Firefox Support Forum

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.

When choosing biometrics for 2-factor authentication, sometimes Firefox will only prompt for a physical hardware key, and Touch ID does not work. Support for built-in biometrics is inconsistent.

For reference, I am using Mac OS Sonoma 14.4.1 with an ARM processor.

For about 6 months now, I've been having a strange problem with Firefox leaving behind ghost entries on the Win 11 taskbar.

I have a laptop attached to a dock which is connected to multiple monitors. If I have a FF window open on one of those external monitors and disconnect from the dock, all the tabs that were open in that FF window will become ghost entries on the taskbar. (see attached image).

It doesn't matter if I close FF entirely, these entries remain until I restart the computer. If I click on one of them, it opens up a brand new, blank FF window.

Has anyone else experienced this or have any idea what might be going on? I tried doing some investigating a few weeks back and I remember finding something in the task manager about COM Surrogate that seemed connected, but I didn't get beyond that.

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.

I had to delete and add back several accounts due to a change in servers (cox.net to yahoo.com). Prior to this I just had the All Folders, Local Folders and below. Now I have the Unified Folders and below, which are essentially a duplicate of the folders in the old All Folders. (See attached image) Not only is it making things confusing but I'm storing duplicate emails and it seems to be affecting performance, Thunderbird now randomly quits and restarts. So, how do I delete either the All Folders or the Unified Folders and move the few sub folders that are unduplicated into the remaining group?

I’m using the official ShadowsocksX app to relay network connections through a Shadowsocks server, and Firefox seems to be having compatibility issues. The browser does not load pages when proxy settings are set to “auto-detect” or “use system:” I’m getting the “Unable to connect” error message. Manually setting the SOCKS host to 127.0.0.1:XXXXX does fix the problem, but that also means I have to switch back to “system” whenever I turn Shadowsocks off.

Neither Safari nor Chrome requires manual action to relay connections on the same computer.

On a different computer, I’m using the Outline client to connect to the same Shadowsocks instance. Firefox does not have issues with that.
