X Browser provides multiple ways to ensure your user data is never lost, maximizing the continuity of your data.

  1. You can go to Browser Settings > User Center > Backup User Data to regularly backup user data to the phone’s public download directory
  2. By default, X Browser automatically backs up user data weekly to the public download directory/com.mmbox.xbrowser directory (you can set the automatic backup cycle)
  3. You can log in to X Browser’s cloud account and backup user data to the cloud.
  4. After logging into the cloud account, you can enable the automatic sync to cloud option. Once user data changes, it will automatically sync to the cloud.

By doing the above, in principle your user data will never be lost. Even if you uninstall the browser and reinstall it, you can easily restore to the previous state from backup files or the cloud.

Troubleshooting Solutions

Page abnormalities, unclickable links, blank pages, layout issues, etc.

The browser kernel’s rendering engine is very complex, especially when dealing with different websites, operating systems, and browser kernel versions, compatibility issues are inevitable. Additionally, X Browser provides many settings options, and different settings may also cause page compatibility issues. For this problem, it is recommended to follow these steps to troubleshoot:

  1. Disable ad blocking: Some blocking rules may cause false positives on certain page elements, causing page abnormalities.
  2. Disable user scripts: If you have installed some user scripts, they usually modify pages to enhance functionality, but may also cause page function abnormalities.
  3. Check if JS is disabled in settings: Most pages need JavaScript to render properly. If you disable JavaScript, many websites will not display correctly.
  4. Clear browser cache: In some cases, browser cache may cause page compatibility issues. Try clearing the browser page cache. Main menu second screen “Clean” option.
  5. If none of the above solves the problem, please go to Browser Settings > Reset to Default Settings. Good luck.

Some web pages won’t open

Please troubleshoot in the following ways:

  • Exit the browser and re-enter to see if the page can open normally
  • Try switching to different network environments, such as testing separately on WiFi and mobile cellular data networks
  • Try accessing with other browsers to confirm it’s not the website itself
  • Disable ad blocking to see if it’s caused by ad blocking false positives

Tip: Some websites that are not properly registered or malicious websites may be blocked by domestic firewalls and cannot be accessed. This is not a browser issue.

Some pages won’t open, but work in UC/QQ browsers

Some URLs, especially illegal websites, are blocked by domestic firewalls when accessed. UC/QQ browsers provide server relay mode (similar to proxy servers) which can prevent firewall blocking to some extent. You can try using X Browser - X5 Kernel Version to achieve similar results.

Web pages can be browsed normally, but cannot login

Most website login functions rely on the browser’s Cookies functionality. Check if the following browser settings have disabled Cookies:

  • Browser Settings > Advanced Settings > Disable Cookies
  • Browser Settings > Security & Privacy > Privacy Mode Does Not Disable Cookies

Browser takes up more space over time

The browser installation package itself is very small. The space it occupies depends on how many web pages you browse. The browser generates cache for each page browsed, such as images, scripts, audio and video resource files. As your browsing history increases, cache size also increases. You can use the following methods to clear cache and reduce space usage:

  • Browser main menu second screen (swipe menu left), select “Clean” option
  • Browser Settings > Advanced Settings > Enable “Auto Clear Page Cache” option

Why does the browser lag?

The author has always focused on performance and memory usage optimization, but even so, different usage habits and scenarios may cause browser lag in some cases. Please try to optimize and check browser performance from the following aspects:

  • Too many blocking rules imported: Too many blocking rules will increase memory usage and cause page loading delays. Blindly adding blocking rules does not significantly improve blocking effectiveness; appropriate blocking rules are best. According to the author’s tests, 100,000 rules will not significantly affect browser performance. Please disable some invalid rules to avoid performance waste.
  • Too many tabs open: Phone memory is limited. Insufficient memory will cause the operating system to frequently swap pages, leading to excessive IO operations and lag. This also depends on phone performance and memory size. According to the author’s tests, within 200 tabs will not significantly affect performance.
  • Performance issues caused by the web page itself: Some web pages consume too much CPU and memory during rendering, causing poor performance and lag. Please try closing related pages.
  • Third-party user scripts installed: Some user scripts consume too much memory and CPU resources, causing browser lag. Please try disabling related scripts.
  • Too much cache also affects browser performance: You can regularly clear browser cache to improve browser performance.

Browser killed by system when switched to background

For simplicity and purity, X Browser does not request high-priority background processes. Given mobile operating system policies, once an application is switched to the background, normal priority processes are easily killed by the operating system to free resources. We can reduce the probability of the browser being killed in the background through the following strategies:

  1. Avoid opening too many tabs or opening memory-intensive pages to reduce memory usage, thereby minimizing the probability of being killed in the background.
  2. Modify the phone system’s power-saving strategy for applications. Taking Xiaomi phones as an example, you can go to “Phone Settings > Battery & Performance > Settings > App Battery Saver” to configure.

What to do when web page back button is hijacked?

Some malicious URLs often hijack the browser’s back button. The behavior is that no matter how you press the back button, it always stays on the current page and cannot go back. At this time, long-press the browser’s back button to pop up the page’s return path list, and select the level you want to return to.

What’s the difference between the domestic version and Google Play version?

The Google Play version and domestic version are almost the same, with only the following minor differences. These differences do not affect your use; choose freely according to your preference.

  1. Google Play is a multi-language version, while the domestic version only has Simplified Chinese and English, so the Google Play installation package is slightly larger.
  2. Google Play version and domestic version have different package names and signatures, which means you can install both the domestic version and Google Play version simultaneously.
  3. Google Play policy does not allow application download links outside the Google Play channel in apps, which means if browser extensions are not listed on Google Play, they cannot be installed, such as casting extensions.

Why do I sometimes have multiple X Browser apps on my phone?

Due to historical reasons, X Browser has different package names in some app markets compared to the official website, such as Xiaomi, Huawei, and Google Play. If you download X Browser from these channels, it will not overwrite the official website’s X Browser program, resulting in two X Browser apps on your phone system. Apart from different package names, the two apps have no other differences. Choose whichever update channel you are accustomed to.
