In my reply in this topic I mentioned a chrome extension I use and thought it may be a good subject for us to share the extensions that we rate highly.
I use Mighty Text a lot. I like how I get text messages from my phone onto the computer - and I can type back texts using the normal keyboard on my computer.
On a side note - while not an extension, I love the Android checkbook register app: Volkron Checkbook. I use it all the time, and it backs up to Google Drive for ya too.
As it happens, I just had to turn all my extensions off for testing of some websites. And, when I was done, I turned only 4 of them back on. And probably will keep it that way. Caveat… I’m on Pixelbook (retired, only compute/internet for fun).
