Certain sites slow on Firefox 55.0.3
After updating to a certain version of Firefox, I have been experiencing problems on Mozilla Firefox with sites loading slowly. For example, listverse will load slowly on Firefox, but on Google Chrome, it loads fine. Clearing cookies does not even help. Can you help me solve this problem?

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

If you use Adblock Plus then consider to switch to uBlock Origin (ABP has been reported to cause issues).
When multi-process windows in Firefox is enabled then Firefox will use more memory and may be less responsive.
You can try to modify multi-process settings to see if this has effect.
- set dom.ipc.processCount to 1 if it is currently set to a higher value (4)
- disable multi-process windows in Firefox
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.
