I see the options button, but I have Shockwave flash set to ask, and Netflix never asks to activate Shockwave. Anyway to humor you, I unchecked enable protected mode. I closed, then reopened Firefox, and as I expected, it made no difference in the Netflix error message. <strong>Thanks for trying</strong>. I am running Win 10 32bit, and until FFVersion61 Netflix always worked. I am thinking of uninstalling FF and using Edge exclusively. It seems to have fewer problems. I always liked FF.

The page that you sent me to, is too technical for me to understand. <strong>Isn't there some simple way to save my bookmarks</strong> when I reinstall Firefox? I don't see why I should want to save my profile, whatever that is? What I want is to save my bookmarks to the reinstalled Firefox.
For example, the support information tells me to export my bookmarks as a JSON file that is not one of the options in the export menu. How do I get around that? I never heard of a JSON file type.

<p>Uninstalling Firefox will not erase your Firefox data (bookmarks, etc.).

I assume that this could involve local storage.
In Private Browsing mode local storage is disabled and features like "Resist Fingerprinting" can also modify data as reported to a website, but since a new profile didn't help then this would suggest some external interference.
