1) First, how do I change preferences? Easy on my Mac desktop but how on my iPad? 2) I use Dogpile. I saw a notice that their website is for sale. Is that causing a problem in Firefox when going to one of the websites listed when I do a Dogpile search? 3) I went to a Reddit site using Dogpile. After viewing the Reddit suggestions etc, I tried to close out of it using the square box in upper right corner of Firefox. That has never before given a problem. This time when I clicked on it the tabs showed up as usual and with the x for closing them. Clicking on them did not close any of the tabs and did not show a flash, as if the tabs were nothing other than images. When I closed and reopened Firefox, Reddit was still the tab. I could not go to another website. This problem would not go away. I even closed and re-opened the Apple IOS and Reddit was still taking over Firefox. 4) How can I eliminate the requirement to enter passwords and all the security rigamarole when going to gmail, facebook and other sites? 5) Even now there are the number of tabs still showing in the square at the top right. There is a purple circle with the white eyes in it superimposed on the upper right corner of the box. I know that after I send these questions and go back to Firefox, Reddit will once more be in control. 6) Is there a better Firefox for Mac IOS than the one I now am using? Chrome is working better but I'd rather use Firefox.
