Firefox is having issues opening files in my tempdir directory. Opening a file directly, via File -> Open, there are no problems. But, when using either drag-and-drop or when trying to open an attached file from Thunderbird I will get something like the following:

File not found

Firefox can’t find the file at /tmp/pid-15374/etfExpectations_2022-04-22.pdf.

   Check the file name for capitalization or other typing errors.
   Check to see if the file was moved, renamed or deleted.

Ever since the last update, every time I download something on Firefox this download tab pops up every time when the new download is complete. Ive tried disabling every extension, Ive tried the about:config solution I found on this page, setting it to "false" and I havent been able to find anything in tools or settings.. but nothing disables it and its getting annoying. Ive had Firefox for years and this has never happened before.

Hello, so I am not very experienced and recently discovered how to customize Fire Fox using the userChrome.css file. I went through all of the steps that are required in order to do this. I set up a folder called chrome in the directory /Users/my name/Library/Application Support/Firefox/Profiles/x1oheo82.default-release To test if it works I wrote this into the userChrome.css file: @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */

1. TabsToolbar{ background-color: #FF0000 !important }

and set toolkit.legacyUserProfileCustomizations.stylesheets to true After restarting Fire Fox I saw that nothing changed. I double checked if there was a hidden file extension or if I might be in the wrong directory. I tried different code to see if there was some error in the code but nothing changed. I watched countless tutorials on You Tube and tried to find answers on google but nothing that I did seemed to help. I don't know if it has something to do with the operating system I am running or if it is a limitation of my computer hardware (I am running Fire Fox on an m1 mac).

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 got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.

I am developing an extension. I am running the extension locally and I have noticed that it doesn't load on this page (https://support.mozilla.org). Is there some limitation to running extensions here? The same extension works fine in google chrome for this page. It is very important for me that the extension runs everywhere since it's an accessibility extension.

Firefox is still automatically downloading files to a default directory, even though I have selected "Always ask you where to save files". This is a security risk. I want to be asked BEFORE the file is downloaded so I can choose the location or choose not to download. Thanks...Jim.

The instructions for the Window Titler icon suggest to turn on the Title Bar (with the Firefox icon, usually shows title of active tab, but would presumably show the Window Title if one was assigned). I can't find how to turn it on in version 99.0.1. It's not where the instructions for Window Titler said to look (managing the Menu bar or the Bookmarks bar). Any suggestions?

Would love for this feature (named windows) to become a normal part of Firefox. I wouldn't mind having the Title Bar anyway; at the cost of a few pixels, I would have something to grab onto when moving windows around that wouldn't accidentally do something to a tab.

please take off the red add, the pop up total add sign that keeps popping up asking to paid for the add block I am 82 and on a fixed budget. I do not want this service. How do I get it off my computer. When I want to print an article from an e mail.I always have to remove it to save an e mail, or when I want to print an article, I read it later, and I see the total ad block on my printed article stuck on the printed page blocking out what I printed. Its very annoying to have to take it off the screen before I print anything. Please help me. George at [removed email from public]

In the location bar (aka url bar aka address bar), the base domain name ("example.com") is displayed as normal text, whereas everything else in the url is displayed in gray. For example, if the displayed url is https://foo.example.com/bar, the "https://foo." and "/bar" are in gray.

Is it possible to get the whole url displayed as normal text, i.e., black, and avoid this "graying out" of some of it?

In my searches so far, I've found various other customizations for the location bar via userChrome.css, but not this one. Any help appreciated.

I'm using firefox 91.8.0esr (64-bit) as currently packaged for centos7 (x86_64), though presumably this is not system-dependent.

Hi,

I was very disappointed earlier on today when I saw the many add-ons you can choose from, for the 1st time, and tried to install one I really liked on my desktop (which runs on XP PRO).

The add-on is called "I Don't Mind Cookies". It wouldn't install as I needed to update the version of Firefox I currently used and provided me with a link to facilitate this.

I followed all instructions throughout and surprisingly quickly I found it completed, and had message confirming the successful update of OS to ver.59 2.

Returned to add-on above and tried to install it again. I must say I felt even more disappointed when the same error message appeared. Clearly, the add-on was not so sure I'd done as directed; either that or it perhaps it got confused and then passed it on to me...

Can anyone help me, please, as I've had an awful outing this week trying to get our Sky Account sorted - my repeated attempts to get 2 things sorted culminated with my last call taking well over 2hrs, involving 5 different departments and a total of 7 agents - thankfully, I only had to tell 4 of them the whole sorry tale in full and although this sad episode was finally resolved (well, sort of), I'm not confident I'll ever be quite the same again.

I just had a Firefox update today and now when I save a pic or save a video it does a new really annoying drop-down notification at the top from the download icon area which stays there until I manually remove it. In the past I only saw an activity up there when I downloaded programs to my downloads folder, but not when I simply saved an image or video to my other locations. I do not want this stupid dropdown notification appearing, and it's getting bigger and bigger the more pics I save, how do I turn it off? It's ridiculous. I save videos from twitter and images like memes all the time and never have this happen, it just saves it and there is nothing more going on to worry about (which is what I want), it's only started today after the update so it's a new feature. I looked in about:config but I could not work out which setting it is so didn't touch anything. Thanks for your help.

I work on kubuntu 20.04 with plasma 5.18.8 desktop environment. I have a QtCurve-based custom application style, which I almost match with css for GTK apps. Firefox has to be an exception by itself! Not only that, but it changes my ability to customize its interface, from time to time and even changes access to such ability, on some updates.

My scrollbar customizations in userChrome.css and userContent.css do not work any more (other CSS changes still work, for menu/addressbar/tabbar/bookmarksbar orderint and tab styling). I had to resort to settings in user.js file, to get a 20px width scrollbar, suitable for my big screen, but... it gets very wide when I increase the focus, on some webpages and becomes very ugly! Furthermore, I cannot make sense of the proper use of "ui.themedScrollbar*" settings and the scrollbar and its slider result in the same color. These are my settings in user.js:

user_pref("widget.content.gtk-theme-override", "backwater"); user_pref("widget.non-native-theme.enabled", false); // Use GTK-3.0 gtk.css: set to false user_pref("toolkit.legacyUserProfileCustomizations.stylesheets", true); // Use userChrome.css & userContent.css: set to true user_pref("widget.gtk.alt-theme.scrollbar_active", true); user_pref("widget.non-native-theme.scrollbar.size.override", 20); // If nothing else works, fix scrollbar width to 20px user_pref("widget.non-native-theme.gtk.scrollbar.round-thumb", false); user_pref("widget.non-native-theme.gtk.scrollbar.thumb-size", 1.0); // originally 0.75 user_pref("widget.non-native-theme.gtk.scrollbar.allow-buttons", true); // it was true, anyway... user_pref("layout.css.cached-scrollbar-styles.enabled", false); user_pref("layout.css.color-mix.enabled", true); user_pref("widget.non-native-theme.scrollbar.style", 4); // wide scrollbar theme: set to 4 user_pref("ui.themedScrollbar", "#bad1f5"); user_pref("ui.themedScrollbarInactive", "#668cc4"); user_pref("ui.themedScrollbarThumb", "#e4e4e4"); user_pref("ui.themedScrollbarThumbHover", "#e4e4e4"); user_pref("ui.themedScrollbarThumbActive", "#668cc4"); user_pref("ui.themedScrollbarThumbInactive", "#bad1f5"); user_pref("browser.dom.window.dump.enabled", false); user_pref("extensions.ui.sitepermission.hidden", false); user_pref("fission.experiment.max-origins.qualified", true);

Either with the "ui.themedScrollbar*" settings or without them (and cleared from the prefs.js file), the scrollbar and its slider result in the same color, unless I (tryingly) click on some place on the scrollbar outside its slider; then I can see the slider, _only_ for the duration of the mouse-down event (which causes up or down page-hight scrolling).

The default, very thin scrollbar, as well as my modified wide scrollbar with invisible slider are both useless to me! I have even tried fx-autoconfig (https://github.com/MrOtherGuy/fx-autoconfig) to make the scrollbar CSS work, but no result. At this point, I am considering switching to another browser, despite the trust I have to mozilla, for my data and privacy.

I cannot removed total adblock and especially the ad for total adblock. I tried to follow the instructions, but they do not bring up the menu that they are supposed to bring up. HELP

As from v100.0, Firefox allows users to "set their preferred color schemes for websites".

Ironically, this does not addresses complaints from users, including me, who wish for a consistent Light theme all across Firefox.

Even if "Web site appearance" is set as Light, the following still remain dark:

• Background of main drop-down menu (Containing "Sync and save data", "New tab", "Print", "Settings", etc)
• Background of right-click menu (Containing the refresh icon, "Save page as", "View page source", etc)
• Background of "Please enter primary password" menu
• Background of auto-filled user name and password menus
• Background of elements in a bookmark folder
• Background of Downloads menu
• Background of Print menu
• Background of "Clear all history" menu
• Background of "Find on this page" menu
• Background of "You are about to close X tabs" warning menu
• Colour of title bar for "About Mozilla Firefox" window, when the window is not currently active

Being able to set "browser.theme.toolbar-theme" permanently as 2 would fix all of the above, but users are still (Note: Since v96.0, when this complaint was raised) prevented from doing so. Why?

Each time Firefox updates, the email client changes to the outlook default. The last 2-3 updates, mailto does not appear on the file,settings,applications menu. Nor will it populate if I type it in. I have tried every instruction to no avail. I am a long-time firefox user, non-techie and it is discouraging when things disappear with each update lately. Would appreciate any suggestions. Thanks
