Am running LMDE 2, fully up-to-date and using Firefox 50.0.2 but Firefox has been really painfully slow for a while now - it's so slow to start, slow to scroll a page even with only one tab open, and takes a minute to type out a full word.
I've tried starting Firefox in safe mode, completely deleting my user profile and starting fresh, used "apt-get remove --purge" and then reinstalling firefox.... and still stupidly slow. Chrome is speedy, starts up fast, can run 20+ tabs without a slow-down in performance, no problem at all.
And my laptop is no slouch - it's 3 years old, has a quad core i7 processor, 8GB RAM and a Quadro video card. I also run LMDE 2 and all apps from a 256GB SSD card. The home directory is on a 500GB SATA hard drive, however. So I do expect better performance from Firefox so there must be something wrong - I'd really appreciate it if someone can give me some pointers as to what could be wrong please?
Here's the output from inxi:
