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 am afraid to update to Firefox 124 for fear of losing the existing order of 100s of open tabs if the default setting of ordering tabs by "Recently Opened" kicks in before I have a chance to change the setting to "Tab Order". Can anyone help me? I'd like to upgrade to 124 if I can do so safely!

I've got an M2 MacAir running the latest version of Sonoma. Within the last week, the battery power has fallen off a cliff. It barely runs for a couple of hours and recharging takes nearly half a day. I'm not running anything unusual just social media & YT videos. This seems to have coincided with the latest Firefox update. I was wondering if this might be contributing to it or if this is a common problem since Sonoma & FF updates?

Anyone any ideas?

Hi Every single one of my passwords is compromised according to you. Therefore I think the data breach is with Firefox . I have set up several unique passwords recently - how are they breached so soon? And why every single one. It is very suspicious. Regards Caroline

Hi there,

About 4 days ago, hotmail suddenly stopped loading on Firefox (though I can still access it on Safari). I've tried clearing my cache and add-ons, etc. I've googled a ton and tried all the things I can find to try, but nothing is working. I am by no means a tech person and so I'm out of ideas and need some help. I know I can use Safari, but I really hate using it and prefer Firefox. Any ideas on what to do? I am using a MacBook Pro - Sonoma 14.4.1

Thank you so much! Jocelyn Pascall

When I download PDFs on my MacBook using Firefox (currently 124.0.2 (64-bit)), they are always blank - I have attached a screen shot.

But if I download the same PDF using Safari, it opens straightaway - 2nd screen shot.

Is there something I need to adjust in Firefox to allow PDFs to open?

Hello. In the last few days when I visit my Shopify website, the pricing on my products is not visible. This is only for me, nobody else has this issue. I do not have this issue on Safari, or on Firefox when I open a private browsing window. It is something to do with Firefox, but I don't want to have to open a private window every time I go to my store. Is there a solution? This has only been happening for the last few days. Thanks

The latest version of firefox for MacOS 14.4.1 has broken the picture in picture function. When enabling PiP, the video window takes up almost the entire screen and doesn't remember the size i set it to, like it did in older versions of Firefox. Another issue is when im in fullscreen mode and enable PiP, the PiP window takes me to another 'desktop', whereas before it would simply overlay on top of my screen.

Hello,

I run a WP elearning site (cd-dojo.com) and I prefer to use Firefox for everything.

Recently I added a plugin and experienced an error and WP went into recovery mode - displaying a message and an exit recovery mode button.

I have since resolved the error, but was perplexed because I could click the exit button but the messaging was persistent. I did everything I could think of - including the recommendations of tech support - until I was ready to reinstall a backup. Then I thought maybe it's a browser issue, so I logged in as admin in Safari and the message is gone. See screenshots below.

Since then I have tried everything I can to remedy with your support information including restarting the computer, clearing the cookies and cache, restarting in troubleshoot mode, and reinstalling firefox. Nothing has resulted in any resolution.

So, I'm presenting this to you. I can continue to work on the site using other browsers but I prefer to use Firefox. Can you help?

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?

Thank you for your assistance in advance. Since I updated my browser, I've encountered some issues when trying to maximize the virtual screen in my tv. I use a Mac and connect the screen to a web TV to watch YouTube in my big tv. However, when I click to maximize the window, the connection becomes unstable, and the virtual screen disappears every time I click the YouTube icon to do this. This problem never occurred before. I would appreciate your help in resolving this issue. Please let me know if you require any additional information from me.

Firefox just stops responding when trying to load a web page. The only way to get it back working is to reboot the computer. I have tried quitting the application but when I try to restart it it doesn't respond and I end up having to force quit and reboot the computer and then it will work fine.

Any idea what's going on?

After years of accessing www.youtube.com with Firefox with no problem, the website is no longer accessible as of yesterday. When I point my browser to that URL, I get a screen with greyed out video previews, greyed out titles, greyed out account access and a search window that does not do anything. I can access YouTube just fine with Safari. I've cleared my cache. Please advise.

In all instances, when I click on a link to view a document on a website, rather than simply pop up to view, the document is downloaded and I am required to save it to my computer. Something in the Firefox settings is preventing the pop-up view from occurring. Not certain where to reset in order to correct this. Please advise

Hello,

I need your help because i can't find solution to problem. On my macbooks air m1 i experience a very annoying thing: Often while i'm scrolling on websites smooth scroll animation get choppy/sluggish for few moments and lagging. It's like animation is FPS dropping during the scroll. I tried lot of things on both device:

- tried without extensions - created new profiles - use without syncing data - disabling hardware acceleration (gets worst) - disable smooth scroll in settings (get worst) - completely remove firefox with AppCleaner and reinstall it - Reinstall macOS and just install firefox alone. I tried latest Ventura and Sonoma

I don't have clue why this happening but ruin user experience very bad. With Safari everything is fine and smooth. On my wife's device (macbook air m3) have same issue.

Do you have any idea how can i fix it?

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

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.

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?
