Firefox Support Forum

Good morning. My Firefox version is 117.0 and I am running Windows 11 Home. Currently except for Ublock all my other addon icons are grayed out on my toolbar. My webadvisor, Capital One, just gray. This is a new behavior and I'm not sure what happened. I am also curious why just Ublock is colored in. Thanks in advance for any help you can give.

I used to be able to send tabs between my devices, say when I go from my home computer to my laptop. This option seems to have gone missing, like I don't even see the option when I right click on a tab. What happened to this option? Did I somehow disable it? Can it be restored?

I installed Firefox-ESR on my Raspberry PI and noticed that I cannot play Udemy videos. After some research I found that the Widevine plugin is missing and the OpenH264 Video Codec is also not installed. Following the instructions from similar issues didn't solve the problem. I ticked off and on the "Play DRM-controlled content" button but this only brings the widevine plugin for a moment and after that it disappears. In the network tab I see no activity when click on this button, i.e. Firefox does not send requests.

Additionally the OpenH264 Video Codec is not installed and never installs.

Any ideas how to solve this?

I went into setting and made sure spellcheck is enabled and it is, but there are no other options there. I did exactly what it said on your help article and right clicked in the text box on multiple different web pages and there is NO OPTION. It should not be this complicated.

I can't figure out how to delete this extension: Adobe Acrobat. It's disabled, but I want to delete it.

When I open Firefox settings I can set; Firefox Home (Default), Custom URLs..., or Blank Page. I altered the Firefox Home to show a custom image per [[How to add image to my firefox home page / newtab page|https://support.mozilla.org/en-US/questions/1288490]] . Now I'd like to show the Firefox Home page every time I open Firefox or open a new blank tab.

When I read the article [[How do I set a different Home page and Home button|https://support.mozilla.org/en-US/questions/1341696]] the options in "about:config > browser.startup.page" are limited to "0-blank; 1-home page; 2-last visited page; 3-restore previous session", but there is no Firefox Home page in this option.

So, it seems I cannot have Firefox open to my custom Firefox Home page (and NewTab) image and have the home button open to my corporate web site. Is there another option that I can accomplish this?

Hello Mozilla Support Team,

Since one of the last updates firefox Download Setting seems not work properly...

Into Settings > Files and Applications > Downlods > Save files to option is ALWAYS on, even when "Aways ask you where to save files" option box is checked. When I open a PDF in view mode with Firefox, it automatically download it to the location described into "Save Files to"..in my case Desktop. It seems that the "Save Files to" option doesn't gray out when "Always ask..." option box is checked.

Do you have any idea why I can't chose just one of the two options?

Thanks for you help...

Hello!

I have the problem that every of my most visited sites are loading normal fast except for YouTube.

YouTube needs about 2 to 3 seconds to load the site itself and the thumbnails like "lagging" pictures which are rendering real slow while my other most visited sites like Twitch, Reddit or Twitter are loading in about 1 second or less. (i have installed the "Page Load Time" addon to check that).

I have only installed uBlock and nothing else.

When I click a mailto link it brings up the GMail app. Instead I want the Yahoo Compose window. Several posts suggest various arcane methods. Either they do not apply or they require hacking. Has the situation improved?

How can I make mailto links go to the Compose window on mail.yahoo.com?

Hello all. I'd like to restore the backspace button function but the previously workable solution — resetting browser. backspace_action to 0 — is not working for me. Any hints as to why that might be the case?

Firefox's behavior changed, after v116.0.1 (64-bit) was installed. My "Setting" selection is (and always has been) is the default (display Home Page)

My OS is Win 10 Pro v22H2 (OS Build 19045.3208)

See reddit post— no way I'm typing all that again! Reddit Post It's not that long, trust me— it's just that the code is long... I've attached a slightly different screenshot to the one I posted on the reddit post, but it makes no difference if you see one or the other, or both!

In summary, I've added a css code to my userChrome.css thingy to move the tabs below the search bar. I was also wondering what the best way to transfer my userChrome.css file + about:config settings over to a new version of Firefox. Due to not being admin of my laptop (I'm running it out of the .dmg file— besides, I always like to keep an older version of Firefox as a fallback), I have to install a whole new version of Firefox onto my laptop to update.

Thanks!

Hello folks,

I am writing to you because I am having a problem with the microphone in Firefox on Windows 11. The microphone works on all other apps on my computer, but it does not work in Firefox.

I have tried the following troubleshooting steps:

I checked if Firefox has permission to use my microphone. I restarted Firefox. I updated Firefox to the latest version. I disabled any extensions that I have installed in Firefox. I tried using a different microphone. I checked my computer's sound settings and volume mixer. I ran a virus scan on my computer. I reset Firefox to its default settings. I reinstalled Firefox. Tried downloading Firefox from Microsoft Store. Went through every article on the internet but none of the solutions worked in my case. After trying all of these steps, the microphone still does not work in Firefox.

I would appreciate it if you could help me troubleshoot this issue. My audio driver version is the latest that the manufacturer(Lenovo) could offer for my machine which is ideapad Creator 5-15IMH05 Laptop - Type 82D4, Windows update also does not offer any newer version than the one i am currently using.

Thank you for your time.

I use userChrome.css and userContent.css to (1) turn unvisited links bright red, and (2) turn visited links bright purple, and (3) add underlines to all links.

This works well on light backgrounds, makes links easy to see and easy to distinguish from other text, but makes them harder to see on pages with dark backgrounds.

Is there a way to vary the link color to improve contrast? I can't use the default colors because most sites use blue links which are hard to distinguish from black text.

We are distributor of Firefox extension for dragon professional. ( We are self distrubutor of the extension.)

It’s ID is dgnria_pro.firefox@nuance.com

Now we have done some modification to the same extension, while publishing it shows error as “Duplicate add-on ID found.”

Earlier we have used same ID for the Firefox extension in the year 2018.

Currently we have opened new account with same ID “dgnria_pro.firefox@nuance.com” and faced the mentioned issue.

We are expected to publish our extension with the same extension id as we don’t want our existing customers get affected.

Is there any way with which extension id “dgnria_pro.firefox@nuance.com” can be deleted from backend , so that we can reuse it.

The settings page just shows a number, but no units as on my laptop's default font settings page. I think that they are pixels, but I'm not sure. I want to set my font sizes in points, so that the text will appear the same size on my laptop's screen as on my much larger external monitor.

The following HTML feature is the subject of this question.

<input type="time"> https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/time

Firefox is supposed to use a 12- or 24-hour format for input depending on region settings or locale.

I think I should see a 24-hour input format. Firefox only ever presents me with 12-hour input format -- with AM/PM selectors. Chrome, by comparison, presents 24-hour input format, out of the box, as expected. Is this a localisation bug in Firefox, or am I holding it wrong?

I shall try to upload some screenshots, but in case that does not work, here is a text representation of my state.

I am on a Mac. The Mac is configured for en_AU. (I believe 24-hour clocks are used in the en_AU locale.) Just to be sure, the "Time format: 24-Hour Time" checkbox has been enabled in the Mac's Language & Region system preferences. The following command, entered at a shell, produces the desired output format.

% date +%c Sat 26 Aug 22:48:14 2023

All other applications on my computer honour this preference to the best of my knowledge.

I have the en-GB release of Firefox Nightly. Build ID is 20230825041349. Here are the relevant sections from about:support...

Application Settings Requested Locales ["en-GB"] Available Locales ["en-GB","en-US"] App Locales ["en-GB","en-US"] Regional Preferences ["en-AU"] Default Locale "en-GB" Operating System System Locales ["en-AU"] Regional Preferences ["en-AU"]

intl.regional_prefs.use_os_locales has been set to true in about:config.

Why do I still see 12-hour input formats in Firefox?

Thank you.
