Firefox Support Forum

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

Why why why why is FF forcing download of pdf files? It is a horrible problem for me.

Especially because I am a university prof and, in the classroom, constantly display (my own!) files from the course management system on the classroom devices. I DO NOT WANT MY FILES SAVED ONTO THE (PUBLIC) CLASSROOM DEVICE. Never mind multiple copies as it will download EACH AND EVERY TIME I open it.

I have been looking everywhere for a solution or a way to disable this feature, there seems to be no such option but I am seeing a lot of posts from people who object to this as much as I do.

After many many years of loyally using FF and a paid subscriber to some Mozilla services, I am afraid I am going to have to give up using FF is this isn't fixed NOW.

Hello Support:

My MacBookPRO OS was updated to Monterey 12.3.1 I lost my favored settings in Firefox. The Firefox settings loaded to default settings

. I would like to recover my Firefox settings. Is this possible? Is there a step by step "punch card" list to get the set back for the former state?

--Regards, Richard

I just installed firefox on a linux machine, and spontaniously, I keep getting a message pop up toward the top of the screen saying: "To play videos, you may need to install the video codecs".

This occurs when I am not even trying to play videos. I can play youtube videos fine. I don't need to install anything. It normally occurs when I am checking my outlook email, but can happen at any time.

So my question is, how do I stop this message from coming up? Prefereably WITHOUT installing some codec that I do not currently need.

Another message that comes up is an offer to install an outlook extension to my browser, but this is triggered by opening outlook email. I have no need for this either, so it would be nice to get rid if this message popping up as well.

Thanks

Hi guys:

I use Firefox on a Mac (Big Sur OS), and all of a sudden when I updated to the latest Firefox version -- each time I click on Firefox it opens in a new window other than the one I'm working on which is **really** annoying! What can I do to prevent this? Is there some adjustment in preferences I'm not aware of? Please help!!

Thanks much,

Kelli

Hello. With version 100.0 came multi-language spellchecking. I would like to know how exactly does it work, please.

For instance, if I enable both English and French, will it simply virtually add the two dictionaries and use the resulting combined list of words? Or will it try to understand if a paragraph or sentence is English and mark non-English words in that paragraph/sentence as incorrect even if they are French?

I am obviously asking this because there is no detailed information at https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker.
