.aliases: Add chromekill to kill all Chrome tabs to free up memory
Browse files Browse the repository at this point in the history 
Useful when you have a lot of tabs open (which I always do), but you don’t want to close them.

Tabs in Chrome are just processes, so we just filter out the ones we want, and kill them.

Closes #236.

Does it work on both Chrome and Chrome Canary?

Btw, Opera 22+ users can go to Preferences and enable ‘Delay loading of background tabs’ instead. (In Opera 21 it was still a flag: opera://flags/#delay-onload.)

Then whenever you need to free up memory, just close Opera and re-open it. Tabs won’t be loaded until you focus them.

I believe Firefox has similar functionality.

Don’t load tabs until selected: You can keep your Firefox running fast by selecting the “don’t load tabs until selected” option. Firefox will only load the active tab when it starts or restores your previous session. The other open tabs will be loaded as you click on them.

Preferences > Tabs > ✅ Don't load tabs until selected
