Selenium Python - Advanced Patterns

Identify the issue in this Selenium Python Firefox profile setup for downloading files:

from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.set_preference('browser.download.folderList', 2)
profile.set_preference('browser.download.dir', '/home/user/downloads')
profile.set_preference('browser.helperApps.neverAsk.saveToDisk', 'application/pdf')
profile.set_preference('browser.download.manager.showWhenStarting', false)
profile.set_preference('pdfjs.disabled', true)

AThe 'browser.download.dir' path should be an absolute path string, which it is.

BNo issues; the code correctly configures Firefox profile for auto-download.

CThe 'pdfjs.disabled' preference should be set to false to disable PDF viewer.

DThe 'browser.download.folderList' value should be a string '2', not an integer 2.

Step-by-Step Solution

Solution:

Step 1: Check 'browser.download.folderList'
Value 2 (integer) is correct to specify a custom folder.
Step 2: Verify 'browser.download.dir'
Must be an absolute path string; '/home/user/downloads' is valid.
Step 3: Validate 'pdfjs.disabled'
Setting it to true disables built-in PDF viewer, which is correct for auto-download.
Step 4: Identify the bug
All preferences are correctly set; no bug present.
Final Answer:
No issues; the code correctly configures Firefox profile for auto-download. -> Option B
Quick Check:
Integer 2 is valid for folderList, path is absolute, PDF viewer disabled [OK]

Quick Trick: Integer 2 is valid for folderList; path must be absolute [OK]

Common Mistakes:

Using string '2' instead of integer 2 for folderList
Setting pdfjs.disabled to false instead of true
Using relative path for download.dir
