recently I started getting this pop up every time I leave gmail, even when all I've done is sent a quick note. I did not have this problem before.
Never had this problem in all the years of using gmail and firefox on my macbook pro, but just recently I am getting this message EVERY time I leave gmail. I go back and check, and I have completed everything, but it comes up each time anyway. Even if I just write a quick note to someone and send it, I'll get the message: This page is asking you to confirm that you want to leave - data you have entered may not be saved. What's going on?

Having more than one version of a program may cause issues. You must remove the older programs. Then get the current full installer.
Then reinstall the latest version.
Note: Windows users should download the active_x for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).
Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the active_x.

To get rid of that message, would you try this please :
Type in the address bar about:config and press Enter (promise to be careful, if asked)
Type in the search bar dom.disable
and look for the preference dom.disable_beforeunload
Set its value to true and then close and restart Firefox.
