Unable to login gmail, browser's cookie functionality is turned off. Please turn it on, even after clearing cache, cookies unable, enabling cookies, don't work

Unable to login gmail. After entering user name and password, says, Your browser's cookie functionality is turned off. Please turn it on. Even after clearing cache and cookies, enabling cookies, starting firefox in safemode, resetting firefox, Says the Same thing. I have tried all troubleshooting information provided by mozilla support and all were unsuccessful in solving the problem. I have the same problem with internet explorer and chrome also.

If clearing cookies doesn't work then it is possible that the cookies.sqlite file that stores the cookies is corrupted.

Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookie files like cookies.sqlite-journal in the Firefox Profile Folder in case the file cookies.sqlite got corrupted.


You can remove all stored data from a specific domain via "Forget About This Site" in the right-click context menu of an history entry (Show All History or History sidebar) or via the aboutSmiley Tongueermissions page.

Using "Forget About This Site" will remove everything like bookmarks, cookies, passwords, cache, history, and exceptions from that domain, so be cautious and if you have a password or other data from that domain that you do not want to lose then make a note of those passwords and bookmarks.
You can't recover from that "forget" unless you have a backup of the affected files.

It doesn't have any lasting effect, so if you revisit such a 'forgotten' website then data from that website will be saved once again.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Note that a Reset tries to import cookies, so you may migrate cookie issues to a new profile if you perform a reset.

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

Which security software (firewall, anti-virus) do you have?

Make sure that your security software isn't blocking cookies if the settings in Firefox are OK.

Still looking for insights here. Anyone tried creating a new profile as cor-el suggested? We need to understand the issue if we are going to fix it!

Try a different browser, see what happens. I have a similar issue, and it's only resolved when I use the unofficial 64 bit project for Firefox called Waterfox. I suspect this is something beyond just firefox, and rather related to a resource all browsers are using.

We still have a lot of me-to votes. But I note the original post said:

 I have the same problem with internet explorer and chrome also. 

That would suggest the problem is not Firefox specific maybe

  • due to security software
  • a gmail site problem

Also of course a well used site such as gmail is always going to have some users who will report a problem.

Gmail by the way works ok for me.
