IE9 Compat Inspector

I've come across DOZENS of pages that will not work in IE9, most from very main-stream sites. Gmail video for one... it gives an error message about the constant and runtime values not matching (IE6 vs IE9). Time Magazine had an interactive survey, and none of the radio-buttons or voting buttons worked. Similarly, on several real estate sites, the "slide shows" utterly fail to work. I've actually had to download and install Chrome as my "fall back" browser just to view and work with these pages. It's very frustrating, as I've rarely if ever had to do this before. In most cases, even "compatibility mode" (when it's an option) won't fix things. It seems each week that goes by, I find one or two more pages that just don't work in IE9.

This is a report as a frustrated user, rather than from wearing my developer hat.

@Tony that's because Steve is a hysterical wuss. Instead of trying to resolve issues he complains left and right.

@Steve

I'm not sure I understand why you can't test your "old code" in standards mode. Even if the page doesn't run in standards mode by default, you can still use the developer toolbar to temporarily switch over so you can test. Just press F12 to open the tools, click on "Document Mode" in the menu bar, then select "Internet Explorer 9 standards".

Oh for the love of god... Awesome tool, but it won't even run unless your site is running in full standards mode.

Thus if you are trying to fix a site with "old code" to get away from broken old IE code, you can't.

Total waste of a download.

Grrrrrrrr!

Just an FYI:

So I loaded the Compat tool in Fiddler using FiddlerScript... and thus I have the tool available in IE9 and it works very well.

However Even with Fiddler Disabled in Firefox, it attempts to inject the script into the stream (or whatever it does) and causes errors in Firefox.

Other than that, thanks for the cool tool. I can't wait to find all kinds of errors and warnings to fix ;-)

Oh, and btw... OMFG this FONT RENDERING / ANTI-Aliasing sucks beyond belief! I can't believe there isn't a patch for this yet.

What I meant was: Could you please release statistics on how many of the major sites rely on which compatibility modes and therefore which compatibility modes would be the likeliest candidates for being dropped in future versions?

Very nice!

BTW: Could you maybe release the numbers on what number of the top sites rely on which compatibility modes?

Very cool tool. IE needed this about 8 years ago. Though i'll take it now even if it is too late for IE to compete.

Hi,

I tried to make a bookmarklet that script but in DevTools' said:SCRIPT5007: Unable to get value of the property 'substring': object is null or undefined

What I'm doing wrong? I can't use as bookmarklet?
