I'm setting up Firefox on a new computer. I haven't done this for a while and the interface has changed, so I'm not sure how it works.

I want to move my Firefox profile to a directory in the Documents library to simplify backup. Following the Mozilla instructions I found, I opened about:profiles and clicked the Create New Profile button. I deleted the contents of the directory that Create New Profile created and copied the contents of the default profile directory to it. The last step is to tell Firefox to use my new profile instead of its default.

But the about:profile page lists three profiles: default-release, default, and my new one. The first two have a Set as default profile button; the last does not. So it appears that I can tell Firefox to use the default-release profile or the default profile, but there's no way I can tell it to use my new profile. I can only Launch profile in new browser -- presumably something I'll have to do every time I run Firefox.

This makes no sense. How can I tell Firefox to use my new profile -- not to launch a new browser with it, but to use it, period? If I can't, why can't I? Every version of Firefox I've ever installed up to now allowed this.

Also, the default-release profile section of about:profiles has the note "This is the profile in use and it cannot be deleted." So it appears that Firefox uses the default-release profile instead of the default profile as its default profile. What is the default-release profile? Why isn't the default profile the default profile?

Since the new "feature" profiles came out, I now always have this "originalprofile" in the browser (in the title bar) and in the Windows taskbar... It's really annoying.... Now my question is, how do I get rid of it again... on 3 more pictures, Firefox language is German...

Greetings...

I work with multiple computers that each use Firefox as their web browser. In each of the Firefox installation are bookmarks, history, and passwords that have been saved over time.

Q: Is there a manual method available that I could use to merge/combine two or more of these bookmarks/history/password "collections" into a single collection, then install the new combined collection on one or more of the multiple computers?

Please advise. Thank you very much! Take care...

I am tired of this bullshit.

So i was using the beta branch of the firefox and beta version stopped working with a site for some time. so i tried to come back to the stable version.

After i do that and fix my config. In every couple of hours there would be a notification window pop up with sound saying this

"firefox this profile was last used with a newer version of this application. Please create a new profile"

So i did create a new profile BUT i copy pasted my own configuration.UI stuff from my old settings from "About:config"

This notification STILL comes up FFS what do i need to do then?

HOW COME MY UI CONFIGURATION TRIGGERS THE DAMN NOTIFICATION?

I will not re-do my fckng UI configuration by hand.

I can not get into my Yahoo Email account. When I log in it says, "Something's gone wrong".

I can get into my Email through a different browser on the same computer. This started last 

Wednesday (01-29) or Thursday (01-30). Help.

Thank you for your time. Tony S.

Hi - I wanted to migrate all my changes made in the flatpak app to the aur version. I noticed the profile content has a different structure in both - aur and flatpak configs. And any attempts to replace profile content with the other resulted in browser ignoring these and initing new config files. Was wondering if my config can be ported over or thats not possible thanks.

Good afternoon. Since recently (probably after the last Firefox update to version 136.0) I have a problem: every time I start Firefox it requires the main password set in the settings. Before this problem did not occur, no settings were changed.

I read the official article on this topic, but the recommendations described there did not help me. I turned off the password, logged out of the browser, turned it back on, logged out again, and nothing. When I turned it back on, still at every startup it asked for the password.

I also noticed that every time I start it up, the loading circle next to the cursor spins, like something is happening. Can you tell me what it could be and how to get rid of this problem?

I have a bunch of profiles set up via "about:profiles". Some of these are associated with different Mozilla accounts, some are not. Today, I wanted to rearrange those profiles to put some older profiles that I do not use as often lower on the page than more recent profiles. I thought I remembered there being an overview text file that included a number for each profile, the folder that profile's information was stored in, etc. When I went looking for that file, I could not find it, so I went looking for help articles and discovered that there is a new profile management tool.

When I tried using the new profile manager via "about:profilemanager", none of my current profiles are visible, so I cannot use that tool to reorder my profiles.

I would be grateful if you could point me to an article explaining how to reorder the profiles in "about:profiles". If that is not possible, I would appreciate a help article explaining the rationale for making these two uses of the word "profile" distinct, the ways in which these profiles are different from each other, and how to transfer settings from the older version to the newer version. I have everything set up just the way I like it within my current profiles and really do not want to have to recreate them from scratch...

When printing history from my bank account there are transactions missing in between pages and extra bank pages. The bank of course says it's the browser. it does it on Edge as well. Please help

Every other day, I open FireFox and may get the following error: XULRunner - This profile was last used with a newer version of this application. Please create a new profile. Also, this error may come up while I already have had FireFox open for a while. Once this error comes up, I check the version, and sometimes the version is older than what it was, meaning, FireFox reverted back to an older version on it's own. I created a new profile, but the error comes back. I removed FireFox and all folders, and the error still comes back. There is nothing I can do to stop the error from showing up again. See attached images. I am on Windows 11 23H2, all windows updates caught up, and the current FireFox browser version is 138.03.

When i upgraded Firefox my old profile doesn't show up now. I found my old profile under about:profiles but when i click on the Launch profile in new browser i get this message, "You've launched an older version of Firefox. Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox" I did create a new profile but how do i get my old saved data, add ons etc to the new profile?

I just set up my Laptop, and now I`m trying to bring my old Profile in, no chance The picture annected is the last, I see, then nothing more. Furthermore: look, please, on the second, no possibility to find my emails and so

Suddenly I cannot access one of my email providers [tutanota.com] because, so its error message says, javascript is not enabled my browser [Firefox is my default browser]. BUT javascript is enabled. [I just checked through taking the steps 1) typing "about:config" in Firefox; 2) clicking "accept risk and proceed"; 3) typing "javaScript" in the select preferences name box; 4) looking at the javascript line for "true" or "false".] Javascript was "true". Help. Please advise.

started receiving this error message while on musify.club. It lets me in, then after a few moments the pop up comes back with same code. after research, it has been deemed that I'm only party affected but I can get in on other devices with no issues from same wifi network. please advise. win 10 pc user. thanks.

Hi,

I am managing some linux servers in schools.

Actualy a lot of users are working with firefox.

Depending on how the user is working with firefox, the profil may reclaims a lot of disk space.

Is there a tool working like :

firefox_cleaning_tool /path_of_profile /options xxx

with some options like : cache / etc...

For exemple : the tool flushes profiles caches files and user have no action to do to continue using firefox as usual

this kind of tool should run every month (ie with crontab)

Is there a way to do that ?

I can manual flush some folders contents but I am afraid to do mistakes.

Thanks for your help

hej, you write oh dear, no print is possible :-((( but you write to me, that I have win10... but it is a new machine with win 11...and firefox does not work, i cant se my mails?!?!!?

We've used Quikbooks for 10 years + on our desktop. After learning the Desktop QB is no longer supported, we attempted to purchase - access, QB online. This required us to return the desktop version, be credited the purchase amount, as we were prohibited use until this Process completed. Now complete! As Techsoup processes have changed, all the back-forth, just not sure. Prior to QB Icloud purchase- need to confirm we didn't already make purchase & guidance re How to access- use online QB version. PLEASE Advise. Thanks
