Does running multiple extensions in Chrome slow browser?
Yes, definitely, but different extensions have different impacts, and while some only affect Chrome when you use them (e.g. when you right click and choose them), others take a toll on Chrome all the time. You can use Chrome's task manager (Shift Esc) to get an idea of the impact of the extensions at any particular time.
Thanks. I have noted the concept with care. Please tell , Do chrome extensions which are installed but 'not enabled' ( Enabled box unchecked in list of Extensions in Chrome Tools - Extensions menu ) equally slow down Chrome? or only enabled extensions slow Chrome?
No, a disabled extension does not run, and therefore does not use computer resources in the same way. It may still have some residual effect because they mentioned in various configuration settings and they add to the file count, but that effect will be negligible.
Chrome’s task manager
you can see which extensions are heavy also extensions that inject code into pages when you load web pages may not appear.
Keeping Chrome Extensions Simple
Thanks. I have noted both the links with care. Are 'browser processes' and 'extensions' one and same?
browser process is google chrome engine
engine are the addons from other sources
if you go to Google Settings-Advanced Settings there is System under which you have the option: Continue running background apps when Google Chrome is closed.
Some applications like cloud based stay alive at the background and that keeps the tasks alive in the task manager.
