Blank Inspector CSS Rules pane on some sites e.g. https://github.com
Console output:

Code: Select all

I could be wrong but it sounds to me like ClearClick is just the messenger of a problem with that CSS rules viewer...

Does the CSS in that data: URI actually apply successfully to items on the page?

Yes. Page works fine. Problem only with Firefox DOM Inspector Rules pane.

I would suggest you try the latest Firefox Nightly and if the issue is present there, file a bug: https://bugzilla.mozilla.org/
It's easier for them to investigate if you get steps-to-reproduce starting from a clean profile. Also be sure to include a link to this thread.

If you file a bug, please post the bugzilla link here, thanks.
