How can I customize url and search fields to remove the search engine dropdown, and ideally make the URL fields ONLY work with URLs and the search field only work with my default search engine?
A recent update has completely broken my muscle memory: I'm used to typing Cmd-L to move to the URL field, then a single tab to move to the search field, where I immediately start typing.
Now, that single tab moves me to the search engine dropdown, which I don't even want to use, so every time I try to search I have to stop and back up and it's badly affecting my workflow.
How can I either change the tab order or just get rid of the dropdown completely? If I want to use a different search engine, I can always just go to their page instead of using the search bar.
Also, is the URL field now exactly the same as the search field? I really want them to behave differently - I don't want to touch search if all I'm doing is re-visiting a URL in my history. Is there a way to have a URL field that ONLY works with URLs and avoids search, and a separate search field that works with my default search engine?
Thanks for your help.

Some background: Firefox (and many other apps) were running fine, then late yesterday afternoon (but I haven't had time to look at it until now) my laptop started swapping heavily, and after waiting for some time for it to become usable, I gave up and held the power-button down for long enough to make the computer turn off. Then I waited some seconds and pressed the button to turn it back on. Things seem to work, except that firefox won't start normally.
What happens now: When I start it by executing `firefox-esr` from a terminal, it dies (the terminal just displays "zsh: killed firefox-esr"), if I then try to start it again, it open a dialog saying the was some problem (didn't note down what it said precisely) and that I could start it in safe mode, when I accept that, firefox opens with a page saying it couldn't restore my session (it talks Danish) and offers to start a new or restore the session, when I clcik that (I've never known it not to work) it opens windows and tabs that looks like what I had. It does not open a dialog like the one shown on: https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode?as=u&utm_source=inproduct
Instead of spending a lot of time troubleshooting. I thought I would just go for a full refresh, so I found: https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings
but following that doesn't work! I can follow the first two steps (i.e. clicking the menu and select "Help" and "More troubleshooting information". That opens a new tab on "about:support", but that does not have a "Refresh firefox" button on the right side of the page as described.
The "Copy text to clipboard" button on that page does not copy anything, but the "Copy raw to clipboard" puts the data that is shared below on the clipboard.

I am finding Firefox to become less user friendly as time moves on. The latest is that my 1Password 6 app is no longer able to paste my Passwords into the fields on a Web Page. This has become too frustrating, and I cannot imagine why Firefox would do something like this.

How can I prevent other sources from bypassing my Firefox/Mozilla downloads and installations? I once had a secure Firefox account. Now every time I update or reinstate there is a possibility that it will be violated in the future without my direction or approval? HELP
