Two Firefox at the same time, (one with images, other without)?

Hi,

Is is possible to use two firefox browsers at the same time, the one with images enabled, the other disabled?

Easiest way on Windows: You'll need 1) the name of the second profile you created, 2) an existing shortcut (already on the desktop, hopefully) to Firefox.

  1. Create a copy of the shortcut, you can right click on the shortcut, and select Send To > Desktop. It will create a nice second copy.
  2. Right click on the copy and go to Properties.
  3. In the "Target" box, you should see something like "C:\Program Files (x86)\Firefox\firefox.exe".
  4. After everything (including any quotes) in the Target box, add -no-remote -P <profile> where <profile> is the name of the profile you created.
  5. For example, if the path to firefox.exe was like I guessed above, it would look like "C:\Program Files (x86)\Firefox\firefox.exe" -no-remote -P my-second-profile

To run the second instance at the same time, just use the new shortcut. The -no-remote flag tells it to start another Firefox process, instead of just opening a new window in the current one.

Never, ever run two separate processes with the same profile. It's so, so bad.

You can set up two profiles (https://support.mozilla.org/kb/Managing-profiles) and then use a command-line option to launch a second instance with the other profile - https://developer.mozilla.org/en/Command_Line_Options#-P_.22profile_name.22

Thanks for the reply.

I did create a new profile and tried to load after I had one default profile firefox browser running, but didn't manage to get it to work with the other profile.

Any clue?

Have you tried it yourself on any computer to assure you that it really works?

Regards.

I run multiple firefox profiles all the time. While the first instance is running, you should be able to `firefox-bin -ProfileManager` ? What happens when you do that?

I'm not sure what you mean? Do you mean when I type in windows (run) 'firefox -profilemanager'? If so, a new firefox browser opens up, with the same profile.

What do you mean with `firefox-bin -ProfileManager`? What is firefox-bin?

on Windows it might be firefox. I think it's case sensitive. did you try 'firefox -ProfileManager' ?

I read it's on Linux it's case sensitive from the link you pasted. Not in Windows. But I tried also what you wrote, the same thing happened: a new firefox instance pops up.

What's going on?

you might also need -no-remote flag.
