Firefox 技術支援討論區

I am getting the error SEC_ERROR_UNKNOWN_CRITICAL_EXTENSION on every page i open. I have looked around and tried to fix it using similar error messages but nothing has worked. I have uninstalled and reinstalled but nothing has worked.

Can anyone help me as there is nothing online that i can find that will fix this.

I'm working on a new computer, as my work laptop is being upgraded to Windows 11. In the meantime, I have logged into Firefox, but none of the login info that I had previously saved is available. I can still see it on my mobile browser, but not on this new laptop.

Am I just missing a step?

At first I thought it was a facebook problem, but the issue started appearing in other places (gmail, youtube, etc). I can be writing something in a comment box, word doc, chat window or whatever and if I select some text and hit copy or cut, the entire browser absolutely locks - can't click on anything or do anything - for MINUTES at a time. There's no CPU, disk read/write, or other system usage spike to indicate what's going on - Firefox just stops and is completely unresponsive for a very long time.

This is new as of the past couple weeks, I think? I hit it once and didn't think much of it but now I'm getting hit by it daily just about because I'm more active on social media, email, and other things lately.

wtf? I have not installed any new extensions in a very long time.

Discord hyperlinks will no longer open when Firefox Developer Edition is selected as my default browser. They open fine in both Firefox, Microsoft Edge, and Google Chrome when selected as Windows 11's default browser. When selecting my default browser it would show 2 instances of Firefox Dev but after uninstalling then reinstalling it there is only one instance in the default app list. I'm not really sure where to go from here. Maybe this is an issue with the latest version of Dev Edition or is this an issue with my Windows?

Thanks

Hello,

I've recently encountered a curious issue with my Firefox browser (Firefox version 102.0, Windows 11 Insider Preview 10.0.25145.1011). At seemingly random times it will freeze for between two and five minutes (roughly). UI elements become completely unresponsive and the cursor does not update when moving over the browser window. The window will not minimize. Yet, Windows Task Manager does not report the application as being unresponsive. While never a common problem, any freezes in the past would eventually cause the Windows Task Manager to identify it as unresponsive.

I have disabled "recommended performance settings" and hardware acceleration to no avail. Everything seems perfectly normal immediately before and after the freezes, and I've yet to identify how I can trigger them. I do not recall having made any changes to my browser before the freezes started occurring, though multiple Windows updates have taken place since then. If I'm too impatient to wait I will end the Firefox processes via Windows Task Manager and restart it so I can return to my tabs without having cookies deleted. I have 13 plugins mainly covering privacy/security concerns. Is there some sort of debug tool I can engage to see what's occupying Firefox while it's frozen? I've just found the Firefox Task Manager, and will see if it can offer any additional information during/after the freezes.

Thanks, Logan

When you open the PDF with firefox, a white vertical line appears. Is this a firefox spec or is there any solution? Even if you open the pdf file in another browser, it will be displayed without any problem. If you downloaded the file, this vertical white line will not appear. If there is a setting method, give me some advice.
