XPath Checker - add-on missing in new Firefox

(Petr IXI) #1

Hi, after upgrading to new Firefox version, I lost my favourite add-on for checking XPAths.
Here is web: http://slesinsky.org/brian/code/xpath_checker.html
Bellow on this page you can find Source code for old Firefox. (or directly here: http://slesinsky.org/brian/downloads/xpathchecker.tar.gz)

I would like to ask you, if there is possibility to rewrite/refresh/reconfigure this add-on for new Firefox. Is there somebody with more experience and try to look at it?

Note: I was writing to Brian Slesinsky, but he did not answer :frowning:

Personally, with the modern CSS selectors, I haven’t used XPath for a very long time. That could be the reason XPath Checker hasn’t been updated since 2005.

The new Firefox Web Developer tool provides good functionality for CSS Selectors.

WebExtension API doesn’t have the same access as the legacy API did, although I haven’t checked its code to see if that would be possible as a WebExtension.

Did you try to see whether there is an equivalent addon?


I am not sure about the features of the xpath checker.

maybe the needed features can be integrated in one of these working addons.
You could write to these addons providers whether they support this.

Just came across this post and thought I would help. Here is what you can do.

  1. uninstall Firefox or do the research so you can load a second version
  2. go here and load the older version of firefox https://ftp.mozilla.org/pub/firefox/releases/26.0/win32/en-US/

This version supports 4.4.1 of xPath checker. I then went and did a few help>abouts to upgrade and went through a few updates and I am up to v47.0.2 and xpath checker still works. You can keep updating and see if it stops but I am good with this lol.

Hi xDazedx,

thank you for your reply. If I remember correctly, Firefox v47 was the last one, where it worked. Now we have v58 and I really do not want to use older versions of Firefox (but of course I thought about it as workaround).


FYI, it still works with 56.0.2. I really do miss it though. I still use FF 54.0.1 with it so I can still use selenium ide.

They are working on a new ide for the latest version of firefox, but it’s slow going. Without the xpath checker addon, it will be a real pain. Firebug used to let you type an xpath to test it if you didn’t have xpath checker, but the new inspector doesn’t… or doesn’t appear to.

A lot of the addons for quantum are awful compared to the old ones due to the new security enforcements.

Help, the extension can no longer be downloaded from firefox add ons website - https://addons.mozilla.org/en-US/firefox/addon/?id=1095

Does anyone know where else I can get it? It is hands down the best xpath extension out there still today. Nothing else comes close, I have tried all the alternatives and they are just horrible to use or don’t work with my firefox (ESR 52.9.0 64-bit)

The homepage is still up: https://code.google.com/archive/p/xpathchecker/. You may be able to build it from source code, or fork it.

Yeah I got the source code, but I’m not technical enough to turn that into a working extension myself.
