Firefox Portable

Cannot make FirefoxDE to run when modifying the executable & ini

Submitted by ANONS on October 23, 2025 - 4:51pm

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?

Firefox Portable no longer starts.

I have been using Firefox Portable Version 142.0.1 for a while. Now it will not start.

The first thing I noticed was that my backup operation was having problems because it was saving information into the profile/datareporting/archive directory despite data reporting being turned off. Further complicating thing is that the archive directories and files require odd administrator access which foiled the backup and would not allow me to delete them.

Whether it is related or not, now it simply won't start up.
