Firefox Support Forum

I need to continue to use an application (Web Site) built with Flash Player for the first 3 months of 2021. Flash Player support ends on December 31st 2020. What is the plan at Mozilla in terms of restricting access to Flash Player in 2021? - For example, is there a timebomb in the browser so that Flash Player will seize to work on December 31st? - If not, would Flash Player become inaccessible following the first browser update in 2021? If yes, do we know when date is scheduled for approximately? - Will the behavior be the same for all Firefox versions (Light, Enterprise, iOS, Android, etc..). Thank you!

FFox 92 update today. Menu spacing went to double. No shock there. Found the CSS code below for UserChrome.css and set it up.

EX.

menupopup > menuitem, menupopup > menu {
  padding-block: 4px !important;
}
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;
}

EX:

menupopup > menuitem, menupopup > menu {
  padding-block: 0px !important;
}
:root {
  --arrowpanel-menuitem-padding: 0px 0px !important;
}

But, it doesn't get any smaller than the above 4/8px set up. Bug? Perhaps there's another CSS setting to be tweaked for V 92? I do not have any other CSS for these items elsewhere in my UserChrome file.

The ability to edit and customize the headers and footers for printing was one of my main reasons for switching from Chrome to Firefox. Now I can't find where to do this. I don't know if it was a recent update or what but I am using Windows 10 Home. Please help so I don't have to find a new browser.

Posting on behalf of a user who hit the VPN inbound queue with a question better suited for this forum:

The tab bar, toolbar, and address bar placement in my Firefox Desktop browser has recently changed. I have been trying to revert these recent changes as they interrupt my current workflows.

I DO know which prior profile save contains the desired info however, it contains many files and I DO NOT KNOW which files I need for the bars to be restored. If you could provide me the name(s) of the file(s) that holds the bars data, I am probably saved, hopefully saved.

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) ***/

menupopup:not(.in-menulist) > menuitem, 
menupopup:not(.in-menulist) > menu {
  padding-block: 2px !important; /* reduce to 3px, 2px, 1px or 0px as needed */ 
  min-height: unset !important; /* v92.0 - for padding below 4px */
}
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;
}

/*** Proton Tabs Tweaks ***/

/* Adjust tab corner shape, optionally remove space below tabs */

#tabbrowser-tabs {
    --user-tab-rounding: 6px;
}

.tab-background {
    border-radius: var(--user-tab-rounding) var(--user-tab-rounding) 0px 0px !important;
    margin-block: 1px 0 !important;
}
#scrollbutton-up, #scrollbutton-down { /* 6/10/2021 */
    border-top-width: 1px !important;
    border-bottom-width: 0 !important;
}
/* Container color bar visibility */
.tabbrowser-tab[usercontextid] > .tab-stack > .tab-background > .tab-context-line {
    margin: 0px max(calc(var(--user-tab-rounding) - 3px), 0px) !important;
}

I do not use the majority of keyboard controls in Firefox-- only Ctrl+F. Lately, I've noticed that using Ctrl+I in editor windows also pops up the Page Info window, which I have never used on purpose and am perfectly comfortable accessing via Firefox's menubar.

I have been searching for over an hour, and every Firefox add-on that I can find to fix this problem has been removed.

Ideally, I would like to be able to configure all of my keyboard shortcuts, but practically I will settle for being able to disable Ctrl-B, Ctrl-I, and Ctrl-U.

Greetings... I would like to increase the font size in right click menu box in FF 89.0 (64-bit) (see attached png)

I found a similar 2018 query here at: https://support.mozilla.org/en-US/questions/1241117#answer-1174375

and based on that exchange I added the following to userChrome.css file

/* FONT SIZE IN RIGHT CLICK MENU BOXES 5/1/22 */

1. mainPopupSet menuitem,
2. mainPopupSet menu { font-size: 16pt !important; }

/* */

I closed and reopened FF. This change has no effect on the menu font no matter what font-size value I enter. Have I done something wrong?

I want to change background color in Firefox from white to gray (because my eyes get tired of white)

I try to change it this way: Preferences -> Language and appearance -> Font -> Colors

But it does not work as expected on some complex web sites. All I want to do is to darken the background, but not to change color of other elenments (links, text, scrollbars).

Can I do it in Firefox ? How [Preferences -> Language and appearance -> Font -> Colors] works in Firefox? Perhaps, there is some "override css" for the entire browser?

I keep accidentally muting my tabs when all I want is to click on them to switch to them.

I don't want the option to mute the tabs at all. I just simply want to switch to the tab when I click on it.

How do I do that?

My version is 89.0

I've used Firefox since 2001. Twenty years I've been able to customize it like I want.

A few months ago I switched from ESR to Release channel because the release version could still be tweaked to the way I like it. Huge mistake!

Version 89 totally destroyed everything I like about Firefox! I use Firefox on a large monitor from my easy-chair. I NEED compact layout. Everything is zoomed anyway. I hate the new tabs! I ESPECIALLY hate the double-spaced bookmarks! I want to continue to use a custom CSS in "chrome" folder.

I switched back to the ESR channel (FF78) and had to re-tweak my about:config settings, reinstall and tweak add-ons and load hundreds of bookmarks to get the favicons back. Unique favicons make it much easier to differentiate between sites. Generic icons suck. Major hassle!

I will stick with Firefox ESR until it too becomes unusable for me. At that point, sadly, my decades long use of Firefox will come to an end.

I include two screen grabs that illustrate how I like my set-up. Note how easy it is to tell one tab from another.

Why "fix" what ain't broke?

A moderator named tiny has this to say about my theme:

"Hello,

Your add-on, Green 1.0, has been reviewed and did not meet the criteria for being hosted in our gallery.

Comments: Spam content" I made that with firefox color

For over a year (just over a year on this computer and a few more years on a different computer) I have had a custom theme at the top appearing from the file menu through the address bar. The computers have also always had the New Tab menu being a light colored screen. I turn on the computer today, to find I guess Firefox updated last night? and completely got rid of the lightness of that page to make it dark, leaving me on the verge of a migraine every time I have to look at that thing.

How do I get rid of that dark page, back to the lighter version WITHOUT getting rid of my custom banner at the top? (yes I tried to use the light extension in theme and that gets rid of the banner and leaves me with a horrible white at the top which is just as big of an issue for me as all the black. I really need that like muted Tan back.)

Could you add a option of closing tab with <kbd>Ctrl</kbd>+<kbd>w</kbd> to the advanced preference?

Also, I realized that:

```browser.tabs.warnOnClose False``` Does this option activates warn when closing the tab? If your answer is yes, it is not working at all.

I note that Amazon are included in your list of "suggested search engines". Amazon is mostly a shop, so why is it allowed an unfair trading opportunity? The solution to this must surely be to allow users to type in the website of their choice? e.g I might want to use the search primarily for books and prefer " https://blackwells.co.uk/bookshop/home"

I've already found the solution, but wanted to share that Version 90 created a problem with Print Preview and Shrink to Fit. Uninstalling Version 90 and re-installing Version 89 fixed the problem. With Version 90 the Print Preview function (which I love) didn't work properly. When I try to Shrink to Fit any page, the first page shrinks, but the second page isn't pulled into the first page. Also, there's missing information on both pages. If there's another solution so I can use Version 90, please tell me. If not, and Mozilla is doing away with Print Preview (and Shrink to Fit), I'll have to do away with Mozilla Firefox. Sorry, but that's the main reason I use Firefox over Chrome. Perhaps I can find another browser to do what I want. I hope not though.

When I click on some sites that have images from Instagram, I get a link where it says I need to go to Instagram to view it however, before that link loads, for a split second, there is an option that appears in the same space that has a toggle setting for "always show images from Instagram" or something like that. I click on it if I am fast enough but it doesn't save the setting and it will show when I click 'Next' to the next image.

I can't find anything in the settings to change this and I am not on Instagram, nor want to be, and I do not want to change browsers... Any ideas?
