Which browsers support Window's Low Integrity level?

Normally i like running ie, but it's rendering speed at high-dpi is poor.

More recently i've switched to Chrome, but it does not support high-dpi displays. i'm interested in trying other browsers, but they must support protected mode.

Are there any other browsers, besides IE and Chrome, that support Mandatory Integrity Levels (i.e. protected mode)?

Browsers that i know about:

Browser            Protected Mode   High-dpi Aware
==============     ===============  ==============
Internet Explorer      Yes              Yes
Chrome                 Yes               No
Firefox                 No               No
Opera                   No               No
Safari                  No*              No*

(* not personally tested, reported by others)

Are there any others?

And just as an fyi, the clear, unambiguous, non-argumentative, non-subjective, question is:

Are there any browsers, aside from Internet Explorer, available for Windows, that run at the Windows Low Mandatory integrity level, and support high-dpi (i.e. non-96 dpi) displays?

You may want to try Internet Explorer 9 Beta.

i am. And while the fixed the high-dpi rendering speed (as well a javascript performance), they made a lot of negative changes that will keep me from using it. – Ian Boyd – 2010-11-25T05:25:49.337

1@Ian: Such as..? I'm just curious what they did wrong. – Sasha Chedygov – 2010-12-07T05:32:11.567

1Indeed. By "negative changes", do you mean things that actually make it act more standard (which could confuse sites that sniff for IE...), or? – SamB – 2010-12-08T16:40:45.097

@musicfreak: i was referring to user interface changes. Plus there are many usability features in Chrome that i've discovered i cannot live without. But the biggest issue is that IE lacks an extension API; which is preventing a port of AdBlock. i've used Chrome so long that when i tried IE9 beta i was jarred by the sheer volume of ads on the internet - and obnoxious ones, too. – Ian Boyd – 2010-12-15T15:02:31.627

@Ian Boyd: Fair enough. I haven't used IE9 yet so I was curious. – Sasha Chedygov – 2010-12-15T22:21:20.007

icacls %UserProfile%\appdata\local\opera\opera /setintegritylevel (OI)(CI)L

icacls %AppData%\opera\opera /setintegritylevel (OI)(CI)L

Apart from these you need to remove NoWriteUp (-nx) from these folder. you can use chml.exe for that

I use chml <folder> -i:l -nx when using chml.exe you have to use one of -nx -nw or -nr else it is taken as -nw. So I use -nx to prevent -nw and -nr.

Works well for me but a couple of seconds delay in starting Opera and an additional application launch security warning.

Purely in the interest of providing a POTENTIAL alternative, you can screw around with Opera to make it do both of those things.

Low Integrity Level: I found a site that experiments with this

icacls %programfiles%\opera\opera.exe /setintegritylevel L

This sets the executible to run at LI, but it wont run.

icacls %UserProfile%\appdata\local\opera\opera /setintegritylevel (OI)(CI)L

It runs, but cannot retain preferences

icacls %AppData%\opera\opera /setintegritylevel (OI)(CI)L

And now it retains most preferences.

I found that here

As for high-DPI display, if you enter opera:config there is a "force DPI" setting, you can set it higher than 96 and see how things look. Perhaps worth a try!

This mirrors a question i asked about how to run FireFox in protected mode (http://superuser.com/questions/30668/how-to-run-firefox-in-protected-mode-i-e-at-low-integrity-level). It has the same issues as Opera. Unfortunately, to be truly usable the browser needs to be designed from the ground up with low rights users in mind.
