During validations errors occur. For example, I paste ID "sam" and PW "john" into form's fields. Firefox 3.0 pastes ID "sam " and PW "john " - WITH added spaces!!!! Of course, form validation does not work. It is not happening in Firefox 2.x! Tested many times. I store my web passwords in Excel file and now it is a pain in the neck to delete last character each time I copy/paste them into web forms. Reproducible: Always Steps to Reproduce: 1. Enter data "sam" in Excel 2003 file. 2. Copy data "sam" from Excel file and paste into any web form in Firefox 3.x 3. The pasted data is now "sam " with added space!!! Actual Results: The data copied/pasted from Excel is a value with added space!!! Expected Results: The data copied/pasted from Excel has to be an exact value as it is in Excel!!!
