On our web site we have a page that includes mp3 files, which play okay on Firefox; but on another page on the site with mp3 files, Firefox (including different versions on different computers) produces the error message, No video with supported format and MIME type found." FWIW, other browsers like Safari (Mac), Chrome (Mac and Win), and Edge (Win) all play the problematic files without a hitch.

Is there a fix for this problem that can be attempted by the non-tech types?

I get a weird green mark on the top left, which looks like some type of greenscreen cursor input thing. I have seen it on Gmail. Not sure where else. Last time was a while ago.

This is on Windows 11. Just worried if this is some type of backdoor thing.

I recently bought a new computer and transferred all the data from my old computer to this new one. My old computer was running ESR, which was transferred to my new computer.

Without downloading a fresh install of Firefox and having to lose everything, is there a way to simply move over to the release channel of firefox? I tried syncing it up with my account but I still lost my history. Fortunately, I still have the ESR version of Firefox on my computer.

I tried to import but Firefox ESR wasn't an option.

I cannot figure out why this important site which I have used for years is suddenly being blocked. the message I'm getting says-"Firefox has detect that the server is redirection the requested address in a way that will never complete. This problem can sometimes be caused by disabling or refusing cookies." I don't believe I have made any changes to cookies or anything else in the past few days so I don't know what to fix.

Please help

I was told my bank that there has been an issue with firefox since the last upgrade. I can sign into my account, but if I try to do anything or click on anything, the site locks up and I can not do anything except for sign out. They told me that it was on your end and that you needed customers to reach out. It's becoming frustrating that I can't use firefox for this application. I can get into my account and do what needs to be done with other browsers. What can you do on your end. The bank is Mission Federal Credit Union. Thank you! I look forward to hearing back with good news!

I noticed today that there's a small blue cube appears at the tip of the mousecursor inside a firefox window , I guess it's some keyboard shortcut I accidentally activated but can't find any info on where to disable

How do I get access to a page that is unsafe if I want it. As I do service a lot of old machines and it is anoying that I have to use all the time a different browser because of not getting thrue to the page if it is for example only http:// and has not Cert.

This anoying feature is very bad as it is destroying the usage reason of firefox.

I have a website that I go to frequently that does not require a username, only a password. However, on Firefox it insists on a username, and won't let me enter the site without one. The website owner simply does not require a username. I just tried to check into another site and it insisted my password was wrong. I had just changed it and knew it to be correct in format. This relay system is screwing up my browsing and I want it off my machine. Help me!

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?

Installation aborted because the add-on appears to be corrupt. OmegaSwitch

Hello, I encountered an error when trying to install the extension. I've never encountered anything like this before

Similar to the issue described in this thread (https://support.mozilla.org/bm/questions/1240674), I am unable to open Firefox - it simply refuses to open. I've tried multiple times, the option key, and re-installing. Nothing seems to work, which suggests something about my user settings is the issue, but a) I am not keen on deleting this if possible and b) I won't delete my user settings unless that is necessary. Like the attached thread, I am happy to attach crash reports, but without the ability to even open Firefox properly it's not obvious how I do this - force-quitting it just sends a report to Apple.

Any help much appreciated - I'd quite like Firefox working again.

My laptop is a MacBook Pro 13 2020 (Intel) running macOS Monterey (12.7.4). I installed the version of Firefox available for download as of writing (v127.0 based on Finder).

My bookmarks/settings bar on my PC now only displays the address bar. The search bar, which I regularly used, has vanished and I can't find a way to restore it. A reset to default does not help. Thank you in advance for any help.

Some sites stopped opening, although in other browsers, and through the phone everything opens up. I've tried reinstalling the browser, disabling extensions, resetting DNS. It didn't help. A list of sites I'm having trouble with: https://www.deepl.com/ https://enka.network/ https://7tv.app/ https://hsr.hakush.in/ and some other sites that I can't remember right now. In Chrome he working. Sites like youtube twitch and other poplar working too, idk why firefox have problem, maybe its new update?

I have been a devoted Firefox users for many years. Just in the past week or so I have started having multiple tabs crash daily and now am getting 1 or 2 blue screens a day. I run on Windows 11 Pro. What can I do to help this issue?

Hi, Just received your "Webpages, simplified" notice and it triggered two improvements you can easily make so Firefox is more accessible to users with disabilities.

• Make buttons more descriptive "Learn More About Reader View" makes all the difference to someone using a screen reader. Imagine skimming a page where all the links just say "Learn More." This is pervasive across Firefox and easy to fix! (See screenshot of your page, attached.)

• Add link to accessibility features or Mozilla's accessibility statement at the bottom of every page. I should not have to do a search to find out about accessibility. See example screenshot from Univ. of California, attached.

Since the auto-update to version 128.0.3 (64-bit) two weeks ago, my Firefox crashes as soon as I switch over to a different programme. I am on Windows 10. Whenever I try to re-open the programme, I get the error message that Firefox is already running and if I want to restart or quit. Can you please deploy a fix for this? Thank you.

After your an update some weeks ago, I have not been able to access my bank account using Firefox. Got some advice from support from the bank, but since I have an US version, the labels to be accessed differed, and were not compatible with the advice. Presently using M Edge, which I of several reasons don`t want to. Any suggestions?
