This yellow banner is suddenly appearing on my firefox when I am using an online website builder programme and it is stopping it from working and hence stopping me from working. I didn't ask for this error message business, and truly wish I had not updated to this latest version as prior to that update this was not happening. I do seem to remember from some years ago this was a problem too. I have read all the links and articles and I cannot find a way to disable this from happening and it is very frustrating. Please look into this as it is causing me to have to consider using safari again as I certainly won't use chrome as godgle want to know what colour knickers I'm wearing and my inside leg measurement yet all my data goes into someone else's super admin account but godgles won't listen. Very frustrated and I hope that Firefox are not considering going the same way with data collection, advertising and accounts. You stood out as being there for your users and not for advertisers or data gathering or anything so intrusive. I am very sad to think that you are going the same way as them :( please don't we already have google and apple who think they are gods we really need someone who does not want to gather our data or take our info or spy on us.
