Firefox Portable

In our environment (Microsoft Windows) it is not possible to start firefox (Version 50.0.x) from a static mapped network share. (same effect with UNC)

Is thsi a nown Issue? Is thsi a Problem with a Microsoft Security Update? I there a workaround?

I tried to use Firefox Portable 50 with Selenium 3 and geckodriver (https://github.com/mozilla/geckodriver).
Firefox Portable starts but then nothing happens. See the following issue which exactly describes my problem: https://github.com/mozilla/geckodriver/issues/365

Any help is welcome.

Hello

I am really fed up with the horrible way Portable Firefox manages new versions. For a large number of last version updates, this happens:

I cannot find this in the Mozilla forums. My problem is that I use an extension that in the recent versions do not work the way I want it to, whereas not so recent versions work just fine. But of course Firefox want to update the extension - so how do I turn this off for this extension?
And yes, I've taken this up with the extension creator(s) but there they blame Firefox.
Windows 7, Firefox Portable 49.0.2

Hi everybody,

I'm running into a weird problem with the latest version of Firefox portable. In version 49.0.x, the program stops responding and is never loading.
When I start it, I can see in my task bar (yes, Windows system) 2 windows for Firefox: 1 for the program itself (where the home page stays blank indefinitely - at least 5 minutes, after that, I kill it) and 1 I can't open.
I've already tried several ways to install it without success.
And as I don't see topic about this issue in the forum, I suppose it has something to do with my own installation.

I run Xp sp3 with FFP 47.0.1 and it ask me to update to FF 47.0.2. I tryed to find FFP 47.0.2 version on Portable Apps WEB page (Sourceforge), but I've found FFP 49.0.2. If I use Update Software Window (Show Other Update Info) it redirect to mozilla FF WEB page, where FF 47.0.2 seems to be available since November 01, 2016. Could someone let me know how to proceed? Many thanks in advance.

Undo Tab Close function is not working in portable FF ESR 45.4.0 (Ctrl+Shift+T).

I can't open closed tabs like I did in standard FF ESR 45.4.0.

In the open tabs drop-down list Undo Close Tab appears disabled.

This may be a problem with my environment, but I thought I'd throw it out there anyway.

I've started getting the follwing message screens on several sites - Dropbox and Google+ to name two.

1. firefox 49 actually check at startup if SSE2 CPU instruction is available. it issues an explicit statement, and does not continue, if that instruction is not available. I guess Windows 7, and newer, can not be installed on such CPUs. It there fore concerns only XP. Did I miss portableapps explicitly mentions that requirement on relevant web pages?
