Firefox Community Forum

The Alt-<number> keyboard shortcut is used to switch between tabs. However, the key event used to switch a tab seems to also propagate down to the content itself. This creates weird interactions:

- I switch to third tab - The web page running in the third tab actually uses Alt-3 to do something - After switching tabs the web page does something unexpected because the browser chrome didn't swallow the event during its tab-switching procedure.

The most irritating candidate seems to be XenForo forum software that uses Alt-<number> to go to different sections in its menubar. For example, alt-4 seems to open a search page and going there provides no new entry in the browser history. So, if I've tab-opened the forum to display new posts and then later I switch to it using Alt-4, it makes the content go to its search panel with no way to go back to new posts. Ironically, switching _away_ from the tab 4 does not register to the content so I can't even use the forum's own keyboard shortcuts to navigate back to new posts section or any other section. Having the forum in tab X will only ever let the forum see Alt-X and nothing else.

This all stems from the fact that Firefox lets the initial tab-switching key event through whereas I think it shouldn't. It maybe should if the corresponding tab is already active but it certainly shouldn't when a tab-switch actually occurs.

I've obviously disabled the content's capability to override keyboard shortcuts but it doesn't help in this because the content is not overriding anything: it seems to be just listening to a keyboard event that it shouldn't see.

Did I miss some option in about:config or do others see this as well?

There are certain websites that, on firefox only, display apostrophes and quotations as Russian letters. For example, on google docs, if I type "He's such a great friend" it will display уHeТs such a great friendФ. When I open the document on the app, it is normal, but I haven't been able to figure out why it does this on my computer. I use Mozilla Firefox for Fedora 149.0.2 for reference.

I used to paste a text selection (temporary clipboard) into the URL bar and it would replace the loaded text/url. Now, it inserts it to the existing content at the point of the cursor. Why does it do it now? Is this an option i have to disable or is it a bug?

This is on v151 now

A while ago I made some changes in about:config and also in my ~/.config/gtk-3.0/gtk,css file so as to control my scrollbar and slider -- making them more visible:

/* Log out, and back in for these changed to take effect: */

scrollbar { background-color: #cccccc; } scrollbar slider { min-width: 20px; }

/* dark green: pointer is not in the active window */ scrollbar slider:backdrop { background-color: #00aa00; }

/* green: pointer is in the active window but not on a slider */ scrollbar slider { background-color: #00ff00; }

/* dark red: pointer is hovering over slider but mouse button not pressed */ scrollbar slider:hover { background-color: #aa0000; }

/* red: slider is active */ scrollbar slider:hover:active { background-color: #ff0000; }

/* No effect: */ /* scrollbar-color: blue white; */

... it works half the time. Some pages obey the above settings but other pages continued to show a scrollbar about a mm wide with the slider so faint as to barely be visible. So, in 'about:config' :

widget.non-native-theme.scrollbar.size.override 30

... at least made the narrow scrollbar a bit wider. But how to change it's color? Doing this in a file:

~/.mozilla/firefox/5dqk4533.default/chrome/userContent.css:

html,body{

   scrollbar-color: yellow blue !important;
  }
.... doesn't change anything.  Is there some complete guide to controlling the srollbars?  Nice if it could all be handled in one place of course.

Hello! I really liked the vertical tab panel management before, if I wanted it to disappear I've pressed ctrl + alt + z and if I wanted it to show only icons of the websites - I could press ctrl + alt + x twice and had the mini version of it. For some reason, now it's gone, when I press ctrl + alt + x twice the panel is gone completely. Could you help out here? Essentially, I want to be able to make it look like that (screenshot attached), only without the AI Assistant.

I have used the new and old profile system, and I use Firefox Nightly. On one of my profiles I am unable to delete profiles created with the new profile system.

When I use Manage profiles and click the delete icon I get about:deleteprofile but clicking the Delete button nothing happens. The display doesn't change, no message appears in the browser console, and the profile doesn't get deleted.

This is running Firefox Nightly 153.0a1. When I use Firefox 151 on the same system (different profile) the delete works fine. When I use the same version of Firefox Nightly on a different system about:deleteprofile works fine.

Both computers are running Ubuntu 24.04.4 LTS. The new profiles don't show up in about:profiles. I now have several profiles I can't delete following the instructions from https://support.mozilla.org/en-US/kb/profile-management#w_delete-a-profile . Most of them I created, closed the window, and immediately tried to delete.

Following the instructions from https://support.mozilla.org/en-US/questions/1572980 and https://bugzilla.mozilla.org/show_bug.cgi?id=2000125#c4 I looked at the toolkit.profiles.storeID preference. The preference is the same in the child profiles as in the original profile.

I tried starting the original profile in Troubleshoot Mode. That had no effect on the behavior.

past firefox 150 Drag-and-drop for graphics is no longer working; instead of the graphic itself, the graphic's link appears at the destination.

I Admin from Community marvin-und-lisa.de Several users have complained that they can no longer play certain games in my community, because the images can no longer be loaded; instead of the image itself, the HTTPS address of the image appears.

Lastpass for Ubuntu will not install Successfully executing the "keyrings" CLI sequence did nothing to solve the issue. Lastpass works fine on another browser. What is wrong with Firefox?

I have Firefox set to "ask me every time" what to do with doc and docx files. When I click on one, I get the popup shown in the image. As it shows, for some reason, okular (a pdf viewer) is shown as the pre-selected "open with" option. The dropdown menu also includes LibreOffice Writer, and says (correctly) that this is the default program.

I cannot find any setting on my system where Okular has been associated with doc files. So I think this is a Firefox problem.

How do I remove Okular from this dropdown, or at least make LibreOffice Writer the default pre-selected option?

Description of the issue: I am experiencing an issue where I cannot paste images from my system clipboard into the chat box of Doubao (a web-based AI chatbot: doubao.com).

Steps to reproduce:

   Copy an image to the clipboard.
   Open doubao.com in Firefox.
   Click on the chat input box and press Ctrl + V (or right-click and Paste).

Expected result: The image should be pasted into the chat box and ready to be sent.

Actual result: Nothing happens. The image is not pasted.

I have MozillaFirefox-140.4.0-150200.152.207.1 on OpenSuse Leap 15.6. In my "Settings" under General and Startup I have always had the option "Open previous windows and tabs" checked.

This just started happening recently. After the first time it happened, I restored everything by searching through "History" and recreating the tabs and windows. Everything seemed OK for a few days then it happened again.
