Firefox Portable

Hi,

Recently I upgraded my Firefox ESR to v52.2.1 and notice I can't run more Firefox instances despite the fact i have FirefoxPortable.ini set like this:
---
[FirefoxPortable]
AllowMultipleInstances=true
---

Firefox itself presented the error Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window

Did some testing and found that this version only accepts multiple instances if the -no-remote option is not passed to firefox.exe by the portable launcher.

i want it to write to custom temp folder when open firefoxportable from my taskbar without modify user var environment.

Hi,

In a local Firefox installation is it possible to set preferences at /Firefox/defaults/pref/all.js (or other name js file). It is useful for setting preferences to remain after every restart overwriting the user settings, or setting a mozilla.cfg file to lock some settings. We need it to lock some proxy settings before distribute the portable Firefox to our users.

I tried it with Firefox Portable and it doesn't seems to read Firefox/defaults/pref/*.js files. How can I do it with the Firefox Portable?

Thx

After installing Mozilla Firefox Developer Edition v55.0 Beta 2, I get this error when starting FirefoxPortable.exe:

ERROR: firefox.exe could not be found

My OS: Windows 10 Home x64 v10.0.14393
Install path: D:\PortableApps\FirefoxPortableDeveloperApps\
New install, tested both English and Dutch version.

hello. I would like to know which version to dl to use with win xp. The most recent Mozilla Firefox, Portable Edition 54 does not load, although I see the splash screen. I read somewhere about possibly using an ESR version? Also any thoughts on java for an xp system. thank you.

Soon after upgrading to Firefox 54 Windows 10 presented me with a firewall warning: http://imgur.com/a/8ymTg

Any idea if it's related to the upgrade?

How does PortableApps treat firewall exceptions anyway?

Just wanted to let everyone know that LastPass has discontinued the add-on for Firefox Portable. Problem is, that the add-on doesn't connect to the safe anymore after typing in the master-password! It's now only working with the installed version of Firefox. In my case it doesn't make any sense to continue using this browser now. Is there an alternative password manager that works as easy as LastPass and that works with the portable version of Firefox, Chrome, etc.?

Hi there,

fresh and new to this forum as well as Firefox Portable. We´re challenged to publish Firefox portable for our users. So the Folder with the files is saved on a network location with rw Access for the users.

The user starts the firefox.exe from App\Firefox\ how can we set defaults like "no Browser Check" and so on, or is it necessary to start the FirefoxPortable.exe from the root directory?

Tried to modify the pref.js but without success.

Everybody help is much appreciated.

Thanks!

there is a nice explanation here of how to switch languages of FIREFOX PORTABLE on the board here (Method 2: Language Packs and Locale Switcher - Download the Locale-Switcher extension ... install it - Download the language pack - install it - restart - TOOLS / LANGUAGES and select the language - Restart).

What does it mean Firefox Portable Rev 2?
