Card Payments error using Firefox

[#1]

Quote from: Oldjim

Try starting Firefox in safe mode and see if it is the same

Tried - restarting with Addons disabled which seems to be what was called "safemode"
- no joy - still the same
- This is not hugely important - I can use IE on PlusNet payments ................. trouble is it has triggered our curiosity to find an answer

[#2]

Does your anti-virus monitor websites, in particular ones where you enter payment details?

[#3]

Pretty sure it doesn't -- As I've said before I only ever have this trying to pay PlusNet
- I've used lots of drop downs recently on Xmas shopping online - no other problems at all elsewhere

[#4]

To stop this bug deterring anyone else from making a card payment because of an unusual but not invalid number handling problem,  isn't the real answer to change the way the web page handles the drop down list so that -

• 'January' can be represented by "1" or "01"
  . . .
  


• 'September' can be represented by "9" or "09"

If implemented as above, then in future, this will never happen again !
Trying to debug 'kdhuk's particular setup will only solve the problem once, and this problem will soon happen to someone else.

[#5]

Good idea - could be why I don't seem to have the same problem elsewhere - other sites maybe indeed  don't see it as an error

[#6]

Chris,
Do not know if it is relevant...
Your "I cannot reproduce it" screen shot is showing the EXPIRY date drop-downs
The OP's "Here is my view of the problem" is showing the START date drop-downs

The start and expiry both exhibited the same behaviour for me.

[#8]

What Page Style and Character Encoding (View Menu) are you using kdhuk?

[#9]

Set at Basic Page Style and Western.
...........can't seem to change Western Character encoding - tried Unicode but defaults back to Western when viewing the PlusNet Card details page

[#10]

Another thing it isn't!
I did wonder about GreaseMonkey but as you've tried with all add-ons disabled it can't be that.

[#11]

One other thing to look at,  what's in the actual HTML served  (right click on the start month and select This Frame, View Frame Source) then find the relevant code and what's in the live DOM  (right click on a drop down, Inspect Element,  in the window that appears, expand the 'select' element highlighted)
For me,  the raw HTML look like this  (whatever generates the HTML adds a lot of whitespace to it.. ???)

<select id="startMonth" name="cardStartMonth" class="select">
   <option value="">mm</option>
   
      <option value="01"
      
      >
      01
      </option>
   ...
 

And the DOM matches,  indicating it was served as expected and nothing has modified it.

[#12]

I seem to be missing mm in this line:-
<option value="">mm</option>
see screen shot
Bear with me I'm just about keeping up with the terminology here
In the Frame Source it reads
<select id="startMonth" name="cardStartMonth" class="select">
                              <option value="">mm</option>
                             
                                  <option value="1"
                                 
                                  >
                                  1
                                  </option>

Regarding the screen-shot, you're not missing the mm,  you just need to expand the 'option' to see it.
Ultimately,  the reason Firefox is displaying the wrong thing is that it's receiving the wrong thing,  which would imply something is intercepting and modifying it.
Another thing to check would be the proxy settings in  preferences, advanced, network, settings. usually there's no need for a proxy on a home network,  and some malware changes the setting.
Additionally you can investigate what the browser is seeing using the 'Developer Tools' network option, or if you want to get adventurous, you could install wireshark and use it to see what's happening at the network packet level.

What about Control Panel >Regional and Language options. Is it all set to UK and not customised incorrectly in some way?
Check >Regional Options >Customise >Numbers >Display leading zeros

[#15]

That's under additional settings in Windows 7
