Firefox Portable

I have been trying to install Firefox nightly 64 for a while but I always get a "file not found" error during the installer execution.
I have tried some older versions and I get the same error.

Is the support for this version officialy dead ?

Hi.
Can't upload pics/videos to Facebook (in safe mode also does not upload).
IE11, Opera works, but FF - no.
Can you help me?

Hello John and All.

I am running FF portable 47.0 on an Windows XP system. All the Add-on's (plug-in, extensions) show (disabled). Some seem to be running but still show disabled. How can I correct this on my list to make certain all is up to date and working properly. I also assume that some are no longer compatible with the newer program. Thank you.

Launcher 2.0.4.0 fails to load nightly after oct 7, prior to oct 6, it works fine.

I use Portable Apps on my hard drive (to keep from getting tangled in the registry so I can be portable if I need to). My default email program is set to Thunderbird Portable in both Windows 10 and FF Portable. But if TB Portable is running (as it almost always is) and I click on an email link on a webpage, instead of just opening a composition window, I get: "Another instance of Thunderbird is already running. Please close other instances of Thunderbird before launching Thunderbird, Portable Edition." Is there a setting I need to fix somehow?

After opening Firefox Portable (v49) I try to open another site from my favorites (or open a tab and enter a url (e.g. www.google.com) directly. The spinning icon just spins and the site doesn't open. If I copy the same url entered into Chrome or IE the site opens immediately. I use two add-ins, Ghostery and ABP. When I try to open FF without add-ins I can't. When I disable those add-ins, via the FF menu, this doesn't seem to help. I have no proxy setting. After a while (15 min or so) sites start responding more quickly.

Hi,

Since the update to Portable Firefox 49, it is refusing quite a lot of pages or loading them with a messed up formation with the explanations that their are "insecure".

Any word on when the Firefox non-Release channels will be updated? (Or the Beta channel anyway.)
Should the request be added to the following thread, or is that just for the Release channel: https://portableapps.com/development/outdated
Or is it safe to assume that you're already working on them since most of the channels increment at the same time?
Thanks.

We have been running Firefox portable now for years with much success. Lately we have been having some problems. We currently have version 47 portable deployed with Java 1.8.101 and all is working well. (Other than when you check the version it says there are no updates)

I have updated to version 48 and Java still detects under the plugin fine. Once I update to version 49 java and a few other plugs are no lover visible under the plugins tab on Firefox.

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 ?
