Firefox before 1.0.7 and Mozilla before Suite 1.7.12 allows remote attackers to execute Javascript with chrome privileges via an about: page such as about:mozilla.

Firefox before 1.0.7 and Mozilla Suite before 1.7.12 allows remote attackers to spawn windows without user interface components such as the address and status bar, which could be used to conduct spoofing or phishing attacks.

The browser user interface in Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 and 7.2 does not properly distinguish between user-generated events and untrusted synthetic events, which makes it easier for remote attackers to perform dangerous actions that normally could only be performed manually by the user.

Firefox before 1.0.5, Thunderbird before 1.0.5, Mozilla before 1.7.9, Netscape 8.0.2, and K-Meleon 0.9 runs XBL scripts even when Javascript has been disabled, which makes it easier for remote attackers to bypass such protection.

The InstallTrigger.install method in Firefox before 1.0.5 and Mozilla before 1.7.9 allows remote attackers to execute a callback function in the context of another domain by forcing a page navigation after the install method has been called, which causes the callback to be run in the context of the new page and results in a same origin violation.

Firefox before 1.0.5 allows remote attackers to steal sensitive information by opening a malicious link in the Firefox sidebar using the _search target, then injecting script into other pages via a data: URL.

Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 and 7.2 allows remote attackers to cause a denial of service (access violation and crash), and possibly execute arbitrary code, by calling InstallVersion.compareTo with an object instead of a string.

Firefox before 1.0.5 and Mozilla before 1.7.9 allows a child frame to call top.focus and other methods in a parent frame, even when the parent is in a different domain, which violates the same origin policy and allows remote attackers to steal sensitive information such as cookies and passwords from web sites whose child frames do not verify that they are in the same domain as their parents.

Firefox before 1.0.5 allows remote attackers to steal information and possibly execute arbitrary code by using standalone applications such as Flash and QuickTime to open a javascript: URL, which is run in the context of the previous page, and may lead to code execution if the standalone application loads a privileged chrome: URL.

Firefox before 1.0.5 and Mozilla before 1.7.9 does not clearly associate a Javascript dialog box with the web page that generated it, which allows remote attackers to spoof a dialog box from a trusted site and facilitates phishing attacks, aka the "Dialog Origin Spoofing Vulnerability."

Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 does not properly verify the associated types of DOM node names within the context of their namespaces, which allows remote attackers to modify certain tag properties, possibly leading to execution of arbitrary script or code, as demonstrated using an XHTML document with IMG tags with custom properties ("XHTML node spoofing").

Firefox before 1.0.5 and Mozilla before 1.7.9 does not properly clone base objects, which allows remote attackers to execute arbitrary code by navigating the prototype chain to reach a privileged object.

Firefox before 1.0 allows the user to store a (1) javascript: or (2) data: URLs as a Livefeed bookmark, then executes it in the security context of the currently loaded page when the user later accesses the bookmark, which could allow remote attackers to execute arbitrary code.

Firefox before 1.0.4 and Mozilla Suite before 1.7.8 does not properly implement certain security checks for script injection, which allows remote attackers to execute script via "Wrapped" javascript: URLs, as demonstrated using (1) a javascript: URL in a view-source: URL, (2) a javascript: URL in a jar: URL, or (3) "a nested variant."

Firefox before 1.0.4 and Mozilla Suite before 1.7.8 do not properly limit privileges of Javascript eval and Script objects in the calling context, which allows remote attackers to conduct unauthorized activities via "non-DOM property overrides," a variant of CVE-2005-1160.

Firefox 1.0.3 allows remote attackers to execute arbitrary Javascript in other domains by using an IFRAME and causing the browser to navigate to a previous javascript: URL, which can lead to arbitrary code execution when combined with CVE-2005-1477.

Firefox before 1.0 and Mozilla before 1.7.5 allow remote attackers to load local files via links "with a custom getter and toString method" that are middle-clicked by the user to be opened in a new tab.

Firefox before 1.0 and Mozilla before 1.7.5 display the secure site lock icon when a view-source: URL references a secure SSL site while an insecure page is being loaded, which could facilitate phishing attacks.

Firefox before 1.0 and Mozilla before 1.7.5 allow remote attackers to obtain sensitive data from the clipboard via Javascript that generates a middle-click event on systems for which a middle-click performs a paste operation.

Firefox before 1.0 and Mozilla before 1.7.5, when configured to use a proxy, respond to 407 proxy auth requests from arbitrary servers, which allows remote attackers to steal NTLM or SPNEGO credentials.
