Firefox Support Forum

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?

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 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.

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...

Alex

P.S. Attached screenshot...

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?

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

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.

The new selection "Copy without site tracking" may eliminate certain codes, but does not remove all invasive data (my term). Consider this common URL occurrence:

link text

The new filter does absolutely nothing to this and when I pass this kind of URL on to others, I do not want to include all that crapola. Currently I have to manually edit the link, which can really get tiresome when passing on a lot of links.

Is there a way to modify anything in Firefox to accommodate this?

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,

I'm trying to use the, "*", "%", "^", in my browser bar. What exactly do these do? After entering the shortcut I get a "Tab" or "History" button that shows up in the search bar and then after hitting enter nothing happens. Isn't this feature suppose to search inside all my open tabs and my History? Nothing happens after I hit enter.

Thank you.

I have many addons and some add a context menu with specific options. One that I often use is "Copy Plain text". Can it be moved upwards, can the order of the context menu list of options for addons be customized?

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.
