I can't reproduce this bug with Firefox 47, I see that you are using Firefox 45, are you using the Extended Support Release version of Firefox? If not can you update to 47 and check again? Thanks

Yes, I am on 45.2.0 ESR.

I have actually had quite a few similar issues with this version anyway so I will give 47 a go.

As a point of information, has the Nightly version from 16th May (when I was looking at bug 1272465) found its way into a release version yet?  (/where would I find this info)  Would this be 47?

Thanks

47 did nothing so I restarted in Safe Mode and problem wwent away; same with 45 ESR.  Tracked it to the Avast Online Security Extension (10.3.3.44) which when disabled makes the problem go away.  Presumably this needs reporting to Avast - or does Firefox have a communication channel open to Avast?

Hello Reporter, This is a known issue. Please see the following link for more information

Comment 5

[Cliff_G]

OK, thanks, I think I see; I now notice that the response failure occurs when the browser jumps from http to https. (Also see https://www.avast.com/en-gb/faq.php?article=AVKB190 - though nothing specific re. Firefox there).  But my FF has the Avast certificate installed; the thread you flagged appears to suggest that once the Avast certificate is installed all is then OK.  

Do I need to do something else?

I am not sure this (Comments 4 /5 ) is the same problem.  If I disable https scanning in Avast the problem does not go away.  I have to disable the Avast Online Security / Reputation extension.

Mass-closing old Extension Compatibility bugs that relate to legacy add-ons or NPAPI plug-ins. If you think this bug is still valid, please reopen or comment.

Sorry for the bug spam, and happy Friday!
