More than one process is normal for the current Firefox. http://www.ghacks.net/2016/07/22/multi-process-firefox/

Multi-process Firefox is codenamed "e10s". https://wiki.mozilla.org/Firefox/multiprocess

Try to disable multi-process tabs in Firefox. You can disable multi-process tabs in Firefox by setting the related prefs to false on the about:config page.

browser.tabs.remote.autostart = false browser.tabs.remote.autostart.2 = false

Type about:config<enter> in the address bar. If a warning screen comes up, press the I Accept the Risk button. At the top of the screen is a search bar.

I have stayed current with FF releases. The machine in question worked just fine with FF 56 and previous. I will make the assumption that multi-process was default in that release. I have not changed any options manually before.

Still waiting on answer to my question about ESR.

Means a bad FF install and did you remove all previous FF and FF folder before install FF57+? If not then you most likely have bad install leading to leakage RAM. I did that and have now such issue.

Still not clear what ESR is and its support lifetime

To WestEnd: Sounds pretty drastic to me. What about my bookmarks and other personal items?

To Fred: Yes I already reviewed those items. As ESR works for me and NOT 57 I ask again what is the difference? A year from now when ESR "expires" then what? I am a personal user. I have been in the IT field for 25+ years.

Do I just keep trying 57 every now and again hoping it will work?

I called for someone to help with your questions.

If you had scrolled down on https://www.mozilla.org/firefox/organizations/ you would see this.

Try to disable accessibility services in Firefox 57+.

• Options/Preferences -> Privacy & Security -> Prevent accessibility services from accessing your browser
• https://support.mozilla.org/en-US/kb/accessibility-services
• http://techdows.com/2017/08/firefox-57-prevent-accessibility-services-accessing-browser.html

You can try to modify multi-process settings to see if this has effect.

• set number of content processes to 1 if it is currently set to a higher value (4)
  Options/Preferences -> General -> Performance
  remove checkmark: [ ] "Use recommended performance settings"
• disable multi-process windows in Firefox

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

My frustration level is raising. Some posters have pointed me in positive directions. Over have not. I will start all over again.

I have been a long time user of FF. Kept current on updates. This came to a disastrous halt when 57 became available. In quick order machine became unusable. Downgraded to 56. FF worked again. I was informed this was the wrong solution. Directed to something called ESR. As I have stated multiple times I reviewed ALL the articles and ALL the items in the articles. I am a single personal user. As ESR worked and 57 did not I asked what I thought was a simple question. Why? To be more specific what is the difference between ESR and 57? Is ESR the "same or similar" code with option(s) disabled? My initial impression of the articles was ESR was a "temp fix" while the issue(s) with 57 were researched and addressed. I now am getting the impression that ESR and FF are similar but different tracks. As I have tried to ask before will I use ESR "forever" or will I be able at sometime to return to using "regular" FF? Yes I have seen updates that this forum is users not developers.

When I was full time working I would prefer to talk with the user regarding their problem/issue. Trying to use only written word create its own set of issues.
