I have Firefox as my default browser (running on Windows 10), but after I have it open for a while I start having performance problems with my laptop because of the amount of memory and CPU that Firefox is using. A few minutes ago, I was having significant response delay while using LinkedIn through Firefox.

As I write this, I still have two LinkedIn windows open plus this support window. Firefox is using 2,340 MB of memory. Firefox CPU usage bounces up to 30-35 % range for several minutes at a time.
