Firefox 社群討論區

I found a potential flaw that can allow someone to gather all passwords saved by a user. It's pretty simple to explain, but also to exploit, so I don't want to do it publicly. Is there some specific team member that I should contact directly?

Hello everyone! My problem is that for 5 days now and without doing anything in my pc, right click in the main page of firefox is not working at all. In every website i visit i can not right click. It works only in the menu bar and address bar, not in the main page. Thanks!

Recently, I have not been able to upload a video to YouTube. When I try to upload it, the upload is stuck on 0%. I tried another browser, and it worked fine. This has not been a problem until. I have uploaded many videos. The last time was about a month ago. So, maybe there is some problem with an update. Does anyone else have this problem or know the solution?

I'm using the latest Firefox on Win10, with a fairly powerful laptop (64 gb RAM, intel i7 2.3 GHz chip), and for about a month now, whenever I use it, it uses so much CPU all the time that my laptop is overheating (slight hyperbole, but it's definitely churning the fans a lot, and the area around the keyboard gets hot to the touch). Sometimes it uses up to 45% CPU, and over 20% memory!!! (as reported in the task manager) Usually around 20-25% though. While Chrome, at the same time, is using 0.1%. It's not just when starting up, either, it's continuous during use, until I quit Firefox.

What the h*** is going on?!? I've tried the troubleshooting steps, but it remains crazy regardless of turning off extensions, and I'm just using the default theme. I notice it's mainly when loading images, like on social media.

This is insane. What is happening. Can someone help me?

A white horizontal line in the top of the screen, whilst watching movies in tv5mondeplus.com. This issue happens when installed the recent update 129.0.

Tested in other browsers and doesn't appear the white horizontal line on top.

Hello=)

I am using Firefox v128.2 esr 64bit on big sur 11.7.10..

In firefox there is always this white line on top of the screen when fullscreening a yt video... (but also partial bars in other situations-randomly) (temp workaround : cmd+up arrow . But, whenever you pause or press something it reappears.

Can we please implement a more elegant solution?

Thanks a bunch , dear Mozillians=)

Have an excellent day=)

Every time Firefox updates it keeps re-enabling settings on its own.

Specifically 2 settings on the general tab keep enabling themselves in the "browsing" section, "Recommend extensions as you browse" and "Recommend features as you browse"

I have disabled these settings dozens of times now, and every time Firefox updates it keeps re-enabling these 2 settings on its own.

Just now I updated to v128.0 and these 2 settings turned themselves on again.

Why is Firefox not respecting my settings? Why is Firefox allowed to modify my settings without my permission?

I have deleted and reinstalled Firefox already. I don't use profiles and am not signed into the browser, so no settings are getting carried over that way.

I keep getting the attached message when I sign into my bank. This just started yesterday (9/4/24), but when I sign in with another browser I don't have a problem?

Hi, I need to reinstall my windows, I forget my Firefox account and create a new one and lost all my saved password. Is there any way to retrieve it? I create Firefox account ofc to save the password, but if the account cannot save the password whats the point to create an account.

Hello, I checked my RAM and has no problems, but my Firefox crashes every time, with every tab.
