I'm trying to watch videos in Firefox. Youtube works but Xvideos does not. Firefox pops up a window asking me:

>> "Opening xvideos"."com ###.mp4". >> which is: MP4 Video (16.4MB) >> from https://cdn77-vid.xvideos-cdn"."com >> >> What should Firefox do with this file?

My only choice is: Open with Windows Media Player x86 (default)

suggestions?

I'm running Windows 7 Firefox 76.0.1

Thanks!!!!

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

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?

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

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.

I live with Firefix always in full screen. I Don't like seeing any bars or buttons of any kind.

Befor the latest update, when I moved my mouse to the top of the screen my tabs popped down and in the top right corner was the standard icons for "minimize" "maximize" and "exit".

With the latest update the tabs are there but the 3 buttons have gone.

If I exit full screen (F11) then they are there again, but I dont want to have to exit full screen every time I change between programes which I do every few mins. I'd be popping pages in and out of full screen every few mins!

How do I get the buttons back all the time?

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 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.

I was quite unhappy with the new Firefox Proton design, so I made a CSS file and copied the following code from a website. However, I don't know what to do to (1) slightly reduce the tab height, (2) get back tab borders for inactive tabs and (3) remove the small gaps between tabs. How exactly do I have to change the following code to do so (ideally, for convenience, please just complete the code accordingly)? Thanks in advance for any support!

/*** Tighten up drop-down/context/popup menu spacing (8 Sep 2021) ***/

  min-height: unset !important; /* v92.0 - for padding below 4px */

    margin: 0px max(calc(var(--user-tab-rounding) - 3px), 0px) !important;
}

With the new v85 of Firefox... for Microsoft Print to PDF...

the defaults for print headers & footers has changed and is no longer available to edit or even view. It seems as though my settings remain in place for other printing options like my physical printer but even there the options are not editable or viewable.

There used to be a "page setup" option but I have not be able to find this anywhere anymore.

I'm assuming that it has to do with the bug fix for pdf printing but doesn't seem that it should be an intended outcome of the fix.

Any work arounds anyone knows about or has found?

I don't know if it is a wrong manipulation or an update feature, but since today when i select a link in the history library, it is now highlighted with big yellow dotted borders instead of the usual subtle black/white single pixel sized dots. How to revert back to the small borders?

I always used Mozilla to access my yahoo account. From their was a tab for my yahoo email accounts. What do I do now as there is not tool bar or email tabs. How do I access my yahoo email addresses???

I have noticed recently that every week or so my Firefox browser will randomly change my homepage directory to the landing page / search for MSN, which is baffling, since it is obtrusive and anti-Mozilla to me.

If y'all are sneaking it in for that sweet ad revenue, I understand, but I would donate to avoid this issue.

Otherwise Firefox / Thunderbird are awesome, and I appreciate all that you do!

Cheers, Elliot

Updating to version 98.0 onwards Firefox has started saving a copy of every pdf file I view (open) in my downloads folder.

My settings have not changed:

Tools->Settings->General->Applications: - pdf (application/download): Always ask - pdf (application/force-download): Always ask - pdf (application/pdf): Use Adobe Acrobat DC - pdf (application/x-download): Always ask

And when the "ask" dialog pops up, I choose "open".

I have tried all standard methods/troubleshooting, including resetting the handlers.json file.

The only way to avoid getting a copy in the downloads folder is if I choose "Open in Firefox" (application/pdf) instead of "Use Adobe Acrobat DC".

Any solution to this?

Thanks Michael
