Firefox Community Forum

When trying to launch the browser from a network folder, I encounter the errors shown in the screenshots. If I launch the browser on one computer, everything is ok, but if I need to launch it on at least the second one, I encounter this error until I close the browser on the first one. I don’t know what could have happened, because I didn’t touch the configuration and everything worked fine for us last year. Nothing was updated or changed. Firefox Portable ini file configuration:

Firefox tries to install helper each time I try to open Firefox. It seems to install and then repeats each time I try to open the software. If I cancel it will not open either.

A file called 'Pending Pings' appeared within the folder in which my Firefox installation is located. I last used Firefox on May 14, 2025. I don't know how it appeared as I disabled automatic updates and made it so it would ask me if I wanted an update, so I do not know why it is.

为什么 Firefox 115esr 会把 User Agent 中的 Windows 版本号强制设为 Windows 10？

我是在 Windows 7 下使用 Firefox 115.xx.x esr ，不知从哪个版本起发觉 User Agent 中的 Windows 版本号强制设为 Windows 10 ，请问这是为什么？

I am using Firefox 115.xx.x esr under Windows 7, and I don't know which version of Firefox 115.xx.x esr has forced the Windows version number in the User Agent to be set to Windows 10, why is that?

When I watch videos in full screen using Firefox browser, the taskbar at the bottom of the system still appears below.And it blocks some of the operation buttons, making it impossible for me to perform operations such as "fast forward", "pause", "volume control" while watching the video。 It seems that we haven't achieved true full screen display.

However, this situation does not occur in other browsers.

What's going on here?

After updating to 138.0.4 I no longer have "Recently Closed Tabs" after clearing History. Is there a way to fix this? Can I download a previous version? If so, how?

As I follow the instructions and get to the scan my PC bar code on the PC screen with my cell phone it causes the computer to respond which is only to give me an error that the PC is not paring or just sits on the same screen with nothing basically on it.

I have not used firefox in a while but am over google for good now, regardless i cant tell if this is a legits version missing a refresh page has a lock and admin badge in its place the tabs have no visible seperatiionvery odd but was wondering if there is a way to update searched and could not figure it out went thru setting might have missed it but honest should not be this hard.

Using Google Voice became unusable. Firefox too slow. Had been running just fine up till maybe a month ago when I finally gave in and allowed Firefox to update. Not knowing if it was a Windows or other issue I stupidly did a Windows reset and lost all my installed programs (including Firefox). I did a fresh install of Firefox and manually reentered passwords and bookmarks.

Ran fine for a day or two and is now again unusable. Cleared cache and appears to work OK at the moment but still sluggish.

I have noticed that Firefox has been getting too many updates recently...even as much as 2 updates this week alone. Frankly i'm sick of getting the green icons and pop-ups in the upper right corner. Is there a way in about:blank codes to turn off these stealth downloading behaviour and prompt pop-ups to restart the browser and let me just manually do it in settings when i want to but without notifications ?

When I open Firefox on my computer, I get a blank page for my home page. I have attempted to change my home page using the drop-down choices, except for blank page choice. No luck! Help.

Please create a new version of the browser app that supports the ability to use FileSystemAPI on directories, this is essential for working with a BeatBuddy project and SD cards that are saved on my computer using the online editor.
