Selenium not working with Firefox 48

[Andrea Filippig]

Hi!

I wrote an application in C# that worked fine with Firefox 42, Win 7 64bit, selenium server 2.47.1. After upgrading to Firefox 48 it dod not work any longer. Upgrading the server to 2.48.2 didn't solve, only downgrading to Firefox 42.

What should I do to use Selenium RC with Firefox 48?
Thank you for any help!

The latest version of FF is 43 http://prntscr.com/9mamyi .

I had problem with Selenium WebDriver and Firefox 43. I solved it with selenium update http://prntscr.com/9mai8o .

Try that combination.

I used the chat room about this and they said to re-download the new build. Files date stamp is for 7Jan16. Now I just have to remember how to install it ....

However, you should note that Firefox Driver will not work from version 45... see this thread as you should be aware... https://groups.google.com/forum/#!topic/selenium-developers/e_y4SyhZHX4

works for me on windows 7, 64-bit for Firefox mozilla browser with latest and greatest version of Selenium jar files, i.e., 2.49.1

FirefoxProfile ffprofile = new FirefoxProfile();

ffprofile.setPreference("xpinstall.signatures.required", false

WebDriver driver = new FireFoxDriver(ffprofile)

P.S.: i believe latest and greatest version of Mozilla Firefox browser is 44 :)

Hi,

good to check change logs of selenium to know which browsers that jar version fits for.

Thank You,

Hi I am also seeing this issue.  I am using Selenium2Library (python and robot framekwork) and am getting the following error:  "selenium.common.exceptions.WebDriverException: Message: Can't load the profile."  I am guessing it has to do with the new "Electrolysis" changes but I was hoping that you had found a way to work around this without downgrading. 

Thanks, 

Justin

The old Firefox Driver no longer works with Firefox 48+

You can use Firefox 47.0.1 and set it to not update, or use the Extended Support Release (Firefox 45)

To use Firefox 48+ you need to use the new Mozilla geckodriver with Marionette: https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver

Selenium 3 is available in beta now defaults to using Marionette.

Technically Selenium FirefoxDriver should work with Firefox 48 if you
disable e10s (multiprocessing) and use an unbranded build, such as
DevEdition or a custom build. This is because 48 also ships with
add-on signing, and FirefoxDriver isn’t signed.

I came across this thread fairly early in my search to uncover issues relating to the use of Selenium with Firefox.

The Compatibility page located here is sadly out of date (I'll see about making a PR):

http://www.seleniumhq.org/about/platforms.jsp

To clarify Titus's point Firefox+Selenium will only work up to version 47.0.1 when using these versions of the various pieces of software:

- Firefox 47.0.1

- selenium-server 2.53.1

- selenium-firefox-driver 2.53.1

Hope that helps others. :)

I am a QA tester trying to navigate the dev's world and if I understand this, selenium is an open source company.   Why would a company pick selenium as a web-driver when the company has no leverage to bug ticket the group to make their software fricking work with the latest version of a browser.  I guess "you get what you pay for".  Meanwhile, employees trying to make progress with automated scripts are blocked from making progress and aren't geeky enough to figure out what additional file or whatnot to update to just get their scripts working

Doug,

First things first. Selenium is an open source library that was created by a bunch of volunteers and open source enthusiasts who are trying to do their bit to make a difference in their free time without being paid.

A company would pick Selenium as their web automation tool for maybe the following reasons :

1. Selenium is open source and there is no license cost involved.
2. Getting a resource familiar with selenium is relatively easy when compared to get skilled professionals who are conversant with paid tools.
3. Whenever there is an issue with the automation tool itself, the QA engineers are presented with an opportunity to go ahead and attempt at fixing their problem on their own, instead of waiting for some company to fix their problems.

With respect to your problem on not being able to work with Firefox 48, you can always roll back to Firefox 47.0.1 and make use of Selenium 2.53.1.

Things would be fine.

Currently Firefox is going through a transition phase wherein a lot of internals within Firefox are changing now.

You can find more information about those changes from the Selenium core dev folks themselves in these threads 

• http://stackoverflow.com/a/38917100/679824
• https://groups.google.com/d/msg/selenium-users/rSX16EUIbFw/KslP2AHHAAAJ

​Lastly, Selenium RC is obsolete. There is no maintenance that is going carried out on those APIs. So please start migrating over to using Selenium WebDriver APIs.​

Thanks & Regards

Guys,

My understanding is that in theory any new release of Firefox (or another Browser) may not be 100% compatible with the latest version of the relevant Webdriver. 

This lack of compatibility could manifest itself as either slight behavior changes when interacting with the browser or the test may fail to run at all. 

In the case that the new browser version causes the test to fail to run, the usual resolution is to revert to the previous version of the browser so Webdriver can run again. 

How then can we ensure our apps are running ok on the latest browser (where there is a higher probability of a bug being introduced)? 

We can wait until Webdriver 'catches up' with the latest browser version but what if that is not for a few more weeks/months? 

Would I need to test my apps manually on the new browser until Webdriver catches up? 

[Titus Fortner]

At this point, every single browser vendor is developing their own driver for their browser. There will be no need for Selenium to "keep up." Selenium will handle the commands to the driver, and the driver will keep up with the implementation of the browser. Firefox 48+ requires Mozilla's geckodriver. If you want to keep using the Selenium-built legacy driver, you should stick to Firefox ESR (45) or 47.0.1.

Hi Nathan,

I'm totally new to Selenium and Firefox.  I currently have Firefox 49.0 and Selenium 2.9.1.
What is the best way to downgrade to FF 47.0.1 and SL 2.53.1?  Do I need to remove Firefox and install again?

[Shubham Agarwal]

Hi Linda,

You can run your scripts with firefox 42.0 and selenium 2.53.1 or selenium 3.0 beta , I have already done it.
