Android手机Firefox USB远程调试卡在‘Waiting for browser...’该如何解决？

Hey, glad you caught that you’d missed enabling Remote Debugging via USB in Firefox on your Android device—let’s walk through the full set of steps to get past that frustrating "Waiting for browser..." hangup:

• Double-confirm the Firefox Remote Debugging toggle
  Even though you’ve found this setting now, make sure it’s fully enabled: Open Firefox on your phone → Head to Settings → Scroll down to Advanced → Toggle on Remote Debugging via USB. A quick off-and-back-on toggle can also clear any minor glitches that might be lingering.
• Restart both Firefox apps
  Close Firefox completely on your Android (swipe it away from your recent apps list) and restart it. Do the same for Firefox on your PC—shut all windows and reopen it. This resets any stuck connection states that might be blocking the link.
• Refresh the USB connection
  Unplug the USB cable from both your phone and PC, wait 10 seconds, then plug it back in. When your phone pops up the "USB debugging permission" prompt, be sure to check the "Always allow from this computer" box before tapping "OK"—this prevents repeated permission prompts from interrupting the connection.
• Trigger the connection with a new tab
  On your PC, open Firefox and go to Tools → Web Developer → Remote Debugging. If your device shows up but still says "Waiting for browser," hop over to your phone’s Firefox and open a new tab (navigate to a simple page like about:blank if you don’t have a specific one ready). This often kickstarts the connection between the two browsers.
• Check version compatibility (optional)
  Your PC is running Firefox 72.0.1 and your phone has 68.4.1—these versions are relatively close, but in rare cases minor mismatches can cause connection issues. If none of the above works, consider updating both browsers to their latest stable builds (just remember to back up your bookmarks first if you need to).
