Firefox Portable

problem ejecting USB drive after having run Firefox Portable from it

Submitted by anonymous_person on December 24, 2025 - 12:42am

So a while back I noticed that Windows was unable to eject my USB drive. I tried to use programs to find open handles or programs that might be open but it didn't help. I even bought and tried the program USB Safely Remove but it didn't help either. I did however find the cause to be Firefox Portable. I have tried with different USB sticks and also Firefox ESR. Here are the approximate steps I've done:

Cannot make FirefoxDE to run when modifying the executable & ini

I changed "firefox.exe" inside the App\Firefox64 to "firefoxde.exe" & at same time modified the launcher configuration file inside Other\Source, the FirefoxPortable.ini, I looked for the line: "FirefoxExecutable=firefox.exe" and modified it to "FirefoxExecutable=firefoxde.exe"

I'm aware some programs don't like to be renamed, but I believe it was around 2 days ago that I saw a post that was quite old and it was stated it was possible for Firefox, but I get the error by the launcher, which is not able to find the executable.

Read-only location - Profile folder locked - ESET Browser Protection

I just found the solution to this upsetting problem, thus I am sharing the relevant information with the community.

To solve all these issues, you have to disable ESET Browser Protection for all browsers, which is the second option underneath the Enable Safe Banking & Browsing option in the ESET configuration settings.

ESET - Setup - Advanced Setup - Browser Protection - Safe Banking & Browsing - Enable Safe Banking & Browsing - Browser Protection - Secure All Browsers

Can you please fix the 32-bit and 64-bit issues and options?

32-bit and 64-bit issues and options still states:

The 32-bit version of Firefox in the Firefox directory cannot currently be removed but will in a future release.

But is it still true since 2013's Platform 27.0, which states "This version introduces the option to leave off 32-bit app support in dual architecture apps" and even name checks Firefox?
