Is there a problem with firefox for mac?
I installed it on my mac book pro on 2/6/2020 and successfully used it until 2/8/2020. I wanted to use it and when I opened my mac the firefox was totally gone. I reinstalled it this morning, 2/10/2020, and it seems fine so far.
Additional System Details
- User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:72.0) Gecko/20100101 Firefox/72.0
Have you been launching Firefox from the .dmg that you downloaded, or have you been launching it from your Applications folder? You have to drag it into your applications folder to install it. You cannot just click on the file that you download: https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac
Let me know if the problem is something else.
