Hi Ebtrr-

I am so sorry that you are experiencing these issues. Lets try to get your memory issues under control. That's paramount to get the performance you expect. After that we will work on the GUI. I will present a series of actions that should bring you back under control.

PLEASE let me know whether these actions are beneficial or we need to proceed further:

First Action to Try

• First update your video card drivers directly from the manufacturer nVidia, AMD or Intel

• Make sure you reboot the computer

• Refresh Firefox by typing "about:support" in the url bar then clicking "Refresh Firefox" on the top right

• Close Firefox and restart the browser

• Test without any addons

Same problem here - massive memory use after upgrade from 56 to 57. Firefox was already (pre-57) using so much memory I had to upgrade from 4GB to 10GB and significant expense - just for FF. That satisfied FF and it finally started behaving and performing reasonably. With 57, it starts off using about the same amount of 56 but after a few hours, even hours of complete user inactivity, FF uses all the memory left on the system. It is using 5+GB as I type this. Of course the add-on which would provide diagnostic info on which tabs were eating all the memory (Sessionstore) no long functions on version 57. The restart add-on that would restart FF in one step and flush the memory back down to a reasonable level doesn't work anymore either. The wife is upset that her Facebook videos don't work anymore on 57. I hate the awful "Windows 10" look and you forced the tabs back to the top where they should never have been put in the first place. I ask myself "Self, why are you putting yourself through this?" I don't have a good answer. I don't care about bleeding edge performance, I need a browser that is reliable, handles a heavy loads with grace, and is extensible to my needs. That is what brought me to Firefox so many years ago. V57 is none of those. In fact Firefox 3.X could handle 60+ windows with multiple tabs with add-ons. What happened to that code? Now you get to about 15 and it's so draggy. I need a browser that works not one I need to debug and repair. I'm going back to 56 and staying there until and if Mozilla cleans up their act, and if not I guess I'll finally look elsewhere. I used Netscape before Firefox and Mosaic (remember that?) before NS and even used Cello. I've seen a lot of evolution, and in the last 5 years I have not liked where FF is going.

Asked when Firefox 57 was in Beta - has been answered for the "Owner".

Now that Firefox 57 has been released for a week (actually 8 days now), the time has come to retire this thread from active duty.
