1294488 - Rules inspector is blank on my site when running on localhost

Status: RESOLVED INCOMPLETE

(DevTools :: Inspector: Rules, defect, P3)

Description

[Stephanie Hobson [:shobson]]

When debugging my site locally the rules inspector is always blank.

Steps to reproduce:
1) You can download and install the site from here: https://github.com/mdn/viewsourceconf it happens with both the docker and node dev environments.
2) open element inspector
3) click on an element with a class
4) rules inspector is blank

[Julian Descottes [:jdescottes]]

I cannot reproduce this issue for now. What I tested:

- cloned https://github.com/mdn/viewsourceconf
- npm install
- node build dev
- go to http://localhost:8080/berlin-2016/
- open the inspector, inspect some elements with a class

I tried both on release, dev-edition and Nightly (all 3 on OSX if that matters).

Can you try with in a private navigation window and with a clean profile?
Thanks.

I'm sorry, I don't have time to create a clean profile. It doesn't happen for me in Dev Edition though, is that a clean profile?

Comment 3

[Loic]

DE uses surely its own profile, so if the issue is not reproducible in that case, your current profile is probably faulty.
Creating a new profile takes 2 min, you can test it if you want:

As Loic said it's really quick to test with a clean profile, but from what you said, it's probably profile related anyway.
Any add ons installed which might have an impact on devtools ? Can you :
- open about:support
- click "Copy text to clipboard"
- attach the information here

Thanks

Inspector bug triage, filter on CLIMBING SHOES. Assigning P3 for now, will reassess when we get more information.

2 minutes to restart the browser really underestimates the number of tabs I have open ;)

[Julian Descottes [:jdescottes]]

Thanks for posting the info!

So I tried installing the various addons listed here, but I still could not reproduce the issue.
Unless you identify the root cause on your side, I don't think we'll be able to investigate here.

Will you have time to do so?

I'm sorry, I don't have time to do more than copy and paste :(
