Firefox Portable

Not launching java

Submitted by OFox32 on April 18, 2018 - 8:27pm

I have been using portable Firefox 51 and portable Java 8u161 for the past few months and it's been working great until yesterday. Now I have to have Java 8u171 for it to work. I don't have Java installed on my computer so it's not a conflict. I am using a mozilla.cfg file to configure firefox to not update or look to the Operating system for addons. I can't use java 8u171 because the app is not compatible with it, it requires java 8u161 or 8u152. if I visit and click verify java it just shows a blank white spot.

Can I force 64 bit?

Submitted by Lorry on April 14, 2018 - 4:39am


I have 2 versions of Firefox Portable running on this Windows machine and one loads as 64 bit, and the other as 32 bit. Whatever I do to the second one, it always loads as 32 bit. The ini files are the same, I have even (in desperation) tried changing the FirefoxDirectory to App\firefox64 but nope, even though the image shows as firefox64/firefox.exe it's still a 32 bit image.

Is there a way to force it to load up the 64 bit one? An opposite of AlwaysUse32Bit=true maybe?

This is driving me kind of insane because there seems to be no logic at all to it.

[Fixed] FirefoxPortable.exe launcher does not remain running while the Firefox updater runs

When doing an update using Firefox's internal updater running within Firefox Portable, the FirefoxPortable.exe launcher does not properly remain running through the update and the app's close after the update. This can result in some empty directories and registry keys left behind on the local machine. Platform users that update via the platform's internal updater and users who manually download each release to update are unaffected by this issue.

Firefox Portable doesn't start - other portable apps work fine

Mysterious phenomenon on a Asus VivoBook S (Windows 10 Pro Version 1709, Build 16299.309, up to date, BIOS up to date): Firefox Portable - no matter which version, no matter which user profile - doesn't start. It pops up briefly and then closes again immediately. Not even a safe start (= with activated shift key) is possible. Permanently installed Firefox works fine, other portable apps - including browsers like Chrome, Opera, Maxthon, Seamonkey, Quipzilla - too. No problems on other laptops (Acer, Toshiba, HP).

Additional Profile folder created in the 'Users' folder causing issues

At first, I thought this was another instance of FF opening up due to the default GUI that opened until I figured out what was happening.

There is a problem with this other 'Profile' folder being created, buried in the 'Users" folder running Win7. It is not a duplicate of the customized folder within the actual program folder, but just a 'default' profile folder that doesn't get updated when the regular profile changes (add ons, etc).
There are 3 folders (only one seems to have data in it) buried in that annoying 'Users' folder in Windows (W7 specifically).
