Hi, I installed the extension below for Chrome but it seems to not work: https://chrome.google.com/webstore/detail/data-saver/pfmgfdlgomnbgkofeojodiodmgpgmkac?hl=en There is also another option. Some more detailed informations: https://www.keycdn.com/blog/save-data This extension is also available for Firefox: https://addons.mozilla.org/it/firefox/addon/save-data/ Next Sunday I will run a test to check the data consumption with 2 PCs connected to the router. The SIM Card has 50 GB of monthly data. 7.99 Euro/month. Can you recommend other strategies to achieve data savings in the Desktop environment? I will read all the comments with interest without intervening. I have no experience in this subject.
