Firefox Portable

HI @all,

I have installed Firefox on several PC´s. These PC´s are all clones of each other.
On some PC´s Firefox automatically detectes an Update and askes if it should be installed.
But on some PC´s Firefox doesn´t detect an Update. In the Menu "About Firefox" it checks for Updates and says that Version 47.1 or 48.2 is newest and no Update is availible. The actual Version is 49.0.
How can i fix this ?

When privacy settings - "Always use private browsing mode" with options "Accept cookies from sites" - see the screenshot - http://imgur.com/03SVvxt, I add site in exceptions (with option "Allow"), save changes, but after restarting the browser, there are no one exception. Is there a solution?
Browser - FireFox Portable 48.0.2.

Yesterday (9-Sep-2016) my bookmarks in FFP suddenly disappeared. In addition, when I click the bookmarks icon, the panel of bookmarks no longer appears on the right side of the screen. If I select Show All Bookmarks, a "Library" window opens, but is empty. If, from that Library window, I take the option to Restore (under Import and Backup) , I get a pop-up saying "Unable to process the backup file". I tried numerous back-ups that Firefox had created, but got the same message every time.

I want to use an older version of FF portable (older than 48). There used to be a list of older versions (years ago), where one could use any from that list. I can't find any trace now though. Are they still available? Been a while since I used the forums - never needed to - 'til today.

Hi,
I just noticed that addons in both my Firefox portable instances didn't update for more than a month whereas the same addons in my non portable Firefox installation updated correctly.
So I tried to manually update the addons in my portable Firefox but I got errors: "There was an errror downloading <extension_name>" for each not up-to-date addon.
In the "Tools > Web Developer > Browser Console", there were more details:
"addons.cdn.mozilla.net:443 uses an invalid security certificate.

My Portable Firefox has been working fine till today, it stops loading everything (add ons, history, cookies, storage, etc.), basically all profile.

When I try to login to the sync account, it says that cookies and storage have been disabled, but under privacy, everything is set to accept. Tried installing new copy. Still the same thing.

What had happened with my firefox? All I did last was just quit the app, and start today.

Help. Anyone?

Just a heads up for those still using older PCs. Mozilla Firefox is dropping support for PCs that don't have SSE2.

If you are not sure about your PC, you can check with https://portableapps.com/apps/utilities/cpu-z-portable

In the 48.0 release notes, https://www.mozilla.org/en-US/firefox/48.0/releasenotes/

The reason I ask is that I tried to install this version from your website and got a failed warning. I guess apparently I need the portableapps platform to go with it, but I can't install it on an old encrypted IronKey USB stick.

Can somebody point me in the right direction for FF portable builds?

Thank you.

At least for users of old unsigned add-ons a good choice.

Trying to install by standard means - via the PAP.
“Download Error: File Not Found”... followed by a mozilla ftp path ref to the wrong version - 48.0a2. I believe that should be 49, as the PA page for FF Dev also indicates.

PAP = v14.1
OS = Windows 7
