Firefox Community Forum

I am sitting in hospital with a weird problem. The connection is open and thus not secure. I have successfully connected my 2 android devices, however my Windows Asus laptop is being barred by firefox. I only run firefox. It is a dead end because firefox refuses to allow me to access the net at all. So now I have to get my wife to go and download chrome and see whether that will work. Why can I not override as u understand the risks I also use Norton 360 with its VPN.

Instead of syncing my current settings, sync just overwrote them with an old, outdated copy from another device, completely ruining my addons, bookmarks and various other settings. I managed to restore the bookmarks, but is there really no proper way to undo this or prevent such thing from happening in the first place? Is there no way to control if I want to sync my setting TO the server or FROM the server? How such a vital decision is even made then and why wouldn't there be a way for a user to control that? This is so disappointing :(

I need to recover a `.jsonlz4` file to restore a Firefox session with 8 active instances, as the "Restore Session" feature only opened 5 due to the `browser.sessionstore.max_windows_undo` setting being capped at 5, and the full original `.jsonlz4` file is now missing.

In the`firefox/Crash Reports` directory, there are numerous files I can’t interpret, can I retrieve my session data via telemetry or other methods using this crash information. I’m using Linux Mint with Flatpak Firefox, and I also have crash logs containing a "last crash" text file and a string of numbers, could these be useful for getting back my session?

I'm trying to install Firefox on my work computer (ARM64 version), but when I do I'm getting the crash report window at the end of the installation process (multiple times in a row), if I try to open the browser (only once), and during the uninstallation process (also multiple times in a row). I've tried a clean reinstall multiple times, including deleting the folders from program files, %APPDATA%, and all registry entries I could find (HKEY_CURRENT_USER>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE>>WOW6432Node).

I've contacted IT and they don't seem to think anything pre-installed should be affecting this. I'm unable to get a crash ID as I'm unable to even start the browser - all I get is the Firefox crash reporter, immediately. Is someone able to help me figure out why I can't get this working?

Ran into an interesting bug with Firefox since installing the macOS26 Dev beta. Whenever I use command space to bring up spotlight, Firefox become unresponsive, the beach ball will spin. It will only happen if Firefox is in focus when I use spotlight, and only if I am signed into Firefox sync.

I am not sure of a way to help replicate this issue as it seems to only happen when signed with Sync, but I would be happy to provide additional if I can.

Hello, I just wiped windows and lost my bookmarks, passwords, and the like. I looked into the support options, as well Firefox profiles (about:profiles) but can't seem to get that data back. It's odd to me that it didn't sync because I also wiped windows last month and it recovered all of my data as soon as I signed into my Firefox account,so I was hoping that would happen again.

Any way to get this back?

Thank you.

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

For the past 2 days, Facebook won't load when I try to change my page to another (just switching between accounts). It acts like it is changing or loading, and then I just get nothing. I have done all of the things that are requested from clearing my cache, browsing data, restarting, etc. Nothing is working. I've attached a picture of my screen of I receive when I try to change pages - the big F. LOL Facebook on my phone works fine. I've tried also turning off my VPN and it doesn't load.

I've also had issues with my Xfinity email loading unless I turn off my VPN.

So what is going on?

As the question stated I have navigated to my mozilla profile folder, ( C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\pw1dnvcy.default-release ) but there is no file called persdict.dat. I have ensured all file name extensions are visible, & none are hidden in windows file explorer (Win 10). I am at al loss I cannot figure this out.

Hi!

Previously, all the sites saved in a single container could be accessed via the dropdown arrow to the left of the 'close,' 'minimize,' and 'maximize' buttons. Now, it only shows current tabs, tabs from other devices, close duplicate tabs, and add a tab to one of the containers. But how to open those containers is unclear.

PS I have the latest update 139.0.1

I cannot get past the secure connection failed! I have cleared cookies, cache, etc. I have turned off the firewall, and restarted my computer more times that I can count....

Have an app with a web interface that I used for years, but not with several of the latest versions of FF. Chrome, Edge, and DuckDuckGo all show the page as expected and the page functions properly.

URL: http://127.0.0.1:8384/ Error looks like this:

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:[port number].

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Have tried a large number of things including:

Ping works for ip and hostname, v4 and v6 Confirmed address is accessible through other browsers Disabled extensions Added exceptions in Settings for HTTPS-only mode Various settings in about:config, careful to return them to previous states when they didn't fix the problem Tried Safe Mode (aka Troubleshoot Mode) Refreshed Firefox (as prompted before uninstalling)

My last step is to reinstall, but thought I'd ask here first. Has anyone seen this before?

While I am able to log into my Google account in Chrome, I am unable to do so in Firefox after the latest update. Whenever I try, I am redirected to the attached support page, which asks me to delete cookies and cache contents. Deleting those does not help.

Please help!

Good morning you wonderfull people, I tend to update my computer once every so often. And that time has now come, I have to go through all the setting and extentions on my new system with Firefox along with many other settings for my faverate sorfware. Is there a way to copy all the existing settings to my new set up. Along with tool bar bookmarks that I can't seem to figure out how to export like the normal bookmarks. Kind regards Victor.

There are times that I use the screenshot tool on X.com and the filename it saves to is WAY too long. Sometimes it tries to use the entire content of the post as the filename. I see this effect in the title bar as well. Is there a way to change it so it only uses a date/timestamp and nothing else? Attached is an example of this extremely long naming. Specs: Firefox 139.0.4 (aarch64) Mozilla Firefox for Raspberry Pi OS rasberrypios-1.0 OS: Debian 12 bookworm Kernel: aarch64 Linux 6.12.25+rpt-rpi-2712

Why have ratings of reviews on Amazon disappeared and how do I restore that feature? I do not see a price tag in the upper righthand corner. I'm running Firefox on a PC w/Windows 10.

Just updated to 139.0.1 and got a surprise. My New Tab Favorites Icons now have Push Pins in their upper left corners, leaving less space for the icons, so of course my icons are now smaller than before. Why do the people maintaining the system at Mozilla keep messing with the New Tabs? Last time, they thought they needed to include a large image of the Firefox icon, again shrinking the remaining screen real estate for my icons. That got fixed. Now they decided each favorite icon needs a rather large push pin to indicate that it belongs there. Somebody thought this would be a good idea? Why can't they just leave it alone?

I'm posting two screenshot images of my New Tab screen. You will know which is before and which is after.

Whenever I search something and there is a youtube video included in the search results, all links direct to that video. In the example image it show me hovering over a website link and in the bottom left hand corner it instead tries to open a youtube link at the bottom of the page.
