Firefox Support Forum

Hi everyone,

I am having trouble getting my custom new tab page to be focused when opened (instead of the address bar).

I am currently using the `autoconfig.js` + `mozilla.cfg` approach to overriding the `AboutNewTab.jsm` service with a custom local file. This is working great with the two files containing this code:

autoconfig.js: ``` pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0); ```

mozilla.cfg: ``` // Custom firefox config

let { classes:Cc, interfaces:Ci, utils:Cu } = Components;

try {

 Cu.import("resource:///modules/AboutNewTab.jsm");
 let newTabURL = "file:///home/vallode/Documents/test/index.html";
 AboutNewTab.newTabURL = newTabURL;

} catch(e) { Cu.reportError(e); } ```

I have been attempting to use the `gBrowser` global to add an event listener to the new tab opening, but with no success. Could anyone point me in the right direction for something like this?

Hello,

Since about 3 weeks, Firefox hang on certain websites while trying to load them, when un-ticking all "Firefox Home Content" items. When those things are ticked, everything is fine. Wasn't happening before. Often a gray geared wheel appear and at other times only the "tab text" appear, please see the attached screen shot. I'm able to click on "File Edit View...", the items present on the bookmark toolbar, "Refresh", "Home" but the action is executed only when Firefox un-hang. I'd already get a look at Firefox help tutorials but there was nothing about "The "Firefox Home Content" can cause Firefox to hang".

It take me about 10 minutes to load this current page. "Firefox Home Content" are not ticked right now.

Thanks,

Guillaume

hi all, i try to import all passwords from vivaldi to firefox 78.0.2 but looks like there is completely no option to do that. the only export option is when i open import wizard which tells me "no programs that contain bookmarks...could be found" which is complete nonsense as i have a vivaldi running and full of passwords. please do not advise me to put manually every password,i have close to 100,coze this will not happened. btw,im on latest manjaro xfce,just fyi if its important. thx for help in advance.

I use openbox as my windowmanager with NO desktop environment on Archlinux.

I want to hide the titlebar (border) but when using openbox this option is NOT SHOWN. It is shown when i use another Desktop Environment like xfce4 or Gnome.

In the past i found out that a variable like DESKTOP_ENVIRONMENT, DE or XDG_SESSION_DESKTOP could be set with the value of another Desktop Environment to mislead Firefox.

However, i can't find the right variable any more and i have been googling and googling for days :-(

Please help, i like openbox & firefox (without titlebar)

Not sure what the right place for this is; I wasn't able to find a Firefox support forum specifically for web developers. If anybody knows of a more appropriate forum, please let me know.

I'm trying to intercept the opening of a popup window from JavaScript, but I can't find any way to trigger the debugger on this condition, and I don't want to set the breakpoint manually because the source I'm working with is obfuscated and it would take a lot of work to track it down manually. I currently have Firefox 68 ESR, but I could upgrade if needed. Does any version of Firefox have a way to set a breakpoint on new tabs/windows opened from JavaScript, or is there a way to break on the `window.open` function which I suppose is what is being used?

Firefox will periodically broken at any time of day, in the middle of a work emergency, because it performed an update in the background. I am *not* looking to disable updates, which is all I can find information on. I still want the ability to install them when they're available or when I start or exit firefox, or whenever it might be. But I need to be able to have control the "feature" of Firefox just randomly and unpredictably crashing during the workday. How do I disable or workaround this feature?

Hello

There is a facility on the new (about 2 years old) BBC sounds "my sounds" app that Firefox is unable to use. The facility is known either as "remember where you are on a programme" or "pick up where you left off on a programme" I am using a Linux PC and a Windows desktop with the same problem on both.

I have checked with the BBC and confirmed that I have the correct settings and cookies enabled, which I am able to change through Firefox, but Firefox can't store how many minutes in I am on a programme, although it can access the same information when that is stored by Internet Explorer. In other words if I listen for 10 minutes to a particular programme on Internet Explorer, then stop and find it on Firefox, Firefox always goes back to that 10 minute spot, no matter how much further I listen. I am in contact with the BBC about this too.

I am running with firefox 79.0 and am using ubuntu 18.04

I have been using google hangouts for some time with no problems but, now, it will no longer work. It tells me that I have a problem with my camera/video and to check my network. My network is dandy. The only thing I could think of is that its a firefox problem. To check that I brought up google chrome and tried hangouts there and it worked just fine.

I have searched for a solution and found none although there has been an ongoing problem with hangouts for some time.. I suspect that some of the stuff that has been added to firefox to be the culprit but am not sure - hence this.

If anybody has a clue please let me know - thank you!

I am trying to emulate the expected behavior I have from Chromium based browsers. I want my two email accounts to open on startup but then when I open a new window, for just the blank tab to open (Firefox home). There doesn't seem to be a way to do that. I can make them my "home" pages so that they load on startup, but then when I open a new window, it opens both of my home pages as tabs in that new window. Any help? See attached screenshot, is there something I'm missing or is this behavior just not possible in Firefox?

I think Firefox has blocked my access to my hotmail account.

When I put this into my URL: outlook.live.com

it goes to main page - OK

But when I put this into my URL: outlook.live.com/mail

I get a blank screen . . . and the security icon to the near left of the padlock on browser does not have an option to unblock my mail.

I find no help at hotmail/msn. But my daughter used her phone and got into my mail there - so I think it might be my security setting on Firefox.

Any help will be appreciated.

Firefox 79(64bit) - two problems - may be connected

After two recent updates on Fedora 32 I notice that saving/downloading a webpage does not work properly. Sometimes the *.html file is there but the support folder is empty. Sometimes just the empty folder.

I have also noticed a problem when trying to backup .mp3 files from my Nexus tablet using File Transfer. I used to be able to connect via USB from Desktop to tablet, transfer from and delete files on the tablet using the Desktop. Now the folder holding the files is reported as empty.

Local files on computer won't open(just load forever). Tried pdf and html files. No problem with remote(online) files. Chromium works as supposed to.

Firefox 79.0 (64-bit). OS: Manjaro Linux KDE5.

Pas d'image vidéo avec facebook depuis la version 79 et 80 firefox.

Aussi pas de son lorsque je s'intonise la radio de www.radio-canada.ca

Avec chrome ça fonctionne bien

Firefox refuses to visit https://discordapp.com, complaining about SEC_ERROR_UNKNOWN_ISSUER. Upon inspection of the certificates, the root CA is "COMODO ECC Certification Authority" - Serial Number 16:E5:86:78:E0:70:94:39:4B:DF:DB:4E:FC:A6:3B:DF.

The Firefox certificate manager contains a trusted entry for "COMODO ECC Certification Authority", however it is a different cert with serial number 1F:47:AF:AA:62:00:70:50:54:4C:01:9E:9B:63:99:2A.

I'm wondering what's the cause of this situation? Did Comodo recently change certificates? Can somebody else check which version of the "COMODO ECC Certification Authority" is shipped with their FF?

Chinese Characters displays strange (some characters are extremely large) on Manjaro, and it will make Edge and Firefox on Windows display strange too.

There is a fullscreen mode that prints a window over the full size of the screen without showing toolbars/navigation/extensions... Is there a "full window" mode that do the same, but over the full size of a window? It would be a simple webview in a system window but without the control toolbars. It would be very useful when tiling several Firefox windows without wasting space for toolbars/tabs... This mode should be specific for a window since I do not want to loose the controls on the main screen-wide window.
