Firefox transmits a wrong value for the "safety" codes entered. Serious

In a safe procedure one is asked to enter a special vaule (passw. word, data received over the phone, etc.) , when transmittig the entered value, Firefox makes it wrong, therefore blocking the procedure, for if ones re-tries, the result is still wrong. For ever. VISA uses this procedure during confirming a payment (a secret word is phoned to the person making the request and you must type it down as requested) Also in other procedure (like registering in a working group ) where a similar method is used, the same happens. Opera does it correctly. This is a very serious safety (in the negative sense) problem! Friendship, Giancarlo.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window

I did not try the complex procedure suggested, since I use the process only occasionally and have no control nor knowledge of the receiving item (may be an "edit" box or an "input" command) from the requesting program. The point is that the input typed by teh user (me) is wrongly read by Firefox, wrongly transmitted and therefore refused. A problem of coding? For the rare case I need this service...........I switch to Opera, which works OK, sorry.

Does the form let you see what you are typing or is each character replaced with a dot (like a password field)?

If the form lets you see what you are typing, is the page displaying the correct value before you submit it?

Some forms are designed to show a visible box, but using a script it is written or encoded to a hidden field and the server actually processes the hidden field. That kind of design is a little trickier to debug.

Anyway, I am familiar with a similar form from using a credit card issuer's site and have not noticed any problem on that site. If you want to help Mozilla look into this further, we probably would need to work with a site you are actually having this problem on.

I don't know whether it is applicable to your system, but some ZoneAlarm customers using the anti-keylogger feature reported last year that Firefox received the wrong characters (e.g., When i hit a key to type it cycles through every key on the keyboard). If you are using an anti-keylogger program or add-on, perhaps there is a similar thing happening on your system.
