The API this extension is built upon is being deprecated starting Chrome 64.

A rewrite is needed to use nextHopProtocol of Resource Timing Level 2 API.

SPDY reporting as disabled with Chrome 36.0.1985.125 on OS X

I tried even with google.com and other sites that I do know to be working (Firefox with similar extension is reporting them as using SPDY), but now on Chrome is always reporting SPDY as disabled.

Would it be possible to replace the raster icons with scalable vector svgs? Right now the pngs look crummy on computers with large font size ('dpi').

The star and stack icons look good, but the spdy (and envelope) icons are pixelated.

The interesting details in the hover message (SPDY and QUIC versions) are hard to read when there's a long URL in the hover message. Does the URL need to be in the hover message at all? There's the location bar for that.

Thanks for the awesome extension.

chrome.loadtimes() APi is deprecated(See #38). I didn't know it is hosted on GitHub before, so made a new extension to fix this.

I'm glad to submit a PR if you have the fix plan :)

Don't show icon at all if it is not SPDY-enabled.

Now it is showing grey lightning.

I believe this option is obsolete now that the extension always has to be in the Toolbar. Correct me if I'm wrong, but it doesn't do anything that I notice on my machine.

I happened to notice that you missed a leading space in the hover text when spdy is not enabled. Should be just about the easiest fix ever!

Hello! Sorry if this is off-topic. I am looking to do a "HTTPS indicator" for the Chrome's app mode. For example to login on Gmail. I know that it uses HSTS already; it was an example only. Could you give me tips regarding the API? I still will go to study from your source code.

On Chrome 50.0.2633.3 dev-m (64-bit) the icon never changes (stays as icon.png) however the tooltip does change

Recently I had my HTTP/2 and SPDY indicator disappear from my toolbar. Upon checking my extensions manager, I see the notice "This extension violates the Chrome Web Store policy."

Please investigate and update if possible.

Hi,

as of today with the latest chrome dev-m release the indicator is only shown when pages are not H2 enabled ("blank" icon). On HTTP/2 sites, regardless of protocol, the icon went away. Tested on H2, H2-14, SPDY/3.1 and QUIC enabled sites.

Some time ago, Chrome introduced a new mechanism of tab preloading - usually used for instant search.

Such tabs are loaded/rendered off-screen, and then the current tab is swapped for the new one.

This results in a race condition: if the page loading is very fast, the message to set the icon may arrive before the tab is visible - and that makes the indicator not show up, even after the tab is swapped in. A reload fixes it.

The proper way to correct this is to have a listener to chrome.tabs.onReplaced event and run the content script again for the swapped-in tab.

My website supports HTTP/2, however chrome-spdy-indicator can't indicate it

Hi. Have the colours for the lightning icon changed? As I remember, the algorithm was:

1. If transport layer is QUIC, then set icon to red
2. Otherwise if application layer is HTTP/2, then set icon to blue
3. Otherwise if application layer is SPDY, then set icon to green

But lately I've seen green for 'http/2 + QUIC' which doesn't agree. What's going on?

Due to a recent user interface change in Google Chrome, this browser extension now manifests as a persistent button in the tool bar. See: #25

Previously, when a page was loading and the HTTP connection wasn't yet established, this extension's icon was hidden. However, now it displays the greyed out default icon, which looks somewhat purposeless and mystifying:

Once the HTTP connection is established, it shows the relevant icon:

What would be a good icon to display while the HTTP connection is being established?

In chromium 47 the indicator is a regular extension button and it no longer sits in the address bar.
Could it be moved back to the address bar?
