FF version 59.0.3 kaspersky internet security suite

of late, when a new version of firefox comes out they break something.

i am seriously thinking of chrome - heaven's forbid - but at least it works.

so any help to resolve this issue would be great before i enter the evil chrome empire :-(

since firefox updated to the above version i get the following error messages on some major websites, like bbc.co.uk, wikipedia, and others, some websites work, i have added some as exclusion but other websites don't give me the option.

the websites work in the Edge browsers ok.

some website sort of work, they just display strangely, mainly text and very little formatting at that.

i have set kaspersky to not scan encrypted connections in the network section, but that stop the mymoney protected browser from kaspersky from working!

i seem to spend more time getting firefox to work after an update, i'm at the point now where i just can't be bothered anymore.

i have cleared caches and other things i have seen as suggested fixes.


firefox states...

Your connection is not secure

The owner of en.wikipedia.org has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.


the advanced tab displays

en.wikipedia.org uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported.

Error code: SEC_ERROR_UNKNOWN_ISSUER

clicking on the error message gives the certificate info

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.

thanks for this but unfortunately i had tried all those things without success but thanks for the help.

i updated version 60.0 last night after i posted but that didn't change anything.

another post suggesting deleting cert8.db cert9.db and this appears to have solved the issue.

i assume the files must have been corrupt.

thanks

removing cert9.db and cert8.db

seems to have solved it.

now on version 60.0

thanks for the help
