Firefox Community Forum

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.

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?

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...

Pinterest has been slow to load for the past month. Now it will not load at all. It works fine in safe mode. A fresh install of Firefox did not help anything? I see other folks are having the same problem. Amazon and Facebook are now doing the same thing in Firefox. These 3 programs work without issue in Chrome Brave and Edge. Any one have a fix?

Thanks, Wayne

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...

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?

OS: Windows 11 24H2.

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.

Recovered files and data from a failed M.2 SSD onto a USB. Did a clean install including reinstallation of Firefox on the failed machine. How do I recover the Firefox profile from the recovery USB so it can be transferred onto the restored machine?

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.

I am currently using FF v133.0 and I want to downgrade to v130.0. I tried this once before and could not get the 'Profile' to activate and reinstall all of my settings, bookmarks, add-ons, etc.

Please provide step-by-step instructions for doing this. Any assistance will be greatly appreciated.

I am using Windows 10 64 bit.

Thank you.
