Since loading FireFox 4, I have lost the "Close tab" facility, so only have the option to exit - Is this correct?

If I follow a link from an e-mail, I can no longer just close that tab to return to my e-mails, only exit, where I have to login again. Surely this is wrong!

Where are you looking for close Tab?

You can middle click a tab to close the tab or right click a tab. If you want to do that via the File menu then you need to use the keyboard (Alt+F) to open the File menu because some menu entries are hidden in Firefox 4 if you use the mouse.


Set the pref browser.tabs.closeWindowWithLastTab to false on the about:config page to prevent closing the last tab from closing that window.

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
