An Error Occurred During a Connection to www.google.com443.


I am using Firefox v3.6.21. I haven't updated to Firefox 4 or above because I strongly dislike the functionality and appearance of the new browser and toolbars. Therefore, I remain as above.

I also have a Google Toolbar used with Tabs. I love this dashboard appearance and ease of function; however, a couple of months ago there suddenly appeared an alert which read "An error occurred during a connection to www.google.com443. The OCSP server experienced an internal error. (Error code: sec_error_ocsp_server-error).

This alert now arises constantly online, opening tabs is problematic, slowed, and I have to constantly clear my cache and refresh until the error appears and I click ok. It then somehow clears the "clog" and most often opens the website. It has also begun to affect other HTML related programs by somehow affecting my POP-server.mi.rr.com (email server) connection.

I've contacted Google, I've tried various help forums, all to no avail. No information how to resolve this dilemma has been forthcoming.

See the links in the support article Google Toolbar is no longer compatible with Firefox - Here are some alternatives.

OCSP (Online Certificate Status Protocol) is used to confirm the status of a digital certificate. I wonder if the error you are seeing is because Google Toolbar is no longer being developed and thus the certificate's status has changed?

I haven't found a specific solution for you, but below are some options for you to try:

  • You could disable OCSP in Firefox, but this would result in it being disabled for all sites, which I don't recommend.

Finally, I recommend you also upgrade to the latest Firefox 3.6.x release - see here.

Hi! Thanks so much for your response. Yes, the error appeared after a Firefox upgrade to a new version several months ago; which, I can't recall, as Firefox is continuously upgrading! I just downloaded v3.6.21 today. I haven't gone towards Firefox 4 and the recent 5 . . . the reason being, I am addicted to the Google-type toolbar, familiar browser setup, tabs, bookmarks toolbar, etc. With the advent of Firefox 4 came the totally new and unappealing look of the toolbar and everything I hold dear and familiar! If you can suggest another browser or toolbar similar to Google, I'd be thrilled! :-)

Insofar as the OCSP problem, I totally agree that Firefox and the Google Toolbar are at odds and, that when Google announced it would not be supporting the toolbar any longer, boom! the OCSP error raised it's nasty alert. I will look into your suggestions, but I have little hope this problem can be solved to my satisfaction (as stated above).

Further, if I can further impose upon you to inquire if you have any updated suggestions to curtail incessant Internet Explorer Script Errors that have become prolific in my Outlook Express In-box. The latter are seen in messages with links or with graphics, but not all graphics.

To answer a question before it is suggested: Yes, I have opened the control panel, clicked on Advanced, and clicked on both "Disable Script Errors" side-by-side boxes, and also unclicked box below not to receive notifications of script errors.

Again, thank you!

I've made somebody happy, my job is done. :)

Please see the link here for suggestions of Firefox add-ons to replace the functionality provided by Google Toolbar.

Regarding Outlook Express, is Firefox set as your default browser? For instructions, see How to make web links open in Firefox by default.

I want to respond that, yes, my browser is Firefox and has been for several years. Insofar as the OCSP problem, I am just now beginning to follow you suggestions, which I consider to be very helpful and will result in my finding an acceptable resolution.

Thanks again! =:)
