Firefox browser slow and laggy since update 53.0
Updated to 53.0 a few days ago and browser has been very laggy ever since. Sometimes the lag is unbearable and I have switch to another browser.
I have checked some other threads here and one suggested changing "network.http.pipelining" and the same one + .ssl to "true", but that didn't fix it, so I reverted it.
I also have the impression that my memory usage has been higher since the update, but I am not sure about that. For example, I have had my browser open for 10 minutes now and memory usage is 650 MB.
I have had this issue before with another Firefox update, but it fixed itself after a few days, or perhaps Firefox released a fix at that time. I'm using Windows 10, 32-bit. Please don't suggest loading in safe mode as if that is supposed to be the solution.

Start Firefox in Safe Mode by holding down the <Shift> (Mac=Options) key, and then starting Firefox. https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there? ++++++++++++++++++++++++++++++ https://support.mozilla.org/en-US/kb/firefox-slow-how-make-it-faster

When multi-process windows in Firefox is enabled then Firefox will use more memory and may be less responsive. Try to disable multi-process windows in Firefox to see if that has effect.
You can disable multi-process windows in Firefox by setting these prefs to false on the about:config page.
- browser.tabs.remote.autostart = false
- browser.tabs.remote.autostart.2 = false
You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
@Cor-el: Tried your solution first, but that didn't help. Important to mention might be that one of the two was already set to false.
@FredMcD: Firefox works fine in safe mode. Does that mean it's one of my extensions or add-ons that's causing the lag?
Type about:preferences#advanced<Enter> in the address bar. Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.
Type about:addons<enter> in the address bar to open the Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)
On the left side of the page, select Appearance. Then select Default.
Now restart Firefox.
It could be the work of one of your add-ons. Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)
In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.
Some added toolbar and anti-virus add-ons are known to cause Firefox issues.’’'Disable All of them.
If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.
Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.
Hey, I have played around with the different add-ons and it's the McAfee WebAdvisor add-on that was causing all these problems. I have enabled the other add-ons and the browsers work fine now with the McAfee one disabled.
Thanks for your help.
Contact McAfee and ask about this. Let us know what happens.
After last update my firfox GUI it has become very slow too.

Start your Computer in safe mode. Then start Firefox. Try Safe websites. Is the problem still there?
