User Reviews
add a wait time(that can be changed) to open tabs
say wait 5 sec before opening each tab to reduce cpu/ram usages

Is Container Opener Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Container Opener requires a few sensitive permissions. Exercise caution before installing.
