Firefox supportforum

Hello,

I deployed my NextJS app on Vercel, but I cannot access my deployed app through firefox because of HSTS.

I tried to access several sites with domain .vercel.app but the issue persists.

I can access all sites with ".vercel.app" domain just fine on other browsers except Mozilla Firefox.

I already looked for solution on the internet such as:

1. Removing entry on SiteSecurityServiceState.txt
2. Forget site
3. Clear browser cache & history
4. Restart browser

Any help will be appreciated.

Thank you for your time and attention.

as of 2023/09/29 hulu, netflix, prime and disney+ are not playing videos on firefox, after making zero changes to settings or configuration.

I tested Netflix on Google Chrome and videos played, confirming this is a Firefox issue. I cleared recent/all history and changed passwords for those sites. Netflix logs me out if I attempt to play content. Speedtest reports 200 mb/s. Mozilla VPN is installed but turned off. Netflix sign in reports a new device/login in my state which is different from the VPN setting so this confirms that the VPN is not active and blocking content. HBO/Max videos play correctly and that site does not have the same issues. Firefox has crashed numerous times in the last two weeks. Sometimes just a single tab, sometimes a full application insta-quit.

I prefer to compartmentalize usage across different browsers for privacy/security reasons and would like to continue to use Firefox for these streaming services.

I have found that Firefox does not play some audio files, for instance on Wikipedia and WaniKani, such as the audio on https://en.wikipedia.org/wiki/Erhu and https://www.wanikani.com/vocabulary/%E9%9F%B3. When inspecting network activity I can see that an attempt is made to load the audio on Wikipedia, but it does not play. On WaniKani however, no attempt is made. (WaniKani uses .webm for sound, maybe that has something to do with it?) The problem appeared after the update to Firefox 118 and persists in private browsing and troubleshooting mode, but does not occur in GNOME Web.

Hello! Since I updated Firefox to 118.0.1 (latest version when writing this) the Teams Large Gallery mode in Firefox is displaying black and eventually all the participants appear but the performance is 1 frame per minute. All the cameras are frozen and occasionally the display refreshes for one single frame.

Audio is working fine and default Gallery mode (only 4 camera displayed) still works normally.

Thank you!

Hello,

Recently Firefox tends to start autoplaying a YouTube video if I am on the tab.

Before it would not play the video if i am on the tab unless I physically press play.

It still works if I open a YouTube video in a tab that is not active, it will not autoplay, but as soon as I hover over and click on that tab it will start playing, however I do not want this to happen, I want it to pretty much always be autoplay blocked regardless if tab is active or not and I want to physically press play in order for it to start.

How to revert it to that state?

My block audio and video setting in firefox is already turned on, not sure what to do, pretty sure I did nothing on my end.

Right now I have to use extension called "disable autoplay" just to get by.

Thanks guys!

Hiya,

I use a theme which some years ago (after a change in the way Firefox handles dark-mode preferences) changed all UI and websites to use dark-mode. I was able to keep using the theme, and mostly override this behavior by setting:

`layout.css.prefers-color-scheme.content-override = 1`

However, this didn't take for some components, such as the sidebar and bookmark editor window, which still continue to use dark-mode.

Is there any way to completely disable dark-mode everywhere, and still use my preferred theme?

Cheers, Afraz

Since the latest download one of my 3 win10 PC's is displaying icons on top of the text. Firefox is up to date at Ver 118.0.1 (64-bit) I expect its a setting but I cannot find it. Screenshot attached. TIA KR's Andy B

Firefox has been closing at random times. I do not see any crash logs in Firefox or event logs in Windows as to why this is happening. I can immediately re-open and it picks back up right where I left off. I am on Windows 10 enterprise 2h22, running Firefox 118.0.1 64-bit (this has happened in previous versions as well). I do have some add-ons, Tabliss, Cookie Quick Manager, Dark Reader, Sidebery, Lastpass, and Firefox Multi-Account Containers. I have checked each of these and uninstalled all of them but still happens. I have also uninstalled and re-installed and I am stumped. (I also have this same set up running on another computer but it has never done this to me)

Any ideas on what else I can try? Or other ways to investigate what is happening?

Using Ubuntu 22.04. I can upload and download files from /tmp and also from any directory on the home partition (or symlinked entirely within the home partition). However, I have a data partition with symlinks in the home partition, and Firefox throws a permissions error when I try to read or write from or write to one of those symlinked directories. So far, Firefox is the only app that exhibits this behavior.

I believe I need to change the "Security Context" in Firefox, but I haven't been able to figure out how to do that.

I describe the problem more fully here:

https://askubuntu.com/questions/1487763/firefox-cant-read-or-write-to-directories-symlinked-across-partitions

I will have to abandon Firefox if I can't fix this.

Thanks!

My Firefox 118.0.1 on Win 10 (all current updates) is creating literally thousands of profile files daily. For example, at this moment there are 3957 profile files with names like

6D89348819C8881868053197CA0754F36784B4BFSF

in the directory C:\Users\(user)\AppData\Local\Mozilla\Firefox\Profiles\ywlawdlc.default-release-2\cache2\entries

There are also thousands of other profile files in folders from previous dates.

What is the purpose of this many profile files, and how do I stop their creation in such quantities?

Thanks Dave

Hi,

I am using Linux Mint 20.3, 64-bit and both Firefox and Chrome are not loading images for me on certain websites (i.e. okcupid). In particular, I am noticing that images will actually load for a split second and then disappear moments later.

I've tried disabling my adblockers, deleting my cookies and cache, running Firefox in Troubleshoot and Diagnose mode, running Chrome in Incognito mode, and evening uninstalling and reinstalling Firefox. Still the issue persists.

I followed the advice here: https://support.mozilla.org/en-US/kb/fi ... s-not-show

Any advice or suggestions would be most welcome.

Thanks, Chris

Suddenly my "find in page" or "Ctrl F" function from the Firefox menu doesn't work. I can click on it but nothing happens. I never get a place to type in what I want to find. Did I accidentally change something in my Settings? If so, I can't find what it was.The same function in Chrome still works just fine. Please help. Thank you.

A few months ago, an automatic feature in bookmarks quit working. It used to be that when you bookmarked a page you would be prompted about what bookmarks folder you wanted to put it in. That suddenly quit working. Now, after you bookmark a page, you have to go into "Manage Bookmarks" then move it to the folder you want. I can't find a setting that would bring that back. Was this a change that was deliberately made in an update or is it just a glitch that happened somewhere along the line? If that feature was removed, I'd like to know why. It doesn't make sense.

Is it possible to spell check the entire web page using both Hunspell built-in dictionaries and user-defined dictionaries *.dic, already prepared text in Firefox. As it is done in text editors like Libre Office (also uses Hunspell) but for web site, checking the text from top to bottom with errors in a separate window, so spell check is not only in the text input/search field.

Mouse is Logitech MX Master 3 for business. When I scroll on Maps to zoom out or in, it zooms all the way out or in, even when I just do one "scroll click". Scrolling up and down works fine on other websites. Using the scroll wheel for zoom in Google Maps in other browsers (latest versions of Google Chrome, MS Edge, Brave) works as expected/fine, there it only zooms out/in one level.

It's not a new issue, it's been here for a long time, I just haven't bothered doing anything about it.

I have found another old thread about the same issue and the suggestion was to disable hardware accelleration. I tried that and it made the scrolling worse, but same thing happens, just slower and with choppiness. I have tried running troubleshooting mode. Still the same thing.

Using 118.0.1 (64-bit) under Linux Mint 21.2.

Apparent bug: Retrying failed "Web Page, Complete" case of "Save Page As..." does not retry downloading files.

1. Observed behavior:

1. With the extension "DuckDuckGo Privacy Essentials" enabled, typically if I do "Save Page As..." and choose "Web Page, Complete", then one or more files in the resulting "... Files" folder is missing compared to if the extension is disabled. This is probably as it should be. But...

2. In the downloads dropdown the download is shown as "failed". This is arguably as it should be, though the lack of information as to exactly which file download failed is unhelpful. Or arguably it is not as it should be, since from the point of the privacy extension user the download did not fail, it succeeded completely. But...

3. ***If I then click on the retry icon, it re-downloads *only the HTML*, not the files folder, and reports success.***

1. Expected behavior:

If a "Save As..." "Web Page, Complete" fails, then retry should attempt to re-download all the files, or at least all the ones thought to have failed.

On my own computer, a Dell laptop running Windows 10, my Firefox 118 is customized to my satisfaction. In particular, in the upper right, from right to left, there are five icons: three lines for accessing a Firefox functions menu, a "puzzle piece" icon for accessing add-ons, a U-Block Origin icon for that ad blocker, a set of vertical lines that let me access some bookmarks and history settings, and a star that, when clicked, displays my whole bookmarks menu tree, showing a combination of individual URLs and URL folders that I saved there.

    Now I am trying to set up a new Dell laptop the same way. It's running Windows 11, and I cannot find a way to display that Firefox menu star. It's got the other star (the "save to favorites" star, farther to the left), but I cannot find a way to display that "show me my bookmarks" star. How do I get that icon to display?
