So for the last couple of years it has seemed like Chrome has been going downhill to me. A lot of my friends and fellow web developer buddies have been noticing the same thing. It has mountains upon mountains of memory leaks. Even some that Google has admitted they can't fix. It got to the point where if I watched 3 YouTube videos in a row, the third one would start stuttering and slow down my whole computer until I closed and re-opened it. It is also a resource hog. At any time if you are on Windows, open the Task Manager and look at the Processes tab. I bet you have way more processes of Chrome running than you have tabs open. This supports the "re-open a closed tab" feature, but I think it could be done a lot better.
I have actually switched to Firefox Quantum. At first I was just part-timing with it to see if I could get used to the change. That lasted about 2 weeks and now it is my main browser. Its developer tools are at least on part with Chrome's. It feels a heartbeat faster and does seem to be beating Chrome in speed In pretty much every speed test I can find. Its built-in ad blocking tool works at least as good as AdBlock but it isn't detected on a lot of websites that try to hit you with a paywall if you use AdBlock (although regular AdBlock is available if you want to use that instead).
I was able to import everything from Chrome so I didn't lose my bookmarks, history or anything else. All-in-all I have been very happy about the switch. FFQ's footprint on my machine feels much smaller and it seems that it doesn't slow my machine down the way Chrome was.
If Chrome is working great for you, keep using it. But if you keep running into issues and feel like it could be doing better, give Firefox Quantum a try. If you don't like it, you can always just uninstall it and go back.
