Firefox Community Forum

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?

A white horizontal line in the top of the screen, whilst watching movies in tv5mondeplus.com. This issue happens when installed the recent update 129.0.

Tested in other browsers and doesn't appear the white horizontal line on top.

I'm unable to watch videos on Crunchyroll. When I try to watch a video, the video becomes a static image of one frame. When I switch tabs and come back to the video, or hit refresh, it changes to the latest frame of the video but freezes once again. I have the latest version of Firefox and am using a Macbook. Per suggestions I have found online, I have tried disabling all my extensions, deleting my cache, deleting the Firefox folder in my ~/Library, making sure DRM content is enabled, and uninstalling and reinstalling Firefox altogether. Nothing works. Was hoping to switch over to Firefox since Google Chrome has banned ublock origin, but I keep running into these obnoxious video problems. The same issue also happens on Amazon Prime Video, but only when I press full screen.

Hi, I love the new, little weather app/temperature icon in the upper left of the Firefox home page. HOWEVER, I really want to change it to a city closer to me. I looked up how to do it, but the directions seem WRONG. I cannot hover and find any way to change locations. Is it because I'm on a Mac? or ?

Can you help me? I'm using an iMac computer... everything works, it's updated, what could be wrong?

thanks, Kathy P.

I am not now able to access the Macy's department store website. Here is the error message I receive when I try:

How do I correct this problem?bold text

In the last few days, a transparent rectangular panel is showing up in the upper right hand corner when I open certain websites--Washington Post, The Nation, and Talking Points Memo, and this morning Kanopy and the Zojirushi website. It often covers functions like login and search. I can *see* the buttons, but I can't click them through the transparent panel.

I recently deleted accounts and passwords that were stored in Firefox under my web browser account. Is there anyway I can get that data restored? I have access to the same email/account in Firefox, but need to restore the deleted website account/credential data.

How can I remove extensions? I'm blocked from Google with the same screen no matter what I do. It says search.funsafetabsearch.com thanks

No answers to how to do this, even googling. The best I get is to click on the 3-vertical-dots icon next to the intended address's url field. No such icon exists, nor it to be found in "Customize Tools"

Macbook Air, M1 — 12.6.8 Firefox 129.0.2

why and or how can i update Firefox. i am running Firefox 126. every time i open the browser the auto update opens and fails to download. i tried loading it through Safari, also failed. anyone have a clear and simple solution? the forum seems to have a lot of complicated work a rounds. any help would be appreciated

I've got a question/suggestion about Picture in Picture feature. Why "Close" button works the same as "Back to Tab"?

Scenario: Close the Picture in Picture video by clicking on the [X] button or Cmd+W shortcut.

Actual result: Picture in Picture closes and Firefox window opens, on the tab containing the video. This is very strange behaviour. If I close the video, I don't want to watch it now. Essentially "Close" button works exactly like "Back to Tab" button - so what's the point? If I wanted to switch to the tab - I would click on "Back to tab".

Expected result: I expect Picture in Picture video to close and nothing else to happen. Don't open the window/tab containing the video.

Thanks

Hi,

This a a problem with the interface of a website, its missing a lot of the sections of text and stuff. The first attachment is what it looks like on firefox, and the following one is on safari. I've tried disabling the security limitations on the site to no avail. I'm on Mac.

Best, Jonathan

Why, each time that I try to log in to Xfinity, do I get a banner across the bottom of the screen asking my cookie choices before I can even log in to Xfinity. Same goes for Safari when trying to log in to Xfinity or Comcast.

This is so strange. Usually cookie selection is after you sign in not before...

I have installed the LastPass extension for Firefox, more than once, but the LastPass icon does not appear in my browser bar. It used to be there, but disappeared a few weeks ago. I have tried to reinstall the extension, but it has had no effect.
