Hello I recenlty downloaded Firefox Quantam and having a problem using it, when i try opening google or anything associated with it (youtube, drive, docs etc.) it would not work, I would get a screen saying 'Did Not Connect: Potential Security Issue'. The error code is SEC_ERROR_UNKNOWN_ISSUER. Can someone help me out fix this problem? I like Firefox alot and it works much faster than google, this is the reason why i changed, also some websites work like Discord, Amazon, and some specific websites.

hi, a solution depends on the individual circumstances: under the error code SEC_ERROR_UNKNOWN_ISSUER there should be a "View Certificate" link, please click on it - what does the "issued by" section of this failing certificate say?

thank you!
