Firefox Portable

Dear all,

I've being trying to run Firefox Portable (versions ESR 45.7 and regular 45) with jPortable (versions 8 update 91 and 121) with no success.

I'm capable of seeing the plugin available in the browser but when I try to run an applet (such as in https://www.java.com/en/download/installed.jsp) it just stays blank after I click on "Verify java version".

Some time later a message appears saying that it wasn't able to detect the installed version.

Any idea what is happening?

Could be as I had trouble with this one vendor on-line, just the one, as Amazon and the others seem unaffected. So below is a copy and paste I had with their help desk;

Wouldn't it make sense to have Firefox Portable set the cache folder to a local path and delete it on exit by default? I wonder if it would improve the performance of 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?
