How can I override (Chrome's) SSL certificate issues?

Please stop using WinXP. No OS that is no longer receiving security updates is suitable for use on the Internet. It’s only a matter of time before such a machine is compromised, and spewing spam emails or DDOS attacks at the rest of us.

According to this site, “Chrome relies on the Windows certificate store. Unfortunately, it does not (currently) give any way of installing a certificate from a URL.” So, as you suspect, you won’t be able to fix this unless you can get a root cert update from your OS vendor. Please consider switching to Win7 or upgrading to Linux.

I also still use Windows XP and encounter the same problem, when I try to visit twitter, the similar messages occur. Luckily, Firefox browser allows me to access twitter.

Please stop using Windows XP, or Debian Sarge, or AT&T Unix SVR3, or Macintosh System 8, or any operating-system software which is no longer supported by the vendor.

It’s 2014, not 2002. There are plenty of cheap or free options available. Installing an operating system is not difficult. It’s certainly less difficult than recovering from an infected system.

A lot of people continue to use old operating systems after they’ve become obsolete. Not everyone can afford to buy a new machine every few years.

Neither of my machines supports Win7 and sorry, Linux (or Ubuntu which I have used on occasion) is not an operating system, no matter how many people pretend that it is. WinXP has been pretty stable for over a decade and unless I find something better for my current PC or can afford a new PC/OS combo, I’ll have to find ways of working around such problems. I do realise that eventually it will be a dead end for me, but hopefully until then there will be a decent option that is both user-friendly and affordable.

Thanks for everyone’s answer!

Installing a new OS does not require buying a new computer. If you don’t like Linux then that’s your prerogative, but it’s pure ignorance to pretend that it’s “not an operating system”. Perhaps you didn’t know that there are more total installs of Linux than there are of Windows?

Windows XP was pretty stable, because Microsoft supported it. In case you haven’t heard, that support has ceased. There are no more security updates for XP. What has not ceased is the ongoing efforts by crackers and criminals around the world to discover and exploit faults in XP. There is now a growing list of known, unpatched XP exploits. Most of these can be automated. It’s only a matter of time before your XP box is compromised; it’s likely to have happened already.

It was utterly pointless for you to have asked this question. The answer is, stop using your obsolete, unsupported OS in the context of the Internet. It is dangerous, it is irresponsible, and it is un-neighborly. There are plenty of options which are both user-friendly and FREE, but your own mulish obstinacy and ignorance prevents you from looking at them.

GOOD DAY.

@rexacoracofalipitorius I just upgraded a laptop from XP to 7. It was a disaster. It looks very pretty, but everything is slow and clunky, despite having lots of memory. It’s like trying to fit a square peg into a round hole… it simply doesn’t fit. Second laptop will continue to run XP until it dies.

I don’t surf unsafe sites, and am no risk to you whatsoever. But I’m sure you’ll judge me irresponsible and un-neighbourly just the same. I don’t care.
