MacOS Sequoia 15.7.7; Firefox 141.0.2

The "one sentence" in the heading states the problem. I am unable to use Firefox. Using Safari to make this post.

Firefox loads. It opens windows (I had fourteen open when I last used it successfully; I have many, many tabs). Then it removes each window from the screen. Firefox is in the Menu bar, but no windows are displayed. The windows still show in the list when selecting Window in the menu bar. Selecting a window in that list has no visible effect. File>New Window opens a new window, which works as expected. With one new window open, File>New Window opens a second.

Typing a few characters in the address bar opens a dropdown with a list of tabs, each with the affordance, Switch to Tab. Clicking on one takes down the list but does not open a window.

I would like, for a start, instructions on how to use Firefox starting afresh with no windows. First: having set aside the data that causes this problem. I suppose that might be simply a new profile. But would like instructions from a person interested in pursuing the problem with me while I continue with the rest of my life.

I'm willing to delete some data from the failing profile, is there is reason to do that, but would like to preserve at least a list of the URLs of the tabs of the windows. Or to learn how to see those in the profile data.

I see four profiles: 

  <garble>.default-<13 digit integer>  Date Modified: Today  2.2 GB
  <garble>.Default Profile   Date Modified: Last June   24.6 MB
  <garble>.default-release-1   Date Modified: Last June, five minutes later  93.2 MB
  <shorter garble>.default-release   Date Modified: 2021   13.4 MB

It has been my practice with Firefox and Thunderbird to install and then to create a new named profile for use. But, as you see on the first line above, I did not assign a meaningful name.

If requested, I will post again from a new Firefox window, selecting Share Data.

Thanks in advance.
