Firefox コミュニティフォーラム

Since I started syncing Firefox on my IPhone, every time I close and open my Windows desktop Firefox, my sync account gets disconnected and I have to login in and put the annoying verification code every time. It gets disconnected only on the desktop side and not on the Iphone. It's pretty annoying. Any ideas why this happens? Thanks in advance.

I had to do a clean reinstall of MacOS. I've copied my old profile info from Time Machine to /[user]/Library/Application Support/Firefox/Profiles, but when I open Firefox, it doesn't find the data. What am I doing wrong?

Respected Sir/Madam, I found a problem to use Mozilla Firefox (137.0.2 (64-bit)) on Windows 10, problem shows in attachment.

Already uninstall Firefox and reinstall it but problem not solved. After restart PC Firefox works and it browsing speed is very very slow but after close Firefox problem start again.

Please give me the solution. I am a die hard lover of Mozilla Firefox.

Hi everyone,

I’ve recently started playing Krunker.io (a browser-based FPS game), but I’m facing a lot of lag and stuttering in Firefox. The game runs fine for a few minutes and then randomly starts slowing down — especially during fast action scenes.

I’ve tried the basic stuff like:

Updating Firefox

Using private window mode

Closing other tabs

Enabling hardware acceleration

But the issue still comes back, especially when I play for more than 10–15 minutes. Has anyone else experienced this with browser games on Firefox? Any tweaks or settings you recommend to improve performance?

Thanks in advance! 😊

As the title suggests, I've found that exceptions added for 'Enhanced Tracking Protection' simply do not function in a private window; they're entirely ignored. The discovered 'Tracking Content' (from shield in the address bar) will list the exact domain that's whitelisted and the network tab of the devtools will label the URL as blocked due to tracking content. Obviously this is wrong, that short of per-window type settings, this should be global (and makes no sense to differentiate anyhow).

Switching to a standard window fixes this, however, and the exceptions are taken into account.

Firefox is not loading on my desktop full sceen. I can see a small page minimalized when I put my curser on the Firefox icon. This has happened once before and I had to uninstall and install and I lost a lot of settings doing that. Please advise. Picture on the left is what I see, not the other.

When I go to the task bar and click on firefox the only thing that comes up is, top left corner it says new tab but nothing opens after that, just blank screen. I want to use firefox as my browser but if this continues I'll have to use a different browser.
