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!

Every time I try to use my camera or microphone on some websites from on firefox it says can't detect camera or microphone? It doesn't show up with the 'allow this website to access your camera/ microphone' pop up it does with other websites. I went into permissions and manually changed it myself and it said it still couldn't detect the camera/ microphone

Firefox stores certain temporary data in a startup cache to improve startup speed. Clearing the startup cache and then restarting Firefox can sometimes fix various issues, such as mixed languages in the user interface after an update. This will not change your profile data or add-ons.

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.

I used to be able to have all sorts of tabs open for an entire month. Now, I can't keep them open even for a day. It seems to be a problem selective to Youtube (other tabs like Yahoo Mail still work), leaving my Alienware 15R4 laptop fans running really loudly for a few days now, since updates ran (not sure if that's related), and leaving me having to shut down and reboot the browser, daily, instead of once or twice a month. Is there anyone working on getting us back the old Youtube, or replacing Youtube with something like what it used to be? I am running adblock plus and uBlock Origin, should probably turn them off to see if they're related to the problem, huh? I'd hate to start having to use a different browser.

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,

When the Global Privacy Control request is checked (https://support.mozilla.org/en-US/kb/global-privacy-control?as=u&utm_source=inproduct) a persistent bubble appears at the bottom of the page indicating the request has been accepted. The bubble is annoying. Is there a way to continue to use this feature without the bubble appearing?

I have configured Firefox to use a proxy, and I stored the credentials in the password manager. However, every time I open Firefox, it asks me to enter the credentials again.

How can I store the proxy credentials persistently?

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!

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.

Why is firefox blocking the paypal popup??? I've tried all the solutions to get it to work, but it still does not work.

Went into Settings/Privacy & Security/Permissions, Block pop-ups and third-party redirects is selected, but I've added http://paypal.com and https://paypal.com to the exceptions

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

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.
