First of all, I am not qualified to use Linux, although I have been running it for several years with mixed success. I recently installed Firefox version 62.0, which is not great, although it is much better than Debian's Firefox ESR. I used some special method which turned up on a DuckDuckGo search. As a preliminary step, it had me install something called Snap. The whole installation process was simple, virtually automatic. However, since Sept 21, I have been receiving notices that Firefox is unable to download version 62.0.2. I have also been unable to download v. 62.0.2 manually. I used the "locate" command which indicates that several Firefox files are in directories such as "/var/lib/snapd/desktop/applications/firefox_firefox.desktop," among others. I suppose that Firefox is looking for a certain file in a directory, which is in one of these snap or snapd directories. I am reluctant to attempt to uninstall ver.62.0, and then attempt to install ver.62.0.2. I believe I could download and install the ver.62.0.2 tarball, if I knew what directory to download it to. Can you tell me what the name of that directory? If so, I might be able to find that directory in the snap or snapd directories that I have. Thank you for your courtesy and patience in assisting with this matter.
