Hi, When I visit [https://messages.google.com/web/authentication https://messages.google.com/web/authentication] with Firefox's history setting set to "never remember history", a blank white screen loads. The following custom settings allow for the site to function as expected: Always use private browsing mode '''unchecked''' Remember browsing and download history '''unchecked''' Remember search and form history '''unchecked''' Clear history when Firefox closes '''checked''' with all of the settings for this option as '''checked''' However, when the following Firefox history setting is changed the site becomes nonfunctional: Always use private browsing mode '''checked''' I am a security conscious user who would prefer to have Firefox never remember my history at all times. I want to be able to use the Firefox Desktop browser to utilize Messages by Google's web client. I followed all of the instructions from a similar post on the Firefox forums, [https://support.mozilla.org/gl/questions/1257862 https://support.mozilla.org/gl/questions/1257862] , and I isolated the history setting as the source of error to my problem. It would be helpful to all parties (Firefox users, Google Messages, and Mozilla Firefox) if we determine that this is a Google Messages' web client issue or a Firefox Browser issue.
