Firefox Support Forum

I tried to play a program on the CBS site; I've done this two or three times a year for many years with no problems, but this time the site said it could not load its ads (error 113), and therefore would not play the show. I've always watched the ads before, never a problem until now. I checked the icon for Adblock Plus, and it said that something had caused it to reset to default; it said I could fix this by removing and reinstalling Adblock Plus, which I did, but that made no difference. I don't know what default is, or what I had before (a friend set up my computer for me, so I don't know details), but I just want the CBS site to be able to load its ads so I can watch the program. What do I do? Thanks.

Hi all,

while playing (or better "fighting"...) with a linux docker container on Win10/WSL2/Ubuntu for using the MS spfx tool chain, I generated a SEC_ERROR_REUSED_ISSUER_AND_SERIAL in FF85.0/Win10 by first setting up a certificate exception for a dev-cert (https://localhost:4321) and then have the certificate re-created.

As described the support article [https://support.mozilla.org/en-US/kb/Certificate-contains-the-same-serial...], I removed all certificate exceptions for localhost:* and deleted the "gulp" authority in options/security/certificates.

Unfortunately, the SEC_ERROR_REUSED_ISSUER_AND_SERIAL persists even after a restart of firefox.

Any help is very much appreciated...

Thanks & greetings Markus Fehn

- I have no add-ons - always use private browsing is off - delete cookies is off - ask to save logins and passwords is on (I can save passwords all I want, but when I restart my computer, they won't be there.)

I can't find any info already asked about this - I'm running version 84.0.1

Help! I'm about ready to switch browsers..

Hello, I have forgotten my administrator password on my home computer and find that my printer has now disconnected. How can I reset this special password? Thank you

I restarted Firefox to update it and now get this error when I try to access google.co.uk

Secure Connection Failed

An error occurred during a connection to www.google.co.uk. You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

CBS.com insists that I have ad blockers installed. I do not as far as I know. Is there some default setting that CBS reads as an ad blocker?

bold textI am trying to access NJ state schedule vaccination appointment. Keep getting message that firefox will not allow me to access site. How to I change settings to do so.

I'm trying to remove my master password but when I go to settings to remove it and enter the password (the one that works for my main account), the "OK" button is ghosted out and I can't click it.

In short, the password that gets me into the account that allows me to post on this site isn't the "master password" and I can't recover the "master password".

Thanks for the help!
