Firefox updated itself last night. Went to open browser and Windows 10 came up with a compatibility error. Downloaded 118.01 and things seem to work now. Didn't lose personalizations, history, passwords, etc, but Firefox thinks it's running version 118.0.2. What can I do to remain secure? Thanks.

Firefox 118.0.2 is current, so that would be okay.

An error message about XPCOM missing or about platform version usually happens because of a failed Firefox update that left you with a mixture of old and updated files in the Firefox program folder. This can happen in case security software was keeping a handle of some of the files in the Firefox program folder preventing Firefox from replacing all the files. You need to do a clean reinstall and remove the Firefox program folder to ensure that all files are replaced. You may have to disable security software temporarily in case the problem persists.
