Firefox Support Forum

Hey everyone, I need some help with a puzzling issue. I've noticed that a website (https://socialhubin.com/how-to-pause-instagram-reels-like-a-pro-uncovered/) I'm working on functions perfectly fine when I use Google Chrome, but when I try to access it using Mozilla Firefox, I encounter a '404 error' or sometimes the layout is broken with images displaying incorrectly. Can anyone shed some light on what might be causing this discrepancy? Your insights would be greatly appreciated!

When pausing/starting or moving video feedback volume changes to an fixed volume. Opening video player in youtube default volume is at 41%, I put in at 100% but when I pause it or change to another part of the video, the volume changes to the default again. It's not from OS because with chromium browsers doesn't happen (brave,steam chromium) and with librewolf happens. Wanted to publish a 10 sec video showing the error, because I don't know how to show it with photos.

A recent set of system updates appears to have made most website videos not play in Firefox.

When I inspect the Developer Tools - > Console tab the most detail Firefox gives are an error line similar to: Media resource URL could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)

Internet searches for the error name and error hex do not appear yield any applicable troubleshooting, nor any methods of collecting additional problem data.

How can I obtain more detail on where the error is happening and how Firefox might be interacting with other packages present on my system?

Arch Linux has some older ffmpeg-compat packages, but those don't appear to match any of the web results, in that they're even older versions of ffmpeg.

yay -Ss ffmpeg-compat aur/ffmpeg-compat-55 2.3.6-4 (+24 0.00)

   Compatibility package for ffmpeg to provide versions 55 of libavcodec, libavdevice and libavformat, not anymore provided by the ffmpeg package

A marquee markdown is not showing in every firefox version I tried (Normal, nightly and dev), none of those versions was showing this markdown. So I'm writing about that. I know it's new, but I think it's very good, and useful markdown.

I'm running Windows 10, Firefox Release 126. I had the same issue with the previous version of Firefox. I was hoping 126, would fix the Chase Bank issue.. But it did not I read several articles from FF users, I checked my User Agent Settings, they are correct. Called Chase, they said use Chrome as Firefox does not have the 'needed code' to work with Firefox. Been using Firefox with Chase for at least 5 years.

Please help, Thank you

Whenever I browse the web using Mozilla (Google, Startpage or any other browser) AND Mozilla is set to fullscreen mode I get black bars all around website screen which are not present when Mozilla is set to windowed mode.

I am using: Macbook Air M1 (MacOS Monterey 12.6.6.) and latest Mozilla web browser. I have already tried this solution: "go to about:config in the address bar and try changing the value of full-screen-api.macos-native-full-screen to true" and it did not fix the issue. I am experiencing this for a lot of time now and only on my Macbook which means a specific version of Mozilla cannot be blamed. This happens on ALL websites. Note: I did change about:config quite a lot regarding privacy alterations.

Using Firefox on windows 10 pro, 64 bit

Since updating to Firefox 125.0.3 (64 bit) , I am getting all sorts of website problems with font sizes. Some are all extremely small like on google news, others have widely mixed sizes, extremely large and extremely small. Even on this page, support.mozilla.org, I have to zoom 250% to make it readable.

I tried troubleshoot mode and there is no difference. The problems are still there.

I tried the Edge browser and the problem is not there.

I didn't have this problem before the update. I tried adjusting windows and the screen dpi, but I can't find a solution. Just seems to make things worse.

Anyone else having this problem? Any suggestions for a solution ?

I cant select rows that shows a name and date

Lines or part of the line are lost in the copy

This is not a problem on Chrome

The Copilot website text field is the only text field I have encouraged where typing text does not get automatically underlined for spelling mistakes. I have the box ticked for 'Check your spelling as you type' in the general settings, and I have tried changing the about:config layout.spellcheckDefault value to 2. Nothing has worked.

The spell checking feature for the Copilot website text field can be enabled, but you have to manually enable it each time by right clicking the text field and making sure "Check Spelling" is ticked. It is quite annoying.

The "Check Spelling" setting on every other text field from every other website like this very text field I'm typing into right here right now for this firefox support forum, has the  "Check Spelling" setting ticked by default.  

Anybody else experiencing this issue?

Getting application errors on some sites – but the same site works in other browsers. This has been happening over the last couple of weeks – getting application errors on some sites but not in other browsers. On the example shown I see the login page flash briefly then replaced by the error.

When scrolling down through the YouTube home page, the current tab will crash and end up as a small window near the bottom right of the screen with a totally blacked out screen in that small window.

Only solution is to close that little window and open YouTube in a new tab... which will eventually crash the same way.

I have disabled the tracking shield for Youtube.com Problems are even worse with the tracking shield enabled.

These type of problems started with version 125. I hoped things would be resolved with 126 but problems still persist. Other websites have issues as well. Mostly with image displays such as on carfax.com when trying to view photos of cars with their photo scroller widget.

I'm not having these problems with the Edge browser.

Hi there,

I read books using Amazon Kindle's cloud log in. After installing Firefox 126, I am no longer able to open books on my last page, I cannot turn pages or even open my notes. I tried using Kindle cloud on other browsers and everything works fine.

Any idea why my Kindle cloud functions are not working on Firefox?

Can't log in to Regions Bank Account. Message: "We can’t locate that page right now." after typing in password Works fine on other browsers.

Problem started Maybe around mid April. Have 5 computers: 2 running Windows 10, 2 running Windows 7 Professional, 1 running Linux

Problem occurs only on the computers running windows 7 Professional

Regards.

I'm a university student using a website called canvas to access my uni information and work. Today, whenever I would open a module, the page wouldn't load, meaning that I couldn't access that information at all (refreshing, restarting, and completely turning off my computer did not help). I can access these pages when I checked with microsoft edge, similarly I could access these pages when I accessed them with my laptop (also using Mozilla). The main difference between my pc and laptop is that I had just, today, updated my PC to the latest windows update (2024-05 cumulative update for windows 11 version 23H2 for x64-based systems). I'm not entirely sure if it's a Mozilla problem, but im guessing that something funky is happening to my browser with the latest windows update. I have attached pictures to show whats happening / not happening .

Trying to use this site: https://www.asraymond.com/mechanical-wire-springs/compression/spec-metric-compression-springs-131626/?Imperial=false

Near the top of the page on the right hand side you can switch from imperial to metric units. The link is set to metric values, but the search input is still using imperial dimensions (see this on the left side of the page as you scroll down) But it works in Chrome!

The is one a myriad of problems I have encountered with Firefox. My installation at home frequently stops searching. It won't perform a web search. Typically when I fire up Chrome in frustration to this constant event, Firefox starts working again. I have removed and reinstalled Firefox, but this did not solve the problem. It's my understanding the Google finances Firefox. Are these problems intentional?

This problem exists ONLY on Firefox. I vary search engines, from DuckDuckGo to Presearch and Startpage depending on the search results I get.

For no apparent reason I will get a "suspended connection" message on Startpage while using the Firefox browser. I have included both the link and a screenshot of the problematic page. The page will open perfectly several times, and then suddenly, in the same session, if I open a new Startpage tab, this message will appear. While the suspended connection message is visible in Firefox / Startpage, I will try Startpage in Edge, Opera, Chrome and Midori, and they all open to the Starpage beautifully.

I am using the Firefox 125.0.3 browser, I have cleared caches and cookies, and run full malware scans, with zero negative results, and yet this problem persists. It is sporadic, and does not occur on a predictable basis. It occurs whether the Mozilla VPN is on or not, and switching from on to off or off to on changes nothing, even after refreshing the page.

I am assuming that this is a Firefox issue, as the problem does not occur on other browsers

I can easily switch browsers and / or search engines, but Firefox in conjuction with Startpage is my preferred combo. I just find it frustrating in that I cannot fix it myself.

So....Ehhhh...what's up doc?

I can’t seem to open any Word files in Firefox. Doesn’t matter if it’s a new file or an old one, it just won’t open. What’s weird is that it takes me to a OneDrive page saying the file doesn’t exist or isn’t available. But when I switch to Google Chrome, everything works fine.

On nytimes.com some page elements are missing like pictures. the onepiecedle page just displays the background.

In Pic1 you can see what the page is supposed to look like, here opened in chrome

In Pic 2 you can see what it looks like in Firefox 126

I tested troubleshoot mode, private window, etp off, private window, hardware accel. on/off, nothing seems to work.
