Sometimes, the cached data may prevent you from viewing updated content or cause issues when the stored data doesn't match the current content. You can fix browser issues by clearing the cache. This guide will walk you through clearing your cache on popular browsers, with illustrations to make it easier to follow.

Use Ccleaner
Ccleaner - Đây là một công cụ bảo trì máy tính cho phép bạn quét và xoá bộ nhớ và cookies trên trình duyệt. Khởi động công cụ, chọn tab Cleaner và chọn Các tập tin Internet Hiện thời (Temporary internet files) trên trình duyệt bạn sử dụng.
Cảnh báo
- Xoá bộ nhớ trình duyệt KHÔNG GIỐNG với xoá cookies. Hãy tham khảo các bài viết hướng dẫn cách xoá cookies trên trình duyệt để biết thêm thông tin.
Lời khuyên
- Bạn có thể dùng Portable Firefox từ một chiếc USB để lưu lại những dữ liệu (bộ nhớ, cookies, .v.v.) trên thiết bị di động của bạn, mà không phải trên ổ cứng của máy tính.
- Nếu muốn bạn có thể vô hiệu hoá bộ nhớ hoàn toàn trong bảng tuỳ chọn bằng cách chọn 'không lưu lại lịch sử' (do not remember history) hoặc duyệt web ẩn danh. Bộ nhớ được sử dụng để tăng tốc truy cập web bằng cách tải dữ liệu từ bộ nhớ thay cho việc tải lại từ đầu. Tuy nhiên bạn sẽ không nhận thấy sự khác biệt nhiều lắm nếu sử dụng đường truyền internet tốc độ cao.
