webdriver.FirefoxProfile(): Is it possible to use a profile without making a copy of it?


As the documentation states, you can call webdriver.FirefoxProfile() with the optional argument of profile_directory to point to the directory of a specific profile you want the browser to use. I noticed it was taking a long time to run this command, so when I looked into the code, it looked like it was copying the specified profile Problem is, it takes an extremely long time for the profile to copy (something like >30 minutes, didn't have the patience to wait for it to finish.)

I'm using a hybrid of userscripts and selenium to do some automation for me, so to setup a new profile every single time I want to test out my code would be burdensome.

Is the only way to change this behaviour to edit the firefox_profile.py itself (if so, what would be the best way to go about it?)?


Solution

  • As per the current implementation of GeckoDriver with Firefox using the FirefoxProfile() works as follows :

    • If case of initiating a Browsing Session through a new Firefox Profile as follows :

      from selenium import webdriver
      
      myprofile = webdriver.FirefoxProfile()
      driver = webdriver.Firefox(firefox_profile=myprofile, executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
      driver.get('https://www.google.co.in')
      print("Page Title is : %s" %driver.title)
      driver.quit()
      
    • A new rust_mozprofile gets created on the run as follows :

      1521446301607   mozrunner::runner   INFO    Running command: "C:\\Program Files\\Mozilla Firefox\\firefox.exe" "-marionette" "-profile" "C:\\Users\\ATECHM~1\\AppData\\Local\\Temp\\rust_mozprofile.xFayqKkZrOB8"
      
    • Of-coarse on a successful closure (i.e. successful invocation of driver.quit()) the temporary rust_mozprofile.xFayqKkZrOB8 gets deleted/destroyed completely.

    • Again in case of initiating a Browsing Session through an existing Firefox Profile() as follows :

      from selenium import webdriver
      
      myprofile = webdriver.FirefoxProfile(r'C:\Users\AtechM_03\AppData\Roaming\Mozilla\Firefox\Profiles\moskcpdq.SeleniumTest')
      driver = webdriver.Firefox(firefox_profile=myprofile, executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
      driver.get('https://www.google.co.in')
      print("Page Title is : %s" %driver.title)
      driver.quit()
      
    • Similarly a new rust_mozprofile gets created on the run as follows :

      1521447102321   mozrunner::runner   INFO    Running command: "C:\\Program Files\\Mozilla Firefox\\firefox.exe" "-marionette" "-profile" "C:\\Users\\ATECHM~1\\AppData\\Local\\Temp\\rust_mozprofile.2oSwrQwQoby9"
      
    • Similarly in this case as well on a successful closure (i.e. successful invocation of driver.quit()) the temporary rust_mozprofile.2oSwrQwQoby9 gets deleted/destroyed completely.

    • So the timespan you are observing is the time needed for a FirefoxProfile() to scoop out a new rust_mozprofile.

    Perhaps as per your question timespan for profile to copy (something like >30 minutes) is a pure overhead. So it won't be possible to use a Firefox Profile without making a copy of rust_mozprofile.


    Solution

    • Upgrade Selenium Client to current levels Version 3.11.0.
    • Upgrade GeckoDriver to current GeckoDriver v0.20.0 level.
    • Upgrade Firefox version to Firefox Quantum v59.0.1 levels.
    • Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
    • Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
    • If your base Firefox base version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Firefox Quantum.
    • Execute your @Test.
