Firefox just keeps getting slower and less responsive. I've cleared the history etc and run my Avast cleanup premium which helped a little, but the other browsers just put it to shame. I hate to switch because I love the user interface, but............ its just frustrating. Windows 11 latest updates.

Firefox (current version:137.0.2 64-bit) does not allow drag from outlook on the web and drop on windows 11 file explorer. It shows a forbidden sign when i am dropping on file explorer.

How this problem can be solved?

I have a new desktop i7 computer with 16 GB of RAM. Why are my Firefox browser screens locking up? I'm running Windows 11 Pro. I don't have this problem with Chrome.

I have tried everything. I've gone into the permissions, I have it set that everything is allowed. I reset and forgot the sites multiple times, zoom and Google Meets, and when I reload still the same issue. It says I do not have a camera. The camera works for both Edge and the camera app on my laptop. I even checked my settings on my laptop, and Firefox has permission to access my camera. However, in the camera request history, it does not show that Firefox asked for access to my camera. It also says the last time it accessed my camera was last year, but I have been trying to get it to work this entire time. I am updated with Windows 11 and the latest update of Firefox. How do I fix this? Is it an issue with Firefox or Windows?

Using Firefox on Windows 11 I cannot access DocuSign files. I need to send a form to an on-line bank and want to use the DocuSign function. When I click on that option on the site all that displays on the screen is DOCUSIGN but the feature doesn't show. I tried turning off security addons such as Privacy Badger and Ghostery but that didn't help. I can get to the feature using Edge but I really don't like using that. Is there a setting that I've missed that may cause the disconnect?

The generic DocuSign site it https://powerforms.docusign.net/. Any other details in the URL I used refer to my bank and the account, so I am not including that information.

Thank you.

I would like to open attached docs and print them. They are appearing all black with some verbiage, or multiple pages are all white. What is going on? How can I fix this? Step by step instructions, please. Technically challenged. I do NOT use cloud. will not be using it due to privacy and hacking issues. I save everything to my harddrive.

I have ended up with five different calendars. They all have different names--probably because I really don't understand how Thunderbird organizes things in regard to the rest of the internet. Several people in our household share calendars, to keep track of events, tasks due, and medications.

So how do I consolidate all the entries in all of these calendars? I have tried syncing, but that doesn't seem to work. How can I know that when I enter a soccer schedule on (one of) my calendars, it will end up on the calendar that my wife uses to print out our family weekly schedule?

Hello, I am experiencing unexpected behaviour with local storage in Firefox Portable ESR 102.1.0 on Windows 11. In particular, the data is not deleted as expected after closing the application, even after clearing the cache in my code, the data persists when I open the application the next time. This behaviour is observed under windows10 but is common under windows11.

I suspect that this issue may be related to:

• Interactions between Firefox Portable's cache management and Windows 11's system-level caching
• Specific behavior of the ESR 102.1.0 version on Windows 11

I would appreciate it if you could investigate this issue and provide any insights or solutions.

I currently use Norton360. I attempted to use their Driver Updater and later Utilities software. Neither worked to any satisfaction. Does anyone know of an all in one program that satisfies these categories using Windows 11?

Following a recent update of my bios (AMD Ryzen) of my PC the on-board sound system failed. I chased down the issue, got a sound card to circumvent the on-board circuits, and had sound once again but for my FireFox (Ver 133.0.3, on Windows 11 Home, Ver 10.0.22631 Build 22631). Testing with alternate browsers (Edge, Opera) the sound works, as do my downloaded games and music but no joy with FireFox.

My question: Is this a known issue being addressed for a future update or are my circumstances an outlier issue?

Environment:

  Windows 11 Pro, Version 25H2, Updated windows (include KB5074109) on Jan 16, 2026.
  Firefox version 107.0  

Issue:

  Firefox freeze shortly (e.g. after play YouTube video for less than a couple minutes, just browser YouTube videos for a while, or just open about:preferences page).
  
  I installed  Firefox 147.0.1. Same issue. 

  Hover cursor to Firefox, it becomes busy (blue spinner)

  Note: Firefox works fine before the windows update. Chrome exits suddenly after the update too.

Task Manager: shows 15 FireFox processors with 0% CPU usage.
