Theoretically yes if they run Firefox will have to create a new profile for self:

• https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer
• https://support.mozilla.org/en-US/kb/import-bookmarks-html-file
• https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

If you are in the USA expect your phone, USB to be looked at if they so choose to do so especially on return. No idea about EU. You can just get a free online email account and export bookmarks and email them to your self than access anywhere, also email link for portable app. Whatever your good with as is your data.

Please let us know if this solved your issue or if need further assistance.

Ignore portable apps, no mac version

Thank you. Since you wrote that "in theory" it will work, all I can do is try.

About e-mailing the profile to myself, the total size of the files (without counting subfolders) of the Profile folder is 84MB. Not an option.

Thanks again for your help.

Dropbox.com, default is 100 I think. Or if just need bookmarks only, I email mine all the time, they from 1995. I say in theory as I never have done it. I do not know what a Mac does with files. I would think they go across.

In principle you can copy a full profile folder to an USB stick and transfer this profile folder. Make sure to include profiles.ini and keep in mind that the folder structure may differ. There may be files like prefs.js that contain absolute file paths to files and printers, so you can check this file of file paths.

Note that you only need the main profile folder in "AppData\Roaming" on Windows.

Firefox uses two locations for the Firefox profile folder, so make sure to look in the correct location. Location used for the main profile that keeps your personal data in "AppData\Roaming" (Root Directory on about:profiles).

• C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
• ~/Library/Application Support/Firefox/Profiles/<profile>/

Location used for the disk cache and other temporary files in "AppData\Local" (Local Directory on about:profiles).

• C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\<profile>\
• ~/Library/Caches/Firefox/Profiles/

You only need the former in AppData\Roaming and not the latter in AppData\Local.

You can use buttons on the about:profiles page to go to a profile folder.

Thank you both for your help.
