I cannot make Firefox is my default browser

Check in your system if Firefox is seted as default. If in your system Firefox is set as default maybe this message comes up because Firefox is forgetting that it is seted as default

• Setting Firefox as the default browser does not work - What to do
• Default browser

I've already done that few times and I still have the same problem. Even in the options it says my browser is not the deep fault one.

But in your OS system ? Firefox is seted as default?

as I no to yes

Try to redo the default browser setting and temporarily set another browser as the default browser.

i am still getting the same problem as before. I have tried ever think that people have suggested with no look. it is every Time I start up Firefox

You can check for problems with preferences.

Delete possible user.js and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.

You can use this button to go to the currently used Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

I decided to on click the box where it says always make sure Firefox is my browser , and now I don't have that problem any more

I have been having the same problem. I found one solution that said to go to the Mozilla folder in the Program Files folder, right-click the firefox.exe file, click Run as Administrator, then answer yes to setting Firefox as default. It worked, but only as far as running the exe was concerned. I used the right-click method with the desktop icon and the quick launch icon. Now, if i just click the QL icon or double-click the Desktop icon, I still have the problem, but if i right-click either icon and select run as administrator, Firefox launches showing set as default.

I call this a bug. Whether it's Vista's bug or Mozilla's bug I cannot say (though i lean to Vista's bug). I would like to resolve this issue, especially since all web page file icons show Firefox's icon instead of IE's icon, and double-clicking them launches Firefox. It is merely an annoyance having to deal with this every time I run Firefox.

Close Firefox. If your computer has another web browser (example: Win IE) Open it. go to the settings and make that browser the default. If you want, turn off the check if default option. Once you are done, close the browser.

Now open Firefox. Type about:preferences#general<enter> in the address bar. Turn on Always Check Firefox Default Browser. Then press the button to make Firefox the default. Close Firefox. After a short time, restart FF.
