Diễn đàn hỗ trợ Firefox

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

Edition Windows 10 Home Version 21H2 Installed on ‎09-‎Jun-‎20 OS build 19044.1466 Experience Windows Feature Experience Pack 120.2212.3920.0

Firefox: 97.0 (64-bit)

Tried to reset settings. Does not work. Went to about:config, than tab.mo / print.tab_modal.enabled set to false. Did this method before and it worked. Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

Hi, how do we set Firefox 97 to use the os/system print dialog?

Before Firefox 97 we could change these settings in about:config:

print.tab_modal.enabled = false widget.use-xdg-desktop-portal = true

But they are both gone now.

There is now widget.use-xdg-desktop-portal.print, which is an integer (2 by default).

But no matter what integer it is set to, we still don't get the os/system print dialog.

We are using Arch Linux, but we don't expect that to be of any importance -- after all, it worked before Firefox 97.

Thanks for your time :o)

I just updated from Firefox 96.0.3 to Firefox 97. When I try to print I get the Firefox preview, even though I have print.tab_modal.enabled set to false. Please fix it so that I can get the print system dialog without going via the Firefox preview. Note that I have now reverted to Firefox 96.0.3 and won't update from this unless the problem is fixed.

Firefox 97 installed itself , and now I have two print dialogs each time I go to print something. I have the system print dialog , and the Firefox print dialog. Does anyone one know a way to turn of the Firefox dialog in 97?

I fixed it in earlier versions by setting

print.tab_modal.enabled = false

...but in Firefox 97 it seems this no longer does the job.

Grateful for any advice.

I have always had the Print UI disabled by setting print.tab_modal.enabled to FALSE. Since the Version 97 update today, this is not working. The FALSE setting is still there under about:config but the Print UI dialogue now keeps coming up.

Prior to FF97 a simply setting to "false" the about:config, print.tab_modal.enabled setting allowed FF to always use the system dialog box when printing. However, in FF97, this is no longer the case. How can I set FF97 to always use the system print dialog box??

I almost always use Preview printing on my Macs to avoid multiple pages of garbage so this is fairly important to me...and it might help to save a few trees...

How can I restore my old system print dialog window as my default, instead of getting the horrible new print window that now appears? I have already set both the print.tab_modal.enabled preference and the app.normandy.startupRolloutPrefs.print.tab_modal.enabled preference to FALSE. This did NOT solve the problem! I knew updating Firefox to version 97 would be a huge mistake, and of course it was. I'm so irritated...

I'm using Windows 10 Professional. Any help greatly appreciated.

Firefox automatically updated last night, and once again defaults to its own printer dialog box. I hate it. There is a link to use the system print dialog box but it only works for that specific print job -- which wastes a lot of time every time I want to print.

I can't find a setting to choose my system printer dialog box as default. the solutions from last year no longer work (about:config, then tab_mo, then print.tab_modal.enabled, set to false.

Anyone know how to fix this? It's enough to make me stop using the browser because the Firefox dialog box sucks.

In Settings/Applications, have "JNLP file" set to "Use Java(TM) Web Launcher (default)". This is used in Oracle's Agile to view documents. In previous versions of Firefox when selected, the file would open using Java to display the document from Agile. As of Firefox 97, now only "Save File" or "Cancel" options are offered. What happened that this functionality has been removed?

I use to be able to change firefox icons by adding these files in Firefox under the browser directory

chrome/icons/default/BrowserPreferences.ico chrome/icons/default/CustomizeToolbarWindow.ico chrome/icons/default/default.ico chrome/icons/default/downloadManager.ico chrome/icons/default/main-window.ico chrome/icons/default/openLocation.ico chrome/icons/default/places.ico chrome/icons/default/printPageSetupDialog.ico chrome/icons/default/TabMIxPreferences.ico chrome/icons/default/unknownContentType.ico chrome/icons/default/viewSource.ico chrome/icons/default/Wizard.ico

It worked in version 56 but now in version 97 and this no longer works?

Hello,

the newest update to version 97.0 was run automatically. Afterwards the new print preview appears although I have it disabeled in about:config (print.tab_modal.enabled --> false). I cannot get rid of it. It is very annoying as I cannot print my labels with that menu and always have to click once more to do so. Does anyone has a fix for this?

Thanks in advance,

Thomas

Hey folks, hopefully you can help with this mysterious issue!

I've been running Firefox successfully on my Windows 10 PC for a long while now. Last night, for some reason it simply ceased to work. New windows and tabs would not load any content. I also couldn't access the Settings at all (clicking on Settings in the browser menu produces no results or feedback.)

Yesterday, I had Firefox open all day (I usually have my computer on all day), and it was working fine. Around 8 or 9pm, I first noticed that none of my open tabs were loading any content, and the tabs had the "loading" animation playing. New tabs would also not load any content. I assumed it was an internet issue as I did see my internet connection get disrupted once or twice. I did not see anything (apps, etc) on my PC updating.

This morning I found Firefox was still not loading anything, although my internet connection was fine. I tried opening Chrome, and it ran just fine. Everything else that it is internet or cloud based on my PC is running fine too. So it seems to be an issue just with Firefox.

I have listed my steps to troubleshoot below, but I want to note one weird thing I observed: Even when Firefox is closed, and Task Manager doesn't show any Firefox processes open, my PC seems to think Firefox is running. For ex. while trying to uninstall Firefox or delete certain files, I would get a warning to "close Firefox first" or "can't perform this action while app is running." After seeing these, I would again confirm that Firefox appears closed and Task Manager shows no related tasks.

My PC build: - Windows 10 Home, 64 bit - Version 20H2 at start of issue (updated to 21H2 during troubleshooting) - OS build: 19044.1526

Things I have tried for troubleshooting already: - I have WebRoot on my computer due to my job, and I asked our IT staff if they could see WebRoot blocking anything related to Firefox on their end. They said it was not. - Used "Firefox Refresh" - Uninstalled and reinstalled Firefox - Cleared app cache / app data - Updated Windows from 20H2 to 21H2

Note: This message was sent on a different computer & browser

Cannot get out of the terrible firefox print dialog. Literally no one wants this print dialog, it is a waste of time, and does not support all the printer options. I do not want to have to click "print using the system dialog" every time. Please restore the print.tab_modal.enabled = false functionality immediately. Or better yet get rid of your stupid print dialog.

thanks

In the last Firefox update, you changed the printing user interface AGAIN. The print.tab_modal.enabled=false config option no longer works, and I can't easily re-scale my page when I print. Is there a new option which restores the original behavior or is there some other remedy that will let me print using the Windows System dialogue?

When I display the review page for any installed add-on, I'm unable to submit a review. A few details:

1) I do not see the expected, "Rate Your Experience" link 2) I'm logged onto my Firefox account 3) I'm aware it uses different credentials than Mozilla Support 4) I've tried clicking on the yellow stars but it doesn't allow me to rate the plug in or display any new links 5) I've read other forum posts from other users who've experienced the same symptoms

Ideas, anyone? Thanks,

Hi all, due to the occurring problem I cannot select topic to describe best my type of question:

Description of fault: Using Open Suse Leap current version 15.3 (KDE) with all patches installed (zypper dup: no action required) In either thunderbird and firefox application (but e.g. not in dolphin or k3b or gimp...) I have following problem: When pressing any entry in File ... View... bar I do not get a visible dropdown menu to chose from Firefox specific: When I try to use a bookmark folder in the bookmark bar there is no visible dropdown menu to chose from When I try to chose from a dropdown menu inside the content of a web site i will get no visible feedback at all.

BUT: when I want to chose a bookmark that should appear in a dropdown list and I move the mouse to that remembered position I see in the lower left corner the bookmark's address and I can chose it! The same happens with the dropdown menus from the the File.... View... Help line. I am able to chose a command once I remember where to point to.

So I guess all what is missing is the overlay plane where the menu contents reside.

This problem occurs in 95% of the time I use both applications, BUT there are 5% of the time where everything works like a charm. I have no idea what i do differently in that usage. Whenever Firefox works normal, also thunderbird does. Is it somehow a KDE releated problem?

How can I fix that problem? Any hints?

Thank you

Johannes

I'm hiding menu items using userChrome.css with option “toolkit.legacyUserProfileCustomizations.stylesheets” set to “true”.

So I am hiding some menu items like for example

1. menu_find { display: none !important }

however though the menu item is gone how do I get rid of the ctrl-F menu shortcut...

I have many such menu items to remove so I need a generic solution to override the short-cut icons associated with the menu items I want to remove
