Hi there!

Please could you write out your question in English? It makes it much easier for us as we can instantly see the issue

One month ago i bought a new laptop - legion y540. My first browser there was firefox, but sometimes, when i'm working there, bluescreen happend. It always come when i'm listening a music or voice messages. In another browsers or game I don't have this trouble. But i realy don't want to use another browser on an ongoing basis. How can i fix it? Only trying to use an older version of firefox?

Please see if a crash report was generated.

The crash report is several pages of data. We need the report numbers to see the whole report.

1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted/Unsubmitted Crash Reports will appear, similar to the one shown below.
2. Copy the 5 most recent Submitted Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

Thank you for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

no, there is no crashes shown

Does it mention a specific DLL or module on the blue screen ?

You can also check Windows Event log for more detail.
