Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

I have Norton 360. I just reinstalled a brother printer and now I get the "Your browser is being managed by your organization". While I sync with my laptop, as others have said, I'm not an organization. There is an Enterprise policy .

Active Policy Name Policy Value ExtensionSettings {"firefoxhpsureclicksecurebrowsing@bromium.com":{"installation_mode":"blocked"},"firefoxhpwolfsecurityextension@bromium.com":{"install_url":"https://addons.bromium-online.com/wsx.xpi","installation_mode":"normal_installed"}}

I can't store or edit any bookmarks. How do I correct this? I need answers in very simple terms as I am very much a layman with computers. Thank You!

hi, I love supporting this independent browser - I know its not perfect but it does a great job of doing most things well.

However, and there is a big but. I can be in the middle of an investigation that requires sharing data to a new tab - on opening the tab I'm blocked from going further as Firefox needs to do an update! This is really infuriating. No update can be SO urgent that you stop me using the browser. This is the Microsoft mentality, and its wrong. Can you please investigate NOT forcing users to update their browser during session.

I teach an online Adobe Illustrator Course. Students upload (.ai) Adobe Illustrator files. Not .svg or .pdf. But Firefox changes the (.ai) extension to (.pdf) upon downloading. This is HIGHLY irritating. Firefox, in prior versions, did not do this. In Firefox settings for Applications, there isn't a choice for .ai (Adobe Illustrator) files. I 'assume' that when AI (artificial intelligence) became available is when Firefox began automatically changing (.ai) files to (.pdf). PLEASE SOLVE this as I have to manually change the (.pdf) extension BACK to (.ai) HUNDREDS of times a day.

For years, my Dell Latitude (Windows) laptop and devices connected to it via Bluetooth coexisted well. For this same time, I have used Firefox (latest version) only. The laptop connected to whatever Bluetooth device I was using and it worked when i used Firefox.

This changed about three months ago. According to my tech repairman, what has happened is that, although the (Windows) laptop connects with the Bluetooth devices, Firefox for some reason stopped allowing the Bluetooth signal to go through.

There has never been any notification from Firefox, never has been a way to edit a setting to allow Bluetooth to work, and no option(s) ever offered to allow Bluetooth to work.

Does anyone have a suggestion about fixing this; other than the obvious – use a different browser?

Thanks.

Hi,

I just updated to the latest version of Mozilla FireFox and my bookmarks dissappeard.

All are gone, I wonder how I can get them back?

Many thanks,

I used to have about 40 quick links, or bookmarks on my home page. I had pinned several. Others appeared according to how often I used them. The latest update deleted all but 3. I am very unhappy. How can I get rid of this update and bring back my quick links? I guess I will have to go back to Brave.

Hi All,

I would like to remove the first item from the Tab Context Menu, which is "Add Tab to New Group", and simply have "Reload Tab" as the first menu item.

I was using this code, which worked in FF 145, until the latest update (FF 147)...

#context_openANewTab,
#context_moveTabToNewGroup,
#context_moveTabToGroup,
#context_ungroupTab + menuseparator {
   display: none !important;
}

However, now there is an extra separator line at the top of the menu (see attached images).

This code also removes the top menu item, but still leaves the separator line on top:

#tabContextMenu #context_moveTabToNewGroup {
  display: none !important;
}

Is there a way to remove the first menu item without adding the separator line?

Thanks!

After updating to Firefox 147.0.3 all of my browser history (along with open tabs at the time of updating) is lost. I just updated to Windows 11 workstations (plus a couple of older Windows 10 workstations) to the current (Feb 2026) updates too. However the history data was lost before the Windows updates. I noticed that with the previous update of Firefox that saved login information was also lost. Who is doing your program updates, a chimp?

In the past when an update was done the browser would open back up with all of the previous versions session tabs in tact. But not now.

I've lost several tabs of research that was being done. Based on what has been happening, I will HAVE to change to some other browser. This is a shame as I've been a loyal Firefox user since day one. Good bye Mozilla and Firefox.

Firefox updated automatically overnight, all bookmarks vanished. Toolbar bookmarks, gone. History information disappeared two weeks ago. Library box is now gone, too! Windows 11. Firefox version 147.0.3 64-bit

The same thing happens on my two Dell laptops (Inspiron and Latitude), and a Hyper-V VM (on my desktop PC). They all run Bazzite Linux 6.17.7-ba25.fc43.x86_64.

A video may play for a second or two, and then it's either a black screen, or an error message of "The content doesn't seem to be working."

On the same two laptops and VM, the Chromium Browser, and LibreWolf (a fork of Firefox?), have no issues playing the same videos.

Firefox version on all three systems is 147.0.3.

Any help/guidance welcome with thanks.

When backing up bookmarks to HTML - HTML Back-Up does not include the TOOLBAR Bookmarks. Please advise how to include the toolbar bookmarks in HTML format. Thank you.

This feature/option is not working. I close with multiple tabs open, and restart and only the generic search/home page is there. It is tedious to have to reopen if many tabs have been used.

When Firefox updated to 147.0.3, it shredded Quick Dial and I am using the latest version.. Less than half of my tabs still exist, and many of the "everyday" tabs - banking, utilities, online purchasing, etc, - are simply gone. Unless there is a solution, and I have contacted the developer with no success, I will no longer be a Firefox user. Beyond this issue, Firefox has been increasing difficult to use for purchases (big examples, Rock Auto, PayPal) and have had to switch browsers too many times to complete purchases DESPITE making exceptions for these websites in Settings. This situation is the proverbial "last straw". Solution or I'm out. Screenshot attached would have originally shown A FULL PAGE OF TABS.

This problem has been covered in this forum before. However, the various solutions have not worked for me because it seems my backup previous.jsonlz4 was corrupted. I did exit Firefox normally, but I am not sure because I have been using multiple different browsers in recent months.

This is what happened this morning: my Firefox on Mac OSX was closed normally, and I rebooted the MacBook. Afterwards, I could not restore old tabs because "Recently Closed Tabs" and "Recently Closed Windows" are greyed out.

I tried copying recovery.jsonlz4 from the last folder and putting it into the main folder as sessionstore.jsonlz4, then reopening Firefox. Still have no restored tabs. Here was the surprise, which I do not know how to interpret.

I just checked some files and found this error message in sessionrestore-logs folder:

1770888233416 SessionStore ERROR SessionSaver write() rejected with error: Error: SessionFile is closed(resource:///modules/sessionstore/SessionFile.sys.mjs:424:29) JS Stack trace: write@SessionFile.sys.mjs:424:29 write@SessionFile.sys.mjs:47:32 _writeState@SessionSaver.sys.mjs:375:29 _saveState@SessionSaver.sys.mjs:308:17 _saveStateAsync@SessionSaver.sys.mjs:354:10 saveStateAsyncWhenIdle@SessionSaver.sys.mjs:194:14 requestIdleCallback/<@Timer.sys.mjs:180:15 observe@AsyncShutdown.sys.mjs:570:17
