Firefox Slower to Launch in Windows 10

Callender said:

Well firefox writes to disk (page file) if not configured to only use RAM so fixed or small page file might just be an issue. If you don't want to check it's your call. If you know what is not the problem perhaps you could list everything that you have ruled out.

In the meantime see if this launches any faster: Basilisk web browser

Ok, I'll try changing the page file.
Edge launches in a fraction of a second though...

Tried that and still no results. Basilisk launches slightly faster than firefox, but not as fast as edge.
This might have something to do with windows rather than firefox itself. I noticed a slightly quicker launch when I open it from the installation folder. I also have a similar issue with file explorer. It's a little slow to lauch from the taskbar, but is fine when launched from start menu. Firefox might be a fraction quicker from the start menu too, but I can't be sure.

Callender said:

Okay I reckon that you're correct. I can't test start menu or file explorer because I use replacements for both!

What's the start menu replacement you are using?

Callender said:

I don't know if anyone suggested this already but exit Firefox and launch in "Firefox Safe mode"

WinKey + R then type

firefox -safe-mode

Press Enter.

If it's a lot faster then there must be profile/ addon issues.

I doubt if it will help since the profile I uploaded should have worked okay.

There's that dialog box that pops up asking if you want to start in safe mode, so I can't really say if there's a change. But I tried with add ons disabled and it was the same.

Callender said:

I'm going to take a guess and suggest switching DNS lookup:

This one is okay:

New Cloudflare 1.1.1.1 fastest, privacy-first consumer DNS service - Windows 10 Forums

Reason: Lookups should be faster so in theory browsers will launch slightly faster because connections take a little less time to resolve.

Do you also happen to make use of a large HOSTS file?

Reason for asking: Edge will require DNS Client Service to be running but for other browsers there will be a slowdown if the service is enabled when using a large HOSTS file.

You could still post the info requested here:

Tried switching the DNS. There wasn't any noticeable change. Although cloudflare and my default DNS appeared to be quicker than openDNS which was using before.

Also if you don't mind type about:support in Firefox address bar and in the window that opens choose "Copy text to clipboard" and paste it here. Thanks.
