Hello, I'm sorry to hear that you're experiencing weak internet connection issues with Firefox on Windows 11. As a Firefox support volunteer, I'm here to assist you in resolving this problem. To address your weak connection issue, we can try the following troubleshooting steps: Check your network connection: Ensure that your Wi-Fi or Ethernet connection is stable and properly connected. You can try restarting your modem/router and reconnecting to see if it improves the connection. Clear Firefox cache: Sometimes, a build-up of cached data can affect browsing performance. To clear the cache, go to the menu (three horizontal lines) in the top-right corner of Firefox, select Options, then Privacy & Security. Under the Cookies and Site Data section, click on "Clear Data" and select the appropriate options. Finally, click on "Clear" to remove the cache. Disable add-ons and extensions: Add-ons and extensions can sometimes interfere with the browser's performance. Try disabling any installed add-ons or extensions to see if it improves the connection speed. You can do this by going to the menu, selecting Add-ons, and then disabling or removing any unnecessary extensions. Reset network settings: Resetting your network settings can help resolve connectivity issues. Open the Windows Settings, go to Network & Internet, and select the "Network reset" option. Follow the instructions to reset your network settings. Update Firefox: Make sure you are using the latest version of Firefox. Go to the menu, select Help, and click on "About Firefox." If there is an update available, Firefox will automatically download and install it. If these steps don't resolve the issue, please provide more specific details about your network setup, any error messages you're encountering, or any other relevant information. This will help us further investigate and provide you with appropriate solutions. Please let me know if you have any questions or need further assistance.
