Mostly JavaScript.
I'm running FF 60.2.2esr and displaying some ancient html (2001) with static pages containing text and photos. Top shows "firefox-esr" (7932) most of the time, "Web content" (7988) infrequently, and "file:// Content" (8026) perhaps a little more often (it's difficult to judge). These processes pop up almost regardless of when I click to add another tab to the collection that are open. ps ax shows the following list of processes: 7932 pts/17 Sl 0:33 firefox-esr file:///home/david/…the index page….html 7988 pts/17 Sl 0:02 /usr/lib/firefox-esr/firefox-esr -contentproc -childID 1 -isForBrowser -intPrefs 235:1| -boolPrefs 36:1|261:1|301:0| -stringPrefs 2 8026 pts/17 Sl 0:07 /usr/lib/firefox-esr/firefox-esr -contentproc -childID 2 -isForBrowser -intPrefs 235:1| -boolPrefs 36:1|261:1|301:0| -stringPrefs 2 8095 pts/17 Sl 0:00 /usr/lib/firefox-esr/firefox-esr -contentproc -childID 3 -isForBrowser -intPrefs 235:1| -boolPrefs 36:1|261:1|301:0| -stringPrefs 2 I've not observed 8095 in top at all. There's no java/css or anything like that. I did notice that if I hold down Ctrl-PageUp (ie circulate through tabs), 7932 and 8026 stay firm at the top of top. When I close all the tabs and leave open just the Mozilla Firefox start page that displays the one-inch icons of sites I visit, PID 8026 disappears, and it's easy to see that 7988 (Web content) is processing the icons as I move the mouse over them. > > > Killing them off won't help.

I would understand your writing the last sentence with the word "secure" (though I would wish to know which insecurities you're troubled by), but not as written here with "stable". I'm finding stretch's FF Quantum very stable so far. Is this because I don't use a DE, perhaps? Cheers, David.
