Firefox Portable

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?

Hi!

I tried to create a chrome folder inside the Profile Folder and put my userContent.css there, but the file didn't work. I ejected the USB and stick it again, nothing. Do I have to put it in another folder or it won't work at all?

Regards!

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".
