After Firefox 13 update Gmail and Twitter won't load

I have updated to Firefox 13 and now Gmail and Twitter are really slow or won't load at all. I have updated my plugins, I've cleared cache and cookies. What else can I do? Thanks.

Re: After Firefox 13 update Gmail and Twitter won't load

hello, some other users have reported the same issues for gmail & twitter with SPDY enabled (which was introduced in firefox 13).

enter about:config into the location bar & search for the preference named network.http.spdy.enabled and toggle it to false by double-clicking it - this disables the spdy protocol. please see if that works & report back. thank you!

Worked for me and for what its worth, I rolled back to FF12 where everything worked and saw this very setting. Turned it on and it broke GMAIL in FF12 too. What exactly is SPDY supposed to do? EDIT: I completely forgot to say thanks for your assistance as well madperson, so "Thanks for your assistance" Smiley Happy Much appreciated!

Re: After Firefox 13 update Gmail and Twitter won't load

hey, i'm checking back again - another user on the forum has reported, that the problem only occured when the network.http.keep-alive preference in about:config was set to false.

could you have a look if this is also the case on your system? if so please try toggling network.http.keep-alive to "true" (the default value) & network.http.spdy.enabled also back to "true" and see if the sites are still loading normally. because if SPDY is enabled & actually works right this would bring you a performance benefit when loading pages that support the protocol...

if network.http.keep-alive was already set to true, could you look at the other preferences that start with network.http. & see if any of those is not on its default value (=shown in bold) & report it here. this would help further troubleshooting the issue.

OK, lets see if I got this straight... I tried in FF13 the following combinations... network.http.keep-alive to "true" network.http.spdy.enabled also back to "true"... worked network.http.keep-alive to "false" network.http.spdy.enabled also back to "true"... wouldn't even load the link to GMAIL, failed network.http.keep-alive to "false" network.http.spdy.enabled also back to "false"... worked network.http.keep-alive to "true" network.http.spdy.enabled also back to "false"... worked

Does this help?

Can we get some more system information from the people who are having this issue? We are trying to figure out if it is OS/Version specific. All the details you can share will help!
