    Hello CmmTch - I have Dell xps-13 Win10 laptop that I just checked and default browser on it is still Firefox. Here's the thing. It is still on version 1803 of Windows. I know one can uninstall updates but I'm a little afraid to roll back my desktop Windows to 1803. There are at least 6 1809 updates on it. Maybe I can roll back to the time I still could choose default browser which would be April. Do you have any advice? Have you ever uninstalled Windows updates?

    Sorry but I don't have any experience uninstalling updates, I don't think it would be a problem, it is something to try but consider this, your system should be kept up to date. I'm confused about what version of W10 you're running, you say and show 1803, the KB is for 1809 so you wouldn't have gotten it with 1803. You also won't have 6 other updates for 1809 on a system running 1803.

    I would try reinstalling/updating Firefox, see this page, Firefox Help Firefox Help has a wealth of information. Right in the middle there's an 'Install and update' button for the Firefox browser.

    Then near the bottom of the buttons is one labeled 'Get community support' that is a forum that has some very knowledgeable posters that really know the Firefox Mozilla product.

    Sorry CmmTch. I haven't been clear. I have a new Dell 8930 desktop computer, installed last March. That is the computer I am having trouble with and the one that is completely up-to-date with Windows 10 v1809. I also have a Dell XPS-13 laptop computer that I use mostly for travel. It is the one updated only to v1803.

    The trouble with your recommendation that I reinstall Firefox is that when I go to Settings>apps>default apps>web browser ONLY MS Edge is on the list, also "Look for the app in Microsoft Store". In other words, the default web browser choices do not include IE11 for instance, nor Google Chrome, also on my computer. MS Edge is totally locked in, no more choices for me. I don't think reinstalling Firefox would gain me anything.

    Go to this page Download Firefox — Free Web Browser
    — Mozilla
    Click on the Download Now button to install Firefox.

    Here is a link describing how to download and install Firefox if you want to look at it before going to the other link, How to download and install Firefox on Windows | Firefox Help

    Once Firefox is installed, it may give an option during the install process to make it the default browser, that would address the issue. Also there's an option in Firefox under Tools > Options > General to Always check if Firefox is the default browser if you can ever open a Firefox browser.

    Problem solved. DO NOT DEFRAG an SSD

    ATTENTION: I woke up in the middle of the night last night and was mulling over my default browser problem when it occurred to me that on Friday night I ran Auslogics defrag program's "optimize SSD". That could be the problem.

    This morning I did a system restore back to May 1st 2019 and, voila, I have my list of browsers back and Firefox is my default browser once again. Hallelujah.

    I read that one shouldn't defrag an SSD but some people think it is ok. Well, I thought, what could be the harm. It is harmful.

    Attention everyone: Don't fool with an SSD.

    Thanks to Edwin, CmmTech and all of you for your suggestions and help.

    Thanks for staying with the thread and posting the resolution seems some abandon the thread once their issue is resolved, if they'd just post what fixed it for them it will help others.

    Rep for doing that @dangnad2
