G'Day!

I've been having issues with media playback on firefox.

Almost any video source that isn't from youtube cannot play in firefox, giving the error: "No Video with supported format and MIME type found"

Testing the same video on Chromium has no problems.

Using Fedora Linux on an AMD system. And Fedora Flatpak build.

System specs below if required.

Any idea to get this up and running would be really appreciated. I think I already installed the propriety media codecs for fedora since the problem isn't showing up on chromium it looks like a firefox issue.

It's hard to describe what I mean without an example. I type "tart" into the search bar, and instead of the recently visited Wikipedia page on tarts, the autofill suggestions are full of pages in my history with "start" or "starter" in the title, or even in the URL but not the title. Is there any way to change it so the suggestions only contain the exact words I've typed?

Dear Sir or Madam,

I have spent several hours trying to troubleshoot Firefox slowing my CPU/mouse cursor but have found no solution. I have only three tabs open and Firefox is taking nearly a GIGABYTE OF MEMORY! This is ridiculous and totally inefficient.

I made Firefox my main browser for faster loading times, which are faster, but then it trashes my efficiency by making my mouse cursor jump all over the place, lag, etc. I have 32gb of memory and a decently fast Ryzen CPU from only a few years ago. Gaming rig.

It makes no sense that Firefox slows down my Windows experience.

Please fix! I should not have to go through a bunch of troubleshooting actions to make Firefox not slow my PC down. I have seen many users complaining of the same issue.

Please fix.

Sincerely, McKay

Tell me how to fix the problem I described. I'm using Linux Mint Cinnamon (21.3) on my two Dell Latitude laptops (E6420 & E6430) Another question regarding the Firefox browser is how to contact a insecure web site manager that I have no telephone number for. I shouldn't end the sentence that way.

Issue Description: Typically, clicking on scroll bars doesn't cause the currently focused element to lose focus. However, when I click the scrollbar of an element with tabindex set to '-1', the focus is lost from the currently focused element. I'm unsure if this is the intended behavior or not, but it seems odd to me. I would appreciate it if someone could clarify whether this is a bug or intentional.

Steps to reproduce: 1. Focus on the input element. 2. Click on the scrollbar of the `ul` element.

You'll notice that the input element loses its focus. However, if you remove the `tabindex` attribute from the `ul` element and then click on the scrollbar, the input element retains its focus.

Sample code:

<input type='input'/>

I go on the https://www.medicare.gov website to look at Medicare claims. I get an email from them when there are new summary notices and I click on the link to view them. That brings me to the login page and after I log in I get a page that lists summary notices starting with the most recent. For each notice, there are three links you can click: download, print, and open. I've always clicked "open", which has always brought up the summary I chose, I think in a new tab or window, but I'm really not sure, it's been a while.

This time when I clicked on "open" for the first summary notice, it stayed in the same tab and under the title listing the particular notice I got the following:

" Firefox Can’t Open This Page

To protect your security, api.medicare.gov will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

Learn more… "

So I went back to the original list, right clicked "open" and clicked to open in a new tab and got the same error. As I was writing this just now I noticed that the error message says you need to open it in a new window, so I just tried that instead of a new tab, but I still got the same error message.

Interestingly, I thought I'd check clicking "download" just to make sure I could get my new notices. That opened a new tab and the notice came up!! Now I'm sitting here trying to remember if I used to click "open" or "download" and feeling like this computer drives me crazier and crazier every day I use it!

I am submitting this anyway for two reasons. First of all, if I'm confused other people are probably also confused. Secondly, I want to know if there's anything wrong on my end that I should be fixing or if this is a problem on Medicare's end. Obviously I want to let them know if it's their problem so that it can be fixed.

I just got a notice about a Firefox update but I haven't installed it yet and I haven't tried this in any other browser (I really hate using Chrome, especially for something as private as Medicare, but if that will help you please let me know and I can try it there).

One other thing that may or may not be relevant. I've had my Social Security and Medicare accounts for many years. Recently I received a notice from Social Security that they're upgrading to a more secure login system (sorry I've forgotten exactly what they call it) and said that if you're using an older account you have to create a new login with their new site and it would work across your federal government accounts. I did that but Medicare used my old login information and it worked. I don't know if that would be causing this problem, I don't think they've terminated the old system altogether just yet but I'm not sure. This probably doesn't make a difference but I thought I should mention it just in case.

Thank you for any suggestions you have about this, and please let me know if you think I should notify the medicare.gov people as well.

I've read through lots of instructions, and tried to list a site as an exception to the ad blocker, but it doesn't seem to work. The site that I want to be able to contact me is Rakuten.com. Please help. This seems so complicated.

Helping a friend who is using Firefox without having a Mozilla profile/account who is upgrading to a new PC. - Is there a way to export her passwords to a file and restore to the new PC? Going from Win 7 to Win 11. - Otherwise, can she just create a Mozilla account on her old PC and turn Sync on to transfer to the new PC? I am assuming all her settings will be retained. Thank you very much for your time:-)

A few years ago jscher2000 gave me wonderful instructions for how to create some of the features that were once easy for ordinary users like myself to control through an Extension called TabMixPlus. Apparently there was some big disagreement between the developer and Firefox and they completely disabled it. At any rate, I'm continually frustrated when I accidentally move a pinned tab to a new window while trying to move or resize Firefox. I would like to know how, in about:config, I can create a setting with which I can protect pinned tabs. Thanks.

For months I have been unable to load the Google Meet website in Firefox. I keep my browser up-to-date and have tried different privacy settings, container tabs, etc. Every time I go to meet.google.come, I end up in a redirect loop pointing me to https://meet.app.goo.gl/?link=https://meet.google.com/&apn=com.google.android.apps.tachyon&ibi=com.google.Tachyon&efr=1&ifl=https://meet.google.com/about instead. Clearing cookies and such seems to fix it, until I log back into my Google accounts and the problem starts happening again. Any ideas how to fix this?

Hello. Periodically I need to connect to my employer's VPN. Whenever I do, all of the open tabs in Firefox will not refresh or connect to new websites. This is especially troublesome for pages that refresh periodically like when viewing email. New tabs open webpages fine. I have tried using a "hard reload" (Shift while using the Reload button) on the already-open tabs as well as clearing the cache through the Settings menu. I've also tried changing the proxy settings in Network settings (Configure Proxy Access to the Internet; No proxy, Auto-detect proxy settings for this network, Use system proxy settings, Manual proxy configuration)

Any ideas on how to prevent this problem in the first place or fix it when it happens?

Thanks

Hi, I'm having a lot of problems with forms, and also on commercial sites when I'm trying to purchase items. The buttons are not working, I'm unable to scroll through subsections of a form and drop down boxes are appearing behind other parts of the forms.

It's been doing this for about a month now, I was hoping that a patch would have been released by now to sort the problem. Even this form doesn't work properly. the contact me button doesn't work.

Regards Andy,

This is a persistent issue for many a version. I've tried these config settings too and it still consistently-inconsistent resets it sometimes. app.update.auto (->false) app.update.auto.migrated (->false) app.update.enabled (->false) app.update.service.enabled (->false) DisableAppUpdate (->true)

It does this on closing hanging browser or on system power off (without closing browser manually). Also if setting is set to don't update -> close browser within a minute -> when reopened it is on autoupdate again.

I received a notice when trying to download : We can't connect to server at downloadzip.wolfgangsvault.com . It was suggested that I check that Firefox has permission to access the web ( I might be connected but behind a firewall). Please help . Thanks!

Pressing Alt in Firefox in Linux (Ubuntu/Kubuntu/Linux Mint 22.xx) brings up a top menu, which is hugely annoying as I'm always trying to to a window action if I'm pressing Alt.

The suggested solution is to go to about:config and change ui.key.menuAccessKeyFocuses to "false".

But this keeps reverting itself. (Between every other reboot?). Alt will again bring up this menu.

How can I permanently disable this shortcut?

I got a new Macbook Pro recently and set it up by basically copying my iMac onto it. All works great. Except that the MBP doesn't show up with it's synced open taps on my iMac or my iphone. The iMac doens't show up on the MBP either.

Have I maybe copied some setting that makes the two machines (iMAc and MBP) thinkt they're one and the same? How can I "separate" the devices so that they show up in each other's Synced Tabs lists, respectively?

My email application is zmailcloud.com from Cloudiance. It has worked fine for me for years using Firefox. However, in the last week or so, when I open an email message, I cannot see anything but empty "From"and To" fields. Nothing is in the body of the message, either (see attached screenshot). But, if I open a reply or forward message, everything in the original message appears normal (see other screenshot). This problem does not occur using Micrsoft Edge, only Firefox. Anyone have any suggestions???
