I have summarized 24 differences in IE8. In fact, there are more than 24. Counting sub-items, there are probably more than 40.
1. Smart address bar matches content
The smart address bar allows users to not only find the desired website, but also match the titles in history and favorites with the content entered by the user in the address bar without duplication.
2. Tab grouping association
Tab grouping allows users to confirm which tab has relevant content. When clicking a link in one tab leads to another, the new tab will appear next to it, and both tabs will be marked with a color.
3. Right click to click on the "New Tab" page
The "New Tab" page in IE8 has been redesigned to allow users to right-click on the page to perform common tasks.
4. Reopen the last page you visited
In the event that the browser is accidentally closed or the browser crashes, IE8 allows users to reopen recently viewed pages.
5. Internal search "Search within page"
a) Improved the way people search for text on the web.
b) Search within the page: Press Ctrl+F or select in the edit menu or instant search dialog box to turn on the search function within the page. The toolbar appears below the user's tabs so it doesn't obstruct any text on the page.
c) Number of results: The enhanced search function within the page will display the number of times the search term appears on the page.
d) Result Highlighting: Enhanced in-page search capabilities allow users to find search terms at a glance because all occurrences of search text are highlighted.
6. Slipstream installation
Customization of IE8 execution and part of the Windows Vista operating system image can be achieved, and separate installation is no longer required. When used in this way, IE8 becomes part of Windows Vista, thus improving desktop consistency and manageability.
7. Equipped with IE management tool kit
Favorites customization and the ability to import accelerators
8. Added more than 140 settings:
IE8 controls and configures browser features including accelerators and web alerts, supports regional objects such as InPrivate, Compatibility View, and SmartScreen, and adds more than 140 new settings, bringing the total to nearly 1,500.
9. Added and modified seven subsystems
In addition to improvements in standards support, IE8 also includes platform features for developers. There are also performance improvements in many subsystems, such as the HTML parser, cascading style sheet (CSS) rule processing, tag tree construction, Jscript parser, clear object time and memory management. Features for developers include:
a) CSS 2.1: IE8 fully supports the CSS 2.1 specification, so web developers and designers can instantly develop web pages and render them accurately on multiple browsers.
b) Document Object Model (DOM) and HTML 4.01 improvements: IE8 has fixed many cross-browser inconsistencies; for example, operations such as getting/setting/deleting attributes can interoperate with other browsers, while asynchronous Java Script and XML ( AJAX)
c) Emerging standards: IE8 incorporates technological advances that will become industry standards in the future, such as W3C's HTML 5 Draft DOM Storage standard, Web Applications Working Group's Selectors API and ECMAScript 3.1 syntax.
d) New browsing features for AJAX applications: Developers can now update the browser front and back browsing stack and address bar in their AJAX applications so that these browser features can be used in AJAX applications.
e) Acid2: IE8 can accurately render the Acid2 browser test.
f) Compatibility: IE8 comes with more standards-compliant typography support, allowing developers to develop websites using a single standard for multiple browsers. To give developers the choice of when to migrate to a layout engine that conforms to the new standards, IE8 web developers can adopt the IE7 layout engine by simply inserting a simple meta tag in their code or adding a simple http header on the server.
g) Developer visual tools: Allow developers to quickly debug HTML, CSS and Jscript in a visual environment. These tools have been built directly into IE8 and include extended functionality, including a menu option for selecting which application to use when viewing source code. Based on the analysis provided by this tool to the DOM.
10. Break through page limits
IE8 breaks through page restrictions, and the features involved include:
a) Accelerator: Accelerator eliminates most of the mouse clicks previously required to access content and services,
b) Web alerts: With web alerts, people usually don’t have to leave the web page they are browsing to see the information they most want to see, and developers can mark a certain part of the web page as a web alert so that users can monitor what they most want to see. Frequently browsed information. In the Favorites column, users can find web alerts with updated content displayed in bold, with visual content and links to the source web page.
c) Instant search box: The enhanced instant search in IE8 makes it easier for users to find content of interest and improves the relevance of search results. As users enter search terms, they will see search suggestions from their chosen search provider in real time, including images and rich text. To facilitate real-time switching between sites and search provider search suggestions, a menu is also available at the bottom of the search box. In addition, the instant search box can also display search results from the user's favorites and browsing history.
11. 3 layers of security protection
a) InPrivate: InPrivate provides protection by avoiding retention of user’s data and private information on the PC. This is a protection against third parties who may track users' online activities. Users can use both functions (InPrivate browsing and InPrivate filtering) independently.
b) InPrivate browsing: When enabled, InPrivate browsing ensures that browsing history, temporary Internet files and cookies are not recorded on the PC. In InPrivate mode, toolbars and extensions are automatically disabled, and browsing history is automatically deleted when the browser is closed.
c) InPrivate filtering: InPrivate filtering helps protect user privacy by allowing users to block third-party content designed to track and collect user network activities. Users are alerted and have choices and control over what third-party content is allowed or blocked.
12. View Compatibility View
IE8 provides an easy way to fix display issues such as misaligned menus, images, and text because the compatibility review button can be displayed as the page was originally designed. Some websites are designed for older browsers and therefore will not display properly in IE8. By default, IE8 renders content in the most standards-compliant way.
13. Compatibility Checklist
Users using IE8 can choose to receive a list of major sites that perform best in compatibility checks. When browsing a website on this list, IE8 will automatically display the website in compatibility view mode without requiring the user to press the compatibility view button.
14. Crash recovery
In IE8, if a tab crashes, it will automatically recover and reload, and any information the user has entered on the page (such as composing an email or filling out a form) may be restored.
15. Delete browsing history
IE8 has enhanced the function of deleting browsing history, supporting the deletion of certain cookies, history records and other data, while retaining cookies, history records and other data for favorite sites.
16. SmartScreen filter
The SmartScreen filter is derived from Microsoft's phishing attack filter and helps protect against phishing threats and blocks websites trying to download malware. SmartScreen filter provides user interface and alarm information.
17. Clickjacking Prevention
This new feature of IE8 allows website content owners to add a label to the header of the page to help prevent clickjacking - a type of cross-site request fraud. Clickjacking includes a variety of techniques used to trick users into unintentionally clicking on hidden or non-obvious web elements, often causing unexpected activity. IE8 detects tagged sites and displays an error screen to indicate that the content host has chosen not to allow the content to be displayed, while giving the user the option to open in a new window.
18. Cross-site scripting (XSS) filter
IE8 helps protect users and systems from information leakage, stolen cookies, account/identity theft, or impersonation of the user without their permission. XSS attacks are an attack method that exploits web servers and web applications: IE8 has an XSS filter that can dynamically detect Type 1 XSS (reflection) attacks.
19. Data Execution Prevention (DEP)
DEP is enabled by default in IE8 in Windows Vista Service Pack 1 and can help prevent viruses and other security threats from harming your computer by preventing certain types of code from being written to the executable memory area.
20. Cross-file messaging (XDM)
XDM provides a highly secure method for disparate documents to communicate with mutual consent. XDM provides standards-based bidirectional cross-file communication while also providing StaticHtml methods and native JavaScript Object Notation support to protect data without sacrificing performance.
21. Cross-domain request (XDR)
Cross-domain communication is an indispensable part of AJAX development and mesh applications. IE8 supports the XDomainRequest object, which can request public resources from a server in another domain. XDR checks Access-Control-Allow-Origin for specific URLs and wildcards, and cross-domain data is available when only server signals clearly indicate that data is being shared across domains.
22. Domain name highlighting
IE8 highlights the domain name of the URL string in the address bar in bold font to identify which website is being visited and identify phishing websites and other deceptive websites. The domain name is displayed in black font, distinguished from other gray characters in the URL.
23. Website ActiveX:
ActiveX for websites reduces the attack surface by providing an "implicit" SiteLock (a tool that restricts access to specific domains) so that, by default, the control only kicks in after installation. This allows the user/administrator to manage where ActiveX can run.
24. Single-user ActiveX:
Single-user ActiveX enables developers to write their ActiveX controls so that when a user installs it, it is installed only for that user, not all users on the system, and provides other users with protection against malware or bad writes Controlled protection.
