Can I copy my profile of one copy of Firefox to another?

I have Firefox 42 perfectly configured on a computer Windows 10. Installation of others is a mess. It's on another computer Windows 10. My user name and directories are identical on each. I don't want to debug ALL the symptoms I have now. It would be wonderful if I could completely uninstall the wrong installation and reinstall Firefox 42 fresh. So until I run it, copy my profile from the good computer on the profile on the newly installed version.

Will this work? Is that all I need to know to achieve this?

(I know that you think that this guy has just need a bit of hand-holding to clear up its problems normally. Believe me, I uninstalled and reinstalled Firefox four times in the last five days. Right now my address bar does not appear, my bookmarks bar is empty, my buttons previous and next are grey and don't function and if I ever fix that I will then find all the problems I've lived with since upgrading to 42.)

Any help will be greatly appreciated.

Copy profile 'good' to a USB "such what."
Then copy the thumb into the profile on the wrong folder.
You can use the Profile Manager to access the 'good' profile.

  • I just transferred my favorites of one copy of Firefox to another and all of my tags disappeared?

    Using Mac OS 10.5.8 and Firefox 16.0.2. I just transferred a bookmarks.html file exported my current installation to a new copy of Firefox 22 on a new computer running OS 10.6.8. Imported bookmarks file into the new FF, moved this import of the 'imported' to the 'Menu' file and used the browser. However, when I went in to bookmark a page, I noticed all my tags and their associated bookmark links had disappeared! Quickly, I assumed that it was a 'tags' file in my original profile that I needed to copy, but I can't find one or all mention of one online. How to copy all my tags and their location of bookmark/url to my new installation?

    When you use the "export" / "import", the tags are not included. Try to use the method of "backup" / "restore".

  • How a Linux user downloads a copy of Firefox to another OS?

  • How can I move the location of the cache of Firefox on another disk to free up space on Cdrive?

    2. Accept the warning message that appears, you will be taken to a list of preferences
    3. Right click somewhere in the list and select "new > String.
    4. For the name of the preference, type browser.cache.disk.parent_directory
    5. For value, type the path to which you want to store the cache
    6. Then find browser.cache.disk.enablepreference, it must be true, if it is not, double-click on it to edit its value

  • Reset used, bad results. ALL copied from old profile to the new file, & FF file now takes 100% of CPU. I can take off safely profile folder?

    Audio delayed or does not stop when you run a video. So I used RESET. Lost bookmarks & homepage & ADBLOCK and who knows what else. So I just copied ALL the files from the old profile on my desk in the new found under troubleshooting. Put everything back, but now FF use 100% CPU when running. I'm sure that I messed up by copying everything but little, I freaked out when I saw that I had lost so much. What can delete the current profile safely folder? (Yes, I feel like a fool and I regret just is go with my screws upward, but I really need help with this).

    I didn't know how to find your answer to what earlier. In the meantime, I used back once again, & found printed the info that I need to copy ONLY the files that I need between previous & new. (Not done yet). But this time, my favorites return. (YAY! "I have a ton of bookmarks). The CPU usage is now reasonable.

    Thank you all for your answers!

  • Can I copy and paste from one project to another?

    I have a scrolling title works very well in a single project and wanted to "simply" copy and paste into another project.  After the copy on the project 1, when I come to 2 project to make the dough, there are nothing to paste.  Is it something with Premiere elements 12, or with my iMac for not keeping that I copied into the memory buffer appropriate?  I found something online which implies there was a software to do this, but I can't believe that this is the only solution.

    I also created a "temporary project" for easier editing with images, transitions and added I want to put into my project "master."  I could create an avi and bring it back on, but I was hoping to get the project finished in a single source.  Any thoughts would be appreciated. Merci.

    The merger of two projects into one is not relevant and overlooks the important of Premiere Elements concepts if all you want to do is to use a title of a project in another.

    There is a simple and effective way to do it. Essentially, you create your title in the Titler to project 1 and then 'save' as a CTR file which can be imported into another project of Premiere Elements through the Add Media/files and folders.

    1. in the project 1, create your title in the Titler. Close to there.

    2. always in 1 project, go to the active project and it highlight / select the thumbnail for the title.

    3. can I go to Menu/export/name of the file and export/save your title as a file .prtl.

    4. If necessary, import the .prtl file project 2... Add media/files and folders/projects active where drag you it to its destination of chronology.

    Conventional techniques to transfer the contents of one Premiere Elements project to another will not apply to your situation somehow.

    Please see the newsletter and let us know how the above worked for you.

    Remember, you don't want to highlight the title in the timeline to get an active file Menu/Export/Title...needs to be the highlight / select the

    title in the active project, then Menu/export/name of the file.
