I open the browser (homepage is google search - so a pretty empty space - but it makes no diff which homepage i use). And it takes a verrryyyyyyyy long time to load.

I have emptied cache etc etc etc, No viruses etc etc, Not caused by an add on....

And no, I dont want to do the 'reset' thing. (Why should I have to spend time every few weeks resetting all my Firefox preferences? This is a long standing BUG with firefox. Other browsers dont do this!)

How fix it? It seems to me that someone at Mozilla needs to address this bug. It's been around for a few years now.

more options Did you update Firefox to the latest version 64.0.2 January 9, 2019

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

64.0.2 is the latest. Why are you on 61?

You say it's not an Add-on (Extension) that is at fault. How did you determine this? What Extensions do yo have?

Click on the Windows icon 'Start' (bottom-left) and in the right column, bottom, click on Run. Enter in:

<center>DxDiag /64bit</center>
<center> (Skip the /64bit part if it's Windows 32-Bit.)</center>

...Wait until the green bar loads and disappears, then click "Save All Information".

Make sure your computer is not too 'LOW' on disk-remaining space. This will be a major performance problem if your remaining disk space is TOO LOW!
Example: At the moment, I have 37% space free. If you're way under 25%, then you're probably running into performance / Memory issues.
Windows-7 and Programs like to have plenty of free-disk 'breathing' room. I recently cleared over 75 Gigs worth to get me to about 37% of free disk space.

Perhaps you may wish to setup a ReadyBoost Flash Drive.
If you have a lot of Windows and Tabs and your FireFox Browser is set to Restore Session when you start-up FF, the following will help with conserving some Memory:

Go to Options. Edit or Insert in the URL Box About:Config and go there. Set the following Values:


browser.newtabpage.enabled; false

browser.newtabpage.enhanced; false

browser.sessionstore.restore_pinned_tabs_on_demand; true

This will preload only the last Tab you were parked on per browser window. The other Tabs from your Previous Session will load only when you click on them.

If you open a lot of browser windows, you can set the maximum 'remembered' browser windows higher than the default for your Restored Session. My max is set for 25:

<center>browser.sessionstore.max_windows_undo; 25</center>

Finally, I did the following FireFox adjustments for my old 2010 computer with the Performance settings in Options as shown in the image attachment:
