How to Optimize Google Chrome Browser (Updated 2023)

There is a way how to optimize Google Chrome web browser. Also works on both Chrome versions that I tested with tweaked flags (versions 94 and 100).

Privacy and Security > Site settings:

• Cookies and other site data - Block third-party cookies
• Location - Don't allow sites to see your location
• Camera - Don't allow sites to use your camera (if you have a webcam, just leave it default)
• Microphone - Don't allow sites to use your microphone (if you have a microphone, just leave it default)
• Notifications - Don't allow sites to send notifications
• Motion sensors - Don't allow sites to use motion sensors
• Unsandboxed plugin access - Do not allow any site to use a plugin to access your computer (removed since version 88)

System:

• Continue running background apps when Google Chrome is closed - DISABLED
• Use hardware acceleration when available - ENABLED (If you get issues, disable this)

Flags:

• Smooth Scrolling - DISABLED (Leave it default if you keep smooth scrolling enabled)
• Experimental QUIC protocol - ENABLED
• Parallel downloading - ENABLED
• Tab Hover Card Images - DISABLED
• Destroy Profile on browser close - ENABLED
• Turn off caching of streaming media to disk + while on battery power. - ENABLED
• Enable LiteVideos + Force LiteVideos decision - ENABLED (Alternate flag to turn off caching)

Launch Parameters:

• Paste these launch parameters after the quotations: --process-per-site --disable-hang-monitor --disable-background-timer-throttling --disable-backgrounding-occluded-windows

Note: If you are using a version of chrome prior to 2022 to disable tab throttling, You can just use this launch parameter here: --disable-features=CalculateNativeWinOcclusion,IntensiveWakeUpThrottling

If you want looking for older version with tweaked flags and launch parameters, links above here.

• List of tweaks for versions 88 and below
• List of tweaks for versions 72 and below
• List of tweaks for versions 46 and below

Extensions:

• H264ify / Enhanced-H264ify - Makes YouTube stream H.264 videos instead of VP8/VP9 videos. This could result in a better playback if on low-end PCs. Also, be sure to disable 60FPS in the options if your system is very low-end
• uBlock Orgin - A more CPU-friendly version of Adblock
• FasterWeb - It will speed up the entire browsing by using just-in-time preloading.

Remove Google Docs online or any extensions similar if you do not need it...

Tips:

• Limit your extensions
• Turn off other processes in the background
• Update Chrome to the latest stable builds (sometimes beta builds can help too, but they are not fully tested)
• If you are using a 64-bit system, be sure to use the 64-bit Chrome, also do the same on a 32-bit system
• Clear your browsing data often. You do not need extensions to clear it for you. CTRL + H then clear everything.
• Sometimes, reinstalling Chrome is a good way to achieve max performance

Top List of Worst Chrome Versions EVER!!!

As you might know, Chrome's worst version has some bugs in it, because there are some lists --

Chrome 59: The website Wikia does not support Adblock and Adblock Plus, when you search on Wikia with arrows and it just doesn't respond!

Chrome 55: Omnibox is clicked and you see there is a blue border (fixed on v56+)

Chrome 51: For some reason on Windows, because Adobe Flash lacks anti-aliasing (See crbug.com/615375)

Chrome 47: Some context menus on HTML5 are missing (returned in v48)

Chrome 37: It actually has some performance issues with VirtualBox and scaling was terrible...

Chrome 32/33: The scrollbar has no up and down arrows.

That's all for this!
