  Almost everytime I close Firefox I go back to my homepage first.
  Almost whenever I boot Firefox I get the message on the screen ' well, this is embarrassing, Firefox can not recover your windows and tabs "and I have to select Restore Session.

  Try using ' Firefox/file > exit ' (Mac: ' Firefox > leave ";) Linux: "file > exit ') to close Firefox if you're doing that by clicking on the X close in the title bar.

• Firefox does not open on Windows 10 no matter what I try. Is there something that can solve this problem?

  I tried to contact support Windows 10 and they were useless. It was working fine all day and does not open all of a sudden.

  This sounds like a file in your Firefox profile may be damaged or not valid. To check if this is the case, you will need to create a secondary Firefox profile and test to see if you can open Firefox with this profile.

  This can be done using the Manager of profiles for Firefox which can be downloaded from Mozilla's FTP server. There is no installation required, the program is contained in a ZIP file. Simply extract the ZIP file and run the executable file inside.

  How to create a second profile Firefox, please see this support article:

  • Use the Profile Manager to create and delete profiles Firefox

  Note: Do not delete the old profile because if it is damaged, you may be able to recover your bookmarks and settings. For more information on how to proceed, please read the article of the recovery of data from an old profile .

• Firefox does not close when Windows stops

  When Windows (in my case: Win XP SP3) stops, it sends a message ("QUERY_UNLOAD" in many programming languages) that active programs can finish their job (e.g. lay on unsaved data), then exit. It seems you developers have reached Firefox v25 and not thought of programming this little piece-> Windows stop - a Firefox open don't give a fuck on the output, you must cancel it via Windows.

  It would be nice to have this little programming effort done - finally - thank you.

  Firefox may have need of more time to close properly that allows Windows and in the case where Windows is abandonment of Firefox closing process then you given are damaged, then always first close all programs in particular Firefox before close the computer or check if you can make Windows do wait at least 30 seconds or more (you can check in the Task Manager to see how much time Firefox takes to close).

• Firefox does not paint the window if Windows 7 Basic theme is enabled and Replicator port USB Fujitsu PR07 is used

  If I use the "Windows 7 Basic" theme on my laptop (Fujitsu Lifebook A532), the Firefox window is not painted.
  I see only the edge of the window, the content is not. As soon as I switch back to the theme of "Windows 7."
  It works again.
  It could be related to the graphics (from Intel) driver of my new laptop.
  Before I had a desktop computer and not had this problem.

  Update: the problem only happens if I use my port replicator (Fujitsu USB Port Replicator PR07).
  If I unplug the Replicator and only use my laptop, any computer screen is fine.

  Install the latest drivers solved the problem

• Firefox does not start in Windows 8 and none of your suggested solutions worked

  I was not able to start Firefox and I get no message at startup. I tried all the solutions of your support pages, but none works, as for most of them you need to open the browser.
  I uninstalled and reinstalled the browser, but in vain.

  It is possible that your security (firewall, antivirus) software blocks or limit Firefox or the process of plugin-container without you inform, possibly after the detection of changes (update) for the Firefox program.

  Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

Double-click it and change its value to false.

  Another way to download files without tweaking the above-mentioned preference would be to click right on the link that leads to an mp3 file or right click on the drive in firefox and choose to download the file like that...

  Mozilla Web page keyboard shortcuts.

  Reading the title of this thread, so a different answer.

  Firefox does not use the Windows key for all of the keyboard shortcuts in Firefox. Mac and Linux do not have a key "Windows". This article is for Firefox strictly keyboard shortcuts.
