Firefox Support Forum

I'm currently using a Windows 10 desktop computer most of the time, but will need to use a Windows 11 laptop for research travel several times over the next several months.

Will it be possible to copy my profile from Win 10 to the Win 11 computer, use the Win 11 computer for a few weeks, and then copy the profile back to the Win 10 computer?

Or is there something different about Firefox working with Win 10 or Win 11 that would keep this from working for me?

(BTW: Using Sync would probably not be feasible.)

Advice will be much appreciated!

I have my saved login and password details from another browser in a CSV and would like to import them to Firefox. I initially did not have the 'Import from a File' option in the drop down menu of the Logins and Passwords tab. After following a guide that instructed to set signon.management.page.fileImport.enabled to true in the about:config page, the option appeared. However, the said option is unresponsive to any clicks. The drop down menu simply closes once the option is selected, without any other reaction.

I'm not sure if this is a related problem but I am also unable to use the Import Wizard that appears on performing Alt+F and choosing 'Import From Another Browser...' The Import Wizard window only appears with a message that says "No programs that contain bookmarks, history or password data could be found."

Funnily enough, the 'Browse..' button for adding images under this support question doesn't work either.

I noticed a glitch with the way my mouse was working in FF, but on Nightly 105 it was fine, so I installed the candidate for 105.1b into my FDE installation folder. Now will this candidate update to the next version of beta automatically, or will I have to install 105.2b myself?

Hey all , i made backup via "export passwords" via password tab and i came back to my pc to and tried to import via csv file but when i pick my csv file nothing happens , any ideas ?

Hello - I've been looking around the Firefox site, and the Internet in general, and so far haven't found out the answer to my question: how do I get Firefox 104 to work on my Linux Mint 18.2 Cinnamon Sonya 32 bit? Specifically what I haven't been able to determine is whether or not I first need to upgrade my Linux, which I suspect. And if so, what's the minimum level of the OS that is required? I may be overlooking the simple answers, but so far I cannot find them. And so far the Firefox website upgrade feature does nothing that I can detect. Thank you for any assistance - Doug.

"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN ```

My wife has an older Mac. About a week ago, a pop-up from Firefox told her to update her program. She loaded in the new one and when she tried to open it she got the message that her computer was too old for the update.

We had to reload the most recent update which had been running on her computer.

Now, none of her bookmarks show up and the bookmark toolbar will not display near the top of the screen as it used to.

None of help items online are of any use because what they say will show up on the screen (such as when you enter "about:profiles") is not what shows up on her screen.

Is there any way to recover her bookmarks, passwords and other saved data, please?

After last update V104.0.2 fire fox will not allow me to access router to change settings message given, unable to connect, can I revert to previous version of firefox as always worked before update

I am not able to download any kind of file, from any kind of website to my disk. I am able to select open on the download dialog, and this will open the file and save it to the temp directory firefox uses for this function, but this does not save the files to disk/the download folder like I want to. I am unable to "Save image as..." as well, since this is considered a download. There is no record of these downloads even being attempted in the download history.

I have recently installed Linux Mint and it came with Firefox out of the box, and I decided to try it out, but I can't, for the life of me find a way to transfer my Opera passwords there. I do have Opera installed right now.

Dear All:

Suddenly FF starts but shows only a new tab without any content. I can fill in a URL but no reaction. Settings doesn't open. Close tab through X Restart FF. no new tab but message: FF is already running but is not responding. The old FF process must be closed to open in a new window. Click to close. a new empty tab pops up without starting FF manually. Close through X Restart brings the same message as above - no window. Have to end FF in Task Manager.

Uninstalled and reinstalled three times - no change.

I'm using Windows 10 and Avast One, Firewall checked - is open for FF.

I appreciate your comments and help. Best wishes Henning

I cannot find this anywhere. As a Topic . I've Reinstalled Firefox several times,and,each time the Browser continues to Import the previous instalations Bookmarks.

Noticed that a small Dialog box pops up stating what is being installed,with 'Importing Previous Bookmarks". Should be an Option on Instalation that handles exactly what is to be described as installed. Supposed there used to be. Since im used to installing w/o 'default settings.

The little check box that denotes 'use old settings,and apps,does nothing.

Have another problem with my Bookmarks. And this is what I need solved Reinstalling Firefox without Importing Previous Bookmarks.

Options for Migrations is not a punn here.

I got a new computer so I created an acct and set all my open tabs and history to sync. It wasn't intuitive to my not techie brain, but found out how to open all the tabs on the new computer. However, they don't open in the same order (makes it almost useless when you have a lot of tabs), and the tabs don't have their associated history.

Is there some way to have Firefox open tabs and history in the same state on the new device?

I kept getting new version is available while I was up to date. This could be due to this:

When I had Firefox in its standard location in C drive, I also installed another copy on my computer's E drive. After a while I uninstalled the E drive version and kept the C drive one.

After that I kept getting a new version is available, but could not be downloaded. I follow the links and find out I do have the latest version. When there is a new version out, in Settings - General - Check for updates I always get the message Firefox is up to date.

I uninstalled Firefox completely, but kept my profile directory contents. After re-installation, I copied contents of my old profile into the new installation default profile.

However, I still get the 'New version is available, but couldn't be downloaded'. The problem is still there.

Somewhere in the files in my profile directory there is still a trace of the E drive installation and the update checking looks at that (I guess ? ) Any suggestions would be appreciated.

I am honestly in chock with Firefox's terrible decision of not providing any option for the user to delete downloaded files.

It is honestly amazing that they came up with such a terrible decision. My downloads folder is a complete mess now and there seems to be no way to fix this.

I don't understand why not just provide an option for the user to only open files. People should be able to choose their settings.

I refereed to this previous post and the solution there didn't work: https://support.mozilla.org/en-US/questions/1370409. By setting browser.download.improvements_to_download_panel to false.

Is there actually no way to only open files now?

If i move the directory to anywhere else it launches In the default location it wont launch - No errors - cannot launch in profile manager mode - cannot launch via cmd - cannot by going to C:\Program Files\Mozilla Firefox\ and launching firefox.exe literally nothing happens

I use both firefox and firefox dev edition. Deleted the dev edition and reinstalled the latest one, now i'm getting the error below on attachment. I did not just uninstall the dev edition but i manually cleaned the directorys: C:\Program Files\Mozilla Firefox Dev Edition C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles

Firefox still works but the new dev edition after fresh install doesn't
