I think each Firefox tab is a new process. It stops the whole thing crashing if one tab has issues.
Personally my first step would be to upgrade to windows 10. You can buy a licence for under a tenner or I think there may still be an option to upgrade for free.

Sounds like you have plenty memory (RAM) so what about the hard drive? Insufficient memory errors can refer to the physical disk, possibly caused by memory leakage (it isn't freed up after use for some reason so you run out of memory).
Firefox on Win7 isn't usually a memory hog so if you are seeing many rather than a few instances of the browser that can indicate malware at work, so check that out.
Win7 will be end of life\out of support early next year so might be wise to look at migrating to Win10 soon and get new software for the scanner.
I am having out of memory issues with a Win7 laptop, feedback on this would be appreciated -
the thing has been working fine the last years, as a light-duty work machine (internet, music, very basic photoshop work with small-ish files).
Now in the last couple of weeks / months I'm running into memory issues quite regularly.
PS has updated in the meantime, as has the Firefox and the Windows 7.
I'm actually not having noticable performance issues due to lack of RAM, it's rather that usually Winows is now telling me every now and then it needs to close applications (usually Photoshop), as it's low on memory.
When I look at the usage in task manager I'm sometimes baffled at how many seperate Firefox processes there are, yet added up it still does not seem critical.
I did just up the memory from 4GB to 8GB, sadly the issues still persist.
Any ideas?
