The updated HTML code brings several changes to improve the appearance and usability of the extension in Firefox. First, the font stack has been modified to include `"Helvetica Neue", Arial, sans-serif`, which closely resembles the default font used in Chrome. The container width has been adjusted to 500px, providing a well-proportioned display across different screen sizes. The header font size has been reduced to 20px for a more compact look. Input fields now have a small margin on the right, creating visual separation from the Clear button. The URL list has a maximum height of 300px with scrolling, preventing it from exceeding the available space. Additionally, button colors have been updated, with the Clear button sporting a red background and the Save button maintaining the primary color. These changes aim to optimize the extension's visual coherence and user experience in Firefox, closely aligning it with the design and font characteristics of the Chrome browser.

The HTML file underwent several modifications to enhance the appearance and functionality of the extension. These changes include restructuring the HTML elements for improved readability and maintaining proper hierarchy. The CSS styles were adjusted to create a cleaner and more visually appealing design, with attention given to element positioning and spacing. External libraries, such as Bootstrap, were removed to ensure compatibility and eliminate potential conflicts. Additionally, the removal of the "notifications" permission addressed the violation notice, aligning the extension with the necessary policies and guidelines. Overall, these enhancements aim to provide users with an enhanced visual experience and seamless functionality within the extension.

Several changes were made to enhance the functionality of the extension and improve the user experience. Starting with the manifest.json file, no modifications were made to it. In popup.html, the structure was updated to include the "Save Current Page" and "Clear All" buttons, with appropriate styling and IDs. The script tag was adjusted to reference the updated popup.js file.

In the popup.js file, the functionality for saving the current page was modified to be triggered by the "Save Current Page" button. An event listener was added to the button, linking it to the saveCurrentPage function. Additionally, the clearAllUrls function was introduced to handle the removal of all saved URLs when the "Clear All" button is clicked. Event listeners for the button clicks were added within the DOMContentLoaded event listener to ensure proper setup when the popup is loaded. These changes allow users to save the current page and clear all saved URLs within the extension's popup. Overall, these modifications significantly enhance the functionality and user-friendliness of the extension.

This update addresses the issue of saved links not immediately appearing in the Firefox extension popup after saving. It introduces a manual refresh mechanism to ensure the newly saved links are immediately visible. The modification includes the addition of a refreshPopup function that reloads the current active tab, triggering the refresh of the extension popup. After saving a link, the refreshPopup function is called to immediately update the popup with the new saved links. The update also includes the use of the browser.tabs.reload method in Firefox to reload the active tab and replaces the deprecated chrome API with the browser API in Firefox. These changes ensure that the extension popup in Firefox will refresh and display the newly saved links without requiring manual closing and reopening of the popup. This improvement provides a smoother and more user-friendly experience when using the Read Later extension in Firefox.

This update addresses the issue of saved links not being immediately displayed after clicking the save button in the extension popup. The modified code ensures that the saved links are retrieved from storage and immediately passed to the displayLinks function to refresh the displayed links. By doing this, the saved link is instantly added to the displayed list, providing immediate visual feedback to the user. This improves the user experience by ensuring that the saved links are visible without requiring a manual refresh or reopening of the popup.

With this modification, the saved links should be fetched from storage and displayed in the extension popup before it is fully loaded, ensuring that the links are immediately visible.

The code changes made to the Read Later extension involved updates to the manifest.json, popup.html, and popup.js files. In the manifest.json file, the "manifest_version" was updated to 3 to align with Manifest V3. The extension's name and description were modified to accurately represent its purpose. The "action" field was adjusted to include the "default_icon" as an object with different sizes specified. Permissions for storage, activeTab, and notifications were added to the "permissions" section. The "icons" field was updated with the appropriate icon sizes.

In the popup.html file, the title was corrected to reflect the extension's name. The styling of the popup was refined to match the desired appearance. An unordered list (ul) with the ID "savedLinks" was added to display the saved links. Additionally, a button element with the ID "saveButton" was introduced to trigger the saveLink() function.

In the popup.js file, the saveLink() function was modified to handle link saving and notifications. The showNotification() function was implemented to create and display notifications using the chrome.notifications.create() method. The displayLinks() function was added to populate the ul element with the saved links. An event listener for the save button was included to invoke the saveLink() function upon clicking the button. Finally, a storage retrieval was incorporated to fetch the saved links from storage and display them when the extension's popup is opened.

These code changes ensure that the Read Later extension adheres to Manifest V3 requirements, allows for saving and displaying links, and provides notifications to the user.
