I had been using the Mozilla Firefox VPN for a few weeks, but now it will not launch. I sign in without a problem but when I click on the VPN icon on the toolbar, nothing happens. I just get the pop-up to try the VPN and "Get Started" (see attachment).

Please advise.

Firefox browser does not open when I click on the short cup. Instead it opens 2 small windows, one is a website I visited previously and the other is Firefox settings. Why is this happening? I have Windows 10 on my computer but that should not have anything to do with the Firefox browser or search engine not opening. When it opened the small screen that only showed Firefox settings I clicked it to open in full screen and now there is no option to make the screen smaller or exit the Mozilla support page. And, now with this full screen I can't even do a screen shot to show you what I am talking about. Does anybody know what is going on with this?

According to everything I CAN see, I have Firefox 150. I am still using Windows 10 and I don't seem to have problems with that. However, I CANNOT get to the Firefox Browser. I am very frustrated with only seeing Mozilla this, Mozilla that, but not Firefox. When I go to the help section I am able to click on Firefox Browser, so I know you still have it. The main item that is very different is clicking on Firefox to open it, and then seeing 3 different ways to login. I'm at a loss, and I'm frustrated. Please help me so that I may sign in to Firefox BROWSER.

By the way, when I click on Themes-Add-ons for Firefox and choose what I think looks like PINK, it isn't pink! It's a very strange purple color. I want PINK. Thank you, RhonCa

I can't do anything with Firefox because I keep getting a message that it is still open, but it is not. How do i close it?

I wanted to refresh Firefox. When I downloaded the installer from the Mozilla website, I got this message: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." I finally downlaoded it from the App store and now I get this message "Your Firefox profile cannot be loaded. It may be missing or inaccessible."

I can't recollect doing anything lately that would have caused such a problem. I don't mess with the registry, and I don't use rogue programs. I do have a Surfshark VPN, which I disabled to download the latest version of Firefox.

I am running Windows 11 on a Dell PC, which is about 6 months old.

I didn't have any problems until reciently.

How can I fix this?

I can't open Firefox. I keep getting the message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.". I can't find it to close. I tried uninstalling it, but I keep circling back to the same message. I tried refreshing it and again same message. I un installled Surfshark VPN, I ran Windows Defender antivirus. I am now out of ideas. I do have two profiles, but the message about deleting them is scary. I don't want to do anything until I understand what I am doing.

Windows 11; all updates are installed, Dell computer purchased in October, with AMD processor.
