Useful add-on but... Rated 3 out of 5 stars

Fail on user session load on every browser start. So it opened the dialog to recover session, but it's not good.

Works but only the first run Rated 5 out of 5 stars

Developer should add -silent in the description and start minimized.

I use an autohotkey script that detects when I close Firefox and waits 15 secs then runs the shortcut -preloader -silent so I open Firefox fast all the time not just the first time.

what about HKLM/Run,and what about firefox -silent Rated 4 out of 5 stars

I haven't test it yet for I dont reboot often

but will it work as well when start through

and what's the different between
"firefox -preloader"
"firefox -silent"

Wow! What a speed increase. My primary PC took 3-4 seconds to load Firefox after a cold load and 5-6 seconds on my backup PC. Installed the preloader and now it takes 1.2 seconds to load on my primary PC and 1.1 on my backup PC.
Great work.


It starts, then it disappears Rated 2 out of 5 stars


I had the idea to run "C:\Program Files (x86)\Mozilla Firefox\\firefox.exe -preloader" from the console, and the following is what resulted: INCLUDE ScriptlessBGThumbs: [Exception... "Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIXPCComponents_Utils.import]" nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)" location: "JS frame :: chrome://noscript/content/ScriptlessBGThumbs.js :: TOP_LEVEL :: line 3" data: no] undefined Failed to find nss3 in installed directory, checking system paths.

Optimize the preloader Rated 5 out of 5 stars

Perfect. I changed it to "Run minimized" and added -silent to the command line: C:\Program Files (x86)\Mozilla Firefox\Firefox.exe -preloader -silent
Now Users do not see anything when the computer starts and are just amazed how fast Firefox loads.

Super! Rated 5 out of 5 stars

Nice work! I do like such addons that increase startup time or perfomance. Is there similar addon for thunderbird?

Windows 8, Firefox 26

Rated 5 out of 5 stars

works great with linux

startup-time reduced from 7.5 sec to 3.8 sec (both after a fresh start)

using firefox 25.0-1 and linux 3.12.0-1

Rated 5 out of 5 stars

It works for me on Linux: FF 22 running on Slackware 13.1. I use the XFCE desktop and all I had to do was add it to the autostart list in Settings > Sessions and Startup. It does what I wanted and doesn't seem to interfere with anything. It's a good plugin.

Not working Rated 1 out of 5 stars

It is not working with firefox version later 13.0. After the addon was installed and after making the target field changes, the firefox is not loading at all.

funktioniert nicht mit aktueller Version

Rated 5 out of 5 stars

An excellent add-on! FF loads noticeably faster here on my Win 7 netbook.

I don't know what problem the one-star reviewer had... Did he remember to do the 2nd part of the installation, as described above? It's worth the effort.
