Extensity
If you have many tabs open (even if you group your tabs), all of your extensions will run on those tabs which slows down your Chrome web browser and computer. Check out Extensity for quickly enabling and disabling all of your extensions for Google Chrome. It keeps your toolbar clean and you can quickly turn all extensions off (and back on) with a single click.
Teacher Tip Dualless
Having a second monitor is extremely productive for virtual teaching. If you do not have a second monitor, check out the Dualless extension. It splits your browser window two by just 2 clicks. You can choose one of the preset ratios according to your needs. This will be helpful when you are sharing your screen at the next virtual faculty meeting with only your laptop :)
