Is there a way to backup a profile?

Hi,

I used to be able to copy all the files and folders from: C:\Users\Admin\AppData\Roaming\Mozilla\Firefox\Profiles\a4tgn35f.default-1533640645510 to another disk location, except for few files getting 'Destination Path Too Long', without any problems.

The problem lies mainly with the JSON files.

I do this copy primarily because I want my Firefox profile on laptop to match my desktop.

Before copying the contents of my Firefox profile to my laptop I recall also being able to remove all files and folder in my laptops Firefox profile. - But it is not really necessary to remove the Firefox profile files on my laptop before copying to it.

But now I have problems both copying and removing Firefox profiles - but for now it's only about copying the Firefox profile - not removing ....

I have added some images showing what happens when trying to copy a Firefox profile.

Please HELP.

Best regards, Einar

Hi!

I am not sure how to address this. I like to have my pinned tabs always in view whenever possible. So when I click on another tab outside the tab, I'll utilize that and then go back home. While in other tabs, I may utilize the extension tab manager plus for Firefox. The last few days I'll click on a tab on need. It opens the page, but does not show the tab at the top of the screen. What is happening and how do I fix this?

Thanks.

Running Firefox 141.0.2 on Mac Sequoia 15.6.

I have frequently used firefox to reach this local server until today. The server itself currently responds to pings, traceroute works. I can ssh to the server. I can access an SMB share on the server. All of these were tested after I ran across this issue. The server doesn't support HTTPS.

Today when I attempted to reach the server in Firefox. This time I got a popup (from Firefox, I presume) asking if I wanted to add this server to some sort of list. As I am still largely human, I didn't really read the popup, and just selected "No". And now I can't reach the server (from Firefox, that is).

So, how do add this server to Firefox's whatever list? The "Server not found" message is, as always, not even slightly helpful.

Thanks in advance.

Any Ideas what is going on? About July 21st, 2025 I started noticing with a couple of browser tabs open, a new tab opens autonomously and flitters in the new tab name area, what "looks like a TagID", then closes by itself. I define "looks like a TagID" as something that looks like a tag at end of article link in popular newsletters I see, and appears in the url bar of the linked article.

The occurrence of the new tab happens when I open the browser, within 1 minute and occurs randomly during the session, perhaps every 20 minutes.

My first suspect/assumption is I am always signed into Mozilla when I open Firefox 141.0 (64 bit), processing an update now, Aug 5 2025. I have subscriptions to VPN and Monitor and I have sync (passwords and bookmarks) with my mobile instance of Android Samsung Galaxy phone.

My Desktop is set up as Windows 11 pro with one employer InTune acount for Microsoft but I limit that work to Edge browser.

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.

About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.

Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.

Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!

The bookmarks and folders that I delete keep on returning. I have tried everything I know:

• disabled sync,
• deleted backups...
• deleted Firefox from my other devices

everything. But the deleted bookmarks and folders keep returning in my Bookmarks menu and in my Bookmarks Toolbar. Sometimes I get into "Manage Bookmarks" and I see the deleted folders reapper just a few seconds after I have deleted them. Any help would be greatly appreciated. I am at the point that that the next thing to try would be to switch to another browser

Trying to load https://www.fire.ca.gov/incidents and it does NOT load completely, which it did before all of the upgrades... have to use chrome to view the site.

I just installed the latest Firefox update and all my bookmarks and passwords have disappeared. Can someone please tell me where there would be stored so that I can re-install them. This hasn't happened with previous updates. I hope I have chose the best topic for my question.

The Atlassian Confluence "Audio Briefings" icon is consistently greyed out using the Firefox web browser (my browser of choice). How can this be enabled? This is not an issue using the Chrome and Safari web browsers on the same content. I have verified Autoplay, Microphone and Speaker settings and ensured the domain has been added to the list of exceptions to the default (which is more restrictive). Hardware and WebGL are both enabled as well. I would think Firefox would want to ensure the browser is compatible with major business applications such as those by Atlassian.

Hi, All of a sudden, bookmarks disappeared. There was a Firefox update a few days ago which fixed the problem but....it's back again, no bookmarks. My security systems have not changed whatsoever (Windows and McAfee) plus I use Ccleaner to tidy up my system at close of play. Will the bookmark system ever be fixed please?

Hello,

I’m experiencing an issue where I cannot use ChatGPT-5 in Firefox. When I log in and try to select or use GPT-5, nothing loads or functions properly. Other models like GPT-3.5 work normally, but GPT-5 does not respond.

I’ve already tried refreshing the page, clearing cache and cookies, and even disabling extensions — but the problem persists. Could this be a compatibility issue with Firefox? Any advice or support would be appreciated.

Thank you in advance for your help!

I updated my mac to Sequoia 15.6 and after reopening my macbook all windows of firefox are invisible on screen. If i checvk which windows are still open, they all are but I can't see them nowhere. How to proceed to see them?

Sync works fine between my Android phone and my devices, in that I can see open tabs on the phone from both devices. But what does not work is sync between the laptop and desktop. They are both listed as connected devices along with the phone, both are signed in, both synch with the phone but neither will sync with the other, so I can't see the open tabs on either device. Is this an issue or is it by design? Thank you.
