Firefox 技術支援討論區

I was having issues with my laptop so I decided to do a System Restore to a previous date. Once completed, I opened Firefox and tried to restore previous sessions, but none were found. I also noticed that the shortcuts were blank, possibly uninstalled. I clicked on shortcuts and nothing opened. I downloaded Firefox again and reinstalled, but now I cannot restore my previous sessions. I tried to restore going to History>Manage History>Import and Backup>Restore>Choose File and selecting previous.jsonlz4 and recovery.jsonlz4 file with a date from last month, but again nothing happens. I searched around for answers, but only came across instructions to compress jsonlz4 file and decompress using mozlz4 without any instructions on how to use it.

What else can I do?

Windows 10 professional for workstations Firefox build 126.0

My browser auto updated today and after the refresh I found that the history under the address bar has been broken. It now displays only in part and over top of the address bar itself which as you can imagine is unusable. See image attached.

I entered troubleshoot mode and the problem went away. So I disabled all my extensions and addons, but the problem persists (when not in trouble shoot mode)

Any idea what could be causing this? It is hampering my ability to do my job.

I have enabled my new Theme but it keeps defaulting back to my old Theme. I have tried closing Firefox and opening new tabs. Opening a new tab also changes it back to the default theme. I have sent an image of the old theme. The new theme is Aurora Australis. And the second image shows this Theme enabled. What gives? Carl

Firefox updated last night while my headphones were plugged in. Now I cannot get website audio through the headphones in Firefox. None of the solutions from help forums have worked. Audio settings seem fine and headphones work on other browsers.

Hi there,

I read books using Amazon Kindle's cloud log in. After installing Firefox 126, I am no longer able to open books on my last page, I cannot turn pages or even open my notes. I tried using Kindle cloud on other browsers and everything works fine.

Any idea why my Kindle cloud functions are not working on Firefox?

Firefox browser doesn't load youtube's content, showing only grey for videos and text. The browser console shows a number of errors (I've attached a screenshot of the console). Even playing a YouTube video linked from a web site plays only that video. All other content is greyed out. Safari loads YouTube without problem. iMac 2017 OS is up to date, as is Firefox. What do the errors mean, and is it a problem with my settings? Thank you for any help

Video is stuttering with latest update. This just started today, Ma7 17, 2024. I went to a different browser to confirm that it is firefox. This confirmed the issue. I checked the settings and I have selected everything as indicated in the help files. I tried turning off enhanced tracking function and I selected allow video and audio auto play. It still happens

Hi After the latest update, the address bar dissapears everytime I click on it to type in an address. It gets hidden behind previous addresses I visited. Completely unusable. I have no idea why it is so bad and how to fix, please help. Thanks

When I restarted my PC and opened Firefox only 1 tab Open previous windows and tabs. All the other 6 disappeared. I opened 3 additional tabs, closed Firefox, and reopened Firefox and only the one same tab was there from the previous session. Why does the feature not work properly?

I just updated to the latest version of Windows 10, and now when using Firefox (126.0), the url dropdown menu rather than dropping down now "floats" over the browser window with the top cut off. The top url is still there, and I can navigate to it using the arrow keys, but it doesn't show. This is new as of this morning, when Windows updated. No issue in other browsers.

As of Wednesday afternoon my internal/system mic and speakers are no longer working with FireFox. Geek Squad says it's a problem with FireFox. I'm running Win11 on a Dell laptop that's about a year old. Firefox is up to date, and Windows should be as well.

There is a display issue when I search anything in the url bar. It goes up the window, and disappears completely if many suggestions are made. The issue disappears when in troubleshooting mode. I disabled all plugins, changed the theme to no avail.

Getting application errors on some sites – but the same site works in other browsers. This has been happening over the last couple of weeks – getting application errors on some sites but not in other browsers. On the example shown I see the login page flash briefly then replaced by the error.
