Browser Bloat & Service Workers - 4x3 draft 6

  1. 1. Browser Bloat & Service Workers or why is my system getting so slow? CUCUG 8pm 1/16/20 Mark S. Zinzow Slideshare.net/ms
  2. 2. The Problem Browser bloat can lead to system crashes or freezing. “In computer science, thrashing occurs when a computer's virtual memory resources are overused, leading to a constant state of paging and page faults, inhibiting most application-level processing.[1] This causes the performance of the computer to degrade or collapse. The situation can continue indefinitely until either the user closes some running applications or the active processes free up additional virtual memory resources.” https://en.wikipedia.org/wiki/Thrashing_(computer_science)
  3. 3. Solutions While there is no easy fix to quickly reduce browser bloat, there are many steps that can help. ♦ Say No to notification requests when ever possible. This is how service workers get to stay active too much ♦ Reduce Subframes with ad blockers or privacy protection tools. ♦ Block JavaScript when practical. ♦ Use Memory Monitoring tools to find the hogs. ♦ Manage Extensions to pick small and necessary ones; disable them when not needed. ♦ Exclude Extensions from Sync. ♦ Restart Your Browser Often.
  4. 4. Terms Memory footprint refers to the amount of main memory that a program uses or references while running. https://en.wikipedia.org/wiki/Memory_footprint A service worker is a JavaScript file that operates as a type of web worker. They work separately from the main browser thread to handle push notifications, synchronize data in the background, cache or retrieve resource requests, intercept network requests and receive centralized updates.[27] Service workers are used in an attempt to give progressive web apps the ability to provide the high performance and rich experience of native mobile apps, with the low storage space, real-time updates and improved search engine visibility of traditional web apps. https://en.wikipedia.org/wiki/Progressive_web_application#Service_ workers Subframe: an iframe page element separated from its parent page into a unique process by site isolation.
  5. 5. Is This Browser Hijacking? Or just the last straw? Browser hijacking is a form of unwanted software that modifies a web browser's settings without a user's permission, to inject unwanted advertising into the user's browser. https://en.wikipedia.org/wiki/Browser_hijacking

  7. 7. Firefox Site Permissions... Are a bit more work to find than Chrome's site settings. Click the padlock, then the >, then More Information, and then finally the Permissions tab. While blocking JavaScript is not on the menu, at least you can find the notifications setting for the current tab.
