I-Firefox Community Forum

Every time I login on my computer, there is already an open Firefox webpage with a dialog box asking me if I want Firefox to be my primary default browser. Once I click "Set a Default Browse", a Microsoft Edge webpage appears giving me a list of choices of Microsoft application to select to be my browser. Firefox is not on the list. There is also a dialog box that appears on the lower right corner of the screen showing me the steps on how to make Firefox my default browser. The choices are "Show Me How" and "No Thanks". When I click the "Show me how", I am taken to Firefox setting, once I click the "Make Default" I am taken back to the list of Microsoft applications to choose as my browser. The bottom line is I cannot make Firefox my default browser anymore. In fact, I am not even sure if I am sending this message to Firefox or Mozilla. This is the URL that I see on this https://support.mozilla.org/en-US/questions/new/firefox/form.

Would you please check and correct the problem. I cannot make Firefox my default browser. Would you check if Firefox is my default browser.

How can I change the settings on Firefox so that only one window opens when I initially open up Firefox? I current get a window with my home page and then two tabs with my home tab.

All of a sudden when i sign in to Amazon I get this box: Windows Security: Please sign in to amazon .com: This request comes from Firefox.........: Never asked for it how do I turn it OFF?? I have no2FA in either Amazon or Firefox but all of a sudden i need to enter a Security Code.

This morning (08/28/25), I updated my browser to v142.0.1 (64-bit), and Facebook as well as other sites have been affected to the point that I can't even see contents now!!!!!!!

I (God forbid) opened the same sites in Edge, and there's no problem viewing them on Edge.

Is there a way that I can roll back this latest update, because I had no problems until this morning. I'm running a Win 10 Pro OS.

Best regards,

At the beginning of 2025, I created a private theme and installed it locally (Windows 10), consisting of a manifest.json and a GIF file. It worked perfectly. Now, on Windows 11, I'm trying to use the theme again, but when I upload the file (.zip or .xpi — via about:addons -> Install Add-on From File), I always get the message that the file is corrupted. However, if I test it temporarily under about:debugging, it works immediately without any issues.

I would really appreciate a solution! <3

Hello Mozilla Support Team,

I recently noticed a file named Newtab@mozilla.org.xpi on my system and wanted to confirm its purpose. My Firefox browser is working normally, and I have not observed any suspicious behavior, but I want to make sure this file is legitimate and part of Firefox’s features.

Could you please clarify if this file is a standard component of Firefox, especially related to the new tab page functionality?

Thank you for your help!

Best regards.

I just received a toast from a sidebar app. Unsolicited notifications are the fastest way to get me to dump your app. I recommend Mozilla implement user-level control to disable notifications from sidebar apps. In theory, Mozilla is already supposed to be respecting my preferences on notifications. I have authorized notifications from only one website, and it wasn't the one for which I received this notification. There's a disconnect there.

Hi, just to say, sorry, I’m an absolute idiot, I don’t understand tech at all. I have a VPN, privacy badger and ublock origin. These issues continue whether these three things are turned off or not, so I believe it must be to do with my Firefox settings.

Everything was fine, but now all of the sudden, certain elements of pages will not load.

So for example, today I tried to go to Gizmodo and look at a Star Trek page. Cool. https://gizmodo.com/star-trek-day-announcements-include-a-lego-collaboration-and-a-youtube-kids-series-2000655142

This is not the only site, just an example.

Clicked the comment button to see what people are saying. It won’t load the comments. The comments are completely blocked. They don't exist. When I try to look at the comments, it just shows me another part of the webpage, can't even see the comments.

Thought it was just this site, but then today I was on a plastic surgeon site in Europe to make a payment and it wouldn’t load the payment page.

I tried turning off badger and unblock to make the payment, and it didn’t work.

Honestly I really have no idea what the problem is, I know I’m doing something stupid but I don’t know what it is or how to figure out.

Any help on figuring out what’s going on or where the hiccups for these might be would be welcome.

Thank you!

Depuis la dernière mise à jour, Firefox me demande le mot de passe principal à chaque ouverture de Firefox. Je ferme ou j'annule et ça marche sans avoir à renseigner mon mot de passe principal. (c'est agaçant !!) La procédure préconisée par Firefox (menu-paramètres-vie privée et sécurité-identifiants et mots de passe-décocher la case à côté d'utiliser un mot de passe principal....... ) ne change rien. Merci

Hello there, I usually use Firefox as my browser to access my Gmail account. For some reason, I am not able to open up gmail. I put in gmail and it shows in the search bar the following informaiton--mail.google.com/mail/u/0/#inbox . NOthing else happens, no gmail account opens up. Please help.

From Windows 11 start Firefox v 142.0.1 opens with an entirely blank page - toolbars, graphics, webpage - everything taking over a minute to load up with toolbars and then a further 2 minutes to load www.theguardian.com/uk. Firefox then frequently crashes and on re-start the bookmarks toolbar is empty - yes it is visible. I have been renaming places.sqlite to places.sqlite.old every few days since 27 Aug. The Manage Bookmarks - Library shows all bookmarks when Firefox is behaving but is completely empty when the bookmark toolbar is also empty. Restarting Firefox does not reinstall the bookmarks. The only solution is to restart Windows 11. Any ideas on speeding up and preventing this bookmark problem. Thanks

when I try to open a particular website, firefox keeps blocking it and says its an error. I cannot open this website. how do i get passed this.
