Barclays Bank
If I try and log onto my Barclays Bank account through Firefox I have started getting a message that your Browser has sent an unrecognised command. I then log on using Google Chrome and it goes into my account without problem. How can I log on as I used to via Firefox?

Are you still able to log in?

If there is still a problem, Start Firefox in Safe Mode {web link}
by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh).
Did this help?
While you are in safe mode;
Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Dear Fred
I have logged on in Safe Mode but still have a problem. I can log onto Barclays Bank site but if I try and do something on the site I get a message that says "Your Browser sent a query this server could not understand" This has happened over the past month after many years of being OK. By logging on using Google Chrome there are no problems. Graham Richings

If clearing cookies didn't help then it is possible that the cookies.sqlite file in the Firefox profile folder that stores the cookies got corrupted.
- rename/remove cookies.sqlite (cookies.sqlite.old) and when present delete cookies.sqlite-shm and cookies.sqlite-wal in the Firefox profile folder with Firefox closed in case cookies.sqlite got corrupted.
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
