Firefox Support Forum

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

Firefox browser, v123.0.1, 64-bit. windows 10 Pro, 22H2.

Hello, this may not be a problem with Firefox itself at all, but I'd like to try to understand what the cause of the problem I and others are having.

I have Norton 360 installed, in this Windows 10 computer and like to use Firefox for internet browsing, it has always served me well.

I also have Norton Safe Search integrated/add-on to Firefox. This puts a red, green, or gray check mark at the end of each link that comes up during a search and has always worked before.

Recently, I've noticed that such check marks do not appear at all when doing a search with Firefox, but they are present when I do searches with MS Edge.

I am searching for a solution here, and also in the Norton Community. There are others there who have stated they are having the same problem.

Has anyone here heard of this before, would you have any suggestion as to what may be causing the lack of the Norton Safe Search check marks in Firefox searches?

Any input/suggestions would be welcome.

Hi there,

I'm curious if it's possible to configure Firefox on your own to make it a portable browser. Specifically, I want to disable data encryption and machine ID checks. I know that some chromium-based browsers allow you to do this through specific switches that turn these features off, resulting in a fully portable browser. While I'm aware of third-party applications that offer ready-made solutions, I prefer not to use them for security reasons. I'd like to prepare my own version of Firefox.

I understand some may have security concerns, but I know what I'm doing. The files will be stored on an AES256 encrypted drive. Could anyone share insights or guides on how to achieve this with Firefox? Thanks a lot

PS.For those who might suggest using synchronization, I assume that, similar to Chromium, Firefox can't sync all plugin settings, and for me, plugins are essential—without them, it's not really a browser.

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

Many questions and answers I see regarding the sync function. I would like to know the depth of what Firefox does. I have multiple PC's and an Android. What is the depth of sync for extensions? Is it possible to have mirror images of the entire Firefox setup duplicated? It would be spectacular to move from one PC to the other and find that Firefox has the exact same setup.

Every time I restart firefox, my spellchecker languages disappear, leaving me only with one - the addons are still installed, they're just not available to be selected. Even now I can't spellcheck in english. Please help.

When I open firefox in ubuntu linux. (WSLg) Fresh install. I can't go to settings in firefox. Steps: press the hamburger menu, press settings, nothing happens.

My Windows 10 PC stopped working a few days & is disconnected & partially disassembled. I’m temporarily using an old Windows 7 PC which I brought up from the basement the following day. They both have Firefox on them.

I saved one bookmark on the Win7 PC today. It was there when I looked earlier. Now I went to use it again & it’s not there. But my Win10 bookmarks are there!!

How could that be?

What the title says. While I was doing school work my session crashed and I lost all of my work. Upon reopening Firefox I was told my browser had installed the latest update for Windows. I then checked my crash logs and saw my session had crashed and Firefox had installed the update. Why could have this been? I would like a solution to this to ensure this doesn't haven't happen again. Thanks.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

In firefox Ubuntu (WSLg) the dropdown menus don't work. I have already tried reinstalling both firefox, and the entire OS.

When I press Custom URLs... (see image) nothing happens. This issue is everywhere in the brouwser, on websites, even when I press help in the hamburger menu. (Or settings in that same hamburger menu.)

i am using firefox developer edition version 126.0b3 (64-bit) on linux mint with an x11 desktop and for some reason the drag and drop breaks frequently.

i think i have figured out how i can consistently recreate the bug as well as sort of fix it temporarily.

i start with a newly launched browser. everything works fine. but then if i attempt to drag and drop something shortly after i drag and dropped something else and it did the little animation where it returns to its original position, i find that i cant drag and drop anything FROM firefox to anywhere else. and i also cannot rearrage tabs.

it seems to fix itself whenever I drag something from another program TO firefox successfully such as text into a textbox, or a .html file into the window to view it.

I think with the update to 125, I no longer see the typical Windows window controls in the upper right - minimize, maximize, close - so I don't know how to do those things.

THe top right looks like this Mac-based image (where those buttons are on the upper left) but I'm running on Windows so I don't have the dot buttons on top left nor the Windows style min/max/close at top right.

What do I need to do to get them back?

I have uninstalled and reinstalled firefox and restarted my computer but it still will not load. When i first reinstall it it comes up but will not connect to the intenet.

I reinstalled the Visual C++ and Firefox loaded when i ran the Firefox repair but totally locked up. Unable to get to settings or any website and will not run after closing it.

So with Google becoming an increasingly terrible company over the years I once again decided to try to move away from chromium based browsers and over to Firefox, but I'm still having the same problem as I did when I first tried. I have since found the source of the problem, or rather a more exact explanation of what is going on, but I still can not find a solution. Basically when I compare the audio of the same YouTube video while logged into the same account with the same settings the audio quality on chromium browsers seems better. After some testing I figured out that it has to do with Logitech's G Hub surround sound option. Using Logitech's surround sound on headsets that support it, the Pro X2 in my case, will change the audio quality by quite a lot, in my opinion it sounds better. The problem is that this change doesn't seem to have an effect when using Firefox.

Is this a known issue and if yes, is there a solution?
