Go to the old computer. Copy the old profile to a thumb drive. Put the thumb into the new computer. Then Copy the files to the new profile.

where can I find my profile? and what is a thumb drive?

A thumb drive is an external hard drive about the size of your thumb. By using this, you can quickly copy / move file one system to another.

On my Windows 7 computer, the Firefox profile is here; C:\Users\==<user-name>==\AppData\Roaming\Mozilla\Firefox\Profiles

Using the Firefox browser; Type about:support in the address bar and press enter.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

ik heb al deze stappen gedaan, de pc opnieuw opgestart maar zie nog niet mijn oude favorieten staan jammer genoeg.

Warning ! ! Only Copy the files you are told. We will avoid anything that might cause you problems. Here is the list of files;

cookies: cookies.sqlite Do not bother. Cookies will be created when you return to the website. However, you will have to log in everywhere. And you may lose any settings that websites store on your computer.

extensions(add-ons, themes): it would be better to download them fresh. +++++++++++++++++++++++++++++++++++++++++++++++++ key3.db and logins.json : These are the Password files. Copy Both !

persdict.dat : custom dictionary – words you added to the dictionary

mimeTypes.rdf : What to do with what type of file.

places.sqlite : History and Bookmarks.

prefs.js : Your settings. Note, If you were having problems, this could be contaminated.

cert8.db and possibly cert_override.txt : Stores all your security certificate settings and any SSL certificates you have imported into Firefox. If removed, the file will be replaced.

search.json.mozlz4 file stores the user-installed search engines that are available in the Firefox v45+

search.sqlite file and searchplugins folder store the search engines that are available in the Firefox Search bar. +++++++++++++++++++++++++++++++++++++++++++++++++ Copy these files from the old to the new. You will get a message that the files already exist. Choose to over-write for each file.
