Firefox Community Forum

This has been asked before here, but it seems currently there is no solution:

Firefox's default behavior when using the mouse middle-click on an empty area of the tab bar area will create a new tab; I don't want this behavior. How can I disable it?

On the posts I found here, they mention using UserChrome.css, I enabled it and tried, doesn't work. custom styles are enabled but not disabling this feature.

I use DisplayFusion on my multi-monitor setup since years, and middle-clicking a window title bar or Chrome tab bar or Firefox tab bar will move the current window to a second monitor.

Currently with Firefox, middle-clicking the tab bar will move the window to the second monitor AND open a new tab. I use it a lot with YouTube, so when I move a playing video to the second monitor, I get an empty tab with audio in the background.

I recently moved from Chrome to Firefox, but this is driving me crazy.

iCloud has stopped signing in on the Firefox browser for Windows. I contacted Apple Support and they told me that this is an issue on Firefox's part, and told me to try signing in the next morning and they guarantee it'll work. It did not. In fact, it has been over a week, and it still does not work.

When I enter my Apple ID and Password, the website gives me an error "Failed to verify your identity. Try again." The website does NOT send me to the 2fa screen, yet it still sends a 2fa code to my iPad nonetheless.

As Apple has said this is an issue on Firefox's part, I am posting this here. Attached is a screenshot of the error.

Firefox is no longer saving all my history. OR, I can't find it. I can't find it because: HISTORY/SHOW ALL HISTORY is now only showing "today". This occurred with v133, but I do not know if it occurred with any given update. I updated to 134.0.1. That did not fix problem. I have not tried regressing.

In the past, I was able to save YEARS of history (although I sometimes created a new profile to restart the history file due to its size).

1. I was using the "DYNAMIC HISTORY" addon, which worked fine for years. When I found Firefox was showing only the current days' history, I disabled that addon. Didn't fix anything.

2. "Delete cookies and site data when Firefox is closed" option IS NOT SELECTED. NEVER HAS BEEN

3. OTHER SETTINGS: no - Always use private browsing mode yes - Remember browsing and download history yes - Remember search and form history NO - Clear history when Firefox closes

any suggestions or help would be greatly appreciated. I am also baffled: googling this problem comes up empty handed.

I have just re-installed MW due to probs using the original one, but now I cannot enter my registration code,(life time) there is no where to do so it seems,have looked everywhere?

After the Dec 10 update to 133.0.3 (aarch64) on my MacBook Air macOS 15.1.1, all of the menu keystroke options are greyed out. Also, in Settings, Firefox is selected as the default browser, but the option is greyed out so that it is not possible to change. I've disabled all add-ons except my password program, tried troubleshooting mode, and restarted.

Recently starting having the issue where some whites and the tab icons appear washed out and even glitched out and pink when using my PC. I haven't made any significant changes to my system as far as I recall.

Colours in other browsers and applications are effected. Going to the same webpage on both Brave and Edge shows the whites correctly. On all the games on my PC there are no glitches in colours.

I have tried a few fixes already: -Removing and re-downloading GPU drivers - Fixes the issue temporarily. After about 1 day the issue comes back. -Re-seating the GPU - No fix. -Turning off colour override in Firefox - No fix. -Uninstalling and reinstalling Firefox - No fix.

If anyone has an idea or knows the setting that may be causing this problem I would really appreciate it.

So i am using ReseourceOverride AddOn to debug a js library on standard install of firefox. This works by using the site as normal but resource override has instruction to replace request for the library on server with one requesting it from localhost. This used to work without problems. However today i noticed that breakpoints aren't getting hit. I have downgraded to version 132.0.2 and breakpoints work once again. I think this has something to do with debug sources, since the load process adds 2 sources, webpack containing uncompiled code and where i set break points, and webpack-internal which i think is built js library before getting minified. Links to exceptions in console also dont work instead of linking to webpack seemlesly, the adress says webpack-internal and link open a new window and complains that the adress is nonsense (see attached images)

Thatnks for the help

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

Possibly there was an auto update of MOZILLA FIREFOX on our DELL LAPTOP (Windows 11). Now, we cannot get a Mozilla window to open - due to error message:

XUL Runner Error: Platform version '118.0.1' is not compatible with minVersion >= 118.0 maxVersion <=118.0

Can someone please help us get back to a previous version of Mozilla Fire. Perhaps it is a Windows error. I have no way of knowing. Please help me. My email is: [removed email from public] Thank you.

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?

There is no audio on any website in Firefox only. I'm using Windows 11

1. Numbered list item When a video is playing there used to be an audio icon showing the tab is playing audio, this does not show anymore.
2. Numbered list item Firefox does not appear in the Windows volume mixer
3. Numbered list item The Firefox Task Manager Utility 'Windows Media Framework Audio Decoder is always idle.
4. Numbered list item I've restarted the Windows AudioSrv service and Windows explorer process

Nothing works. Please help.

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.
