Here is the link where I checked the webcam

Firefox 65.0 is installed on one of the virtual machines with windows server 2016 datacenter edition. There are 22 such machines on a common host, all of them have one problem. Virtual machine parameters - 2 cpu 3.3 GHz 5 GB RAM 50 GB HDD Installed ManyCam for virtual webcams. As you can see on the video, a drop occurs immediately after I give permission to use the webcam. I tried different versions of Firefox 65, 64, 63, 62, 61, 60 all have this problem. At the same time, the camera is available and working correctly in another browser.

Did you upgrade, or use the full installer?

Let’s do a full clean re-install;

Download Firefox For All languages And Systems {web link}

Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Note: Check Both Folders

Mac: Open the "Applications" folder.

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux;

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove any profile folders.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again. This shows how to Start all Computers in Safe Mode; Free Online Encyclopedia

Any news?

Hi Qwaros, I recently fixed a bug that may have been causing the crash you are seeing. I was wondering if you could retest with a Nightly build of Firefox let me know if it is still crashing for you. Thank you for the crash reports!
