Firefox Community Forum

I've had a problem for a while where Firefox tells me "Firefox is being updated by another instance" and the only way I've been able to get updates is by using the installer.

In my attempts to resolve this, I learned of the `about:profiles`. I have never set up profiles so I figures I should only have the 1 default profile but it turns out I have `default`, `default-release`, default-release-1`, and `default-release-2`.

Of these profiles, the `default-release` is the 1 that has my data while it is `default-release-1` that is able to update.

I would like to make it so that I only have 1 profile that has all of my data AND is able to update.

I already tried removing all the profiles accept the one with my data but that leaves Firefox unable to update. I restored all the profiles I removed and I am back to where I started.

Does anyone have any suggestions?

I have this VPN from Switzerland that is stealing my information I have no idea how it got there on Google. I have tried to remove it but can't figure it out. Can you help me please

I opened Firefox this morning and there were no bookmarks or history. After looking online, I came to the conclusion that I needed to find the places.sqlite and bookmarkbackups files and folders. However, I can't seem to locate either.

I am running Firefox v153.0 (aarch64) on Mac OS v. 26.5.2

I have Time machine backups, but I need help locating the correct files to restore. Thank you.

Using the Firefox 151.0 Mozilla Firefox for Fedora. Updated as of 23 May 2026, I use just a generic FireFox. I don't customize it, I just use it as it comes from the Fedora distribution.

I cannot save images (right click menu "Save Image As"). Nothing happens when that is selected. This worked a couple weeks ago.

Downloads are supposed to go to ~/Downloads. Checking the setting for this, Go to the three-line menu > Settings > General > Files and Applications, under Downloads, the "Save files to" value is set to Downloads, but the Browse button does not work to reset it. Nothing happens when I poke on the button. I can select the text in the box, but I can't change it.

I found the help page for "What to do if you can't download or save files https://support.mozilla.org/en-US/kb/cant-download-or-save-files and went thru every one of the steps there. None of them make any difference.

Strangely enough, there isn't even a "Downloads button" in the top toolbar. If I right click on the top toolbar and select "Customize Toolbar" it shows a downloads icon as already being in the toolbar, but when I click Done, it goes away.

I have always accessed my LinkedIn account on Firefox. Suddenly today, my PW does not work, and my email address for PW reset does not return a PW reset link. Cleared cache without success. I can access LinkedIn on Chrome. Can you suggest what I have done to my Firefox to cause this? Thanks!

I'm using Windows 10 on a PC. Norton Security app is preventing web browsing by Firefox. The message I get is: "We prevented your connection to ful.hartonly.com because it is a dangerous webpage. Threat category: URL:Blacklist" I can still web browse using Google Chrome without any problem. What is ful.hartonly.com and how do I clear it?

I've installed the 10.5.x version of Network on my Ubiquiti Gateway. I now have a problem accessing the gateway. However, this is weird. When on the local network, I can connect directly to it, no problem. Where the problem comes in is when I try to connect to it via unifi.ui.com, the web portal that Unifi Gateways connect to. I've tried a Private Window which is set to not enable any extensions. The results are the same. It will sometimes load part of the page, but never all of it. Before the v10.5.x Network Application update, this was not a problem. I've tried this on both a Windows 10 & Windows 11 computer with the same results. Everything works if I'm not trying to connect via the web portal from the local network. (i.e. If I'm elsewhere or use my cellphone's hot spot, I can connect to my gateway via the web portal without any issues.)

I would blame the Network Application update as the problem if it wasn't for one detail. It does work from the local network if I use MS Edge instead of Firefox. So, I suspect that while there was a change made in this update, there is also something that Firefox is blocking that Edge isn't.

Any ideas?

This problem has never happened before. This happened in the last few minutes. The whole screen suddenly went blank while I was trying to find out today's weather. I am suspicious of malicious interference with my computer. Any help you can give me will be reassuring.

I enjoyed the functionality of the sports widget during the world cup. Are there any plans to make it useful for other sports? is there some kind of API to mess around with to build your own firefox homescreen widgets? I'd love to see MLB schedules/scores/updates populated on the new tab page.

Firefox recently had an update, and now when I am uploading files, I can't double click to upload selected files. I have to first select the file, and then click the open button.

Before the latest Firefox update, I could simply double click on files to upload. This workflow was much faster.

If I go to about:config, and search for: widget.use-xdg-desktop-portal.file-picker, I can change the value from 0 to 2, and then I can upload files by double clicking. However, then Firefox forgets my last upload location, and always opens in the home folder.

If I set it back to 0, it remembers my last upload location, but I can't double click to open files.

My current Firefox version is 152.0.1. Any help would be appreciated. Thanks.
