If the answers are correct, Tracking Protection should be disabled within Firefox, not on the website. See the What happened to Tracking Protection? article for info.

If that doesn’t help, please provide the address of the website(s) involved.

Do you see the the shield icon at the left end of the location/address bar?

You can check the Web Console for more detail about what content is blocked.

• "3-bar" menu button or Tools -> Web Developer
• https://developer.mozilla.org/en/Tools/Web_Console

You can try to enable third-party cookies temporarily to see if that has effect.

To see all History and Cookie settings, choose:

• Options/Preferences -> Privacy & Security -> Firefox will: "Use custom settings for history"
• https://support.mozilla.org/en-US/kb/Options+window+-+Privacy+panel

http://ocean0fgames.com/ this site says that I have an adblock and I can't see any shield options in this site

If can play the games (which you have not said) then do not worry about what the sites say. Firefox delays tracking cookies by 5secs or so so the pages load faster. This maybe what the pages are seeing. Try reloading the page. Again if can play do not worry about it. Please let us know if this solved your issue or if need further assistance.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

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

Using "Forget About This Site" will remove all data stored in Firefox from this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

You can create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

sorry it doesn't help me

I have refreshed Mozilla as you said

I have refreshed Mozilla as you said

I'm sorry, but I don't see anybody telling you to do a refresh - as a matter of fact : cor-el told you NOT to ......

However, cor-el did tell you to try Safe Mode, as one of your extensions might be the culprit (I'm thinking an add-on like 'Disconnect' for instance) :

I have no adblock

akash.B said

I have no adblock

It could be any other add-on (if you have any) ......

No,I have no an other add-on

I meant any other add on

As you have done everything that was suggested to you, to no avail - would you please take a look at this article

It's an AdBlock article (how ironic), but please make sure that you read all of it - you just might find the answer there (fingers crossed).
