Firefox Support Forum

Whenever I use the picture in picture feature, it always opens up in a bigger tab instead of the floating PiP. I am unable to adjust the sizing whatsoever. Is there a way to get around that?

I can't find a way to disable tabs scrolling. This is highly confusing, I have to always look for my tabs and do extra clicks and scrolling. This is very distracting. Also those two buttons - "<" & ">" - they occupy extra space. The left one is especially annoying because I expect a "+ new tab" button to be there. I don' want to test/use this new experimental feature, how can I turn this off? Thank you.

I use a MacBook AIr with OS 14.4.1 (Sonoma) and want to add a short cut link to Proton Mail (Free version) that I can put in my MacOS Dock. I am using Firefox 125.03 version.

I used to have a link in my Mac Dock but then I tried the trial of their desktop app-- and when that ended recently, I did not know how to set the Dock link up again. I tried directions for other browsers but they did not help.

'The link I want the short cut to go to is' https://account.proton.me/mail so I can sign right in to check my email.

So I checked Proton's support site for help but it has directions to do this ONLY from Safari and another browser, NOT Firefox.

If you can give me some straightforward directions to add the shortcut to Proton Mail sign in back to my Mac Dock, I would be grateful!

I really enjoy and feel safer using Firefox, by the way! thank you

I am using theme called WhiteSur to imitate Safari, as that is the browser layout I prefer. However, this doesn't change the position of the close tab button and leaves it on the right hand side. I found a way to change it, using the code .tabbrowser-tab .tab-close-button {

 margin-left: -5px !important;
 margin-right: 2.5px !important;

} Unfortunately, this doesn't change based on the size of the tab, so if I set it to a size that is good for only having 1 tab, it will look bad or be off the screen for the other amounts of tabs. Is there a way to detect the width of the tab or the amount of tabs open and dynamically set the margins based off of this? So I could set it as (width-of-tab)-x and that would always keep the close tab button in the same spot, regardless of tab size. Thanks!

Hi, I've been trying to get the Multi-Account Containers Add On to work on my computer for quite some time. Would be very handy for me. When I add the Add On to my browser the icon on the top right of the screen just won't show up. Don't know what I've been doing wrong...? How can I access the container settings someway else? I've made changes to my FF settings in regards to privacy via the recommendation from Sun Knudsen but don't really see an issue here. Thanks in advance!

macOS 10.15.7, Firefox 125.0.3

The attached photo shows the startup page that appeared today, yesterday that page had 12 of my most frequent websites loaded in place of the ones you see now. This page keeps changing on me and it's infuriating to have to remake it every few months.

What is going on??

I have recently refreshed Firefox on my laptop running MacOS. Previously I had changed the full-screen-transition in about:config to be zero, but since refreshing changing the setting hasn't disabled the transition. My config is this currently: full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 full-screen-api.transition.timeout 0 Despite everything being like before the transition persists... I'm currently on the latest version of Firefox (125.0.3)

So on my macbook when I enable fullscreen the anmation is super weird. first it stretches the video to the top and then just expands to the whole screen, when I go out of fullscreen is stretches to the bottom and then goes out off fullscreen. for example on safari it just expands the video until it takes up the whole screen. I have gone in about:config and disabled the fullscreen animation but that did nothing.

At one time, I was able to swipe left on my trackpad and go back to the previous page on firefox. I can't seem to find where to set that preference. I'm running MacOS.

Ever since the latest update, the picture-in-picture function stopped working properly. If I activate it, the video will automatically go to full screen, and I need to press the full screen button multiple times to move it down to a small box. I am using Firefox on a Mac laptop.

I'm running a UI deployment with a web-app and Firefox on an Ubuntu system.

I'm running Firefox with the flag "--kiosk" to place it into kiosk mode (booted from the command line upon system boot). This works fine, and boots up Firefox to the page I want (my web-app) in kiosk mode (full-screen, etc.)

However, I get very annoying popups that are not acceptable for deployments in front of customers. I have tried, but CANNOT suppress all of them, or, when I thought I did, they came back a month later.

Popups:

1. "Keep pesky trackers off your tail. Open my links with Firefox" 2. "Welcome back" 3. Others like this...

These are Firefox browser popups, not related to popups that other websites can put up, and block the entire screen with an overlay until they are dismissed. My deployments are only going to a single web-page that I control (which has no popups) and there is no keyboard on the deployed system, so people cannot navigate elsewhere.

Things I've tried:

1. Firefox is installed via snap, which provides "snapshotting" configuration for the Firefox snap. I loaded Firefox, cleared the annoying dialogs, and then took a snapshot (theorying that I set Firefox configuration when doing this, and I capture that in the snapshot) and re-installed it onto a new system. Still go popups 2. Looked into user.js preferences. I can install this file onto the system, so I looked through https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs and this is how I initially got all the popups to disable themselves. I looked through that list and tested most of the recommended settings until the popups disappeared. However, after a month or so, I'm beginning to see the popups again.

Any suggestions from Mozilla or others that run into this issue?

Hi there,

I need to be able to use Command-I (for italics) or Command-B (for bold) when using Firefox to write emails and enter information on other websites WITHOUT Firefox opening Page Information or Bookmarks.

This is basic browser functionality! People use browsers to write emails and other online documents, and the hotkey combo for things like Bold and Italics on Macs are Cmd-B and Cmd-I. All such websites I use recognize that as a standard, but Firefox insists on using those same commands for browser features I almost never use and certainly don't need hotkeys for.

All the information I'm finding online on how to fix this is deeply unhelpful and far more complicated than I can handle. Can you please tell me if there is a simple way to stop Firefox from pulling up Page Information and Bookmarks as a result of keyboard commands, or at least for me to change what those commands are so that they don't conflict with industry standard commands for text formatting on the vast majority of websites?

I've tried going into Full Screen mode three different ways:

• Clicking the green MacOS button in the upper left of the window
• In the Firefox menu in the upper right, to the right of the Zoom choice I click the full screen icon
• Pressing Command+Shift+F

But whatever way I do it, I still see the tab bar, address bar, and bookmarks toolbar rather than a true full screen. Not sure what I'm doing wrong.

Over the last week, a little purple icon appears in upper left corner of my firefox browser, it looks like a person viewing a screen. It sits right on top of the red-yellow-green circles that allow me to minimize, enlarge, or close the browser, and renders Firefox unusable. How do I get rid of it?

While using firefox with mac trackpad or magic mouse it's really easy to accidentally middle click to a tab and close it. It's really frustrating to loose a tab. I guess it wouldn't be so hard to put an option to disable that function. That would make life so much easier. And there are LOTS of requests for the same thing in this site many of them more than years old.

Hi. I can't access my add-ons that I installed. When I click on the extensions icon it doesn't open that little menu like it does for other people, but it takes me to 'about:addons' in a new tab. I also want to pin my addons to my toolbar which is also not working. Please help me out

When using Chrome Dev Tools, I can block a request, and when I open or close Dev Tools, the request is still in the "Network request blocking" tab. It means it keeps a history of networks which I blocked.

With Firefox, as soon as I close my Dev Tools, my blocked requests are gone. Every time I open my Dev Tools in Firefox, I need to search through my notes to remember which requests I need to block, instead of being able to simply select a request from a list of previously blocked requests like in Chrome.

I am setting up a new mac computer (Mac book Air M3 with Sonoma 14.3). I have installed Video Download Helper. The icon appears in the Applications folder and the Dock, but not in the Firefox toolbar. How can I get the icon back? Many thanks.

When I try to log into my AMEX account with FF, nothing happens. The screen refreshes itself, but no log in, and no error or other kind of message. I have entered my User Name and Password manually and using Auto fill, no success.

This problem was posted in January 2020 and I have tried all of the solutions. I have cleared cookies and cache for ALL sites and cleared saved logins for Amex. Still does not work. I have tried logged in and incognito mode. Still doesn't work. I can log in on Chrome with no problems.

It was working fine a few days ago.

Thank you so much for help!
