Firefox Support Forum

I've been trying to get a video to play for over a day now, drm-controlled content is checked but firefox won't install the widevine plugin, it just keeps saying that it will install shortly. I even deleted the cache in hopes to fix the problem, but it did nothing. What can I do to fix this? Also, and I don't know if this is a related problem, some websites just don't show up. It will say they are loaded but all I get is a blank screen (dailymotion and instagram so far).

This question was already posted and badly answered in 2016. Now things have changed a lot and Firefox DO try to translate everything which is quite annoying to anyone knowing more than a single language. No extensions related. I need to completely disable that. My firefox is up to date: 118.0.1 (64-bit).

Thank you Arturo

I have bought a new pc with Windows 11 home pre-installed and set Mozilla Firefox latest version as default browser ...the issue i am having is placing add-on extension shortcut icons on toolbar. I installed Norton Safe Web and this installed ok and is listed in extension control panel and when i click puzzle icon Norton Safe Web is not shown under manage shortcuts nor can i see option to Pin to Toolbar. Have tried several attempts but still get nowhere.I uninstalled Mozilla Firefox...restarted pc ... did a fresh install of Mozilla Firefox without altering any settings..re-installed Norton Safe Web and still cannot see option to Pin to Toolbar.Clicking the gear icon does not help Have i missed a step somewhere ?

I turned off Firefox updates because I'm sick and tired of having to download a new version at least once a week. So now I face a different problem. Every time I turn on Firefox I'm greeted by this annoying, unwanted pop-up spam message:

I want to disable this. I do not want to update, and I do not want to be reminded to update. Please don't waste both your and my time by replying "but you have to update". No I don't. I have nothing sensitive on this PC so even if I got infected by a virus or whatever because it's not the newest version, nothing bad will happen to me. At least nothing I consider as bad as having to update every single week. If there is no solution possible, I will simply stop using Firefox and use a different web browser instead. Thanks.

Hi, I have been using an extension that helps with my school's website for years and now for some reason it has been taken off the firefox store. It's still up on chrome and edge and all of the Dev's other add-ons are still up, its only this one on firefox. I emailed the dev and he sent me the zip file and I've been having to install it as a temporary add-on with the .json file every time i open firefox and its getting really annoying after a year of doing this. How can I just install it permenantly?

Firefox 103 screws with website zooming if you use the "Make text bigger" accessibility setting in Windows. 150% for example now zooms in a lot more with the accessibility setting in Windows set to 120%.

How do I undo this change so that 150% is 150% and not bigger than 150%? I had all my frequented websites set up how I liked it and now this comes along and messes it all up >:V at the moment it seems like 120% Firefox + 120% Accessibility is similar to what 150% in Firefox was like but it's not exactly the same. I've now gotta go futz with zoom levels for each web page I frequent again to find what looks most comfortable for each one.

Also this change greatly modifies consistency when it comes to the granularity of zooming. For example, what is 100% zoom when Accessibility is set to 120% so that I can avoid filtered scaling being applied to pictures? Why is the in-browser percentage indication not accurate with the level of zooming actually being applied?

The zoom level I choose is no longer the zoom level applied, there is now a multiplier in effect. So 50% isn't 50% anymore, 60% isn't 60% anymore, 70% isn't 70% anymore, 80% isn't 80% anymore, 90% isn't 90% anymore, 100% isn't 100% anymore, 110% isn't 110% anymore, 120% isn't 120% anymore, 130% isn't 130% anymore, 140% isn't 140% anymore etc.

A website that looked good at 133% can no longer be viewed at 133% if the Accessibility setting isn't also 133%.

Not a fan of whoever decided to implement this seemingly without a way to turn it off.

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.

Many file types are no longer listed under Settings > Applications>Content Type at about:preferences#general. I used to be able to click on a file in an email like a Word or Excel document, and it would come up on my screen. Now Firefox asks me to Save them. I don't want to automatically save files without first looking at them. How can I get those file types in the Application list again?

I have attached a pic of the file types I have left to chose from. There used to be a lot more. How can I get back all the missing choices I have had there for years?

Hi,

Often the ctrl + m (mute tab) shortcut gets in my way while using the browser as i use this shortcut in something else. I would like to know if it is possible to disable that.

Thanks. (Message written using Google Translate)

Is there a way to remove recent bookmarks from the "hamburger menu" (says "Open Application Menu" on hovering)? The bookmarks there seem to only show the most recent bookmarks added and there's no way to organize those or delete them without also deleting the bookmarks from the main bookmarks menu, which can be organized. There should be a way to not show bookmarks that are private bookmarks just because they've recently been added. I couldn't find an answer to this anywhere in support -- though I might not have been searching the right terms. Any and all help would be much appreciated. (Also, apologies if I put this in the wrong category. Wasn't sure what to use.) Thanks!

Firefox does not print the right edge of web pages that are made in landscape mode.

I set FF to "Fit to page width" but it does not print the right edge. It's cut off.

And there is no Orientation option available. Not sure if that has any significance because it supposed to "Fit to page width" anyway.

What's the work around to fix this?

I use layout.frame_rate 1 to block animation, and to replace painful partial scrolling with clean jumps. I can't use an intermediate frame rate, such as 3-30 fps, due to the seizure risks, or a high frame rate, such as 60 fps, due to migraines when hit by "smooth" animation, "ease in-out" animation, zooming animation, parallax animation, partial scrolling with one part of the window sliding alongside another, etc.

about:config involves some other frame-rate and frame_rate settings;

gfx.display.frame-rate-divisor starts at 1

layers.offmainthreadcomposition.frame-rate starts at -1

layout.expose_high_rate_mode_from_refreshdriver starts at true

layout.frame_rate starts at 0, which defaults to monitor settings; I've reset it to 1 (1 frame per second).

layout.throttled_frame_rate starts at 1

What are these and what do they do? I've tried looking them up, and see a bunch of posts about browser diagnostics, or *increasing* frame rates, or the like.

Dear Sir or Madam,

I'm running 101.0.1 and spell check no longer works on any mail app like Gmail, Outlook, Yahoo, BT Mail. If I use Chrome or Edge then spell check works correctly. This is despite my Firefox Settings being as below.....

Language Choose the languages used to display menus, messages, and notifications from Firefox. ENGLISH GB Set Alternatives… ENGLISH GB Choose your preferred language for displaying pages. Choose… ENGLISH (United Kingdom) (en-gb) Check your spelling as you type = Tick (Yes)

Could you please advise a fix?

Kind regards,

Neil.

P.S. If I use Chrome or Edge then spell check works correctly.

In my Firefox settings, I have PDF files set to "Open in Firefox".

When I click on a PDF file, Firefox DOES open the PDF in a new browser tab, but the PDF ALSO downloads to my desktop (both!). How can I stop it from downloading?

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).

The mute icon only shows on hover and takes up 50% of the tab size so I'm constantly accidentally muting tabs without realizing it and silencing video calls and the like. The top Google result for this issue -- rightfully yelled in all caps because this is an absolutely horrid UX -- says to set browser.tabs.showAudioPlayingIcon to false, but that does absolutely nothing in FF 100.0

The Firefox desktop browser default font is replacing all fonts on some websites, only title fonts on some others, and then leaving others unchanged. It seems random, and I can't stop the default font from taking over randomly on most websites no matter what I do. This was not happening until today, and no browsers or general MacBook Air preferences were changed between today and yesterday when I last used the browser on desktop.

Under Firefox Preferences » Fonts » Advanced, I've made sure to check the box to "Allow pages to choose their own fonts instead of your selections above", and I've unchecked it, and I've re-checked it, and the default is still overriding fonts on most websites.

I've quit and restarted Firefox 3 times.

Help!
