Diễn đàn hỗ trợ Firefox

I have both speakers and a headset on my desktop. The system has worked fine for the past 1.5 years. Suddenly today, when I unplug by headset and select speakers for audio, it works for other apps, but not on Firefox browser. Can someone offer some possible reasons for that and, even better, as solution?

using Win 11, Firefox browser, Google search. subfolders are listed but will not open. Using Bing they do open but I prefer Google. If this is a Google problem or a Win 11 can you steer me in the right direction. Thanks My email is artsiii@aol.com

Hello, By default, DoH fails on Max Protection in the latest OS versions listed above. The workaround I've discovered is using https://1.1.1.1/dns-query, but I would rather use the default settings.

CVE-2024-4367 has been announced several days now with MITRE and CIS. There is also an issue/advisory on the github repo for PDF.js which appears that the fix has been merged into the master commit of PDF.js (https://github.com/advisories/GHSA-wgrm-67xf-hhpq).

The vulnerability is pretty serious and yet there is no Security Advisory from Mozilla on affected versions, etc. (https://www.mozilla.org/en-US/security/advisories/)

Is this normal and I am just being impatient?

I haven't been able to login with MFA on my uni website and also make purchases using credit cards on commercial sites.

I have tried Troubleshooting mode and the problem persists. Switching to Opera browser showed normal functionality.

Firefox 125.0.3 (64-bit) on macOS 14.4

I have Mac, Windows, and Linux boxes. All show connected to Firefox Sync, however, bookmarks etc are only actually in sync between Windows and Linux. I've tried logging out on all devices, resetting passwords, reinstalling FF on the Mac. Can't seem to get it to work.

Hello, Firefox randomly downloaded a file, with seemingly randomly name, that is 0 bytes and in download manager the source is moz-safe-about. It happened when I was accessing a popular wiki site. I opened the file in notepad, it was empty. I put it on virus total and came back negative, as it is an empty file. I've curbed through the support tickets here, using the keyphrase 'moz-safe-about'. I understand this was/is quite a common problem, but it still makes me quite worried and left a sour taste in my mouth, as I haven't understood any of the explanations. I have enabled firefox to ask me whenever it wants to save something (I have no idea why this isnt the default state). Happened on a somewhat fresh, updated win 11 installation. I'm also attaching more information here with a picture. Long story short: should I be worried? Am I overreacting and this is just some sort of a bug that occurred while getting a sites data? Thank you for your time.

Hi everyone,

I'm running Firefox which I compiled with vaapi support because I was trying to use hardware acceleration for videos, so I think this bug may have something to do with that. Every time I open a pdf file my browser instantly crashes. When I use troubleshoot mode I have no such issue. I then tried with a fresh all-default user profile with no add-ons, nothing, and still I crash when loading a PDF. Any pointers would be appreciated.

Sometimes I find that Firefox just randomly closes on my laptop, usually when I step away for about 10-20 minutes. I can't find any info in the about:crashes page when it happens.

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.

After accidentally cutting power to my pc, Firefox has been crashing upon start. I've tried using Troubleshoot Mode, refreshing, reinstalling, and even manually deleting all my user data, but nothing has worked. These crashes do not appear in the crash logs, and happen instantly upon opening the program.

Oddly enough, using task manager to restart Windows Explorer stops the crashing, at least for thirty or so seconds (this is how I was able to try Troubleshoot Mode, as well as accessing logs). I have no idea why this is, nor if it's useful information.

I made a private homepage years ago made up entirely of links to web-based AND local folders and files that are grouped into columns of categories like banking, medical, insurance, budget, etc. I keep it off-line on my desktop. I wrote the code so I could place an external link to a bank for example, next to a local link to the folder on my computer where I download statement pdfs from that bank and other bank files. The web page links displays: MY BANK Chkng/Debit Statements Credit Card Statements Bank Information The top link goes to the bank web page on line while the three lower links open folders on my computer where I save pdfs, txt, images, etc from the bank. Firefox opens the folders as "Index of file:///C:(folder path).

My personal home page is laid out with groupings like this for all sorts of information and associated web links: broker, vendor invoices, medical test, taxes, social security, health insurance, subscriptions etc. Today we get .pdf files with all sorts of information and no help organizing it for easy access. The Firefox browser has become the perfect tool for me. But I learned HTML coding years ago! Not so easy to do for others.

Today, many entities have on-line access that provides downloads like invoices, test results, payments, subscriptions, and much more that replace paper. Creating folders to hold these documents with their own local links on your web/local homepage makes sense to me.

While you can use "File" on Firefox to open a local folder or individual file, you cannot save it as a link. However, you can copy the path and transfer that to an a href=" line of link code in your homepage and build on that method. It's amazing how many types of files can be displayed in a browser that are locally stored. Even a link to a spreadsheet file will open that spreadsheets application. Having a varied list of links with quick access is worth the code-writing time. I wish there was an app to help anyone make their own custom folders and links to the contents in a "my homepage.html" . Is there a product idea in there for you folks?

When attempting to load a number of different web pages such as Quickbooks Online Apps, the page displays "Loading Apps..." with a spinning wheel, but never redirects to the Apps page; the site hangs forever. On other browsers there are no issues; it eventually switches to the correct page. In Firefox Browser I have tried adding exceptions in Settings --> Privacy & Security --> Manage Exceptions. No change. Thoughts?
