Ever since the update to Firefox 66.0.3, I have been getting frequent errors to the effect of "...sorry, we are having trouble finding this website". Sometimes, this error appears instantly after clicking on something as common as google.com... My AT&T e-mail account sometimes takes more than several seconds to respond... I quickly get this error. I rarely encountered this in the past; it happens way too frequently now.

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the ActiveX.

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}
