According to this answer https://stackoverflow.com/a/72793082/2554330, there are some bugs in the latest version of chromedriver that have been fixed in the version that works with Google Chrome Beta, so I'd like to try the beta.
This answer https://stackoverflow.com/a/65975577/2554330 shows how to run Google Chrome Beta from Javascript. I'd like to do the same from RSelenium, but I can't spot an equivalent of chrome_options.binary_location.
How do I specify the Chrome location when using RSelenium?
Try following codes:
cPath <- "C:/Program Files (x86)/Google/Chrome/Application/chrome.exe"
ecap <- list(chromeOptions = list("binary" = cPath))
remDr <- remoteDriver(browserName = "chrome", extraCapabilities = ecap)
remDr$open()
Note that startServer() func is now defunct.
These were obtained from this comment by the author of RSelenium.
Try this, the chromedriver is wherever you place it and the beta browser is wherever it gets installed. It's been a long time since I used r/selenium, so slashes maybe the wrong way
require(RSelenium)
RSelenium::startServer(args = c("-Dwebdriver.chrome.driver=C:\\Users\\me\\Documents\\chromedriver.exe")
, log = FALSE, invisible = FALSE)
remDr <- remoteDriver(
browserName = "chrome",
extraCapabilities = list("chrome.binary" = "C:\\Program Files\\ChromeBeta\\chrome.exe")
)
remDr$open()
head(remDr$sessionInfo)

I would like to use firefox portable with the RSelenium package.
I tried to use the following command seeing commands from other browsers without success.
library(RSelenium)
ecap <- list("moz:firefox.binary.path" = "mozilla-firefox-portable-98-0-1.exe",
"moz:firefoxOptions" = list(args = list("--headless")))
rD <- rsDriver(
browser = "firefox",
extraCapabilities = ecap,
port = 4580L)
Thanks for any help!
i'm trying to open this page in firefox using RSelenium and it throws me the error SEC_ERROR_UNKNOWN_ISSUER.
library(RSelenium)
rD <- rsDriver(verbose = TRUE,
port=3490L,
browser=c("firefox"),
geckover = 'latest',
check = TRUE
)
remote_driver <- rD[["client"]]
remote_driver$maxWindowSize()
remote_driver$setTimeout(type = "implicit", milliseconds = 100000)
remote_driver$setTimeout(type = "page load", milliseconds = 100000)
remote_driver$navigate("https://www.farmaciasahumada.cl")
I added the server certificate error exception in firefox, and I still can't get into the site.
I saw that this problem can be skipped in python or java, but I have not found any solution for R.
With other browsers I have no problems.
I hope someone can help me:(
I can load the page in firefox,
library(RSelenium)
driver <- rsDriver(browser=c("firefox"))
remDr <- driver$client
remDr$navigate("https://www.farmaciasahumada.cl")
Try chrome, update your package and web browser.
How can image downloading be disabled when using Firefox in Rselenium? I want to see if doing so makes a scraping script faster.
I've read the Reselnium package manual including the sections on getFirefoxProfile & makeFirefoxProfile.
I've found this link that shows how to handle chromedriver.
I can disable images for a Firefox instance that I manually open in Windows 10 but Rselenium does not appear to use that same profile.
Previously you would need to set the appropriate preference (in this case
permissions.default.image) however there is now an issue with firefox resetting this value see:
https://github.com/seleniumhq/selenium/issues/2171
a work around is given:
https://github.com/gempesaw/Selenium-Remote-Driver/issues/248
implementing this in RSelenium:
library(RSelenium)
fprof <- makeFirefoxProfile(list(permissions.default.image = 2L,
browser.migration.version = 9999L))
rD <- rsDriver(browser = "firefox", extraCapabilities = fprof)
remDr <- rD$client
remDr$navigate("http://www.google.com/ncr")
remDr$screenshot(display = TRUE)
# clean up
rm(rD)
gc()
In web browsers it is possible to clear history.
How is it possible to clear history in firefox browser in RSelenium using R commands?
See Possible to disable firefox and chrome default caching?
In RSelenium and firefox you could pass as follows:
fprof <- makeFirefoxProfile(
list(
"browser.cache.disk.enable" = FALSE,
"browser.cache.memory.enable" = FALSE,
"browser.cache.offline.enable" = FALSE,
"network.http.use-cache" = FALSE
)
)
remDr <- remoteDriver(extraCapabilities = fprof)
remDr$open()
Using RSelenium to open a site like this:
require(RSelenium)
RSelenium::startServer()
remDr <- remoteDriver(browserName = "chrome")
remDr$open()
remDr$navigate("http://www.adobe.com/") #the site is just an example
What command should I use to take in R the results of window.s_adobe?
You could try something in the veins of
res <- remDr$executeScript('return window.screenX;')
