Disable Chrome session restore popup

Edit the file located at C:\Users\username\AppData\Local\Google\Chrome\User Data\Default

Right click "Preference" file and click edit. ctrl+f to find the following values, and change the value to:

"exit_type": "none",

"exited_cleanly":true,

Save the file, and change the attribute to "read only" so chrome can't change it back.

Chrome has a special flag to disable session restore window. But be aware options in chrome://flags are experimental and you may lose browser data or compromise your security or privacy.

Follow these steps:

• Open Chrome.
• Type chrome://flags/#infinite-session-restore in address bar (Crtl+L).
• Click on the right drop-down menu and change the 'Default' value to 'Disable'. Then restart Chrome to apply that setting.

So what does this do? That option says -- "Reduces the number of tabs being loaded simultaneously during session restore, to improve responsiveness of the foreground tab". After disabling and restating Chrome, it relaunches chrome.exe with --disable-features=InfiniteSessionRestore option.

After @Biswarpriyo s Answer don't work anymore (the flag got removed), it is possible to start Chrome (tried it with 86.0.4240) with the --disable-session-crashed-bubble parameter.

For Linux: Just add it after the command in terminal. For example: chrome --disable-session-crashed-bubble

For Windows: You have to create a shortcut to chrome.exe (usually located in C:\Program Files (x86)\Google\Chrome\Application\ ) and add it to the target like described here

See my answer on how I resolved this for the Chromium on a raspberry pi.
