Diễn đàn hỗ trợ Firefox

I use Outlook.live.com Hotmail and recently a PopUp Message appears asking me to:

Add outlook.live.com as an application for mailto links.

Microsoft Customer Service said it was not something they initiated and likely a Firefox issue.

It does not seem safe to click on a random link like this without any explanation. Each time I log in, the same message appears.

Could someone please explain what this is for and how I can stop it from popping up each time I log into Hotmail?

When i click ctrl only ctrl its maeks tab smaller like ctrl + - but i only press ctrl also when i hold scroll i can smooth surf the tab now it dont work what i have to do?

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

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.

After installing Firefox on a new computer, where everything worked fine, I installed a number of fonts. Afterwards, all of text within Firefox appear to be in some version of Arabic. I have tried resetting, deleting and reinstalling, changing the Firefox language, and deleting fonts. None of these seem to work. Firefox is set to English US.

I enter my search data or search item description into the Firefox window central to the screen, the input word and following description immediately jumps to the URL bar. How can I stop this annoying operation

Open my links with Firefox

Not now

I use firefox on fedora 38 and after update firefox about a month ago . i got this error when use private mode ,for thai languge it just error but in normal mode it ok .

When I pull up my settings, it states that my browser is being monitored by my organization. The problem is that my laptop is my private laptop and not connected to any organization, at least, not with my knowledge. When I click on the link associated with the message, it lists two policy names. One policy value is locked with the word true after it. The other policy value is unlocked with the word false after it. What do I do?

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

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?

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

My "recovery.jsonlz4" file from a previous install will not reopen my previous session (tabs) after the new installation.

Before deleting my previous installation of Firefox (for a clean install), I did two things: I created a restore point, and I did a backup of my old data.

The data consists of: bookmarks-2024-05-10.json

These folders: C:\Users\[machinename]\AppData\Local C:\Users\[machinename]\AppData\Roaming C:\Computer Files\Mozilla Firefox\distribution C:\Program Data\Mozilla-1de4eexxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Within "Roaming" I have Firefox\Profiles\xxxxxxxx.default-release\sessionstore-backups

In that sessionstore-backup, I have a "recovery.baklz4" (most recent session, I'm guessing) and three others that look like "upgrade.jsonlz4-2024xxxxxxxxxxx

With Firefox closed, I took a copy of "recovery.baklz4" (745 KB) and pasted it into the current sessionstore-backups file, then I changed the file to "recovery.jsonlz4".

I thought that when I reopened Firefox, my previous tabs would appear. They didn't. So, I went to the menu, then to History, and clicked on Recover Previous Session. That didn't do anything either. And it reduced the size of the *.jsonlz4 file from 745 KB to 6 KB.

I'm not sure what I've done wrong. Can you help me out?

Thank you.
