Firefox Support Forum

Last few days , my laptop( windows 10) system got hanged for some reason. Then second time I got the message on my laptop , that Software Mozzila Firefox got crashed. It had stopped working for few minutes then I restarted it. 1) Has it happened to my System? 2) or even others got the same experience? 3) How to start PC when windows stopped working Suddenly. 4)Was the Mozzila Firefox failure / crash, was the reason, behind PC not working during first time? 5) On laptop a message appears , to upgrade Operating system to Windows 11( currently it is windows 10) from MS. What is the suggestion from Mozzila/

The txt document codes I was given to save to my computer were corrupted in a recent windows update gone wrong. Can you give me those codes back, or are there other routes I can take to correct this?

I have tried both Google Authenticator and Guardian for use with Mozilla 2FA. I have tried scanning the QR code on my PC multiple times on each authentication app and retrieving multiple codes each time, but all entries stated "incorrect 6 digit code" on my PC to enable 2FA. I am not sure how this is not working. Both authenticator apps identified my correct login email address associated with my Mozilla account so I know it must have something to do with whatever is happening on the back end at Mozilla for my account.

Also, I have read a few posts in the Mozilla support knowledgebase regarding this very same issue, but did not see any resolution. I would really like to have 2FA. Can someone please contact me about this?

I am trying to download a .msi installer from the Dell servers at https://dl.dell.com/serviceability/catalog/SupportAssistx64-3.12.3.5.msi using Firefox v106.0.1 but when I click on that link it opens in a new tab as garbled plain/text (see attached image). If I right click that link and choose "Save Link As" then I am able to correctly download the .msi file.

I have no problem downloading this .msi installer using MS Edge v106.0.1370.52.

I don't think there is a universal problem downloading all .msi installers with Firefox since I can download the latest 64-bit .msi installer for Firefox (Firefox Setup 106.0.1.msi) from https://www.mozilla.org/en-US/firefox/all/ without a problem.

I found a comment by jsche2000 in rkm's July 2017 thread clicking on msi link displays garbage rather than download msi file that "usually the problem is that the server is not set up with a specific content-type for .msi so it sends a default content type such as text/html or text/plain that Firefox dutifully displays in a tab... Unfortunately, there's no built-in way to tell Firefox 'when you see a .msi extension, ignore the content-type indicated by the server and just save it' ".

Before I contact Dell and ask them to fix this problem on their download server, is there any possibility that Firefox v106.0.x has introduced a bug in the way this browser recognizes the specific content-type of some .msi installers? I'm not sure, but there seems to be a change in way that Firefox downloads files in v106.0.x. For example, when I download the latest 64-bit .msi installer for Firefox from https://www.mozilla.org/en-US/firefox/all/ my Firefox prompt now specifically declares that I'm downloading a Windows Installer Package (see attached image), which I don't recall seeing with previous versions of Firefox.

When I try to log in to my account at t-mobile.com I get the message that Firefox is not supported in incognito mode. https://www.t-mobile.com/unsupported_firefox_incognito

Logo Corporate Firefox is no longer supported in private mode

The Firefox browser is no longer supported in private mode on our site. To continue, please take Firefox out of private mode or choose another browser. We recommend Chrome, Safari or Edge.

Do I have to compromise my privacy and security just to use the t-mobile.com website?

This happens only on the t-mobile.com website and only after I try to log in to my account. If I don't try to log-in to my account their website works just fine with Firefox.

Thanks for any help on this situation.

firefox has just automatically updated when using private browsing all dropdown menus appear as white text on a grey background this is harder to read i want black text on a white background

I've just opened Firefox to discover it has updated whilst I was out, and now all my saved logins are missing.

It's not a disaster, just really annoying as it means having to re-enter a lot of information, and remembering it!

Is there any way of recovering that information or is it a lost cause?

Hi, I'm migrating to a new PC and followed the below article to open all my currently synced tabs from the old machine on my new one: https://support.mozilla.org/bm/questions/1357426

The issue is that the on the new machine when I open all synced tabs, the order is reversed, i.e. my latest tabs that are on the right on the old machine are now on the left in my new machine. How do I tell open all tabs to keep the same order in the new machine? Any help is greatly appreciated..!

Thanks! manoja

Is this a known issue for the new update? Whenever I try to click Recently Closed Windows in particular, it just does nothing. It has the grey highlighted bar that shows it wants to do something, but then does nothing. About 1 out of 100 times when i click Recently Closed Tabs, it WILL open to show my recently closed tabs, but generally does the same thing as Recently Closed Windows. I know I have recently closed tabs because I restored session and it is currently showing all my old tabs I had open prior to the update. I also tested to see if my recently closed had just reset by opening a new window and closing it, but it still just does nothing. I use the Recently Closed Windows quite a bit and it's quite irritating that it appears to be broken.

I shutdown my firefox browser and was running top on my linux POP_OS 22.04 laptop.

I noticed a firefox process running at 23 to 25 % of the cpu even though the browser was closed. Can you tell me what is running and how I control it?

Getting sick of this crap that everything has to have this BLACKNESS crap in it, 13% of the population shoved in everything, You never see Asians, or any other race now, it's always this black crap, everything in now divershittyfied.

Is it possible to request a feature for Firefox called "Link to Highlight"?

Chromium based browsers have a feature where you can make a selection of text on a webpage and in the right click context menu select: "Copy link to highlight", which copies a link to the webpage, with an appended selection like so: "#:~:text=Steps%20to%20reproduce%20the%20issue%3A". Then when the link is clicked, the Chromium based browser would scroll down to the match of the text, flash a colour to show where it is, and tint the text with a subtle highlight. The text in this example would then be "Steps to reproduce the issue.". This helps in my workflow when using a browser, so this feature would make me super happy.

Well, I have applied all the options about proxy settings with the same result of long time for opening websites when first start of firefox. During these months I took notice to the one point, i.e. if I open website using firefox in the earlier morning there is no problem with the speed of opening as well as if I open another browser of edge the last one opens website without any delay. So the challenge of long time opening websites when the first start of firefox is still in force. How to resolve this?

Recently I started a new job and received a laptop, so I've been setting up the laptop with all my stuff, including Firefox. At first I used Firefox's account sync feature, but it doesn't sync everything - my extensions' settings (not the extensions I have but what their settings are), my toolbar customization, all the sites I'm logged into, and maybe some other things are not sync'd. So instead I tried a different solution which has worked for me before - copying my profile folder on my PC and pasting it into the laptop. This mostly works, except suddenly Firefox warns that a lot of my company's websites are a potential security risk with the error code SEC_ERROR_UNKNOWN_ISSUER. I can get past this, but the real problem is some of these websites - namely GitHub - don't load any CSS anymore. I can access the site but it's ugly. Normal GitHub works, only my company's GitHub (which has a different URL) doesn't.

If I switch back to the other profile, it works. But I'd really like to avoid having to manually sync up my extension settings and other things. Is there any other way to resolve this? Thanks.

I set my browser theme to a customized green theme I made myself with firefox color, then I decided I wanted something different and installed a new theme from the addons page. It works until I close firefox, but if I open it again it changes back to the custom one I made? I can't find any settings that fix this and i don't want to delete the custom themes I made just to be able to use one of the addon themes I have saved.

I just opened a pop up that you sent - asking to choose a colour. I had no idea it would change the look of Firefox. Please could you instruct me how to change it back to how it was.

This green is not OK.
