Did this issue start in 57.0.2 whereas 57.0 and 57.0.1 were fine, or is 57.0.2 the first 57 version you use after updating from 56.0.2 or older? If the latter is true, I might be wrong but from the head, your laptop may contain an Intel Broadwell CPU that may need its microcode to be updated. See the [[Crash on Broadwell-U with old microcode]] article for more info on how to check and update it. I understand this is not about Firefox itself crashing but Windows instead, so you probably won’t see crash reports generated by Firefox, if you could start it in the first place. Nevertheless you could have a look to see if any crash reports have been generated, as follows: #On the keyboard, press [Windows] [[Image:Windows key]] + [R]. This should bring up a Run window that contains a text field. #In that text field, type '''%APPDATA%''' and press Enter. An explorer window should open. #From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''. #Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window. #Open the most recent 5 files with a text editor and copy the IDs. #Paste each ID with '''bp-''' into the reply window on the forums. You can find more information and troubleshooting steps in the [[Firefox crashes]] article. If there are no ''submitted'' reports generated by Firefox, please provide the error code generated for the Windows crash (see the Windows system and application logs if you don’t see them due to a possible requirement to restart your PC), as well as your exact PC make and model and any security software involved. Other reasons for Firefox crashing on startup (usually limited to Firefox, not causing Windows to crash) are in security software such as G Data security software (see [[Firefox startup crash with G DATA security software|here]]) and Comodo (see [[Firefox crashes on startup for users of Comodo security products after July 2017 Windows 10 update|here]]).
