hi, this may be caused if you have switched on tracking protection (do you see a shield icon on the left side of the address bar on affected pages?) or a filterlist that your adblocker is using...

Hey Thanks! So far so good with turning off tracking protection. We'll see if it holds for a few days before I declare problem solved.

Hi renics

Could you please start a new thread for your question?

Then you can provide more information like your operating system and installed extensions/plugins.

I notice a dot on the Control Center 'i' icon as an indication that you made changes to the default permissions. You can click the 'i' icon for more information.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block (wanted) content.

• make sure your extensions and filters are updated to the latest version

Firefox shows the shield icon at the left end of the location/address bar in case Content Blocking is blocking content.

• click the shield icon for more detail and possibly disable the protection

You can check the Web Console about what content is blocked

• "3-bar" menu button or Tools -> Web Developer

You can try these steps in case of issues with web pages:

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• hold down the Shift key and left-click the Reload button
• press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• press "Command + Shift + R" (Mac)

Clear the Cache and remove the Cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Remove the Cookies" from websites that cause problems:

• Options/Preferences -> Privacy & Security
  Cookies and Site Data -> Manage Data

"Clear the Cache":

• Options/Preferences -> Privacy & Security
  Cookies and Site Data -> Clear Data -> Cached Web Content: Clear

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

Tried everything you wrote did not help. Including with disabled add-ons in the browser in safe mode. (I notice a dot on the Control Center 'i' icon as an indication that you made changes to the default permissions. You can click the 'i' icon for more information.) Look at the screenshot, there are no locks. It all started after upgrading the browser to version 53. Everything worked before. And this happens only in two sites of RIA News and Tape ru News and nowhere else.

It says you're allowed to set cookies. And what is there to set cookies, if the page is empty as in the photo.
