I see you are using the beta version of the browser.

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}

Problem was still there in "safe mode" I shall review the articles you mentioned; I used the "turn off blocking temporarily" under the shield icon before I posted the question.

Are those CSS or JavaScript drop down menus ?

Did you check the Web Console for error messages ?

• https://developer.mozilla.org/en-US/Tools/Web_Console
• https://developer.mozilla.org/en-US/Tools/Page_Inspector/How_to/Examine_and_edit_HTML

It appears to be a CSS function. I checked the error message and see:

Request to access cookie or storage on “https://app.pendo.io/data/ptm.gif/4cfc5253-789b-470f-45eb-e4…Sjbz-mB2hJ0OWXCo5-waz679rhqOdh9vT7IqxV2LjzxslYazcL759BW8CRK_” was blocked because we are blocking all storage access requests. uux.aspx

Is that enough information?
