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?

So I just updated to version 106.0.1, and I noticed something new in the far right corner of the screen, an arrow with a dropdown function listed as view all tabs. I have no need for this and tried to use the customize toolbar option to remove it. It did not work. How do I get rid of this thing? It's just kinda taking up space on the screen as I doubt I'm ever gonna use it.

Any tips here?

Hey all, I just updated Firefox on PC and the updater asked a couple questions. I chose "Visionary" as the answer to a question because it suited me the best out of all the options. However, this also changed the colors of my browser menu and toolbar to green. The thing is, while green is a fine color, I would never select it as "my" color for anything ever.

I've tried to change the color in about:preferences, but nothing I can find seems to work. Any ideas?

Thanks!

Hi, I am using the dark mode in firefox which is god sent boon to persons having glaucoma, with dark mode in firefox and dark reader add on. This was going well and after a recent update, I could not find it working. The dark mode is enabled and dark reader was there, but the browsing pages only shows in white. Has firefox changed anything recently to have this issue? If I miss something would the experts say, how to get back my dark browsing experience in all sites. If I find anything not visible in some sites, I used to go the windows properties and change the contrast theme to windows basic blue theme and then switched back to dark theme. this was helping the glaucoma persons very much. please, say how to solve this problem

Hi, everyone. My multirow bookmarks no longer seem to work since my latest update to 107.0 (64 bit). My computer crashed and when it came back up Firefox no longer worked. I reinstalled it and have a bit of cleanup to do, but everything works now except my faithful (up-to-now) multirow toolbar. Here's the code in my userChrome.css file.

/* Multi-Row Bookmarks Toolbar */

1. PersonalToolbar {

 /* Override max-height */
 min-height: unset !important;
 max-height: unset !important; */

}

1. PlacesToolbar > hbox:first-child {

   display: block

}

1. PlacesToolbarItems {

   display: flex;
   flex-wrap: wrap

}

Previously, this was in my profile folder. If I move this out of the profile folder, my browser works fine but there is no multi-row toolbar. If I put it back into the profile folder, I have a multi-row toolbar, but no contentd in the main window.

I am perplexed. Help? --elizabeth

Firefox has arranged my extensions alphabetically. I would prefer to group them functionally, or at least be able to separate those which have similar colors -- for example, Grammarly and Evernote are both green and I sometimes click on one when I want the other. I would also like to have the one I use most at the far right of the toolbar.

I'm using Firefox 85.0.2 . . . I was doing this (below), to customize my header and footer, but in this version of FF, I no longer see this in Options - only in: about:config . . . keyword "footer" . . . there, I would have to change it for 5 different ways of printing (to printers or to PDF)

I need to get rid of printing the URL in the footer - many times, it's too long, and I don't need it.

Where did the Page Setup option go?

I see in the current Print Options, you have to go to - More Settings / Margin / Custom - to see those. Why would they put this so many levels down?

It used to be: File / Page Setup / Margins & Header/Footer . . . "Customize" Headers & Footers:

Option 1 (left) . . . there are two leading spaces:

 > > &T
 > > &U . . . &D . . . &PT

Option 2 (left) . . . get rid of the ">"s, and just have the two leading spaces:

 &T
 &U . . . &D . . . &PT

After a forced update, firefox stopped giving the popup that lets you choose what to do with the file.

A temporary fix is to go into options and set "Always ask you where to save files", however this is clunky, and much much slower, so is there any way to get this popup back?

If not, then i will have to migrate to a different browser for safety, since this new "Feature" can be easily abused by hackers and malicious websites.

Firefox would not finishing loading so I (stupidly) clicked "refresh firefox" not realizing it would loose add-ons, extensions, etc. It created an Old Firefox Data folder if that can somehow get it back to as it was instead of having to figure what add-ons I had & reinstall everything, etc. My Bookmarks still appear but I need the add-ons back!

How to change the Tab color for inactive tabs?

I have a userChrome file and have been able to change the color of the active tab but cannot do so for the inactive tab. The inactive tab color blends into the toolbar color. If I move my mouse cursor over it changes to a slight darker gray color.

Active tab color. I made mine a off white color:

.tab-background[selected="true"] {

   background-color: #f9f7f1 !important;

}

Until yesterday everything I customized for Firefox 89 in June of 2021 and FF 91 in August of 2021 was working fine.

Today I updated to Firefox 96.0 and when I open my Firefox returned to that old visual that I hated

tabs with spaces , but that's not the worst. The worst is the newTab visual that came back to the small and ugly bookmarks of the page we usually navigate. That are set on userContent.css I remember.

I checked some vars at about:config and everything is as it was.

So do I need to set true or false any new var there? These .css files are like they was never read. It looks like to me there is a new var, we need to change it.

What did happen?

Thanks in advance.

I'd like to use the Startpage search as my default search in Firefox, instead of Google. And I mean the keyword-less search. I know what a search keyword is and I use several for special search engines (map, Wikipedia, dictionaries, parcel tracking, etc.). But the default search must work without any keywords.

And I want to use the custom settings they provide as URL parameters. I've tried with the cookie option but the cookie expires even after regular use. So the custom URL is the only working solution. Startpage support recommended me doing that.

I know that I can install the Startpage search to Firefox and it worked. But I can't combine it with the custom settings. So I uninstalled the extension, deleted the search engine and went to my custom startpage.com URL. Right-clicking the URL bar allowed me to add the search engine from there. But it also doesn't have my settings.

I couldn't find the search URL in about:config. Where is it stored? I need to change whatever Firefox thinks is Startpage's search URL to include my settings.

Changing the settings is critical because by default they open clicked results in a new tab which I cannot stand. I have enough open tabs, and there's still the back button.

Hello. I noticed that Firefox (98.0.2) doesn't even ask if the file should be saved or opened with a program when downloading some file types. Unfortunately, these file types (e.g. GPX) are not listed under Settings --> General --> Files and Applications, so that I could assign them to a program or specify that they should always be asked. And I can't add these files somehow... I have also deleted the file "handler.json" in the profile folder, hoping to be asked then. But that doesn't happen. GPX files, for example, are assigned to the GSAK program in the system - but Firefox just wants to save them and doesn't offer the option to open them directly in GSAK. Does anyone know advice how I can get Firefox to give me the choice? Thanks a lot.

I just updated to the latest version of Firefox, and all of a sudden I have a new icon, Extensions, that looks like a puzzle piece, I cant seem to be able to remove it....at all.

When I first go to the URL bar to either search or enter a URL I see a drop down of sites. These are not the search engines. See the image attached. How do I remove these?

according to the add-on page in Settings, the AdBlock Plus add-on is enabled in my browser, but it doesn't appear to be working. so I am trying to access the menu options to control it. to do that, I need to add the icon to my toolbar.

this article: https://support.mozilla.org/bm/questions/955157

explains two methods:

1. go to Settings --> Customize Toolbars, and drag the icon to the toolbar. this doesn't work, because the icon is not there to be dragged (even after I restore defaults).

2. go to the View Menu --> Toolbars --> Add-on Bar and move the icon from one toolbar to another.

quite apart from the fact that it took me two days to figure out how to get the View Menu to appear, that procedure doesn't work either because after View Menu --> Toolbars --> the Add-on Bar is not listed.

can someone please tell me what I'm doing wrong.

thank you,

In my opinion, App Mode is a very useful feature that allows installing a website as an app. However, I am unable to see any option related to App Mode in 95.0.2 (64-bit). Could you please help me about this issue?
