Firefox Portable

hello everyone,
i'm currently using FirefoxPortable ESR :102.1.0 customized for my application.
This version of Firefox uses the new print preview user interface which has been introduced in version 86.
In order to switch to the classic System Print Preview dialog box , i have added this preference user_pref("print.prefer_system_dialog", true).
However a problem has occured during the print procedure following these steps:
Click on print
Click on Microsoft Print to PDF
Click on PRINT
then Click on Cancel

I've been using Firefox Portable for years and it's been working great. But v111 and v112 both crash on startup. The splash screen shows but Firefox doesn't start.

This might be a difficult matter to agree on, but a lot of people prefer using portable apps on their PCs as local apps. My reason is that it gives me understanding that everything is being saved in one place and not in AppData or elsewhere.

- Install Portable Firefox
- Customize it with stuff
- Update using original Portable installer
- Discover that your customizations were wiped

The problem is, from what I understand, that the installer will wipe the App\Firefox and App\Firefox64 folders. But a lot of customizations rely on additional files located in these folders.

Right now, to update Portable Firefox, I resort to installing a new version into a fresh folder, then copying its contents over my original installation. That way my customizations are preserved.

Hello,
I searched for a answer to my question, but I found not a working solution.
It is possible to start the firefox portable version with a paramter or something else without searching for installed plugins of the Windows operation system. (-no-remote does not work). The best solution would be the use of the .ini file.
This is for me a possibility to have a look on a website with and without plugins.
Thanks for reaction

Good day to all!
I'm interested in the question, what is the reason for the refusal of the x32 version of Firefox ESR?
The browser is already going through hard times, because of the not very clear and not popular decisions of the developers ... But you are there too.
For myself, I found a way out, figured out how to make Firefox ESR Portable x32 from your assembly.
So, here comes the second question. Why are there settings in your assembly that have not been supported by Mozilla for a long time?

Hi,
Using a Yubikey for FIDO U2F has been broken since 110.01 and still broken on 111.0

Works fine in 'Full Fat' Chrome and allegedly works on in 'Full Fat' Firefox (not tested it personally but Yubico Support Team have)

Can fallback to OTP via the Yubikey but FIDO U2F is much more convenient and has worked fine for several years on previous builds of FF Portable.

A fix would be great

Hi

For ages, I'm using Firefox_1.exe, Firefox_2.exe etc. having two separate instances of Firefox available.

But suddenly a few weeks ago, this wouldn't work anymore: Firefox instances are crammed in a single Firefox-Icon on the toolbar even though the exe-files have different names
Well, I had to add "-no-remote" in order to be able to start more than one of them...
Otherwise I haven't changed anything.

After discovering, downloading, and using portable Firefox for a few days, I've discovered an anomaly!!
Using the installed version, whenever I clicked a link external to Firefox (Windows 10 Mail, etc.), it opened in a new Firefox tab.
With the portable version, clicking the link now brings up a new instance of Firefox!
I've made sure all the Tab settings are checked and Firefox is my Default browser!

Any helo would be appreciated!

Hi, since version 109, FF started to have problems with the auto update feature.
If I go to About menu entry, FF tries to check for updates online and, after a while, it replies with this message: "Failed to check for updates".

Strange thing: when I open FF the symbol for a new update availability appears on the command bar option button (a green circle over the three lines). But if I follow the advise, FF offers to download the new version to manually update it.
