Custom path to firefox.exe?

[luke-a]

How can I specify a custom path to firefox.exe and to geckodriver.exe using RSelenium? For example in Python, this works well:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary(r'C:\FirefoxPortable\App\Firefox64\firefox.exe')
executable = r'C:\...\geckodriver.exe'
firefoxProfile = FirefoxProfile()
browser = webdriver.Firefox(firefox_binary=binary, firefox_profile=firefoxProfile, executable_path=executable)

I believe one could specify both using the javaargs argument form startServer. However, I got no idea how to specify any of the paths in RSelenium::rsDriver or wdman::selenium. Thanks for any hints in advance.

@luke-a you can pass additional arguments to the JVM or to selenium via wdman for example:

commandOutput <- wdman::selenium(retcommand = TRUE, 
                jvmargs = list('--somejvmarg=somejvmvalue'), 
                selargs = list('--someselarg=someselvalue'))
# check what will be passed when running process
> commandOutput


> commandOutput 
[1] "C:\\PROGRA~3\\Oracle\\Java\\javapath\\java.exe --somejvmarg=somejvmvalue -Dwebdriver.chrome.driver=\"C:\\Users\\john\\AppData\\Local\\binman\\binman_chromedriver\\win32\\2.33/chromedriver.exe\" -Dwebdriver.gecko.driver=\"C:\\Users\\john\\AppData\\Local\\binman\\binman_geckodriver\\win64\\0.19.1/geckodriver.exe\" -Dphantomjs.binary.path=\"C:\\Users\\john\\AppData\\Local\\binman\\binman_phantomjs\\windows\\2.1.1/phantomjs-2.1.1-windows/bin/phantomjs.exe\" -jar \"C:\\Users\\john\\AppData\\Local\\binman\\binman_seleniumserver\\generic\\3.7.1/selenium-server-standalone-3.7.1.jar\" --someselarg=someselvalue -port 4567"

reading https://github.com/mozilla/geckodriver#firefox-capabilities it should however be possible to
set the location of the custom binary as an extra capability. Something akin to

rsDriver(browser = "firefox", 
         extraCapabilities = list(
           `moz:firefoxOptions` = list(
             binary = `/usr/bin/firefox`
           )
         ))

should work.

That's great, thanks so much - it worked:

# binman::list_versions("geckodriver")
selServ <- wdman::selenium(retcommand = FALSE, port = 4444L, check = FALSE, geckover = "0.19.0")
# selServ$log()
remDr <- remoteDriver(browserName = "firefox", port = 4444L, extraCapabilities = list(
  `moz:firefoxOptions` = list(
    binary = "W:/FirefoxPortable/App/Firefox64/firefox.exe" # FF v56.0.2 x64
  )
))
remDr$open()
