Field entries not recognised

I've been using Firefox on my PC for some years now, but occasionally I have experienced problems associated with filling requested fields. Today's example was a form for arranging a parcel to be collected by DPD. I filled-in the required fields for postcodes for source and destinations. Instead of progressing to the next stage I was asked to enter valid postcodes, apparently not recognising what I'd entered. I did that twice with the same result. I then copied the URL from the top of the screen, and opened it in Microsoft Edge, and I was then able to continue successfully.

That has happened on several occasions over the years, indicating a background fault with Firefox. I'd hate to migrate away from Firefox over such a small problem, but it's something that needs looking into. I apologise if this issue has been notified before, but to date it hasn't been rectified.

Did you try to type in the postcodes manually if you either used a paste or let Firefox auto-fill this data as websites might use JavaScript to monitor what you typed and verify what is entered is valid?

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

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

Thanks cor-el, The postcodes were entered manually, with gaps in the middle. When using MS Edge, I did the same thing.

As the problem has been sidestepped for now, I will have to wait for the issue to appear again before determining if your suggestion works. I'll keep your reply saved until then.
