Hi, I'm an avid Firefox fan for many years. A noticed that when I have several screens of Firefox tabs open. The characters I type are not the ones that are displayed. If I type them in, for example, notepad, and cut and paste to Firefox it works. The issue also kills an application on my PC and we have to restart it. Is this a known issue?

Please help. Joe

Hi Zonealarm does not have an exemption. I disabled keylogger and will research the suggestion from Senali. I did in fact disable the anti-keylogger on Zonealarm, and am not experiencing the problem. Thanks for your help!

Try with a keylogger extention like nifty keylogger (we can add that add-on) If you have already used a keylogger, turn off the keylogger and reboot the computer.

Hi Senali,

Yes, I am using the ZoneAlarm Extreme Security product with the Keylogger on. I like the idea of my security software looking for keyloggers. Are you suggesting the nifty keylogger is an add on to Firefox? If so I will try it and disable the other.

Before I do that. Is a keylogger known to cause the issue I described above? It is quite annoying.

Please advise and thanks for your help. Joe

Some security software with anti-keylogger features has caused issues in the past where what you type is not what appears in Firefox. They "scramble" and "unscramble" your keyboard input to fake out any keyloggers that may be listening.

In past threads, it was a very consistent problem and didn't suddenly become an issue in the middle of a session or only some tabs. Maybe this is related to single-process (before Firefox 52) versus multi-process Firefox.

Does ZoneAlarm have the option to exempt Firefox (firefox.exe) from that feature for testing?
