I downloaded both Firefox Portable Developer Edition and vanilla Portable Firefox, but just the vanilla one works. Dev doesn't seem to be able to load pages, the page just stays white and the pinwheel on the tab just keeps spinning. Any idea what's going on?
Could you please provide some more details including: full install path, OS version and whether it is 32 or 64-bit, actual Firefox Dev version and build date from the About window (it will be different depending on when you install it), what language you have installed, what specific pages are affected.
You can also just re-install it over itself. It's built nightly and occasionally a build will be broken due to it being an Alpha quality build.
Sometimes, the impossible can become possible, if you're awesome!
Running on Win7, 64 bit.
Path is just "I:\PortableApps\FirefoxPortableDeveloper"
Version is 48.0a2 (2016-06-02)
Anything external is affected. Google, FF Sync, anything.
It's English. I just hit the big download button that's the same as the other apps.
