I have a machine running on CentOS Linux release 7.6.1810 (Core) with kernel Linux 3.10.0-862.14.4.el7.x86_64 .

I want to copy my opera and firefox browser all the settings to a new system as it contains a my old logins etc which i don;t have a recovery for those logins. Since im planning to install the OS again i want to keep all my settings etc same as my present machine . Few question

  • Is it possible to copy use it on a new machine with all the configuration which I'm using .
  • If yes do i need to reinstall the browser again or i can simple launch the already compiled program?

    Your personal settings like passwords, certificates etc. are stored as a profile in the user's home directory, for firefox it is under /home/user/.mozilla/firefox/, see this for more information on what your profile containts, and here's a discription how to save the profile and restore it again. You should definitely install the browser and then use the old profile. Be careful with different versions of firefox. – eblock Mar 26 at 13:39

    And for chrome you can take a look at this. – eblock Mar 26 at 13:39

    Have you tried "Menu > About Opera"? According to google search this shows you the different paths. I don't have an opera browser available right now. – eblock Mar 26 at 13:53

    the folder is located in the /usr/lib64 so there it might contain the profile login etc not sure how to work on it – krushnach Chandra Mar 26 at 13:54

    @krushnachChandra Unless you are running as root (hint: you're not, unless you're crazy) then your Opera profile won't be in /usr/. Try the folder starting with /home/yourusername/ or ~/. – wizzwizz4 Mar 26 at 18:22
