Firefox Support Forum

When in fullscreen, if I move the mouse to the top-left corner and right click, a browser context menu appears. The page I'm on is using mouse right clicks, so this browser function is breaking the controls of the page if I ever accidentally click the top left corner (which I do often).

Is there any way to disable this menu appearing? I would never use this menu to minimise/close the program so I just want it gone. It's breaking fullscreen controls in it's current form

When I click on a pdf file, Firefox opens and displays the file, rather than handing it off to Acrobat, which is my preference. I'm running Firefox 122.0.1 and Windows 11 Firefox seems to ignore the settings in General, Applications. (See attached image)

    If I set to Always Ask, Firefox displays the file without asking.
    If I set to Save File, Firefox does not save the file.  It displays pdf instead.
    If I set to Windows Default Application, Firefox displays the file.  
         (Note: Acrobat is set in Windows as my default app for pdfs.  If I find a pdf with Windows Explorer and open it there, Acrobat is launched and it displays the file.  IOW I've confirmed that Acrobat is set as my default app for pdfs)
    If I set to Acrobat, Firefox displays the file.

I see nothing in Firefox Settings showing an Add-in for pdfs Any ideas?

Hi, I am trying to install an add-on for MetaCert. I receive the following from Firefox: "Check This by MetaCert by MetaCert". This does not help to install the add-on. This is not a problem on my other PC. Look forward to your help/suggestions. Best, Stephen Rodgers

hi

For several days now I have been receiving the message "Automatic activation of filters". It goes away after a few seconds but is extremely irritating, how to turn it off?

Hello, In old versions of Firefox picture-in-picture mode was "always on top" by default, now "always on top" mus to be enabled every time I pop-out every video. Is there any solution to make picture-in-picture mode "always on top" by default?

Po przeinstalowaniu systemu i wgraniu Mozilli mam problem z otwieraniem plików. Brakuje mi możliwości jak ze zdjęcia, które jest z instrukcji jak to robić. Przykładowo pliki .pdf zapisuj się i otwieraj od razu, wszystko fajnie. Ale już pliki .msg czy .eml nie chc otworzyć się automatycznie w Outlook'u i nie widzę nigdzie opcji zaznaczenia "zawsze otwieraj podobne pliki" czy jak to tam szło dokładnie. Bardzo proszę o pomoc gdyż bardzo mocno utrudnia to pracę i użytkowanie przegladarki.

Am running on linux with KDE. When I press the software shutdown button in KDE, and reboot, the tabs in firefox remain, even though I disabled that from happening in settings.

After a recent Microsoft update, FF Picture-in-picture now broken. Will not detach from viewer, instead expands much larger beyond screen. Attempts to restore pauses video. Problem not just in YouTube. FF; 122.0.1, W11; OS build 22621.3155

In the past two days, any add-on I add to FF browser. does not have a "Pin" option ellipsis activated . Some of my other settings are also botched up: tab used to open on hitting "return" among them.

All comments etc, are either convoluted, unintelligible, and ALL do not address this issue. If someone knows what to do, chime in. many of us have this issue. But please, have a real solution or don't bother us.

I have a website that is now being blocked for 1 week jgonzalez@lungdoctors.com this is my Pulmonary Doctor

and have used this web site for at least 1 year. Being a novice I refreshed my Firefox site and now I have

Pocket which I do not want.

Any ideas would be appreciated very much.

Thank you Judith B. Basch

Hi there,

On Firefox, I'm experiencing "momentum" scrolling where, when I scroll using the trackpad, after I lift my fingers off, it keeps scrolling for a bit.

This is not the same thing as smooth scrolling. Disabling smooth scrolling does not disable this behaviour, and I use smooth scrolling on plenty of programs without it experiencing this "sliding" "momentum" on any of them except Firefox. I've also used Firefox before with trackpads without experiencing this.

How can I disable this?

I have to press the F11 key to see the menus, scroll bars, taskbar, etc but the screen then goes back to full-screen mode.

How do I prevent full-screen ?

In upper right corner of the menu bar, I have what appears is a shield with a helmet (with red banner). This is followed by ever changing symbols, letters, and numbers . When I mouse over it or manually point it disappears. Removal of the pointer brings it back. This shows up on Firefox and Edge browsers. Does anyone know what this is?

A couple of weeks ago, a message came from Firefox saying - do I want the facility of opening a Firefox window on starting it? I thought that would be a confirmation of my existing setting of opening Firefox with the previous tabs. But no. Firefox now opens a separate blank window in addition to the previous window with the tabs.

How can I stop the opening of an additional blank window, which I now have to delete everytime? Thank you

Wishing to view my own html file in my Ubuntu Linux system I pressed the Alt key which I thought would give me a "File" menu. I could not see one. How do I get it?

Could anyone that uses Ublock please visit here to see if the video is being blocked?

I am trying to use an input type of month but it is not rendering or behaving properly when viewed in the latest browser version.

The example from Mozilla tech site is below and when viewed in Firefox it does not work either. <input type="month" id="start" name="start" />

Is this no longer supported by Firefox?
