Firefox 커뮤니티 포럼

This started happening a few days ago.

I tried to drag a tab out of the main window to put it in its own window on my other monitor, but the tab just became unselectable, and if i scrolled in the tab bar, the tab icon and text would remain locked in place in the display while the other tabs moved behind it.

The main Firefox window also lost the minimize, restore, and close buttons. The only way to make the tabs work was to close Firefox and relaunch it.

I noticed this happened only after any app in the OS went full screen, be it a steam game, or another Firefox window, or a VLC window, or anything else that I did that made an app full screen in any of my monitors.

I am using Ubuntu 24.04 with KDE Plasma 5.27.12. Kernel is 6.14.0-29. Display server is Wayland.

Initially I thought this could be a problem with the snap version of Firefox, so now I've installed the deb package, but the problem remains. Firefox is the only app which presents a problem of any kind when any window goes full screen.

Here's a video showing what the problem looks like, in case my description was not clear. The ghostly tab in this video is the chess.com home page and you can see it as the third tab from the top right of the video, and it remains in that position as i scroll the other tabs, completely unselectable with the mouse.

Any idea of what could be causing this issue to appear?

Thank you!

Hey everyone, I recently switched to Firefox and have been running into an issue: when I scroll down with my mouse wheel, the browser sometimes jumps back a page as if I had pressed the side mouse button.

I’ve tested my mouse in other apps and browsers, and the issue doesn’t appear anywhere else, it only happens in Firefox, which is confusing. I’ve tried looking it up but haven’t found a solution.

Has anyone else experienced this or know what might be causing it?

Mouse is Logitech G502X Lightspeed

I changed my primary AND secondary emails of my Mozilla account (in Firefox' settings), as the old one was part in many data leaks. When accessing the account settings in Firefox, all is well. BUT coincidentally, after activating Mozilla Monitor, I saw that my OLD email is STILL saved on the settings page of www.mozilla.org/de/newsletter/existing/?fxa=1 (see screenshots).

Also, when trying to login using the DELETED, old email (bum*******.de), Mozilla tells me "must use primary email to login", meaning, they still didnt really remove that one!

Why is it still there and why didnt Mozilla change it?? I want it GONE!

I have the current version of Firefox browser. Every time I clear the browsing history, I am being logged out of my Google and Microsoft accounts, which is forcing me to go through the tedious 2-step verification process to log back in. This was not occuring before. Please fix this annoying and time consuming bug!

Dear programmers! Firefox has been buggy since at least mid-May! You can't upload videos to Youtube with it! The upload stops at zero percent and doesn't move any further! The problem started with version 138, and it's currently the same with version 141.0.3! My operating system is Windows 10 / 64 bit. I was previously advised to delete cookies, but that didn't work either. Uploading videos works with other browsers. Sometimes, you can't even post a picture attached to a comment on Facebook. I was able to do that with another browser. The video upload error occurred earlier, with version 131! It was fixed shortly after that! I would like this to happen again! It's very annoying that this error has been around for months and hasn't been fixed!

I have an extension called Last Pass installed. Is it possible from Mozillas side to see when it was installed please? I think this would have been installed on 12th July 2022

Also does it sync passwords on phone with desktop, as it seems to have synced a password for a site that I do not recall using on my laptop

I am a Firefox user for the last 20 years. I frequently use Google Translate, and I depend on the voice-to-text feature. However, when I try to use it in Firefox, I get the message: “Voice input is not supported on this browser.”

Because of this, I am being forced to switch to Google Chrome, which I don’t really want to do. Is there any workaround, add-on, or upcoming plan to bring proper voice input support to Firefox?

THE ISSUE: When opening Firefox, (Attachment #1 - below) appears. Seems to have nothing to do with any reality . . . as when I check in SETTINGS (Attachment #2 - below). 1. So, who's telling the truth? 2. How do I stop the popup (Attachment #1) from making it's nagging, inaccurate appearance?

Thank you / Nels

I'm used to use the sidebar history to open previous links for a variety of reasons. You used to be able to click or middle mouse click the links to open the tab in the current or a new tab. But it seem now i can only left click the links and it opens them in a new tab regardless. Right clicking only allows you to open the link in a new tab or a new (private) window.

Is there a way to fix this? Please help.

Thanks

I have option turn on to open new tab for a new webpage. I want it to only open new tab for a new website, but not with ever webpage I look at at the same website. Can you help?

Hello! Very new to Linux but got a new laptop and installed Ubuntu on it. I've run into some issues logging into sites (specifically iCloud) and somewhere I saw someone say they fixed it by installing Firefox via the .deb package rather than through snap, as it's installed by default. Following the installation instructions here: https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended I've run into a roadblock with adding Mozilla APT repository to sources.list. Copying the instructions for Trixie and newer, I've run into an issue where it's giving 'permission denied'. As I'm new to Linux, I'm not really sure what next step to take, short of just typing "sudo" everywhere to try to get it to accept it. Please assist! I would be grateful.

Each day I get an email from Microsoft OneDrive with photos of the day, titled On this day"'. Clicking on a button titled "View all memories" on the email causes the photos from that day to appear as a new tab on Firefox. Perfect. Until a couple of weeks ago.

At that time, clicking on it caused the new tab to appear but no photos are displayed. The screen looks as if it's trying to load the pics, but nothing shows up. When I open up the OneDrive website directly, I can click on "Photos" and see ALL photos in my cloud account, and there is also a row at the top under the title "For You" which shows several clickable buttons titled "September <XXX>", "A new trip", "Revisiting <month XXX>", "Last week", etc. Clicking on each of those separately yields the same result as when I clicked on "View all memories" from the original email, which is that nothing is displayed but it appears to be trying.

Below the "For You" row is "All Photos" sections which has everything, but not organized like the "For You" row. It simply is the entire set of my pictures from which the "For You" buttons do their selection from.

I exchanged emails with the MS OneDrive support over several days, who made numerous suggestions, but none worked. We did determine, though, that the photos do appear seamlessly if I switch to Edge as the default browser, but I want Firefox as my default.

Because the photos did appear under a different browser, they suggested I contact Firefox, which I'm doing. And this is after I've tried all the suggestions contained in a google search I entered as: "firefox setting to allow microsoft onedrive photos of the day".

Understandably, I'm very frustrated and appreciate any suggestions anyone can provide. Thank you.

Firefox told me to update Firefox. I had to get help from Apple support to do so. Now the new version takes forever to load anything. I can't read comments from other people on my Facebook posts. Amazon takes forever to show the products that I am looking for. I saved both versions of Firefox when I updated, so how do I find the previous version to use? It was much better on my computer.

Before Firefox added Tabs, I added the Simple Tab Groups extension. How do I move the contents of my many STG tabs into Firefox tabs? Also, there are different colored boxes on my top bar, with my STG tabs, and hovering yields "Unnamed Group Expanded/Collapsed." are these FF tabs?
