How do i close my browser window - Mozilla Firefox

In all Windows versions:
ALT +F4 key combination will close any window.

Kill it:
Rright click task bar, start task manager, click Applications, select the browser and click "end task"

Try another browser.

Alt+F4 to close window or my favorite Alt+Ctrl+Del will "start task manager" and then click the tab at the top that says "Applications" click the the browser app to close then click "End Task" Repeat until all of the browsers are closed.
Good Luck.......

uninstall mcafee, restart and see if that fixes your problem.

The red x in top right corner should close the window, if not right click e icon on the task bar and choose close window.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/jason_77a19afa8d604dee

In order to close IE, you just need to click on the X that is located at the top right of your browser window.

If this does not completely close IE, you can also check to see all the running applications and processes on your computer by visiting the Windows Task Manager.

You can access the WIndows Task Manager by pressing Ctrl + Shift + ESC.

From what I understand you are now using a new version of Internet explorer or Firefox or chrome browser, all of which use something called tabbed browsing. These browsers open multiple pages in one window as tabs. (Earlier versions of Internet explorer used to open each pages individually, and using the close button will only close that particular window). In tabbed browser each tabs can be closed. If you try to use the close button on the top right hand corner, it will ask whether you want to close all the tabs and close all tabs if answered in affirmative. To close individual tabs click on that particular tab and you will see a small X on the right hand side of that tab. Use it and only one tab will be closed.

Please note that I am using Windows XP so Vista may be slightly different but mostly similar.

Press Ctrl+Alt+Del and open the "Task Manager". Click "Processes" tab and check the box next to "Show processes from all users". Look for the file name of the web browser you are using and here are two common web browsers.

Microsoft Internet Explorer - iexplorer.exe (If you close explorer.exe by mistake, Windows XP users can go to "Applications", "New Task", and type in "C:/WINDOWS/explorer.exe" or Vista users can simply log out and log in through the task manager.)
Mozilla Firefox - firefox.exe

If you use a different web browser, right click the shortcut for your web browser and click "Properties". The file name will be after the last slash ( \ ) in the target box. File names usually end with ".exe".

Click the file name when you find it and click "End Process" but before you do, you are most likely viewing this with a web browser so this window (and all other windows for your web browser) will close as soon you end the proccess. This means make sure you finish what you are doing and be ready for it to close.

try opening "new" pages in Tabs and when you want to exit said page just close the tab.
