Firefox Community Forum

Over the past 3-4 weeks, everytime Windows pushes an update, it switches my default browser (Firefox) to Microsoft Edge.

I have spoken, at length, with Microsoft about why this is happening and how to prevent it. Ultimately, their final response is that Microsoft is going to switch my default browser to Edge with every update.

First, I´d like help to find a way to block this from happening without having to just stop all Windows updates.

Second, Years ago, Microsoft lost a lawsuit because of the monopoly when they forced everyone to use their Internet Explorer, but now, it seems that they´ve just decided to ignore that ruling. Can anyone tell me which EU organization I should file a complaint with?

Hi, I’m having trouble keeping my bookmarks in sync between my Windows laptop and Android phone using Firefox Sync.

I’m logged into the same Firefox account on both devices, and Sync is turned on. However, new bookmarks I add on one device don’t appear on the other.

I’ve already tried:

Signing out and back into my Firefox Account

Forcing a manual sync

Checking that both devices have the latest Firefox version

Is there a way to manually trigger a full re-sync or reset the Sync database without losing data? Thanks in advance! 🙏

Hi,

I have noticed that quite often web sites are not opening the first time and FF reports broken connection. Refreshing or trying the second time helps - sites open very quickly.

What may be the problem?

I am using the most recent version on Windows 11 24H2. This behavior appeared about a week ago. I have reinstalled FF but it didn't improve anything.

Thanks!

I have been a long time user of FF and have been puzzled by it's recent failure (to both start, and subsequently re-install) For the last 18 months I have been running Win 12 without problems. That is until last week, when I can only assume the Tuesday udates ( MS) has created havoc. I would appreciate any assistance as I am not fond of MS Edge, or Google Chrome. Dave Hickman.

After a re-start, my Firefox browser on a Dell laptop lost all history and has since also not been collecting websites visited. When opening a new tab, the shortcuts and recently visited websites are also gone and no longer being collected. My CCleaner recently updated itself to a new version but I unchecked the delete history for Firefox (which treacherously is clicked by default - I fell into that trap before). Happy to blame the new CCleaner but that would not explain why history is not being collected now - to me the fault seems to lie with Firefox instead. Another possibility that went through my mind: Is Microsoft sabotaging users of Windows 11 to force them to buy new? PS: Under "Privacy", "History", the setting is "Firefox will remember history", as it always has been and should be. But it has forgotten all previous history and it is no longer collecting any new history either!

Hi All,

I was using the following CSS to hide the navigation images and show only text labels on the context menu for the Back, Forward, Reload and Bookmark Page menu options...

/* Content Area Context Menu - Navigation Vertical Text */
#context-navigation,
#context-navigation > menuitem{
  flex-direction: column !important;
}

/* hide images */
#context-back image, #context-forward image,
#context-reload image, #context-stop image,
#context-bookmarkpage image{
   display: none !important;
}

/* show text labels */
#context-back:after, #context-forward:after,
#context-reload:after, #context-stop:after,
#context-bookmarkpage:after{
   content: attr(aria-label) !important;
   margin-inline-start: -19px !important; /* this pushes navigation text items to left, aligned with other menu items below */
}

It worked up until a couple of versions ago, but something has changed, and my CSS is now broken, and those navigation icons are back.

My context menu now looks like the attached image below.

Any help with showing only text labels on this menu is appreciated.

Thanks.

Hi, I've been using tab groups for a while and i had some pretty important tabs save there. I wanted to know if they get deleted after a while or not, Because all of mine suddenly disappeared. And also is there anyway to get them back?

The issue started about one week ago (today is 10/11/25). When I wanted to print while in Firefox browser, the print never executed. Instead the screen froze as did the browser. I had to do some experimenting to use my pointer and open a different browser. Yes - besides the pointer being frozen (all that showed was an hourglass) my keyboard was also frozen. When I finally opened a different browser and printed the same item, no problem. I had to close Firefox to be able to fully use my laptop again. I searched the solutions and none had an effect. Firefox would still freeze/hang/lock up when trying to print. The browser is up to date.

In one of my Firefox installs, the Profiler automatically starts recording every time I open Firefox. There's a button on the right that looks like a speedometer and it is blue until I tell it to stop. Then it is taskbar button color.

Profiler instructions at https://profiler.firefox.com/docs/#/./guide-removing-profiler say to simply drag this button off the toolbar and it will stop record. On restart, it's back on the toolbar, and it's recording.

I have tried refreshing Firefox. Doesn't help.

I have tried uninstalling and reinstalling Firefox, and then setting up a new profile. Doesn't help.

I have tried deleting prefs.js. Doesn't help.

I have tried opening up the developer console, opening settings, and unchecking "performance." Doesn't help.

I searched the registry and found a key called MOZ_ENABLE_PROFILER (iirc, something like that). I set it to zero. Doesn't help. I then deleted the key entirely. Doesn't help.

How do I get rid of this thing? It must be a registry setting of some kind, as it appears in whatever Windows account I open Firefox from, but I can't find it. It is deeply frustrating as the computer it is happening on is my oldest computer, and I don't want a recorder running in addition to Firefox.

Hello, I recently purchased and started using the Hyperx Cloud 3 wired headphones. When I watch a YouTube video or shorts with these headphones, if I skip forward a few times or scroll to watch a new short, a loud popping noise occurs in the headphones. I turn the volume up and down, and it fixes it. Interestingly, this doesn't happen in other browsers, only in Firefox. This is very interesting, and I can't figure out why. I wanted to share this with you because I love Firefox.

NOTE: There's no problem with the headphones; they work perfectly. This is an issue only in Firefox.

The newly added PWA support is neat and was much needed. However there is an issue with the PWA icons under Windows, in the Start menu. In the all programs tab the icons are correctly the icons of their respective websites, but if the icon is pinned as a tile it switches to the default firefox icon making it hard to tell them apart at the first glance. The issue is present under Windows 10 and also Windows 11 How to recreate: Win10: -add a tab to the taskbar as a PWA -open Start menu -pin the PWA Win11: -install ExplorerPatcher and change the useless clunky win11 Start to the almighty and productive win10 Start -add a tab to the taskbar as a PWA -open Start menu -pin the PWA

Is there any way to fix the icons of pinned PWAs?

I'm having trouble installing Norton Password Manager, I keep getting a corrupt file, won't install, so I am running through the checklist of possible fixes.

The one I am up to is this :-

Refresh Firefox Click the menu button (≡). Select Help, then choose More troubleshooting information. Click the Refresh Firefox… button on the right side of the page. In the confirmation window that appears, click Refresh Firefox. Firefox will close and restart. When it finishes, a window will show the data that was imported. Click Finish. Choose whether to restore your previous windows and tabs, then click Let’s go!.

I cannot find the "Refresh"

I've run Troubleshoot Mode

I have cleared the startup cache, problem not fixed.

On Sunday October 5, 2025 I began experiencing an issue with gocomics.com. I thought it was a temporary one that would resolve itself. Monday morning it was still happening. I contacted GC thinking the issue was on their end. They were unable to replicate it. They asked me to try to go to the site using the private window on FF. I was able to access it just fine. Therefore, we know it is not GC. I was also able to get to their page on Chrome.

I tried again on Tuesday. Same issues. I had already read on some forums where others were getting the same loop that I am: https://amub2c.b2clogin.com/amub2c.onmicrosoft.com/B2C_1A_GC_SIGNINSIGNOUT_POLICIES/oauth2/v2.0/logout?post_logout_redirect_uri=https://www.gocomics.com

It was suggested to try refreshing FF. I did that. Didn’t work. Gave up again for the day.

This morning, I tried uninstalling FF. Didn’t work. What else is there left for me to try?

Hey folks, I recently installed a new NVME, clean Windows install, clean Firefox install. Recently I've had seemingly random crashes on tabs, happened a lot with YouTube and seems to happen fairly consistently if I go to my watch history. Other sites seem okay, everything else seems to be working fine, checked my drive, my RAM. This Firefox install is using my Mozilla account for passwords and themes. Included a recent crash report if that helps. Thanks if any of y'all can help
