Firefox Portable

Hello, I am unable to find the legacy versions of Firefox Developer Edition. https://portableapps.com/apps/internet/firefox-developer-portable
I know where the legacy versions of other builds are. Does anyone know where those are archived once a new version comes out?
Thank you.

Since no one else has mentioned it that I have found, it may somehow just be me, but after the latest update (file version 2.1.4.0, 66.0.3), PP Firefox will not load Gmail, as it did before the update. It just goes to a blank, white screen.

Win 10 64-bit
Same USB, E:\PortableApps\FirefoxPortable
Same computer

Haven't tried it on different machine yet. I will update if it is machine-specific.

Update: It is not machine-specific. It is showing a white blank screen for Gmail on all machines.

Latest version of FF Portable seems to be very unstable. Pages do not load correctly, FF freezes up frequently requiring re-start, dumps my bookmarks, new tab content won't load despite assigning the settings I want.
WHy does each subsequent version seem to be more unstable than the previous one?

I just have two suggestions for the PortableApps Launcher for Firefox, both of which concern the AllowMultipleInstances parameter in FirefoxPortable.ini.

I clicked Help=>About to check which version I have and it started updating itself!
Until now it always had a message that this feature was disabled.

What will happen once I restart Firefox? Will the portable version still work fine?

Hello,
Is it possible to use FF portable plus 2nd profiles from Google Drive? Or will that leave a footprint?
Thank you
(Sorry to mod for double posting, but I thought it was a different topic)
P.S. I've installed the folder on Drive, but it looks like it's not possible to open the .exe file.

hi
i have imported password from firefox 56.0.2 installed to firefox 62.0.2

well when i want to login on a site it doesn't show my password and it doesn't prompt when i want to save them
for example site google.com , login -> firefox 62.0.2 doesn't show any password

is there a way to enable them?
i guess are in the about:config some flags to enable

Hi,

First, thanks for this gem "PortableApps".

I would like to report a possible Bug at Firefox Nightly Portable 64-bits latest version, in Windows 10 latest version: Add-ons settings and content are not portable.

Installed add-ons may appear at Nightly' "about:addons" page, but add-ons are inaccessible, no settings, no contents.
Even inaccessible at "about:addons", sometimes installed add-ons work. But considering that they are inaccessible and add-ons also don't appear at NavBar, TabBar, Menus etc, it is impossible to use them.

Hi all,

Sorry if this has already been asked, I couldn't find it.
I need several social accounts to have the localized versions, and I therefore use proxies.
Would it be possible to have several installs of Firefox on a usb stick, each with the different proxy settings?

Thanks in advance for your advice
