I am unable to get some websites, including Mozilla, to recognize the fact I am running the most current version of Firefox. I have automatic update on my system, so new releases are downloaded automatically. Currently I am using ver 53.0 32 bit. Since I am using a 64 bit system, is that a part of the problem?

For some reason, the version I am running is not properly showing up where ever it is websites look to determine the version I am using.
