Selenium no longer works in R

[Befrancesco]

Good evening, I write this question because I have a problem with my Rselenium. I use selenium with R every day, but since yesterday it has stopped working. My code is:

library(RSelenium)
driver <- rsDriver(remoteServerAddr = "localhost", port=4445L, browser=c("firefox"), version = "latest")

The error message is:

  },

Could not open firefox browser.
Client error message:
     Summary: SessionNotCreatedException
     Detail: A new session could not be created.
     Further Details: run errorDetails method
Check server log for further details.

The real problem is that before yestarday the script worked.

The versions about the tools are:

Java is 1.8.0_221-b11

RStudio is 1.2.1335

Firefox is 69.0(64bit)

Windows 10 Pro 64bit

I didn't change my code. I don't know what happened?

Thank you so much in advance for any tipy of help.

Does it work for you with

library(RSelenium)
rmDr <- remoteDriver(remoteServerAddr = "localhost", port=4445L, browserName = "firefox")
rmDr$open()

? Are you using a Docker Selenium standalone-firefox?

[Befrancesco]

Thank you for your answer. Yes, I tried and used in my script the code that you wrote, but it didn't work. I tried to change the version of firefox, but nothing.

In the end I solved the problem through the package Reticulate with python.

I think that this problem, maybe, is windows update's fault (but is just my thinking, I don't have the proves).

[Nosferican]

I echo the documentation suggestion to have the remote server as a Docker standalone which should eliminate all the architecture/OS/version infrastructure issues.

Okay, thank you. I will do and I will post here the results ( I hope soon!)
