I've had an ongoing issue with Firefox now for several months since upgrading to windows 11. When I try to copy text, or images, url's or anything really that is supposed to go to the clipboard, it copies a blank text with no data instead. I can copy text and images from other programs and even paste them into text fields on Firefox but I can't copy from Firefox to anything else and it's frustrating.

I recently got forced into upgrading Outlook in windows and hated it so I started using Thunderbird and surprisingly, I have the exact same issue there as well.

I have tried: Running Firefox in safe mode (Shift + Left Click) Resetting Firefox Switching Back to default themes Disabling hardware acceleration Updating to the latest Beta Build (v126) Running Firefox Developer edition

I really want to get this fixed and working, I don't want to have to switch to another browser =/.

When the little yellow man is placed on to the map, and a direction arrow is clicked, the view just continues to spin round. Clicking on the 'X' in the top right hand corner terminates street view. This does not happen with other browsers.

My OS is Debian 12, Firefox is the latest version 115.9.1esr (64bit).

I am using Ubuntu 23.10.1 with KDE Plasma desktop environment. Since recently I've been experiencing the following problem with Firfox document viewer: after a period of inactivity, PDFs become unreadable, and seem to cumulate everything that was displayed on screen (see screenshot). Ctrl + F5 does not help, and neither does closing the window and opening a new one with a link to the file. KDE Document Viewer displays the same file correctly.

The integrated webcam (IMC Networks Integrated Camera, according to lsusb) on my linux laptop does not work in firefox (v124). It works in desktop apps (eg webcamoid), and chromium. I've checked the permissions (about:preferences#privacy), and that is not the problem. about:support does not list the device in the input at all. I've tried using LD_PRELOAD=/usr/lib64/libv4l/libv4l1compat.so, but that has not helped. Does anyone have any suggestions?

After years of accessing www.youtube.com with Firefox with no problem, the website is no longer accessible as of yesterday. When I point my browser to that URL, I get a screen with greyed out video previews, greyed out titles, greyed out account access and a search window that does not do anything. I can access YouTube just fine with Safari. I've cleared my cache. Please advise.

Since about one year I am unable to use Japanese input only in Firefox. When I try to switch with fcitx and control+space, nothing happens. However, fcitx-mocz works everywhere else on my computer (i.e. terminal, thunderbird, other browsers, etc.). Furthermore, I uninstalled fcitx and everything associated with it and reinstalled it according to this thread: https://support.mozilla.org/en-US/questions/1367181 (just with mocz for Japanese). This also didn't change anything. Any help is appreciated! My system: Operating System: Linux Mint 20.3 Kernel: Linux 5.15.0-91-generic Architecture: x86-64 fcitx version: 4.2.9.7 Mozilla Firefox 121.0

when I click on the firefox icon to load it takes me to my home page, but within 20-30 seconds it loads firefox again. it is very frustrating when I.m starting something and firefox loads again taking me back to home page. I have to go down to the bottom and click off the second firefox. I don't know how or why this started. Thanks for any help.

I use Outlook.live.com Hotmail and recently a PopUp Message appears asking me to:

Add outlook.live.com as an application for mailto links.

Microsoft Customer Service said it was not something they initiated and likely a Firefox issue.

It does not seem safe to click on a random link like this without any explanation. Each time I log in, the same message appears.

Could someone please explain what this is for and how I can stop it from popping up each time I log into Hotmail?

Everything is gone….bookmarks, passwords, history on my desktop computer and I have no idea why. I opened Firefox and the home page was different and then noticed nothing was the same. I dl Firefox again, no help, same result. I do have my desktop synced to my iPad and laptop but I’m concerned they will import from the desktop and get wiped out. Is there a way to sync from the laptop to the desktop? I am at a complete loss on how to fix this. I do run a backup on this computer. Would that help? Restore point?

Many thanks,

when I entered this string - chrome://pippki/content/exceptionDialog.xul - I got a 'file not found' message. Is there another way to access that? I am trying to get to https//mlb.tickets.com and get this message: The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Today I completely uninstalled and reinstalled Firefox. Since doing this, the taskbar icon is not the same as it has always been.

It used to be that if I pinned Firefox to the taskbar, I would click on it and the default Firefox window would open. When the mouse was right-clicked, the icon showed there was a choice of the default Firefox window and an option for a privacy window I could choose. I did that frequently.

Now if I pin Firefox to the taskbar there is no privacy window option. If I pin the private browser to the taskbar, this becomes the default window with options for the non-private default browser available with a right mouse click.

I would like to know how to pin the default Firefox window to the taskbar and have the private window option show up when that icon is clicked please.

Thanks for any help provided with this issue.

Some webpages, that I must log in to, are coming up blank, when I attempt to login. No error, just blank white page. Two examples are paypal and textfree. I have cleared everything I can think of or find on the internet. I have refreshed and restarted several times. This has all started int he last few weeks. The two sites mentioned are ones I really need access to. I am not sure if it is my machine or the browser.
