my firefox was moved to the trash and the trash has been emptied is there anyway i can get it back and its history?
my partner removed the firefox app from our mac and i believe he did this so i couldnt retrieve any history from it! please tell me if there is a way to get it back with its history
Simply deleting the program doesn't necessarily remove your history. I think that would need to be done as a separate step.
History is stored in a "profile" folder. This article describes how you might be able to locate it: Profiles - Where Firefox stores your bookmarks, passwords and other user data. You would need to reinstall Firefox in order to actually view the data conveniently.
On a Mac you may also have the Time Machine to restore previous version of files (places.sqlite) to restore history unless Private Browsing has been used.
