I-Firefox Community Forum

[edit] I was using my phone to post this question and inadvertently posted it to the android forum. This is a DESKTOP question.

I'm trying to sync my tab groups across my desktop/laptop. I have sync enabled through the settings and I've checked every box, but I don't seem to see an option for syncing tab groups specifically. It syncs all of my bookmarks and active tabs, but the groups seem to be unique to each device. Is this feature available? I might be looking in the wrong spot so if anyone has any insight that would be great! Cheers

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

I found this file on my desktop. File type is Firefox HTML Document. Size 1KB. I've never noticed this before and wonder it I should delete it, move it, or what. Anything to worry about? I haven't opened it.

Thanks for any enlightenment you can offer!

On certain websites , the audio and video still auto play even though the option, "AutoPlay" is blocked for both audio and video.

Please see the attached screenshot which shows that auto play is blocked, it is circled in red. While the video has auto played, circled in orange with a timestamp of 17 seconds being played prior to it being manually stopped.

Please fix this issue.

I have been watching YouTube for years, issue free. This week I was blocked, as my computer may be blocking ads and thus violating You Tubes policy. How can I find and disable ad block programs/ extensions, thus allowing me to get back on You tube. I can recognize an outright program, but do not knew if extensions are in play that are not obvious to me. THANKS

I have 2 instances of Firefox: I use stable for all my professional work, and I use Developer Edition (Aurora Channel) for personal things. The stable branch works fine. In Aurora though, certain key combos will not work. This even persists in troubleshooting (safe) mode.

Specifically, it seems anything using both ctrl+alt will not register alt, only ctrl. alt, alt+shift, and ctrl+shift all seem to work fine, but ctrl+alt and ctrl+alt+shift do not. Again, this works fine in stable, so I am clueless as to why it doesn't work in my other instance.

Another detail is that this happens on multiple websites, not just one. The post prominent one is Google Sheets. In sheets, you can insert the date using `ctrl+;`, the time using `ctrl+shift+;`, and both using `ctrl+alt+shift+;`. Inserting them separately works fine, but both causes only one to insert.

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?

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.

Hello,

I'm a bit out of ideas how I can get Firefox to display the correct characters. For reference: https://learnjapanese.moe/font/

Windows: I only have german and japanese locale installed, i even changed in intl.cpl the language to japanese. I have installed the japanese language pack / fonts and it's showing correctly in any windows editor.

Firefox: Second language set to japanese, disabled all addons, tried it on private mode to no success.

Any ideas how I get the characters to display?

Edit: I made it work by changing in about:config the font.cjk_pref_fallback_order-string to have ja as first.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to nrega.nic.in because this website requires a secure connection.

What can you do about it?

nrega.nic.in has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

Probably nothing, since it’s likely there’s a problem with the site itself.

Hi Please could someone help me re-order my firefox toolbars. Previously I managed to arrange them in the order I prefer, but an update seems to have destroyed the order again, and I can no longer find the web page which explained how to do it. reading from the top, I would like to see: • Title bar • Menu bar • Navigation toolbar • Bookmarks toolbar • Tabs toolbar • Web content area

Instead I have • Title bar • Menu bar • Tabs toolbar • Navigation toolbar • Bookmarks toolbar (I even seem to have lost this now and don't know how to get it back!) • Web content area Thanks for any help that can be provided. Brox

When using the new version of Firefox, I found that bookmarks only appeared in new tabs. Once I opened other web pages, there were no bookmarks above the screen, which made me feel inconvenient. Previously, the new tabs could also be customized, but now they can only be blank or the default pages of Firefox. So, can the new version of Firefox solve these problems? Or which of the older versions of Firefox can still meet my requirements?

Once I visit any web site that uses HTTPS there is approximately a 90% chance it'll take seconds or even minutes to secure the connection. This never happens on other browsers as they load such pages instantaneously.

I already cleaned my data up and removed the extensions, both suspected and innocent bystanders, to no avail.

As stated in the title, I'm using Firefox 139.0.1 x64 on Windows 11 (24H2, build 26100.4061). This started happening after an automatic Firefox update, I never changed anything in my system configuration.

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?

Hello, FF 139.0.4 on MAC Sequoia15.5. Lost ALL references to bookmarks, i.e. Bookmarks Toolbar totally gone. How can/do I restore from .jsonlz4 file in bookmarkbackups. Also, will I be able to salvage my previous profile, presumably containing my older "Tabs on Bottom" work-around? Alternatively, is there a process to restore JUST Firefox from Time Machine? Appreciate any advice.

I have sound in Windows, but YouTube is dead quit. I have tried all that is suggested in Firefox help and some YouTube sites. Nothing worked. I have tried off the computer and restarted, but no change. My system is Windows 11, sound works, and the latest Firefox update installed. Question is this a YouTube tacit to stop NoScript and uBlock?

I keep getting notifications, supposedly from Mozilla and/or Microsoft on lower right of my screen, telling me the system is infected. How do i determine if these messages are valid, or a scam ? Turned computer off and back on--messages keep popping up.

can you give us the option to change the hotkeys/shortcuts please? is it possible for this to be an option for the future, I and I believe a lot of others switching from chrome to firefox would like the accessibility to change it as to what they're used to. Thank you very much for your time.

I'd like to ask about Firefox's behavior and settings. I'm using Firefox with vertical tabs (using an add-on), but it seems to be behaving strangely. The things that have changed since before are: 1. Open from pinned tab 2. Now opens in a new tab → Previously it opened in the same tab 3. Clicking on a newly opened tab opens a new tab again → Previously it would open pinned tabs/same tabs → in a new tab It has changed. I haven't changed any of my Firefox settings. Windows 11 Home 23H2 Firefox version 139.0.4 (64-bit).
