How to block the full screen function permanently at the same time that all menus are hidden, invisible, when you press the full screen button so that the video one gives a larger image without giving full screen. I have previously found a firefox program that could do that, but unfortunately I got it deleted.

Want to use the solution on a Win 10 PC, desktop PC and a screen of 1.5 m, i.e. 2 screens in one.

When I open the application it loads as a small window that I have to maximize to make it full screen. It never used to do this so I need some help to fix this. I've taken a quick look through settings etc and can't see anything wrong...

Hello!

I would like to develop an application that runs continuously, say, at a panel found in a kiosk. I am considering designing it as a webpage that runs locally through the browser but I would like to prevent the users from interacting with the OS or closing the tab and the browser. Is there a way to lock Firefox in full screen and hide the exit buttons? Alternatively, do you have another recommendation for development that is more appropriate, for instance a native app?

Thank you in advance for your help.

My system broke during an update. Now I want to import my old Firefox userdata, but everytime I try to use the old data firefox just forces the creation of a new profile?

Is it completely impossible to recover data not created with the same firefox version?

As a Chinese user, I am very dissatisfied with the inability to use the translation function. I request to add a Chinese option to the Firefox translation package. Thank you!

How to SWITCH TO TAB when i enter something in address bar and I have this page opened? When I search my question, I get answers like "how to DISABLE...", but I need to ENABLE this feature. Firefox 122. When I type in Address bar something like "google.com" and I already have opened this site in another tab, I want FF to switch this tab instead open a new tab/window. How can I ENABLE this feature?

While hovering over a Youtube video it shows the full video title as "hover text" if the tab is focused. However, if something else, even another Firefox window is focused hovering no longer shows anything. Is there some kind of setting to change that? I figured it could be browser and Youtube specific because Chrome shows it on Youtube even when not focused, but neither browser shows it on Google search for example, but I'm not sure.

The latest version of Firefox I have keeps making changes to my computer every time I open the program. I have to approve the changes each time, why is the program suddenly doing this? What does it have to change on my hard drive? I don't like programs making changes to my computer when they open they are usually not to my benefit and add clutter to my computer. Please answer, so far no replies to any of my questions!!

I want to navigate on search results using the keyboard. I could use tab but it suggests all interactive elements such as news, images, books, videos, search settings and etc one by one. I want to press something and make active first result, then second. If such hotkeys are not provided, maybe there are any extensions with similar functionality?

I currently run MS10. I do not like MS software but use its OS. I do not want to use MS11 when MS10 is no longer provided with security upgrades by microsoft. Will Mozilla Firefox browser run without problems on either Linux or ChromeOSFlex? If so, which OS is recommended by this community?

Example of what i want to do:

I'm browsing Website and i click and open a link. Examples:

https://Website.com/P/-this-site-doesnt-exist--68290.html or https://Website.com/P/-this-is-also-an-example--34846.html

I want Firefox to automatically delete "-this-site-doesnt-exist-" or "-this-is-also-an-example-" whenever i open any of them. So opening them would instead open:

https://Website.com/P/-68290.html or https://Website.com/P/-34846.html

Can this be done?

Cursor won't show when writing a letter or note. So I don't know where i stop typing? It works here but not when I open my browser to write letter?

Hello. When I open a private window and try to pin it to the taskbar, it instantly changes into the normal (non-private) Firefox icon and then only opens normal windows when I click on it. It's been like this since I reset Windows and reinstalled Firefox yesterday. I tried to reinstall it again but it still does this. Any help would be appreciated.

When I launch teams or slack from firefox on windows, I presume that a slack:// and teams:// or equivalent url is launched by the webpage.

As a developer working on Browser Picker, it would be quite handy if I could inspect these urls that gets launched, is there a way I can see the actual protocol url that got launched somewhere?
