However, now that most people are using SSD this clearly is a problem. To be fair, when this feature was implemented into Firefox, most people were on traditional magnetic disk drives so I’m sure the programmers were not really thinking writing everything to disk would be a issue. That is an excessive amount of writes to your SSD. ![]() (Chrome is writing more up to 20GB a day). The person who discovered this left Firefox open with a few browser windows and tabs open and found Firefox writing about 10GB of data each day. It’s even saving this information when the computer is idle. If you have a large page with a lot of images, etc, it’s writing all of that over and over again to disk. It seems to be just saving everything each time, whether it has changed or not, and it’s saving the actual contents of the page. The problem is that Firefox is saving the state every 15 seconds, but unfortunately it’s not saving it in an efficient manner. When the browser crashes, it simply reloads all the content from the session store file as if nothing had happened. The browser constantly saves the current browser state, such as how many browser windows are open, number of tabs, what URLs you are on, and the contents of each of those pages. If our browser was to crash and we had tens if not hundreds of web pages open, we would be annoyed if we had to open the browser again and try to remember what pages we were on.įirefox (and Chrome) have a Session Restore feature. ![]() When we use our web browser we typically have a few browser windows open with multiple tabs open in each. I’m not going to go into the details of how a magnetic hard drive works in comparison to a SSD, but instead just focus on the fact that your web browser is adding unnecessary wear and tear. I heard this story on my favorite podcast, Security Now (episode 580), and wanted briefly share with you so you know how to help save your SSD. Unfortunately this week, it was discovered that Firefox and Chrome are actually writing excessively to disk, even when you aren’t at your computer. To help extend the life of the drive we should not write excessively to it. The main problem with a SSD is their limited number of writes. ![]() This is great for performance, but SSDs have drawbacks due to the inherit way that they work. Majority of our computers boot from Solid-State-Drives (SSD).
