Can't login to

Hello, I have registered in but everytime I login it displays an error "oops..". I've tried resetting my password too but this doesn't help & cleared all cookies/cache. Any other suggestion(s)?

Thanks in advance.

If you cannot log in to websites after removing the cookies associated with it, clearing your Firefox cache, and trying with your extensions and plugins disabled, you may have a corrupt cookies file in your Firefox profile folder.

You can check if there are entries in the password manager with an empty user name.

Make sure that you haven't saved multiple (uppercase, lowercase) versions of that name and password.

Remove currently saved Password(s) from that domain:

  • Tools > Options > Security: Passwords: "Saved Passwords" > "Show Passwords"

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.


Re: Can't login to

Hello again, I've searched a bit till I found this link: I got exactly the same problem, so I guess I'm gonna need an admin's assistance. This hasn't to do with my browser, any staff member please contact me, since I can't login to AMO forums in order to post.

Thanks for your replies!

Can someone help me please?

Re: Can't login to

Clear the cache and the cookies from sites that cause problems.

"Clear the Cache":

  • Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

  • Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
