All of a sudden, firefox could not connect

[Markfw]

I have been using this session for weeks 24/7. I was replying to a thread, and it locked up. I tryed edge, and it worked. Then chrome and it worked, but even after a cold boot firefox will no longer connect to the forums, any forum. I get:

Secure Connection Failed

The connection to the server was reset while the page was loading.

Run firefox -p, create another profile and see if you have the same problem?

OK< maybe stupid question, but in win 10, how do I do that.? run cmd, then in the black terminal, type "firefox -p " ?? It says

'firefox' is not recognized as an internal or external command,
operable program or batch file.

And why would this start happening right in the middle of a reply to a thread ?

 

[mikeymikec]

Right-click on the Start button and select 'Run', I think...?

 

[Markfw]

ok, well, at least it launched, but it still has the same problem. How do I create a new profile ? I don't want to loose all my saved passwords for other web sites though.

OK< somebody changed something, and it was not me. I just hit refresh, and now it all works again.

The other day I couldn't connect.

I ran CCleaner to clear my cache and everything worked fine. First time I ever saw that error.

When you run firefox -p from a run prompt, it will start the profile manager, which allows you to manage multiple profiles so you could test with one while leaving your main profile intact. This helps to narrow down whether the problem is profile-specific or something else.

It is not a browser problem or profile problem. It seems to be a problem of the web server.

I have the same problem occasionally with Seamonkey and with MS IE 11. Here is one possible error message in Seamonkey:

On other occasions, the error message offers a button for inspection of the certificate. On using that button, it says that the certificate cannot be loaded, or something like that.

I tried restricting the browser to a subset of the usually enabled TLS 1.0, 1.1, 1.2, but this didn't help.

AFAIU the mentioned browsers' refusal to load the page is explained by this:
"Mozilla Restricts All New Firefox Features to HTTPS Only"

But what is the server-side problem?

 

[mrblotto]

Been having this same problem ^ for around a year now, off and on........no idea what the deal is

 

[sandorski]

Haven't had this particular problem, but the latest update to ff 60 has given me a lot of weird performance issues.

 

[Iron Woode]

I just had this issue for the last 15 minutes.

makes no sense at all.

Hey all, we're going to look into this. If it's any consolation I actually don't think it's an issue with the forums. I had the exact same issue with eBay earlier in the week, which makes me think it's a bug with Firefox rather than our site.

I concur. I am betting it's a Firefox issue.

As I said, MS IE had a HTTPS verification problem at the same time. It is not exclusive to Firefox.
