Before I get to the heart of the matter I need to clarify something. My browser have updated to the new version two days ago. When I open it yesterday it did not restore my session, I checked resently closed windows but it was clean. I looked on the forums and found out that I can use old copies of the session to restore it, unfortunately the "previous.jsonlz4" had already been overwritten, but I found three upgrade.jsonlz4 which may be suitable for restoration, I saved it and others files in another folder. It is a list of files that I have saved: 1.previous.jsonlz4 2.recovery.baklz4 3.recovery.jsonlz4 4. upgrade.jsonlz4-2025.... 5. upgrade.jsonlz4-2025.... 6. upgrade.jsonlz4-2025.... Then the forum said that I need to select one of the appropriate files, rename it to sessionstore.jsonlz4 and replace the old one. The problem is that I can't find sessionstore.jsonlz4. It was said that it appears after closing the browser, but I couldn't find it. Now after this introduction I can move on to my questions. Is it possible that this file is now called differently and this method of recovery can still be implemented? And are there other ways to restore the session? I would be very grateful for help.
