Firefox has improved its multi-process architecture in order to isolate more content while keeping memory use low:
Firefox 54 launched with a more advanced multi-process architecture than the one we saw implemented in Firefox 48 last year. The improved architecture raises the number of processes enabled by default from two to five, which Mozilla argues is a "just right" compromise between low memory usage on one side and performance and security on the other.
[...] Switching to a simpler extension model allows Firefox to enable multiple processes and also isolate them in sandboxes. Mozilla previously enabled only two processes, one for the UI and one for content, last year, in Firefox 48. This ensured that the browser wouldn't hang as much due to web pages affecting the performance of the browser interface. It also brought partial sandboxing by keeping the content isolated from the browser (as much as possible).
Mozilla is now taking it to the next level by implementing one process for the browser interface and four for content. Why four? The organization believes that this is the "just right" amount of processes to have for the majority of users, and also in terms of optimizing memory usage.
[...] Mozilla ran its own memory usage benchmarks, which showed significant memory usage reduction compared to Chrome:
- Windows 10 — Chrome used 1.77X memory as Firefox (64-bit), and 2.44X as Firefox (32-bit)
- macOS — Chrome used 1.36X memory as Firefox (64-bit)
- Linux — Chrome used 1.42X memory as Firefox (64-bit)

Laptop memory is about $40 for 8 GB. This is higher than it was years ago, probably due to Elpida going bankrupt and supply reduction in response to anemic PC demand. Prices are similar for DDR3 and DDR4.

When you buy a laptop, the extended specs should tell you how many DRAM slots there are and how many are occupied. One 8 GB stick and one empty slot is common, which would be an easy upgrade to 16 GB. Timings and clocks don't usually have to match although that could spell trouble.
In 2017, it's rare to see a laptop with a maximum of 8 GB memory supported. 16-32 GB is more common. One exception would be the dirt cheap Celerons used in cheap Chromebooks, such as the Celeron N3050 [intel.com] which only supports 8 GB. But those Chromebooks will only have 2-4 GB of RAM that is not user replaceable anyway.
If ECC support is desired, you should probably wait for mobile Ryzen, although I don't know if it will actually support ECC. This [staticworld.net] is what AMD is promising for mobile Ryzen vs. 7th gen APUs (Carrizo).

I couldn't find anything about slots in the specs for the Inspiron 11 3000 [dell.com]. All that page says for memory is "2GB, DDR3L, 1600MHz". Does that mean it has only the soldered-in RAM and zero slots?

There should be a configuration [laptopmag.com] with 4 GB of RAM but oddly there is no 4 GB option on the page you linked.
The product looks a lot like a Chromebook. The Celeron N3060, 32 GB of eMMC memory, 2 GB DDR3L, 11.6-inch 1366×768 screen, and 720p webcam are specs that can be found in the low-end Chromebooks. Which don't have user upgradeable memory.
Celeron N3060 [intel.com] supports 8 GB max.
My Googling did not find much because most configurations in the 3000 series have a more specific model number like Dell Inspiron 11 3147.
So I decided to use the Dell chat. The rep says that you can add RAM to it manually. Here's the transcript, you can choose to believe him or not:
I went back to the list of user manuals [dell.com]. The specs seem similar to the Inspiron 11 3157 [dell.com]. It lists only on SODIMM slot and it says only 2 or 4 GB is supported.
That may be close. I found the Dell page [dell.com] for that model. It says "Sorry, that system is no longer available." But the header is the same generic "Inspiron 11 3000 Series 2-in-1" like the page you linked me.

Try it again. My experience with online chat help (not with dell) is they will give conflicting info.

Nowadays I use youtube to figure out stuff like that: https://www.youtube.com/watch?v=2kbHZjWZlj4 [youtube.com]
I won't rely on standard "support" since too many of them don't know what they are talking about. Some may lie or post unrelated/useless answers to have their stats look nice.
I might trust enterprise level support more, might have no choice if it's for stuff I can't find youtube videos for.
The other advantage of the youtube video is you can see how difficult it is and decide to buy a new device instead... :)

I wouldn't totally trust Youtube either. Not the fault of the guys who post the videos on there, but Dell is (or at least was) pretty notorious for changing the internals of systems without any notice or change in model number. So while you might find some guy posting pictures of the internals, you could open up your computer with the same model number and specs and find a totally different board, with different chipsets, numbers of slots, etc.
