Make Selenium RC run on FF 5

by on in
After upgrading from FF 3.6 to FF4 or 5...your selenium RC scripts  not running on FF.?


Here is the solution for that...

You need to do a simple thing..you have to Upgrade the old selenium-server file....to selenium-server-standalone-2.0rc3.

Here is the new server file New Selenium Server Jar File

Then replace the old file with new server file in eclipse..then restart your eclipse...Now your old scripts will run in FF4 or FF5.

    Yeah, Thank Guys it works!

    If you want to use it for tapestry-tests, you have to exclude the old selenium-server version and add the new 2.0rc3 Version!

    Also to add, Selenium 2.0 rc3 does NOT work fine with BEA jrockit 1.5, jdk 1.5.. Recommend using JRE6.

    I am new to selenium, using selenium server2.3 and FF5 and I am not
    creating any custom profile for firefox5.Testing our application(web-
    based app).
    Issue:
    I constantly get stuck up with
    "com.thoughtworks.selenium.SeleniumException: ERROR: Threw an
    exception: Security error" when executing only a certain set of
    javascripts and there is no detailed explanation about this security
    Error, but the same works fine when i change the browser type from
    *firefox to *firefoxproxy.
    Note:When i tried to run the same set of javascripts through the
    javascript interpreter from the browser(FF5+Firebug) opened from
    selenium, i get successful results(No security Error)
    1.Not able to find the root cause for this Security Error.??
    2.I am not able to get the actual difference between *firefox and
    *firefoxproxy ??
    3.If i use *firefoxproxy as browsertype ,FF5 crashes when I run
    multiple test cases.!
    Kindle help me.! Even if it is a work around.!

      u can use, but the FF13 will not work with server-standalone-2.19.0. go for server-standalone-2.25.0.

    Hi Has anyone worked with Selenium RC and firefox 6.0. I am trying to run my selenium RC script again firefox 6.0. It just launches firefox and then remains Idle.

    I already upgraded my JRE version to 1.6.0_21 and selenium jars to 2.0. But didnt help much.

    Any thoughts ?

    Why doesn't it work with selenium-server-standalone 2.0.0 or 2.5.0?
    I use DefaultSelenium.

    The FF5 window opens, but nothing happens.
    It seems like the window to control the browser is not being opened like with FF 3.6

    Thanks
