After new update I am unable to drag and drop files to attached to Outlook 365 web email. I just installed the 99.0.1 update and this didn't fix it either. After a web search I noticed that many others are having this issue. Are we working on it?

What is going on?

After doinf a reset to try and get rid of the yahoo redirect malware attached to the Firefox browser, now I cannot access google search engine within firefox, or my gmail email account. I get the error messages attached below. I have spent hours looking on your support pages and tried all ways and NOTHING WORKS!!!!

FIrefox has been my default browser for years but if you cannot fix this very annoying and frustrating bug, I will be forced to your Chrome.

Very unhappy with this

I am using a MacBook Pro and latest version of FIrefox 100.0

PLEASE HELP ASAP!!!!!

Since the last update [76.0 (64-bit)], whenever I enter a fullscreen mode in any media player on a website (e.g. Youtube) I can no longer Alt-tab normally, even if I close the fullscreen. Instead it takes 3 times to switch to another window - first press of the Alt-tab combination causes Firefox to lose focus but remain on top, 2nd press returns focus onto Firefox and then the 3rd one actually switches to another window.

This also occurs when simply switching to fullscreen on any other website as well (by pressing F11).

This also causes any newly open windows to be displayed under the Firefox window.

Pressing Ctrl-Alt-Esc minimizes the window normally and the issue does not occur then, however, it occurs again whenever I go fullscreen.

The problem occurs also in the Safe mode. Antivirus did not find any issues, so I don't believe the cause to be external.

OS is Windows 10 Home, 64-bit.

I'd like to know why when I use Firefox often google asks me to show I am not a robot. Yes I use a VPN but this does't appear so often using Chrome. Thank you for any information

Firefox won't close. The icon is there on the Bar, but putting the arrow over the icon brings up the last page open, which won't close (using the X in the upper right corner), or open on the screen, (either by click or double-click).

Morning, every time when I click on a link on a website which should open a pdf document, firefox start opening several (infinite) new tabs with the document. Even if I close Firefox completely the process will continue if i open Firefox again. This can only be stopped when I smash the Strg+W Puttons to close all the Tabs faster then they are opening.

I hope someone can help me with this. It is really annoying when it happens.

Thanks and best regards.

Hi,

I only want to mention that Firefox hangs on download, if I want to download VMWare Player for Windows from https://my.vmware.com/de/web/vmware/free#desktop_end_user_computing/vmware_workstation_player/15_0|PLAYER-1555|product_downloads

After clicking the button for the download destination nothing happens and reacts anymore and I have to kill Firefox. The dialog for choosing the download destination won't be opened. (Winodws 8.1 Home 64bit)

IE 11 works well.

Everything has vanished. I've tried all suggested fixes. I even deleted Firefox and installed again. I continue to get the same error msg..."the bookmarks and history system will not functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I'm using Webroot and have not made any changes ...period. Any help would be appreciated. Thank you. Scott

Firefox has been my default browser forever but suddenly has started glitching! It will work for about 10 minutes but then the glitch happens and all of the top of the screen loses its text and turns into black/white color boxes that looks pixelated and the whole program freezes. In the picture posted, the glitching continues down the right side of the screen too. If I quit Firefox, it starts up fine again (with all browsing tabs lost) but then the error will occur again in a short while.

I believe there is a bug. I can't get naturalWidth / naturalHeight in Firefox. Neither Safari nor Chrome has this problem.

JavaScript code:

let image = document.querySelector("img"); console.log("natural width=" + image.naturalWidth + ", " + "natural height=" + image.height);

The code printed a value of 0 in Firefox whereas browsers printed the respective width and height of the image.

I just posted a question asking for help because I kept getting an error message saying that Windows couldn't locate Firefox.

I just figured out how to fix it. I copied the exe file and pasted it back into the program folder as a copy.

The copy file works fine.

I have allowed notifications from Facebook and Instagram but I'm not getting any. I also tried clearing cache, cookies and even resetting everything. Nothing worked.

Hi. The attached "authentication required" popup occurs intermittently in the Firefox browser. I have no idea what it is referring to. Clicking cancel removes it. It does not appear to interfere with any Firefox operations. Would just like to know what it is about and how to prevent it from appearing if not necessary. Thank you in advance for any assistance.

when i click on a firefox tab it opens in a new window. I use linux mint. Firefox 77.0.1. I have checked in safe mode - problem persists Refreshed firefox - problem persists re-installed firefox - problem persists.

What can I do - I do not want to use another browser

I have rather abruptly lost all audio in Firefox 77 on Windows 10. YouTube, Netflix, Amazon Prime Video, Facebook videos - all silent.

Meanwhile, I'm getting sound as usual when viewing those things in Chrome (and I would really prefer not to have to go back to Chrome), and all sound from other sources is working correctly - games, iTunes, Spotify, etc.

Does Firefox hook into my system's audio functions in some unique way, different from everything else? I've recently started experimenting with doing my own music and video recording/editing, and I've tried out a number of different audio/video apps in an attempt to find the tools that suit me, and I'm starting to wonder if one of the apps I tried modified or overwrote whatever system hook that Firefox was using.

Strangely enough, the audio spontaneously started working again yesterday, a few hours after it stopped, and was still working today until I rebooted my machine. Then it was gone again.

every time when I am on my Facebook acct browser gets too slow or it does not load the content of whatever I want to see and on top of the screen under the command for Facebook a yellow strip appears and it says A PAGE IS SLOWING YOUR BROWSER.. I have this problem for a few months already and what I do is close the browser in all windows that open and re initiate the whatever I want to see after I closed all tabs on the browser

I have a completely fresh install of mozilla on my laptop *HP Elitebook 8470p*, it plain refuses to load webpages, and it seems to be the only browser to have this issue.

It has the following specs: a I5 3340M 8GB DDR3 RAM at 1300MHz Integrated graphics chip

Its running windows 10

Is this a case of the specs being utterly lacking or am I missing something.
