Diễn đàn hỗ trợ Firefox

There are other threads about this, but the solutions given haven't worked for me. I'm using Mullvad VPN, and whenever it's on, I cannot search for anything regardless of my search engine, and pretty much the only website that will open is Tumblr. For anything else, the URL will be in the bar at the top, but it won't do anything beyond that; it won't even show the loading symbol. It worked very briefly when I first got the VPN, but now it doesn't. Other browsers work with my VPN. What am I supposed to do?

a flashdrive is mounting as ro, and nothing i do can fix it.

I always use the middle mouse button (pressing the scroll wheel) to open and close new tabs, but since the update, it doesn't work anymore and now types "=" if the cursor is in a text field. For context, I use an MX Master S3, mapped with Logi Options+.

Anyone else having this issue? How do I roll back to the previous version??

SOLVED: It was a bug with Logi Options+, not Firefox. When I hovered over the tab for the presets I had for CaptureOne, I noticed it also said Firefox. So seems something weird happened there. Deleted that preset and the issue in Firefox went away.

I couldn't find a way to delete this thread, though.

This issue came up in early April 2025.

Programs other than Firefox (e.g. Edge, Media Player) behave normally: when playing sound, if nothing is plugged into the 3.5 mm jack, the sound comes from the desktop's external speakers; and when an audio device (speakers or headphones) is plugged into the 3.5 mm jack, the sound instead comes from that device.

Where as Firefox will play using the internal speakers as expected, but when a device is plugged into the 3.5 mm jack, no sound signal goes to that device.

It seems then that the hardware is okay, and the problem must lie within Firefox, or within a Windows setting that is very specific to Firefox.

The sudden onset earlier this month may point to either a Firefox update, or (less likely) a Windows update.

When I play games like classic.minecraft.net or krunker.io, the pointer speed is very slow. So I would like to know if there is a way to change the pointer speed of firefox.

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.

when I try to use face book messenger for video calling I receive the message "video calling is not supported by this browser" I have never had this problem before I agreed to Firefox as my default browser. Is Firefox not compatible with face book?
