

To get rid of this and some other annoying effects, try these.

full-screen-api.transition.timeout 0

I wish nothing but the worst upon any "developer" who sacrifices their application's usability and restricts user freedom in their own PC, in favor of catering to clueless facebook moms.

It's fine for these features to be the default, but they should come with an off-switch. Put some "turning this off is dangerous" labels on it, I don't care.

Then again, that whole user freedom thing totally died out when Mozilla made it mandatory to run signed addons only.

"But I wanna put my hand in boiling water!"

No, this is more like an oven manufacturer trying their hardest to restrict their ovens to 200F max because people might hurt themselves otherwise.

As already mentioned, Firefox gave the tech-savy folks a solution. And keep in mind: on the overwhelming majority of fields of knowledge in this world you and I are the "clueless FB moms".

u/GasterIHardlyKnowHer 12h ago

And keep in mind: on the overwhelming majority of fields of knowledge in this world you and I are the "clueless FB moms".

That's fine, I don't think my lack of chemistry knowledge is going to get me scammed. And yes, if you believe the guy cold-calling you saying your PC has a virus or you won a free iPhone, then you are clueless.

We spend a large portion of our lives using computers, I feel like this sort of thing should just be taught. Especially the basics like "the guy calling you saying you won a free iPod/saying your PC has a virus is scamming you" should be self-evident.

But I think beyond that, everyone should have the ability to at least be able to dive as deeply into their system as they want. I have seen intellectually disabled people who started out as tech-illiterate, and they became worthy of substituting for a junior-level sysadmin within a year. It follows that the average person should be able to do it in a year. If this sort of thing was formally taught in high schools then the lives of everyone involved would be nicer.

I understand that silently entering fullscreen on a page has bigger implications that common sense doesn't always protect against, but the message doesn't have to be so in-your-face about it and never ever ever ever disappear until you move your mouse, is what people are saying. They made it like that, in case people go away from their keyboard and then the website sneakily goes fullscreen with a malicious page. So they wait for user input before dismissing. I think that's crap and a user-set domain whitelist would suffice.

You should take your own advice. You continually complain that it can't be turned off when it can (as has been pointed out several times in the comments, along with instructions on how to do so), so you're adding nothing but whining falsehoods to the conversation.

u/GasterIHardlyKnowHer 16h ago

Then maybe you should open with that, and enlighten people how. Saying "yeah it's possible" doesn't help anyone in any way.

It's got nothing to do with YouTube. This message is automatically displayed on any website that makes itself full screen.

The popup is generated by the browser, not the website.

u/JustBennyLenny 13h ago

Welcome on Youtube where everything is designed and made only to harvest attention and focus for profit. such as the almost red-pink tracking bar

Invisible design elements:
* Pink ascents: Pink is known to have a psychological impact on users, influencing their emotions, behaviors, and even physical responses. By using pink, YouTube might be attempting to alter the user's psychological state, creating a more positive or engaging experience.
* Gradients and shading: Subtle color transitions can create a sense of depth, focus attention, or influence mood.
* Color temperature: The warmth or coolness of colors can evoke emotions, such as warmth for comfort or coolness for calmness.
* Micro-patterns: Tiny repeating patterns, like textures or grids, can create a sense of balance or harmony.

Subconsciously noticed elements:
* Color combinations: Certain color pairings can be more appealing or attention-grabbing than others, even if users can't quite explain why.
* Unexpected typography: Using fonts in unexpected ways, like varying sizes or mixing serif and sans-serif fonts, can create visual interest.
* Asymmetry and alignment: Breaking standard alignment rules or using intentional asymmetry can create a sense of tension or dynamism.
* Micro-movements: Subtle animations or micro-interactions can create a sense of interactivity or engagement, even if users aren't consciously aware of them.

im not sure what exactly disables it but using betterfox user.js disables that

3

u/AutoModerator 1d ago

/u/Moonfight1, we recommend not using Betterfox user.js, as it can cause difficult to diagnose issues in Firefox. If you encounter issues with Betterfox, ask questions on their issues page. They can help you better than most members of r/firefox, as they are the people developing the repository. Good luck!
