I have noticed several issues in the database across several projects that are related to the browsers "Back" button. That is because data and state information is not saved prior to actual user execution. Any user inputed data, queries, attachment selections, etc will all be destroyed if the back button is pressed. This is extremely frustrating for me because I have a mouse with fwd. and back buttons near my thumb, and I frequently press them accidentally. I am new to Jira, but have alrady had about 3 incidents that have caused me to loose detailed bug reports. This costs the company money, and wasted time every incident. It just seems prudent to prevent this from occuring by either saving the data in a temprorary location, or by warning the user if data has been submitted, and the back button is pressed. There has got to be a way to either prevent this, or reduce the risk by warning users before it happens. This issue is too frequently submitted in Jira, and Confluence to ignore.
