Is there anyone to take a look at this issue?
It's better to show workaround first.

I just tried this on FF 3.6 on mac with Se 2.3 (i think) and didn't run into the issue.
Using python bindings. I will attempt again tomorrow on windows. Which language bindings
are you using? (Shouldn't matter much for this bug, but I'd like to see if i can reproduce
it).

Now I updated to Selenium2.4, but still blocked here. BTW, I am using Java.

I can confirm, Win7 x64 + FF6.0.2, selenium 2.7

    public void test() throws Exception {
       WebDriver driver = new FirefoxDriver();
       driver.get("http://localhost/a.html");
       driver.findElement(By.id("openPopUp")).click();
       driver.switchTo().window("popupwindow");
       driver.findElement(By.id("backBtn")).click();
       driver.switchTo().defaultContent();
       driver.switchTo().alert().accept();
    }

Firefox driver blocks in click to "backBtn" when alert appears. If one close alert
manually, driver runs ahead, FF console shows the following error message:

Error: [Exception... "Component returned failure code: 0xc1f30001 (NS_ERROR_NOT_INITIALIZED)

Two messages, to be precise, both are the same.

Driver dies with

    at org.openqa.selenium.remote.RemoteWebDriver$RemoteTargetLocator.alert(RemoteWebDriver.java:598)

as the error code in unknown.

I tried on the latest selenium2.21, this issue still blocks script. Does anyone know
any workaround?

Just update: When I disabled native event, the click thread can go ahead and alert can
be accepted.
But for this workaround, can anyone explain more about native event? Since I am not
sure whether the change would impact more situations.

Although there is workaround, but my script is blocked by this issue when tests need
native event to support action such as mouse over.
