For a few days now, I have not been able to play videos. I get this message in the video screen: "If playback doesn’t begin shortly, try restarting your device." When I opened Firefox in Troubleshooting mode, the video played OK and then when I stopped Troubleshooting mode the videos continued to play OK. However, on the next day the problem reappears. What's going on? Thanks in anticipation, Frank

FireFox Developer 99.0b8 (64-bit) on the "aurora update channel" on Windows 10 PC (version 1803, build 17134.2208)

I notice whenever an update is pending (the green dot appears in the icon for the "Open Application Menu"), FF becomes unresponsive in a way. When it happens: It does not totally freeze. I can select/switch between existing tabs & scroll thru their pages. I can close tabs. I can open a new empty tab. But I can't load or refresh any pages. The only fix is to do the update, and re-launch.

Since the developer edition gets updated frequently, it is a pain.

I like the Developer Tools! But... How can I scale back the FF "update frequency", or "change the channel", so updates are, like monthly at most?

thank you.

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

I'm struggling to get Firefox to use `http` instead of `https` when I'm doing development on my laptop. Playing with the `HTTPS-only` in the settings didn't make difference. With enable or not. I tried to add my `localhost` to exception list, but Firefox still tries to use `https.`

I understand the security concern from Firefox team, but if I'm trying to load by typing `http,` I would appreciate if Firefox gave me a benefit of doubt that I know what I'm doing. Maybe I could disable this feature temporarily. Why force `https` on `localhost`?

Please allow us some flexibility.

Hello,

Before the release of Firefox 99, the drag and drop function of e-mail using OWA (Microsoft Outlook) stopped working. In the last version of 99, it started working again (and I was very happy). My browser just updated to 100 and it stopped working again (and, of course, Firefox recommends not downgrading).

This is getting very frustrating, as I use Firefox at work and it is actually a lot of time wasted, going in and attaching files without drag and drop. I am on the verge of abandoning Firefox as my browser, since these features work in both Safari and Chrome. However, I do like the usability and security of Firefox, so I am hoping you can fix this very soon.

I am wondering if it is at all possible to adjust the settings when pulling a tab into a new window. For example, if I am running Firefox fullscreen I would like the tab that I pull to be opened in windowed form. I noticed that this is typically the case when using Chromium-based browsers, but noticed that on Firefox it stays in the format as the previous window. (if already windowed the pulled tab will also be windowed) is there a way to ensure that the pulled tab will always be windowed?

Good day.

My use case is the following. I use Firefox Developer Edition for developing websites. Usually the development happens on a certain part of the page. Most of the times it is not on the top of the page, so you have to scroll down to it.

Sometimes when the page is refreshed a jump to the top happens. So then I need to scroll down again. It takes a lot of time and concentration away if it happens dozens of times a day.

It often happens after I did some changes to the files on the page. It usually does not happen when I refresh the page a couple of times (when I purpously want to reproduce this problem).

I did try running Firefox in Safe mode, but it didn't help.

What can be done to fix this problem on my side? Is this a bug in Firefox itself?

1. Sites www.applevacations.com / www.cheapcaribbean.com fail to display a city.

2. in the ipfire firewall console, FF doesn't render graphs correctly.

I'm not sure when these broke.

FF 101.0 (64-bit).

Pictures are of FF vs Chrome chrome and MS Edge also work correctly. the 2 pics with more graphs are the same pages @ %50 size.

Hi,

Its about time you looked at your Mic cam Cam settings

I'm getting older, they should be set as on as Default, and switched to off if required

This is a massive issue to a great part of the community I don't use Firefox as I used to, as so many of my clients are also moving away, ( Gone to different platforms to Edge and Chrome) I'm sure this can be easily fixed.

Since earlier this week my Firefox browser has been turning .jar files from GitLab into .jar.zip files, which prevents them from being used properly until renamed. Attempting to download the same files on Edge or Chrome works correctly, and attempting to download any jar files from other websites (even GitHub) also works correctly. It seems that GitLab is the only website that is affected by this.

Examples of files being affected (they should be downloaded as normal .jar files): 1. https://gitlab.com/Trafalcraft/antiRedstoneClock/uploads/3b3c84814d76810f826c3803eaca1e66/antiRedstoneClock-1.4.1.jar 2. https://gitlab.com/Aristois/ui-installer/-/jobs/2505715157/artifacts/raw/packager/Aristois-Free.jar 3. https://gitlab.com/Aristois/Installer/-/jobs/2495195255/artifacts/raw/packager/free/Installer-2.0.3.jar

I'm using Firefox developer edition (102.0b3), and already tried using private mode, resetting Firefox, and reinstalling. Since I use GitLab as a main source to upload files, many users have also complained the same problem to me, in which all of the users were running Firefox. After they downloaded with a different browser, it worked for them as well.

I have been seaching for the solution for the whole day, and i found the closest one. It Does remove tabs, windows buttoms, but the background bar still remains, and i dont need it this way. So thats the code i used to make it >>>>>

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

1. main-window:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

} /* This makes the bar shorter vertically but removes the 3 window buttons */

1. main-window #TabsToolbar {

 visibility: collapse !important;

} /* For full screen mode */

1. TabsToolbar[inFullscreen]{

 display: none !important; 

}

On the screenshot you can see what remains on tabs' bar place I need my browser to end just above the URL string, so there wont be empty space in the top of the monitor. Can you help me find solution for this problem, please?

MacOS FF dev edition 102: I have a folder in my bookmarks toolbar, and I frequently open all of them in tabs. But that option is missing from the context menu on the folder. It is there at the bottom of the folder if I click to open the folder, but this is silly. There is an "open all bookmarks" context menu option on the folder, but that opens all the bookmarks in the toolbar, not in that one folder. why is this?

I'm running Firefox Dev edition and I cannot get it to load any pages except for Mozilla pages. I have tried all the fixes suggested there and it still refuses to connect. I'm at my wits end. Any hail mary optoins or do I have to reinstall and start again?

Long story short: windows update sneaked a restart under my nose caused me to lose all my previous session.

I'm attempting to recover the previous session.

I have backed up the unmodified session profile folder. But this profile folder was modified by the restart process obviously, as windows gave firefox "normal shutdown" command. How do I know that? The next time I opened it up, it's "brand new" without the "restore session" interface.

So my idea is to figure out if firefox keeps a track record of previous sessions EVEN IF THE SHUTDOWN WAS PROPER.

If it does, well I'll have to figure out a way to "trick" firefox to restore it. If it doesn't, well I'll have to manually restore it by sifting through the history.

I repeat, the key here is for me to find out whether or not firefox always keep a record of previous session somewhere.

So my question is, does it? Or does it purge all the previous session clean as long as the shutdown was deemed "correct"?

I am attempting to build a script (extension) that will open any focused page in Firefox with Microsoft Edge from the context menu. The intention is to utilise the existing microsoft-edge URL Protocol in Windows instead of a native client.

Firefox prioritizes IPv6 (even on a network with internet-accessible fd00:: address, which contradicts my currently set up prefix policies) over IPv4. Now the problem is that my IPv6 address is a tunnelbroker.net one, and while I still want to be able to access the IPv6 internet, I don't want a tunneled connection to be my default. And I don't want to disable IPv6 completely. Is there a way to force Firefox to prioritize IPv4 over IPv6?

Note: the first time when connecting to a website, the browser connects via IPv4 (like the prefix policies are supposed to work), but then it remembers that the website is accessible via IPv6, saves it into the content-prefs.sqlite file (removing the said file makes the connection fall back to IPv4 first again) and connects via IPv6 again. Is there a way to make Firefox NOT remember that in content-prefs.sqlite and still connect abiding the prefix policies?

Using Firefox Dev Edition 103.0b9 on Windows 11 x64

1. When I create a sign on for a new web site Firefox is no longer saving and auto filling the logon credentials. 2. Now when I load a website logon screen it is not always auto filling the stored credentials. Instead of auto filling now I must click on a displayed use rid to get the use rid field filled. I then have to click on the password credential to get the password auto filled.

Trying to reinstall a working module that I deleted, but now it only displays the title. And none of the code works.

Why is part of the code greyed out in Firefox developers.

Last few days any Firefox 102.0.1.8221 launch causes my Windows 7 64bit to reboot, usually when I try to mouse click anything in Firefox after it's fired up and restored open tabs, however even if I don't mouse click anything Firefox will force a reboot within a minute or so.

This Firefox Win 7 reboot behaviour only started after the last Firefox update, though I would point out that around update version 100.nn I started getting failed update notifications from within Firefox which necessitated a manual newer version Firefox download and install.

Running Windows 7 in safe mode with networking on allows Firefox to function without crashing, albeit slowly and with no MSE protection available etc.

Only one crash report dated 16/07/2022 with following content: Crash ID: bp-d8383165-9c77-45e4-9929-a3ce12160527

Please note I'm sending this report via Firefox on my iMac coz that still works...
