I went to sign in to a website today and could not - nothing pertinent would load. I disabled ad blocking and tracking blocking extentions one by one in an attempt to figure out which of them might be the problem. When that didn't work, I disabled all of them together - still the page would not load. I then went to MS Edge, and the page loaded fine - I have only one ad-blocker extension on MS Edge. That left me to believe that the issue may have been that I am blocking ALL 3rd party cookies in FF. I decided that WAS the problem after returning to FF and removing the checkmarks from Tracking Content, Cryptominers and Fingerprinters. I called the website to talk to technical support. I wanted to find out what 3rd parties were involved so I could decide if I wanted to turn off the blocking of those cookies while using that website. I was told the company and it's website are not affiliated with any 3rd parties, and so their website does not attempt to set any 3rd party cookies, the user does not need to allow/accept 3rd party cookies while on their site, and therefore, my blocking of 3rd party cookies would have no affect on whether or not I can access their website. INSTEAD... I was told that the 3rd party cookies are in my browser, a part of my browser, so that my browser, and in this case, specifically Mozilla, can keep track of my movements/activities and taylor advertising and other such crap to me. Now...I did not think my browser actually cared where online I go unless it's one of those websites that FF will block my progress to, advise of an issue and ask if I really wanna keep on going. I thought a browser was simply the vehicle, like a car, that gets you to the store, and it's the store that has the salepeople trying to get you to buy stuff. If Mozilla is setting [tracking and 3rd party] cookies for Mozilla's benefit, why would users be given the tools to block cookies and trackers and other such invasions? Or are these tools just there to make the user feel like they have control, and in reality those tools/settings mean absolutely nothing? Am I wrong? Or did the individual I spoke with just not know what the bloody hell they were talking about?? 'Cause if they are right...then I'm '''VERY''' disappointed in Mozilla and FF. I've been using FF for MANY years because I had more control than what users of Microsoft browsers (and a few others) have. WHO is setting the cookies? _____________________________________________ Win10 Home, Vs 21H2 (OS Build 19044, 1645) Mozilla Firefox, 100.0 (64-bit)
