Hi maylard, a significant change between Firefox 12 and Firefox 13+ is that SPDY was enabled by default starting in Firefox 13. This probably explains why lines 85-87 only appear for the later version of Firefox:

            Extension: next_protocol_negotiation
                Type: next_protocol_negotiation (0x3374)
                Length: 0

Can someone test disabling SPDY?

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste spdy and pause while the list is filtered

You can double-click to toggle these preferences between true (their default value) and false. I'm not sure what the different versions indicate.

• network.http.spdy.enabled
• network.http.spdy.enabled.v2
• network.http.spdy.enabled.v3

I don't know whether a restart is required for that to take effect.

I just disabled SPDY and restarted Firefox and nothing changed for me.

I can't get into google or facebook & Shaw now has an automated message directing people to use Chrome or Explorer.

Same problem with me I'm with Shaw in Surrey. I have solved the facebook and google problems by switching to Chrome, but I still can't watch videos from live streaming sites such as Twitch.tv...

this problem isn't exclusive to FireFox. a number of other users have said that both FireFox and Chrome can't use streaming sites (ustream, twitch, justinTV)

Thunderbird has the same problem going to Google. How is TLS disabled for it?

hello glenbiagioni, in thunderbird you can reach about:config via Options -> Advanced -> General -> Config Editor. please remember to turn back the security settings though once the problem gets resolved...

I am also in South Surrey, on Shaw and have the same problem. I can access some https sites such as my bank and webmail but can't access either FB or Google on either of my desktops using Firefox. I can access them on Firefox via Wifi on my phone and on my desktops using Internet Explorer.

Hi, I also live in Surrey and have been having this same problem since yesterday (Nov 5th).

I just tried once again to log into my gmail account and it seems to be working again!

Try it for yourselves, hopefully we can all get access via Firefox now to the sites that we have been blocked access too.

Just tried some more sites I couldn't previously access and YEP...

FIREFOX IS WORKING AGAIN!!!

In Surrey .........I can now access Facebook via Firefox! Thank you to whoever fixed the problem!!  :)

I'm east of Maple Ridge and mine is working now too! Yay

Working again in White Rock!

So? Was it Firebox's problem? Shaw's problem? Google's problem? Or all of the above?

hello Happi4gramma, nothing has changed in firefox - a shaw representative on the help section of their homepage stated that they have managed to fix the issue on their part.

Yep... all is good again in Mission, too.

Thank you - whoever you are - for getting this sorted out.

Thanks Philipp :)

Good to know because I've been very pleased since I switched to Firefox!! Thanks for your part in solving the puzzle :)

yep! its fixed (in surrey)

Make sure to reset the security.tls.version.max pref to 1 if you have previously changed this pref to 0 to disable TLS 1.0
