Repeatedly getting "Bad Request" when trying to log into paypal...


Since the last FF update occasionally when I go to log into my Paypal account instead of reaching the log in page I get a "Bad Request" message.

If I clear my cache and cookies and then go back to the log in page everything works. But then any current sessions I was in (gmail, forums etc.) are logged out and I have to re-log in to them, very annoying.

Please tell me this problem is being addressed? When I get this "Bad Request" message I can go to safari or opera and everything is working fine, so I am fairly sure the problem here is in Firefox, not with Paypal.

This issue can be caused by corrupted cookies.

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

  • "Clear the Cache": Firefox > Preferences > Advanced > Network > Offline Storage (Cache): "Clear Now"
  • "Remove the Cookies" from sites causing problems: Firefox > Preferences > Privacy > Cookies: "Show Cookies"

Yesss.s... as you might have noted in my original question:

"If I clear my cache and cookies and then go back to the log in page everything works."

The problem is... that's only a temporary solution, the problem keeps coming back.

However I have not tried the offline storage cache clear, will try now hopefully that permanently fixes the issue.

The offline cache is only used for special applications (you need to give permission), so that probably doesn't have any effect.

If your cookies get corrupted that often then you need to check other (security or cleanup) software and make sure that they do not mess with files in the Firefox Profile Folder.

Thanks, I don't have any security or clean up programs running unless 1Password counts, but it's only a password manager not a security program per se. The last time I ran a clean up program was months ago, long before this problem started.

FYI Running OSX 10.6.7 on a 2006 iMac.

Make sure that you have the latest SQLite update installed.

Question owner

I'm sorry but I don't know what that is or how to install it.

Do I really need to manually install files to get Firefox to work properly?

I have this problem too on ubuntu linux laptop with firefox. It is a pain. I can't keep closing firefox and clearing my cache when I'm developing. Am about to switch to google chrome that doesn't get this error.
