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?

I tried several versions of Firefox. It looks okay to me

I called for more help.

You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data for that website will be saved once again.

Can you attach a screenshot?

• use a compressed image type like PNG or JPG to save the screenshot

Here is the screen shot, it will just sit there like this for hours. Works right away on my phone and in Chrome.......

forgetting the site does not work either

I notice that you have Adblock Plus and that it is blocking content.

Try to uninstall ABP to see whether that has effect.

Try uBlock Origin as a replacement for ABP to see if that works better.

I tried it with no add-ons turned off and same thing happens

You can create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
