I was looking over Chrome and the task manager feature and really wishing something like this was in Firefox (as i have lots of addons [probably too many] and lots of tabs open). I looked for an addon or something but perhaps I have missed something? Anyone know of something like Chrome's task manager but for FF?

There's a couple things you can do to see what kind of overhead you've imposed on Firefox.
The about:addons-memory Extension will give you a nice looking page showing how much memory each of your extensions is using. You can use that information to decide if the overhead imposed is worth the functionality it provides, or if you should look for a more lightweight extension that has similar functionality.
Also, the about:memory page will give you a very technical view of how Firefox is using the memory that's been allocated.
Be careful though, both views give fairly technical information and can be easily misleading if you don't truly understand what you're looking at, how memory allocation in Firefox works, and how your OS manages memory.
As far as I know Firefox doesn't have any built-in way to show the other details that Chrome's Task Manager does, like CPU and Network usage. As @RobK alluded to, Firefox's current architecture may not make providing such statistics easy (or even possible).

5about:addons-memory is currently broken for me(firefox 47). It hasn't been updated since 2014 – Bryce Guinta – 2016-07-10T03:00:48.553
Unfortunately, I can not unload tabs. And the tab unloading add-ons are all bogus. – neverMind9 – 2018-07-14T22:07:58.837

Firefox does not have a task manager. Unfortunately, due to Firefox's architecture it would be difficult to monitor per-tab.
What about Quantum? (I do not like Quantum. But it works similarly to Chrome: seperate processes). – neverMind9 – 2018-06-23T15:04:58.890

There will not be any task manager in Firefox in the foreseeable future. Firefox now feature the Firefox Health Report.

I have still upvoted +1, because -1 stinks like armpit sweat). Still thanks for the answer. Maybe, things will change). – neverMind9 – 2018-06-23T15:07:15.697
I need that to clear the RAM. Tab unloaders do not work. Chrome task manager is highly useful, so Firefox just needs it. – neverMind9 – 2018-06-23T15:04:02.817
