So I wanted to read PDFs trough firefox with a dark theme, looked up how to do so online, and people say to change the "about:config" option "pdfjs.viewerCssTheme" to "2" instead of "0", I did that, tried opening a PDF, nothing happend, it was still black text on white backgrounds. Tried closing firefox, reopened the pdf, nothing happened, still white backgrounds. Tried to check if it might have to do with that specific pdf file's config, created my own PDF file from a word document, tried to open it, still white backgrounds. Tried disabling extensions, (which I use four of, UBlock Origin, SponsporBlock, Return Youtube Dislike and Translate this page), didn't work. Tried enabling the option on my laptop, didn't work. Tried a bunch of other stuff and it still won't work. My Firefox version is 109 and I'm using Windows 10 I also don't want to use the console/file edit thing with grayscale(1) invertcolor(1) or whatever it was since it also reverses the colors of images instead of just the backgrounda nd text color.

As you can see in the attached image of my old Overflow Menu, I had it customized with many buttons/extensions I often accessed throughout each day.

With the advent of FF ver 109, this functional flexibility has been completely lost. Now, there's no way to choose what buttons and to sort them in the Overflow Menu. In my view, an egregious loss of convenience and efficiency.

Please, bring back the full functionality of the previous Overflow Menu!!!

I am trying to have Firefox show an "X" on every tab as soon as I hover above it. I followed a certain article and implemented this code:

/* Show Tab Close buttons only when hovered */

  1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]) > .tab-stack > .tab-content > .tab-close-button {
 visibility: collapse !important;
 opacity: 0 !important;
 transition: all 250ms ease-in-out !important;

}

  1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]):hover > .tab-stack > .tab-content > .tab-close-button {
 visibility: visible !important;
 opacity: 1 !important;
 transition: all 250ms ease-in-out !important;;

}

  1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]) > .tab-stack > .tab-content > .tab-close-button {
 display: -moz-box !important;

}


This code is however not being implemented no matter how many times I restart Firefox. 'toolkit.legacyUserProfileCustomizations.stylesheets' is set to True The location is userChrome.css is '/home/user1/.mozilla/firefox/yqomjsh9.default-release-1672744596809/chrome/userChrome.css'

What could be the issue? I tried adding executable permissions using "chmod" but that did not change anything.

So this crazy new update has broken my Firefox in these ways:

1. All my bookmarks on my bookmarks bar have been deleted. 2. I can't drag any new links to the bookmarks bar 3. Overflow menu for apps is empty and will only let me drag Firefox defaults to it such as settings. Dragging apps to it is impossible. It "is" possible to pin items by using the Chrome puzzle piece..

Firefox: 109.0 OS: Windows 10 Pro

Using troubleshooting mode has no effect.

When i set shortcuts for them they work, but all the new ones end up in that manu and are unavailable.

Any ideas? Thank you in advance,

The latest update added persistent "More Tools" and "Extensions" icons on the top right of Firefox. Usually, by clicking "Customize Toolbar" I could remove any annoying icon that I don't want to persistently see, but it would seem that Firefox DISABLED the ability to remove these annoying icons. Please let us continue to customize our own toolbars and allow us to remove unwanted icons.

I reset the Windows OS on my PC. When I reinstalled Firefox and synced it, the extensions automatically returned but their icons were missing from the address bar.

Worse they only work if I click the extension drop-down and specifically the extension. They used to be aware of the website and automatically do their thing. E.g. the NordPass symbol previously appeared next to passwords and I could click to have the password automatically filled in. Now I have to select the NordPass extension and copy the items one by one into the form. Ditto for Grammerly

And still worse the setting was synced to my laptop.

All of a sudden when I press F6, it starts a Google search (see image) instead of just focusing the address bar. This is rather annoying because I use F6 all the time to go to a different page (e.g. type "mail" and then follow the autocomplete to mail.google.com) and that doesn't work if it wants search google for mail instead.

How do I revert this to its normal behaviour?

Without my doing anything, firefox has decided to download pdf files in its own html. I have changed the default to adobe rather than ask. When I open the downloaded file in adobe it comes down as an adobe file, I tell it to save as an adobe pdf, but it appears in file manager and then opens in firefox html. Worse, it, whatever it is, has gone into file manager and changed adobe pdf files, some of which have been sitting on my hard drive for some years, into firefox html files. How do I rectify this please?

Issues with extension when "Always use private browsing mode" is activated

This is what my environment looks like: I am using Firefox (version 109.0) on Ubuntu (version 22.04.1). I installed the 1password extension for Firefox (version 2.5.1). I have allowed the 1Password extension to "Run in Private Windows" (from the Firefox Add-ons Manager).

Description of my issue: In Firefox, there is a Privacy&Security setting that allows you to "Always use private browsing mode". When this setting is enabled, the 1Password extension does not work at all (even if I allowed it to run in private windows). That is, every time I click on the 1Password icon in my browser, an empty browser tab shows up, and nothing more. Instead, if I disable that setting, the extension works correctly.

Hi All,

I'm trying to modify various userChrome.css attributes of Tabs in Firefox 109.

However, code that worked in FF 88 is seemingly no longer working.

Is the below code outdated?

I would also like to change the appearance of #TabsToolbar from translucent to either a solid color or a background image. Is that possible? Right now, you can see icons from the desktop through the Tab bar, and there appears to be a strange curved, black overlay colorizing it. See attached screenshot.

Thanks for any input!

/* MISCELLANEOUS TAB ATTRIBUTES */

  1. TabsToolbar { /* tab bar */
 -moz-box-ordinal-group: 3 !important;
 padding-top: 0 !important;
 padding-bottom: 0 !important;
 height: 25px !important;
 background-image: url("bkmr_back.gif");
 border-top: 1px solid #afc0d2 !important;
 border-bottom: 1px solid #8698aa !important;

}

/* Change the color of selected tab */

   .tab-background[selected="true"] {
       background-attachment: none!important;
       background-image: none!important;

background-color: #eef5fc !important; /* background color only, not border */ }

/* Change text attributes of selected tab #8698aa to match bottom tabstoolbar line color */

  1. TabsToolbar .tabbrowser-tab[selected] {

font-weight: 800 !important; color: #000 !important;

       border-top: 1px solid #8698aa !important;
       border-left: 1px solid #8698aa !important;
       border-right: 1px solid #8698aa !important;

}

  1. TabsToolbar .tabbrowser-tab:not([selected]) {

font-weight: 600 !important; color: #000 !important; /* non-selected tab text color */

       border-top: 1px solid #afc0d2 !important;
       border-left: 1px solid #afc0d2 !important;
       border-right: 1px solid #afc0d2 !important;

Hi there. I use Firefox in macOS, and I always have multiple windows in different Desktops.

As you know, Desktops in mac are numbered, and each App in the Dock has the option "Assign to" a particular Desktop number or Desktops in Display X. But that is too limiting, because all windows appear in the same Desktop. I'd like an option or Extension in Firefox that allows me to set each Firefox window to a particular Desktop number, so that I don't have to re-organize all my windows every time I restart Firefox.

Does anyone know if there is anything like that?

I have been fighting with Xfinity.com for too long now over a "rendering error occurred: invalid time value" message when I log in to their billing function for my account. I am using a Windows 7 PC with whatever Firefox version is the most current.

Among the responses from their "experts," I see something that has to do with "browser add-ons may be causing your problem."

I have looked at my Firefox settings > manage your extensions as well as settings > manage your plug-ins. Under Extensions enabled I have 2: Norton Safe Search and Norton Safe Web. Under Plug-Ins enabled I have OpenH264 Video Codec and Widevine Content Decryption Module. That's all. Could any of these be causing the problem?

Does this "rendering" error have anything to do with Javascript? (I thought Firefox did not support Java so never paid any attention). If it does relate to Javascript, how do I fix my Firefox browser settings to enable it for the Xfinity.com website to see if that fixes anything?

This is so incredibly discouraging.
