Hello,

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

1. Click the menu button and click History button, and then Clear Recent History... .
2. Under "Time range to clear", select "Everything".
3. Now, click the arrow next to Details to toggle the Details list active.
4. From the details list, check Cache and Cookies and uncheck everything else.
5. Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.

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

Thank you.

This does not fix my problem.

What's going on: there's a difference in behavior between Firefox in Windows and Firefox in Linux. If you check the warning option for redirection (advanced settings), Paypal works in Windows but not in Linux. Uncheck it and Firefox works in both.

This is a bug in Firefox. Paypal won't do anything about it because Paypal works correctly in Windows and they don't give a damn about Linux.

I'm posting this on all the related threads.
