A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

my pc had friend so when i got a new one i lost all of my firefox data, how can i get all of it back so i was forced to start all over, i lost all my, bookmarks, tabs, history and saved passwords

Hello team,

I'm not sure what happened, but I was not able to open Firefox after restarting my PC. I currently run Windows 11 on a fully upgraded rig.

Up until today, I have been trouble free. Error 1: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I tried several options - and have been googling/trying several steps for a couple of hours (after each step, I restarted the PC):

1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Attempted to use Command Lines to open Firefox https://wiki.mozilla.org/Firefox/CommandLineOptions 3. Opened Profile Manager and attempted to create a new profile - when I did this the new profile would not display in the Profile Manager, but it would display in the Profiles folder under Appdata [I tried this multiple times] 4. Deleted the profiles.ini file

After deleting the .ini file Error 2: "Your Firefox profile cannot be loaded. It may be missing or inaccessible." 1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Opened Profile Manager and attempted to create a new profile. After following the Profile Wizard, another error pops up: "An unexpected error has prevented your changes from being saved."

I am completely stumped. I hope you can help, Sean

Today, my daughter received a notification that the Dragon Professional Web Extension has been disabled (see attached image). This was done because the extension supposedly executes remote code and collects user data.

My daughter, a mathematics professor, has very limited use of her hands. She is dependent upon Dragon to do her job. This is not something she just likes - she has a disability and she NEEDS it. Disabling this extension will make her job significantly more difficult, and there are capabilities that the extension provides that she may not be able to duplicate with workarounds.

PLEASE, make the extension useable again. This is an accessibility issue for disabled people - it's not just a fun addition to the browser. If necessary, add some sort of acknowledgement checkbox so that she can acknowledge that she is taking some risks in using it.

One other thing. Disabling this extension with no advance warning was a disservice to all disabled people who depend on it. Had this occurred in the middle of a semester, the effect could have been catastrophic. As it is, she may need to spend the rest of the summer trying to figure out how to do her job without it. You have really, really done an extreme disservice here.

On Mac OS 14.4 Firefox hangs on launch and crashes, requiring "Force Quit" when I try to Refresh or Troubleshoot. Uninstalled and reinstalled multiple times, and restarted computer several times. Have spent several hours trying multiple community suggestions to now avail.

I am not a programmer, but am able to follow instructions. I clearly need someone to hold my hand and walk me through the solution. (I even checked out the Kaspersky suggestion, but cannot install it because Firefox cannot connect to the Internet.)

I have downloaded and saved "Raw Data.docx" and "Application Basics tex.docx" from one of the crash reports.

P.S. On this question form Firefox guessed that my operation system was Mac OS x 10_15_7, but it is 14.4

Hi All, Apologies if I've missed something, but I can't find an answer anywhere. I've got a fresh install of Firefox version 133 running on Windows 10, and I can't seem to install any add-ons. When I click the install button from the add-on's page, it just sits there with the loading animation and seemingly does nothing for several minutes. Attempting to right-click on the download button, "save link as", and hitting "install add-on from file" using that saved link as another user suggested from a similar problem does nothing at all; there's no feedback whatsoever. The add-on I've been trying to install is U-Block Origin, but I've tried this with other add-ons to the same results. The only other thing I've tried is installing one of the recommended add-ons from the add-on page directly, Privacy Badger specifically. This causes an actual window to pop up telling me Firefox is verifying the add-on, but nothing happens past this point. It just sits there, eternally attempting to verify the add-on with no progress ever made, and no error message ever spitting out. I haven't found anyone else with this exact problem. Hopefully I'm missing something obvious and I can feel really silly about the whole thing soon. Thanks much!

All the Best, G.B.Bari

As of last week, FF works for a few minutes on startup, but then when you open a new tab and try to go to a site you just get the dancing period, nothing opens. Already open tabs with sites generally still work, but sometimes crash the tabs after a bit. We've tried starting without extensions, uninstalling and reinstalling FF, changing the profile, logging in the PC (Win 10, up to date) with a different login, running SFC and DISM on the PC, and just about everything else.

Opening the FF console shows this message when the tab just rocks the period:

WindowsJumpLists: Failed to fetch favicon for https://online.adp.com/signin/v1/?APPID=WFNPortal&productId=80e309c3-7085-bae1-e053-3505430b5495&returnURL=https://workforcenow.adp.com/&callingAppId=WFN&TARGET=-SM-https://workforcenow.adp.com/theme/admin.html NS_ERROR_FAILURE: WindowsJumpLists.sys.mjs:257:29

Edge works perfectly (and unfortunately, I'm having to use Edge to enter this ticket.). Other applications don't have any issues. I'm not having this issue on 2 other similar PCs I have that run FF, only this one.

Any ideas of what might be the issue with FF on this PC? Thanks, Alex

A while ago I made a Firefox account with my Yahoo email address as the primary email, and my Outlook email address as the secondary email. Eventually I realized that I didn't need my Yahoo email account anymore, so I deleted it, forgetting that it was being used as the primary email for my Firefox account. Now I can't remove my Outlook email from my Firefox account without verifying my Yahoo email account, and I can't even delete the Firefox account since it was made under the Yahoo email account as a primary email address.

Now I can't use my Outlook email address to create a new Firefox account either.

Hi

I've just booted my machine and opened Firefox, only to be presented with a completely fresh install.

All my settings, bookmarks and history gone. It was fine yesterday when I closed it and powered down.

I'm running Kubuntu, I've checked the .mozilla folder and nothing...it's like my profile has just been overwritten.

Not happy at all, I'm starting to dislike Firefox.

Can anyone offer any help or advice please?

Thanks in advance.

Hi,

When I got up this morning, I receved an email that a new device was logged in to my firefox account before an hour or so.

All my passwords are synced to firefox account. I am afraid and want to know what all information is stolen. I immediately removed old devices from accounts page under connected services. However, I see peculiar - 'unknown' device which I can not sign out.

I am trying to move one tab from one window to another. It says I should be able to move it just by clicking on the tab and dragging it to the window I want to move it to. But, when I try this nothing happens, it won't move.

Want can I do to resolve this?

Thanks

I note that there are 399 posts referring to this problem. The problem has existed on my PC for about 4-5 months.. DELL support has checked my computer, we have cleared cache and browser and tweaked other controls but nothing helps. I have no problem using Google Chrome. If so may people are having the same problem surely Firefox should be making an effort to fix the bug??!! Just drafted a reply to you from Firefox site but as frequently happens message appeared -

 Something about oops and an error message. When it occurs drafts do not save and messages do not transmit.

Sorry the screen print will not copy across.

I use Firefox as my main browser and it is inconvenient to have to swap between Firefox and Chrome

Can Firefox please fix this problem?

thank you mlmg

The Firefox 'Downloads, Save Files To.." location appears to be disconnected from reality. If I indicate either of the Documents or Desktop folders as the preferred save location, both of those folders present as being empty when in fact they both have numerous files/directories. Even if I try to save in "+ Other Locations", those locations are limited to the same as presented in the 'Browse' window of Home, Desktop, Documents and Downloads. Only the Downloads folder displays correctly.

Also as a result of this limited save location, I can only retrieve a file from the Downloads folder (the attached file was saved in my Documents folder but I had to move it to Downloads.

Why does the saving behavior behave like this?

Recently, Firefox stopped asking to save passwords, which has caused some issues. I read that "private browsing" prevents password saving, but is Mozilla VPN the same as private browsing? Do I need to turn VPN off & on whenever creating/changing passwords? Thanks! Melissa B.

Buried in this announcement is the following statement:

"Meanwhile, new features like Tab Groups and enhanced bookmarks now provide built-in ways to manage reading lists easily."

Is this a yet to be announce new feature because as far as I can tell the bookmark implementation has not changed in years. However, I would welcome some "enhancements" as the current implementation is quite clunky.

Thoughts, anyone?

Hi: I've used Firefox for years without trouble and I've even given money! However, I think the last update has prevented my banking site from operating correctly. In Bill payment you choose who you want to pay and fill in the amount. This still works. I move to the month, day, year boxes. If I click, say, on the month box I get a dropdown but selecting the month nothing happens. Ditto with day and year. The day box shows 1 and the year shows 202 and nothing changes when using the drop downs. Can't manually fill in the boxes. At first I thought it was my bank but they said there were no reported problems - they would! So tried Brave and Edge. Both worked perfectly. Tried it on my laptop rather than desktop and same problem using Firefox showed up. I hadn't fiddled with any Firefox settings. What to do? Thanks Donald
