Uncaught TypeError: c.querySelectorAll on every page

[AaronLavers]

Please read the CONTRIBUTING guide before submitting an issue.

Description

When Ghostery extension is enabled in Chrome 75.0.3770.100, every page returns a massive string of identical errors:

content_script_bundle.js:16 Uncaught TypeError: c.querySelectorAll is not a function at MutationObserver.<anonymous> (content_script_bundle.js:16)

The script it's experiencing the error in appears to be related to Cliqz - which appears to be a browser that I don't have on this machine.

Expected Behavior

I'd expect these errors to not be present, before today they did not appear.

Actual Behavior

On some pages where dynamic content loads in lists, this error can duplicate itself thousands of times.

Steps to Reproduce

1. Go to any website in Chrome with the Ghostery extension running

2. Open console

3. The error will be present

4. When the plugin is paused or disabled and the page is reloaded, these errors are not present

Versions

• Browser: Chrome Version 75.0.3770.100 (Official Build) (64-bit)
• OS: Windows 10 Creator

I get the same error on macOS Mojave and the same chrome version.

Hi @AaronLavers @VdeJong, thanks for your report. We were able to identify and fix this issue and we will ship it with an update ASAP.

Hi @remusao. Any thoughts on when the fix will be shipped? :)

[remusao]

@MarkoSulamagi, the fix was tested and released upstream in browser-core and now needs to be shipped via a new Ghostery extension release. @christophertino will know better about the precise release schedule.

I'm going to remove ghostery for now till the fix is released. I'm a web dev and can't work if errors are popping up in the console constantly.

[Jormosaurusrex]

Please, please fix this. It makes my work almost impossible.

Any update on the update @christophertino?
Have to agree with @kaiwa and sadly have to deactivate ghostery until the fix is released.

[christophertino]

@simoozzay We are scrambling to squeeze a few more bugs into this release and then hopefully get everything into testing tomorrow. Apologies for the delay.

[AaronLavers]

Appreciate it guys :)

[simoozzay]

Btw, for the webdevelopers using chrome. You can filter out the console errors in the meantime with a right click:

For the frontend developer who are suffering not visible your elements,
I had same issues c.querySelectorAll is not function.....
however In my case, problem was my whole

elements has class start with 'ad' display none.
after I change class name start with keywords 'ad' to something like 'co' or 'biz'
problem fixed .

I know it's just tricky solution, but hope this might help some developers
