I added the Print Friendly & PDF extension, which will allow me to print only the essential parts of an article. I can remove ads and images that I don't need, saving on ink and paper. I can also change the size of the text and convert the document to a PDF file. For saving images and text, I have added Awesome Screen Shot and Google Drive. I played around with Awesome SS and liked the added tools that allow you to add text, blur images that need to be private & save or share the image. I also created a "project" or collection of images - this is a great feature, but you can only create one project on a free account. My sample screen shot from this site is below - note the blurred face on the left, the added text, and I did crop the image as well.
I added Reader to my Firefox browser. This can change the text size, font, background color and read the text to me. Some of these features are not really necessary for me, but I will try it out a few more times to see if I like it. It is very easy to use.
Chrome Web store has so many extensions and apps that it can be overwhelming. The same can be said about Google Drive add-ons and apps for your mobile phone. I appreciate the suggestions offered by Polly and hope to be able to advise my colleagues and friends on the best ones to add to their browsers for web-based services, online security & creation, collaboration/connection with the digital community.
