I was registered default browser to Firefox Portable.
used "RegisterFirefoxPortable.exe"

Hello everybody

The company I work for (Identitas AG, www.identitas.ch) has a very large Silverlight Browser Application which is used by about 60‘000 users.
By 01.01.2017 all major browsers (except Internet Explorer) will not support the Silverlight plugin anymore.
That’s why we are migrating our application away from Silverlight, but we will not be able to finish this task in time.

I'm running Firefox Portable x64. I need Java support. While Java (both 32 and 64 bit) are installed on the machine in question, my understanding is that Firefox Portable requires jPortable.

I understand that 32-bit plugins won't work in a 64-bit browser. However, since jPortable is available in a 64 bit version, I'm assuming that Firefox Portable x64 should be able to work with it - but I'm not having any luck so far.

What am I doing wrong?

For the past several months, downloads of Firefox portable routinely fail, or take excruciatingly long to download. This occurs in either the 'automatic' update within the Portableapps platform, or if I try to download the paf.exe file directly from Sourceforge. I only seem to have this issue with the Mozilla portable apps, Firefox and/or Thunderbird. I have no issues with any other portable apps I use. Other large downloads,such as Chrome, are quick and error free. Is this a Sourceforge issue?

I've got a bunch of searchplugins that I have added to my desktop version of Firefox (45, Windows 32 bit). Wondering where to put them in the portable version.

I'm interested to inform me how can I update the adobe flash player on my mozilla firefox portable.
here: https://portableapps.com/support/firefox_portable#plugins there is guide that mentions an extension, but the flash extension doesn't work at all, it says that it is corrupted!

Currently not intended for a portable version?

Only problems with Firefox since version 44.0. Most of the errors are already addressed in other threads but I got an error saying “can’t load XPCOM”. I have done a check disk from Windows Vista and it did some repairs of broken items on the external hard drive. It didn’t make any difference. Then I followed advice I found online for the regular Firefox and uninstalled everything, after taking back up, of course.
