Firefox Portable

Hello,
I'm sorry, probably my question was answerd earlier, but I can't found!
(I missed "sub-forum specified search feature" here)
Following:
I want install "FirefoxPortableESR_52.3.0_German.paf.exe" at memory-stick, for portable use.
I use local, persistent, a Firefox-Portable-Edition, updatet to V54.0.1 (64Bit).
Now, the Installer of the "FirefoxPortableESR_52.3.0_German.paf.exe" refuse the installation while the local firefox is running!

Both firefox 54 and 55 are, on USB stick, fast in anonymous navigation but slow in not anonymous navigation !! It's a disappointment .... Why ??

Hello

While browsing pixiv with the firefox portable the site layout became borked losing some of it's several functions.

Context:
Messed up layout - http://imgur.com/n3BnFRr http://imgur.com/xzeS7oh
Correct layout - http://imgur.com/40YqtXV

I just noticed this folder :
C:\Users\XXX\AppData\Roaming\Mozilla\Firefox\Pending Pings
left behind after exiting FF portable.

Maybe it needs to be cleared up like crash-reports.

Noticed it in v55.

Never done a portable before, so I know absolutely nothing about this. Basically, I want to get Firefox 3.5 onto a flash drive, along with some add-ons and extensions. Is there any sort of step-by-step instructional available for us total greenhorns? Can someone point me in the right direction? Thanks!

- Copied FirefoxPortable.ini from Other\Source to the folder containing FirefoxPortable.exe and made sure all the entries in it were correct.
- Tried to run "FirefoxPortable.exe -p" but found out later that it was not portable.
- Made an %appdata%\Mozilla\Firefox\profile.ini file and a Profiles subfolder (both empty) under that folder.
- Did not tamper with the App folder, except for deleting Firefox64.

Nothing worked. This seems to be a new problem as I couldn't find any solution on the Web.

Dear all,

I've being trying to run Firefox Portable (versions ESR 45.7 and regular 45) with jPortable (versions 8 update 91 and 121) with no success.

I'm capable of seeing the plugin available in the browser but when I try to run an applet (such as in https://www.java.com/en/download/installed.jsp) it just stays blank after I click on "Verify java version".

Some time later a message appears saying that it wasn't able to detect the installed version.

Any idea what is happening?

Could be as I had trouble with this one vendor on-line, just the one, as Amazon and the others seem unaffected. So below is a copy and paste I had with their help desk;

Wouldn't it make sense to have Firefox Portable set the cache folder to a local path and delete it on exit by default? I wonder if it would improve the performance of Firefox Portable...
