Watir-Webdriver does not show dialogs in Firefox when finished testing - ruby

Question

I am using webdriver with FF38, but leaving the browser open window after my script is done. I find that dialogs no longer open in that window, if I continue after the testing.
The script is meant to automate forms input rather than doing it by hand, but the website does use dialog boxes to express choices -- (for example, deleting data that the script has just entered, so that I can rerun the script without overwriting information)
Is there a way to disconnect the webdriver dialog handling after I'm done?
I'm feeling a little foolish, but my searches haven't born fruit, so I may be using the wrong words in my search, given my newness to ruby and webdriver.
Example would be this:
require "watir-webdriver"
l_Browser = Watir::Browser.new :firefox
l_Browser.goto "http://www.w3schools.com/js/tryit.asp?filename=tryjs_alert"
# Click the button that opens the dialog
l_Browser.div(:class => "container").div(:class => "iframecontainer"). \
div(:class => "iframewrapper").iframe(:id => "iframeResult"). \
button(:onclick => "myFunction()").click
The result is that a popup will appear, but no popups will appear further attempts to click on the button once the script is done.
This includes even if no popup is triggered during the script (ie:, last line commented out)... Once the script is finished running, no popups appear in a watir webdriver opened window. (They will open if I click on the button while the script is running, but not after)
Based on the answer below, I am using:
begin
b = Watir::Browser.new :firefox
File.open('d:\\MARK.TXT', 'w') {|f| f.write(YAML.dump(b)) }
# Load MessageBox and wait here
b = YAML.load(File.read('d:\\MARK.TXT'))
ensure
if !b.nil?
b.close()
end
end
... but it currently allows for errors that can be ignored... I just don't know how wise it is to ignore them in the long run:

Answer 1

I learned something new answering your question: Turning an object into text is called serialization. Turning text into an object is called deserialization.
And here's a gist of you want to do, specifically.
The important part is
my_object = SomeObject.new
my_object.some_method # => returns your expected result
File.open('path/to/some.file', 'w') {|f| f.write(YAML.dump(my_object)) }
# Do whatever you want
my_object_reloaded = YAML.load(File.read('path/to/some.file'))
my_object_reloaded.some_method # => returns your expected result
You could even do this directly to your browser:
b = Watir::Browser.new
b.goto 'http://google.com' # => goes to Google
File.open('path/to/some.file', 'w') {|f| f.write(YAML.dump(b)) }
b = nil
# Do whatever you want, wait as long as you want.
# (Disclaimer: There are probably major limitations to 'as long as you want'.)
b = YAML.load(File.read('path/to/some.file'))
b.goto 'http://yahoo.com' # => goes to Yahoo

require "watir-webdriver"
l_Browser = Watir::Browser.new :firefox
l_Browser.goto "http://www.w3schools.com/js/tryit.asp?filename=tryjs_alert"
l_Browser.iframe(:id => 'iframeResult').button(:xpath => "//button[text()='Try it']").when_present.click # click on "Try it" button
l_Browser.alert.close # closing popup
