Hi,

I'm working on a Firefox extension where I need to detect print event. I've tried the following approaches:

  • beforeprint – Fires immediately when the print dialog opens (works correctly in Chrome).
  • afterprint – Fires immediately when the dialog closes (works correctly in Chrome).
  • window.focus and visibilitychange – Work inconsistently with noticeable delay, depending on how Firefox handles focus/visibility updates after closing the dialog.

Questions: 1. Is there a reliable way in Firefox to detect print event? 2. Are there any known workarounds or events that could be used for this purpose?

Thanks.

Hello, I have many PCs in my home. Office, Kitchen, Lounge, Bedroom, Man-Cave etc etc etc. I do most of my work on my main PC, but I move around a bit. So I would like to be able to copy My entire Firefox Nightly Build across all my PCs. I have about 16 profiles set up for various jobs. I have seen a few posts that tell me to copy the User/appdata/roaming/firefox folder from one pc to another, but after trying this I ended up with nothing. Is there a simple folder selection I can sync across my network? Thanks Col

[Solved] Unable to Access Firefox Profile Manger Without Opening Firefox

OS: Windows 11 PRO and Windows 11 Home (both 64-bit) Firefox Version: 135.0

Recently set up a computer to use latest version of Firefox. Thought I could just copy and paste the files in the profile folder to the new computer. Found out that didn't work so deleted all the files in the profile folder on the new computer. Copied to a USB stick the Profiles folder on the old computer (according to instructions here: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles). Pasted the folder to the Profiles folder on the new computer.

Attempted to start the Profile Manage without starting Firefox on the new computer in order to create a new profile and point it to the files just copied. This is where the problem occurs!

Regardless of what I type in the "Run" dialog box, Profile Manager will NOT open! After hitting Enter, it opens Firefox! I've tried typing all of the following in the "Run" space: 

firefox.exe -P
firefox.exe -p
firefox.exe -ProfileManager

What am I doing wrong? Any help would certainly be appreciated1

Thanks.
