Selenium work only with Firefox? If no similar to firebug which needs to be installed for IE and Chrome

Arun Motoori said...

@man - Though we can run Selenium Automation scripts on Firefox, IE, Chrome browsers, Firebug and Firepath addons are available only in Firefox Browser.We use the Firebug and Firepath addons in Firefox browser to identify locators and once the locators are identified in Firefox browser they even work on Chrome and IE browsers too.

Hello Arun,

Thank you for the details on selenium Automation tool.It is very detailed and easy to understand.
Is it possible to get a download copy of firebug? without downloading the addon from firefox and also without installing via firefox?
Due to user access restrictions at work I am unable to download or install the firebug on my test machine. Any suggestions in this please?

Thanks in advance.

Hi Arun,

I have installed 47.0.1 firefox browser. But firepath link your mentioned in above blog is no more helpful as that extension is removed by firefox developers.

Error received on that link::

Oops! We can’t find that page

If you’ve followed a link from another site for an extension or theme, that item is no longer available. This could be because:

The developer removed it. Developers commonly do this because they no longer support the extension or theme, or have replaced it.
Mozilla removed it. This can happen when issues are found during the review of the extension or theme, or the extension or theme has been abusing the terms and conditions for The developer has the opportunity to resolve the issues and make the add-on available again.

If you’ve followed a link on this site, you’ve have found a mistake. Help us fix the link by filing an issue. Tell us where you came from and what you were looking for, and we'll get it sorted.

Try visiting the page later, as the theme or extension may become available again. Alternatively, you may be able to find what you’re looking for in one of the available extensions or themes.

Arun Motoori said...

Yes Naveen. Now you have to use the alternative addons like ChroPath in Firefox and Chrome Browsers.
