Firefox Support Forum

Firefox (x64 en-US) is our primary browser on 2 different computers: a desktop and an HP laptop. Within days of each other, both Firefox browsers on the two computers began crashing whenever we tried to use them. There has been no error message. Nothing we have done has helped, though we have only tried to fix it on the desktop. We have uninstalled it and reinstalled it on the desktop. We have refreshed the reinstalled version. We have opened it in Troubleshoot mode and it still crashed within 15 seconds. Below are the 4 most recent crash reports from today's crashes:

Hello, can you add better support playback on .mp4 videos? Seems with Firefox it's a hit-and-miss with some .mp4 videos that will play and some that will just show "No video with supported format and MIME type found".

All other browsers will play .mp4 videos without an issue but Firefox won't.

If you can provide better .mp4 playback support that would be greatly appreciated. Thanks

Here's one of those videos for an example: https://drive.google.com/drive/folders/1Fv6SdftiCXeYPQOdF17H2JNpwjMu9P7q

Pretty much a URL string like example.com/videosample.mp4

Good morning I would like to ask how to configure (set) the Firefox browser on a computer with Windows 10 so that when clearing cookies and history, cookies and login data that have been added to exceptions are not cleared (deleted) when closing the browser: How this setting should be done (what options are selected) Privacy and security - clearing history when closing the browser Privacy and security - deletion of cookies and site data on closing (exceptions - allow) Please reply Regards Zbigniew M zbigniew14@gmail.com

Oddball minor problem I've encountered on a recent update of Firefox, but also I switched keyboards at the same time, so I'm not sure which causing the problem. I'm on a PC, using an MSI keyboard. Ctrl and Shift keys all work, the ONLY combination that doesn't work is (left) Ctrl + (left)Shift + P. Other Ctrl + Shift key combinations work. If I hold the right Ctrl and either shift, P works fine. If I hold the right Ctrl and the right Shift, P works fine. (left) Ctrl + (left)Shift + any other key shortcut in Firefox or elsewhere works, it's ONLY the P shortcut and only in Firefox and only with the left two ctrl+shift combo that doesn't work.

Any ideas on what is causing this and how to fix it?

My online pharmacy, connected to HumanaCenterWell, no longer opens in Firefox. A message "forgerock, redirect_uri_mismatch" appears. It did work until a few months ago and it does work on Google.

I have Firefox set to ask me where to download files that I want to download. It works for normal download links, but when I'm using my credit card company site's PDF viewer to look at a statement and I click on the download icon or link in the upper-left, it simply downloads the PDF (to my chosen "Save files to" folder in Settings). Is there a current way to change this behavior? Is this something that the website's code determines, overriding my Firefox setting?

Similar issue to the other posters. Firefox doesn't support streaming from amazon, netflix, or disney+. I have windows 10, a PC, an updated version of the browser, DRM content is allowed, and my widevine plugin has been updated as of today (12/10/23). Disabling all of my extensions did nothing to help. I can stream on apps and other browsers. Please work on a fix soon, or let us know what to do. Thanks.

Hi,

Ever since installing the latest Firefox update I can no longer access Microsoft Outlook - email. When I try I get the following in the search bar https://outlook.live.com/mail/0/. Then nothing

I can access my Onedrive account, no problem, but when I try to get to the email part I get the same search bar response. Then nothing.

Using MS Edge, no problem - all works fine.

I have cleared all temp i/net files, cookies etc

Any (simple!) ideas gratefully received

Thanks -

Jim

Why am I seeing pop-up windows with ads for this online women's cloting store: https://www.lightinthebox.com

Sometimes in the background firefox will start to max out my ram usage (32GB). I am not sure if it is a addon or a site which is doing this. I captured a memory measurement, but not sure what to make of it. I don't have anything to add up parts or anything.

What is weird, is when I go back to firefox and tab through my tabs it will go back down to a reasonable level.

Video on https://www.abbeyroad.com/Crossing is suddenly unable to be played after to last Firefox update!! This has happened several times in the past but after 2 or 3 days it suddenly will start working again!!! It's been over a week this time and no resolution yet! Note following LARGE ROTATING X is: "The media could not be loaded, either because the server or network failed or because the format is not supported." Same note as in the past but eventually disappears and video works just fine. The video is a live shot of the Abbey Studio's Crosswalk (ie, the one shown on the cover of a Beetles Album years ago).

You somehow have old, outdated information in your system. Your new browser requires me to log into a facebook account I closed 10 years ago. My password for my current account named, "VangiePangie", now opens a closed account named "Evangeline Custis". I no longer have access to my VangiePangie account with any password. So, I no longer want this new upgraded Firefox account. I want to have my old Firefox account as a default on my desktop. Right now it's an icon at the bottom of the screen, and I can only use it to open one thing at a time. Please give me back my old Firefox browser. I'll struggle with Facebook to get my password to work on my VangiePangie account. I have access to the VangiePangie account right now, because it was never logged out in my old Firefox browser and is in my Bookmarks. But if I am forced to log out, or if Facebook does a security check, I won't have access ever again. Please help me with this. Below is my VangiePangie Profile pic.

I recently sent a lot of tabs from my phone to my computer. However, when I started Firefox on my computer, since Firefox tried to load the content of all sent tabs immediately instead loading them lazily (which I think probably should be the default behavior), it took a very long time for Firefox to display even the tab that was currently selected, and I therefore decided to kill Firefox and reopen it, in the hope that all new tabs would load lazily. Instead, when I reopened Firefox, none of the new tabs where there anymore; it was as if they had never been sent. I would like to get them back, but I have no idea how to. Does anyone know if that is possible and, if so, how?

On Wednesday, 12/6, I got a new work computer. FYI--both old and new computers are Dell laptops using Windows.

So on Tuesday 12/5, I had synched everything--Bookmarks, History, Open tabs, everything. I checked to make sure everything had synched because I knew I didn't want to lose my info.

After I had done that, I also signed out and deleted the history from that old device because it said that wouldn't affect the synched information.

On the new device, I haven't been able to access everything from that sync. I can see that most of my Bookmarks are there but the Open Tabs are nowhere to be found.

In "Connected Service", I see my old device listed but it says the last sync from that device was 4 months ago (that is definitely not the case).

When I look under "re-open all tabs" in Settings it only shows what I've opened on this new device (mostly Help topics trying to figure this out!)

Is there anyway to get back to the most recent sync? Especially but not only the Open Tabs?

THANKS! Christina

WILL YOU STOP THAT PATRONISING "HMM, WE'RE HAVING TROUBLE FINDING THAT SITE" MESSAGE NOW

IT IS OBVIOUS THAT IT SHOULD SIMPLY SAY " NO INTERNET CONNECTION" IT IS INFURIATING.

DO IT NOW OR I WILL KILL MYSELF.

I prefer to have all my previous tabs open when I start up Firefox, which means that I don't want them to close upon exit. Recently, Firefox started closing my tabs upon exit, even though:

- I tried both hitting the X and choosing Exit from the hamburger menu
- I have checked "Open previous windows and tabs" upon startup in settings
- I have not checked "Delete Cookies and Site Settings when Firefox is closed"

- I have the option "Firefox will remember history" selected

- I do not open in Private Browsing mode

What other settings do I need to change? Debra

My website has a branch that is protected with username and password. At the prompt I enter those, exit Firefox and start Firefox again. When I go to the branch and this time I do not get the username and password prompt and have free access. However, when I do shift-refresh the prompt shows. Apparently Firefox does save something that it shouldn't. Is it a BUG???
