When I open a Facebook page from Thunderbird Mail, some videos have the usual "triangle" to click on (these are OK) and there are other videos that have a "flashing three lines", these I cannot open.
The other problem is a black bar at the top of the open Facebook page. Again, this page is opened from Thunderbird Mail. At the top of the black bar the menu bar from Firefox is showing up in grey type color.
I hope the above info is enough for one of you guys to put me on the right track to fix these irritating issues.
I am running on Win 8.1 on a Dell PC. It is about 18 months old and to date I have had very few problems.
As far as I can determine, we had a power failure, the PC shut down (normal) and these issues were observed after bringing the machine back on line. I also had an issue with Adobe Flash in Firefox. However i seem to have corrected that issue.
Please help this old bloke from the UK
