Look for the Profile Folder field under the Application Basics header, and click Open Folder.

To do this, click Help > Troubleshooting Information from the Firefox menu bar. You'll need to navigate to the folder where your current Firefox profile is stored. This will almost always be sufficient, but just in case this folder isn't created, you can go ahead and create a secondary backup by following the steps below. If, after restoring your old data after a Refresh, you still notice the same problems occurring, simply try another Refresh without copying the data, or by copying it pieces at a time, so as to isolate the true cause of the issues.ДЄ Firefox Refresh creates a brand new user profile with only the most essential data, and by default, moves your old user profile (and with it, all of your data) to a folder called Old Firefox Data on your Desktop. That said, a Refresh once all of your data is backed up can't hurt, and can be the quickest method for eliminating problems. Therefore, if you can afford the inconvenience, building Firefox from scratch all over again is a more superior, leaner option to importing old data. This means that Refreshing Firefox and immediately restoring everything from your old, affected user profile may leave you with a refreshed profile that suffers from the same issues. Firstly, note that there's good reason a Firefox Refresh removes your extensions and preferences - these are usually the most likely cause of problems like slowness and bugs encountered in Firefox.
