First off, heres my device info:

Device name: HP Spectre Convertible Model 15-ch011dx

Processor Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz 1.99 GHz

Installed RAM 16.0 GB (15.8 GB usable)

Device ID F3EDBCEE-137F-4854-B06C-912570DD1DB5

Product ID 00325-81213-26880-AAOEM

System type 64-bit operating system, x64-based processor

Pen and touch Pen and touch support with 10 touch points

Every time i use firefox with even one tab open i end up with extremely high CPU usage-50% or more on average. It causes the exact type of issues that one would expect, and after spending a hours and hours over the last month looking for solutions and implementing anything promising, it hasnt improved. Ive done config edits, countless cache clears, memory snapshots via devtools, and many many other things that have been recommended to me and nothing has helped. running the browser in troubleshoot confirms the problem isnt related to extensions/add-ons or anything like that, because cpu numbers are identical to those seen normally. increasingly i am convinced that this has to be an issue on the mozilla side. reddit confirms i am not alone in struggling with this, not by a long shot.....pls help!

When Firefox launches there will be a spike in CPU usage. Unlike other browser, say MS Edge, the browser components are not already in memory. Post the launch is the CPU usage still high, say 50% of CPU usage or higher?

Further there are anti - virus products which also may lead to high CPU usage as they scan every stream that comes and goes out of the laptop when you are using Firefox. Especially the free ones.

Finally in the Task manager what is the CPU speed that you see when the CPU utilization touches 50% or more? Since you are have i7-8550U which can go upto 4GHz are you seeing a corresponding increase in CPU Speed too? Also if you are running a high resolution, say 2K or 4K with a high refresh rate then also you might face high CPU usage. Have a look at the Firefox's performance settings KB article too.
