View Full Version : Google Chrome Frame

17 Nov 2011, 6:19 AM
As a company who deals exclusively with American schools, we are stuck supporting older versions of IE... 75% of our traffic is mainly IE8 and IE7. We were upset after trying to upgrade to 3.x and seeing the horrible performance for IE7 and were disappointed after attending this SenchaCon and seeing how Sencha seems to be just moving on from older IE support and even the desktop in general (mobile is the future for this company). Even the new 4.1 is absolutely unusable in anything older than IE9.

We realize that returning to the performance of 2.3 is a pipe-dream, but then we stumbled across this project from Google. We have been watching it over the years and were unable to use it due to most teachers not having administrative rights on their computers. Over the summer, Google released a new version that allows for non-admins to install the plugin... hopefully this will give us the ability to start pushing it to all our users still stuck on older versions of IE and also give us an upgrade path to start using 4.x

We started testing our ExtJS 3 application with Chrome Frame installed on an IE7 box and the results are amazing... we only ran across a few bugs (one big one involving double-clicks), but have managed to get it running with a few overrides. We were wondering if anyone has had any luck using it on a large scale, or has any thoughts on implementing/using it?

I tested it, and I think it's great :)

One problem that I discovered is that Chrome Frame doesn't support the the 'javascript:' protocol. I don't think this would be an issue for most users.

GCF silently updates itself, which may or may not be an issue.

I'm not sure if there's an option to disable it.

This seems incredible!
I didn't know it.
Thank you for the info.

If your entire application runs on IE with GCF, then everything works fine.

However, if your parent window is IE and child window IE with GCF then there is no way you can communicate with parent window from child or vice versa.

Do anyone has a solution for such situation ?

This is all good news. I intend to champion chromeframe to my leadership.

Please do. And if anyone has found any overrides they've had to do I'd be very interested in what you have. I'm hoping to test this in the next few months if I can get corporate approval.

*This was a reply to timmcintyre below - not sure why it bounced above it.

But, while I'm at it, has anyone tried loading up an app from Sencha Touch in Chromeframe? I had considered making a Touch app that would have a profile for phone and one for tablet/desktop and wondered how that'd work out on Chromeframe.

I had heard about this before but never tried it until just now. We also have the issue of 80% of our users are still running IE 8.

I installed GCF on one of my IE 8 browers and its almost as quick as my IE 9 browser in terms of visual loading time. My jaw is still on my desk ;)

Anyway lots more testing to do, however so far everythings looking good . Will keep the forum posted
