Firefox Support Forum

I welcomed the Picture-in-Picture feature to the Mac, which allowed me to watch YouTube videos while performing other tasks.

Recently when I have clicked on the Picture-in-Picture icon, the view does the exact opposite of what I want to occur. I want a small window that I can move around and resize. Instead, the video goes Full Screen.

I've tried right-clicking on the icon and on the video, double-right-clicking, looking through Firefox settings, updating to the latest version, etc. -- but stiill don't know how to recover the Picture-in-Picture feature. How do I get that back? Thank you.

Hi,

I'm new to Firefox. I have a Facebook account which I have no issues with when using in Opera. But when I try to sign in to FB on Firefox it doesn't recognise my password. So I changed it yet it still isn't recognised. Any suggestions would be appreciated. Thanks, martin.

Hi!

I have two Firefox windows open. One is of my 'Personal' profile and the other is of my 'Work' profile. (Both set in 'about:profiles'). I would like to switch between the two using hotkeys.

While I'm able to switch between Firefox windows of the same profile using the default "Cmd + ` ", it's not working between windows of different profiles. "Alt + tab" works of course but that's slow if I haven't activated one of my profiles (window) for a while.

If there isn't a native solution, I'd also be interested in hearing about Lua + "Karabiner-elements" workarounds if you are familiar with them.

Thanks!

I am using Firefox 85.0.2 (64-bit) on a Macbook running OS X 10.13.6.

This problem has been afflicting me for six months or so. On certain websites that open a new page in a new window, the new window instantly enters what I would describe as a "resizing loop": the window starts small and immediately maximizes. Each time it fills the screen, though, it immediately shrinks back down and starts again. This looping behavior continues endlessly, until I kill Firefox or somehow manage to get the malfunctioning window to close. On my employer's webmail, for instance, I'm not able to compose a new message, because it tries to open a new window and gets stuck.

The resizing is very fast and very incessant, fast enough to induce nausea in the unsuspecting user. Can anyone offer any suggestions?

Firefox homepage has suddenly started appearing as narrow vertical page. When going to fullscreen, menu bar disappears but reappears when cursor is on the next toolbar down. When it reappears there is no yellow minimize button. Also, can load gmail through Safari but not through firefox

I'm really annoyed by Telegram and Email tabs flashing at me constantly. I need this to stop. I've tried the solutions at https://support.mozilla.org/en-US/questions/1185683 and https://support.mozilla.org/en-US/questions/1107234, but I think they're out of date.

I'm getting this error message on a site I have visited for 10 years without a problem. Last week this error message came up. Its for a financial website. I have been able to reach the same website through Safari and Opera so its a Firefox issue.

Basically the only one showing up is uBlock origin, others show up as enabled when I go to the Manage your add-ons page, but not in the toolbar. I've tried resetting everything to default settings, updated every add-on, enabled history collection.. nothing has made a difference. Any tips would be very appreciated!

Hello !

This week, I reset my computer. I had been logged into my Firefox account since February 2020 and noticed that my bookmarks and other stuff would be saved.

When I logged into my Firefox account in the web browser, nothing happened. I lost all my bookmarks.

It's very wiered because i really didn't get anything back, and i did'nt make a backup of my bookmarks before my reinstallation.

Someone has a solution to help me get back my bookmarks ?

Recently I have issues in Zoom meetings. To make browsing a bit more private I went and activated some of the settings from privacytools.io, but I can't remember changing privacy settings before the problems started occuring. On the Firefox Beta channel I don't see any video streams (not even my own) and on the nightly channel I hear others audio speed up and they sound like mice and they here me extemely slow.

Does anyone else have these issues or an idea which settings might cause this?

So, I'm browsing shop portal of the website (https://fablabfactory.com/en/product/carbide-3d-bits/) with FF, but the Add to Cart button is misplaced, but perfect in other browsers.

Is this a programming issue, or a FF issue, please? Screenshots below.

Hello,

I'm using Firefox 85.0.2 on macOS 11.2.1 and I can't load the PKCS11 Device Driver for my eSign. All the necessary drivers are installed on the system and the Charismatics Scard Utility recognises the devices properly. What's even stranger, is that I was able to add the device in Thunderbird (78.7.1).

Can anyone help me figure out what's wrong and get the device working, please?

Thanks!

The download links from Apple are still not working over several versions of Firefox. The links should open the App Store but for some reason they don't using Firefox. They work from Safari of course, but they also work with chromium-based browsers.

I wanted to ask whether I can still use Enhanced Tracking Protection while still using Facebook Container and Multi-Account Containers. It looks like the option is not showing up in the preferences. Does use of ETF undermine using the other two? Which one is better to use? I don't want to lose the function of Facebook Container to block Facebook trackers from all the websites, but I also want other websites to be kept in separate containers as well.

Hello,

Is there a resolve for missing or broken images in YahooMail while using Firefox? I think I've exhausted my research into the matter. It works in Safari with default settings.

Thanks in advance for your help! J

We have a site that for some reason just started getting blocked by FireFox's Tracking content setting in private browsing mode. We have a Production build that still works but our QA build does not. For the life of my I can't figure out what changed that would have triggered Tracking content to start blocking the site. Basically the site will load but we only get a blank page.

Is there any way to debug what exactly the Tracking content filter is blocking?

Is there some way to pass POST data when navigating between containers? As someone who uses searX as their search engine, which uses POST requests to perform searches, it is very inconvenient that I cannot make searches when the site that I'm searching from is in one container and the search engine I'm using is set to open in a different container, as the data containing my search request does not actually get passed.
