I run into issues in the Firefox browser occasionally that may be either due to the version of Firefox or the web application that I am interacting with. In order to troubleshoot the issue I often send feedback to the web application creator. Part of the information I send is the version of Firefox I am currently using.
When I go to the about Firefox panel to see what version I am currently running, Firefox does a check to see if I have the latest version. If I do not have the latest version, Firefox updates the browser to the latest version (which I appreciate) but it happens typically too fast for me to see what version I was on when the issue I experienced occurred.
IDEA - TO REMEDY
In the Firefox "about" panel show the previous version number Firefox had installed, prior to updating to the latest version. That way I can report the version that the issue happened on accurately. Note, in some cases I can retry the web application with the new version to see if I still have an issue, then submit the latest version number. BUT, there are times, such as submitting a payment where I am unable to retry with the latest version and the tracked previous version would be of great value.
