Solved python firefox beautifulsoup python-webbrowser

I am trying to build a utility function to output beautiful soup code to a browser I have the following code:

def bs4_to_browser(bs4Tag):

    import os
    import webbrowser

    html= str(bs4Tag)

    # html = '<html> ...  generated html string ...</html>'
    path = os.path.abspath('temp.html')
    url = 'file://' + path

    with open(path, 'w') as f:
        f.write(html)
    webbrowser.open(url)
    return

This works great and opens up the HTML in the default browser. However I would like to set the path to a portable firefox executable which is at:

F:\FirefoxPortable\firefox.exe

I am using win7. How to I set the path to the portable firefox executable?

I remember you've used selenium for this. Why are you switching to webbrowser? – Communitarian 15/9, 2014 at 13:59

regarding #25736991 , thanks for your help on that Alex. I was not able to get it working using selenium perhaps related to firefox browser/webdriver incompatabilities. This seems to be working immediately – Cedilla 15/9, 2014 at 14:10

You could start your portable Firefox directly with the url as an argument instead.

from subprocess import call
call(["F:\\FirefoxPortable\\firefox.exe", "-new-tab", url])

My only question on this is I would like to open a new tab each time rather than an entire new browser. the webrowser module does appear to allow control of tabs – Cedilla 15/9, 2014 at 14:32

List of available Firefox command line arguments, should work with -new-tab – Rustproof 17/9, 2014 at 6:22

I know the question is old but here a code working with webbrowser and Python 3.11

myfirefox = webbrowser.Mozilla("F:\\FirefoxPortableESR\\FirefoxPortable.exe")
myfirefox.open(url)

As you will see, it works even if the .exe is not the "real" firefox.
