I'm trying to set up Firefox on a new Windows 11 laptop and having issues. First, I installed a couple of Add-ons and set them up, I use one to have a Home Page, and another for zoom percentage. And I went into each one and set them up as I want them. But when I closed FF and reopened it, they were gone, as if I didn't install them at all. And all the changes I made to the top part of the browser - icons and overall look - reverted back to what FF is "out of the box." Also, on my old laptop, I went into about:config and changed the ui.textScaleFactor because the default FF top part is too wide for me. But when I went into it on the new laptop, and changed the number, nothing happened. On the old one, when you enter a different number and hit enter, the change is made immediately. Also, I did make FF my default browser on the new laptop, at least I think I did. I clicked the link to do that, and it brought me to a window with a bunch of confusing extensions. I changed them all to Firefox, including E-Mail, and I don't even want FF being the default for E-mail. And I did click the check on top and clicked "Make FF the default browser." But when I open FF, I keep getting asked if I want to make FF my default browser and to pin it to the task bar. But it already is! I should point out, that it's possible I downloaded FF twice, and may have installed it twice. But when I go to Install/uninstall files, just one is listed. And I only have one FF icon on my desktop. So what is going on?
