Firefox Portable

Hello,

I'm trying to use an addon called Scrapbee with Firefox portable v71.

This addon uses the Native Messaging Hosts parameters to refer a JSON. On Windows, this is usually done through the registry with the following keys :
- HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\NativeMessagingHosts\scrapbee_backend
- HKEY_CURRENT_USER\Software\Mozilla\NativeMessagingHosts\scrapbee_backend

Hello,

Is it possible to use non-portable Firefox/SeaMonkey with a PortableApps Firefox/SeaMonkey profiles by using the "-profile" command-line option?

So, for example, suppose we have our non-portable Firefox/SeaMonkey installed in the following locations respectively:

C:\Applications\firefox-52.9.1
C:\Applications\seamonkey-2.49.5

And also, suppose we have PortableApps Firefox/SeaMonkey installed in the following locations respectively:

C:\PortableApps\FirefoxPortableLegacy52
C:\PortableApps\SeaMonkeyPortable

Hello
After updating 71.00 portable, the bookmarks of the favorite bar are displayed horizontally, preventing access to all bookmarks available. To get around the problem, I have to create and insert an empty folder as firts element of the list , so they are displayed correctly, i.e. vertically. Already tried to start Firefox with disabled add-ons.
I tried to get the previous version (I backup everything ...) and when update to 71.00 the problem occurs. Strange that it just happened to me.
Any suggestions to fix the problem?

When I disable the enterprise policy, firefox will instantly try to update me to the latest version 71.0, but I only want to update to 69 or 70, but not 71.0, so how can I do that on an existing portable installation?

Is there a .mar file I can use to perform a manual in-place upgrade?

So I've been using Firefox Portable version 55.0.2 for quite some time, and I'm very happy, thank you for the work you do.

I'm wondering, is there a way for me to "hack" the browser and completely disable the download box/dialog?

For example, see this picture:

it does not show show in plug ins

I had firefox portable since a long time at work; some other day, a stupid admin decided to put some registry keys to disable some features of Firefox. Whenever i start it, it keeps going on some dumb "workplace intranet" i don't care about, passwords can't be remembered - nor used, and about:config show a lot of options as "locked".

The issue starts from Firefox 69 and persists on Firefox 70.0.1. It used to work properly on old versions. However, an error window prompts from version 69 saying my profile may be missing or cannot be accessed. Is there a particular reason why Firefox Portable have to access %AppData%\Mozilla and %LocalAppData%\Mozilla in order to start up? If those permissions are not necessarily needed, could you please fix this? Thank you!

I have Firefox installed and despite closing it and opening Firefox Portable when I click on a pdf for example or an html file it opens the installed firefox instead of the portable one. I have not set "Multiple Instances" to true and I understand that being it disabled is the default. Do note I have updated the portable "installation" to the latest portable release.

Edit: forgot to add I'm running it in W7 x64.

Once again FF updated automatically and removed all user controls over the process. This time, in addition to messing up add-ons, it also screwed up its default settings and would not stick as the default program. TB would not open FF Portable and resorts to the generic FF without my profile on PC. Time to return to a FF Portable old version? I'm sick of fiddling with "improvements" no one asked for! Last attempt at fixing it...
