Firefox 技術支援討論區

Hi,

Occasionally when downloading files on Firefox, they'll freeze completely (often at the very end.) There is no way to pause or cancel the downloads, except to restart Firefox.

When I attempt to restart Firefox, it closes the browser window. However, when I try to reopen it, I get an error message stating that Firefox is running but not responding. The 'Close Firefox' option does nothing, except make the box pop back up a moment later.

I can't kill the Firefox process in Task Manager or Process Explorer, because it says access is denied. I can't kill it using taskkill in command prompt because it says there is no running instance of the task.

The ONLY thing that seems to help is completely restarting the computer, which is getting frustrating to do several times a day.

I can confirm Firefox is up-to-date. Any tips are appreciated, thank you!

I'm using Firefox with Google as my default search engine. When ever I try to type in the Google search box, what I am typing appears in the address bar. I want to search in the Google search box as it is at eye level for what I am doing. I have tried all sorts of ideas from the web to fix this but no joy. Does anyone know how I disable this? Thank you

Had to replace FF with Chrome in order to play DRM content on my W11 laptop. I get message saying you are downloading remedy, but nothing ever changes. Would prefer to continue 15+ year relationship with FF, but seems like youre abandoning capabilities for DRM video content?

Is there a way to use the default xfce windows instead of firefox`s own? I mean I have my own setting in the xfce window manager that are not applyed to firefox. fo example: I unchecked Raise windows when clicking inside application window, that is not applyed to firefox, I also have a context menu when right clicking on other windows title bars that I can customize, In firefox I have something total else.

Hello,

I am experiencing a persistent issue with web browsers on my Lenovo Legion T5 26IAB running Windows 11 Home. Regardless of whether I use Mozilla Firefox, the browser frequently crashes. This happens at least once a day, and it seems to be unrelated to the number of tabs open or the specific content being viewed. I did the help -> diagnose mode without plugin and it crashed too, im not sure what this is realted to.

The crashes often present with an error message suggesting a failure in the new tabs or trying to load a old one, despite the fact that my system's RAM usage is typically around 60-70%. I have already updated the BIOS, Lenovo drivers, and NVIDIA graphics drivers, but the issue persists.

I'm seeking advice on what might be causing these browser crashes. Is it possible that there's a compatibility issue with Windows 11 Home? Could it be related to the graphics card or its drivers, even though they are up-to-date? I have not changed the power cable from my old PC; could this be a factor?

Any insights, suggestions, or similar experiences would be greatly appreciated. I'm trying to determine if this is a hardware issue, a driver conflict, or something else entirely.

Thank you in advance for your help.

Some websites, like my bank, don’t let you paste into the password field. I don’t want to manually type in the password. I found a workaround:

1. Go to about:config
2. Search for dom.event.clipboardevents.enabled
3. Double-click it to change the value to "false"

But the problem is that pasting into a google document no longer works. I have to revert the value back to “true” to get copy-pasting working in a google document.

Is there a way to have the best of both worlds: paste in google docs and paste in sites that block pasting, like my bank?

I want to find to get rid of this or find the source of this so I can delete it.

In "about:policies" there are 2 Active Policies: "DisableTelemetry", and "DisableDefaultBrowserAgent" Also, in "about:policies" I'm not sure if it's related, but there is a long list of policies there too.

I just noticed today that my New Tab Page is now displaying an old set of icons (are they called bookmarks?) It might be associated with the recent update to v121, but I have lost several newer pinned icons. The display today is shown in the attached image, and I have drawn a red diagonal through icons that have not appeared on my New Tab Page for some time. I don't have a list or image of the recent ones that are gone missing.

I'm sure I'll eventually find and replace the ones that I lost, but this is just embarrassing for FF, which I use for just about everything.

If there's a way to revert, I'd like to know.

Dear Community,

I am trying to download a large file. Am on a course, and the main tutor has given the group a file to download. Have tried downloading this 5 times, but get little luck. The file that I would want to download is 8.5GB, and the furthest I get is about 4GB.

I have 2 questions about this.

1) I seem to have a very 'in and out internet connection. It seems to go down at times for no reason, cutting off the download. Is there anything I could do about this? How could I troubleshoot this, please? 2) Does anybody know of any special tools that I can use to download in a more efficient manner, please? Perhaps an extension for Firefox might be able to do this, perhaps? Kind Regards to Anyone Answering this Query, Marek

There used to be a box to write tags as you can see here: https://support.mozilla.org/en-US/kb/categorizing-bookmarks-make-them-easy-to-find?redirectslug=Bookmark+Tags&redirectlocale=en-US

What happened to it? When it was deleted? Why? Is there a way to restore it?

My Firefox Menu dropdowns disappeared so I read that you should hit "alt" button to restore it. It only works temporarily and dropdowns disappear every 5 minutes. And Firefox is not saving passwords when I visit websites. (I checked and I still have all my passwords saved in Firefox Settings.) And I have "Fill usernames and passwords automatically" checked in Firefox Privacy Settings.

I started having problems with Firefox when I installed "Hide my IP" add-on because I wanted to change my IP address. I added it because I was getting website advertisement popups telling me to buy a VPN. I disabled "Hide my IP" yesterday. And I'm also getting more website popups now. Do I have to tweak Firefox Settings to stop all of these problems?

Firefox has been up-to-date and I'm using Windows 10.

I have had two issues since transferring to Firefox from Chrome. Both result in error messages:

1. I have a Revolut bank account for which I get an error message (see below) when I try to log in. When I click the 'Restart Log In' button it retruns me to the orginal log in page with my name and on clicking this I am logged in. I have contacted Revolut support but they say the issue is with Firefox.

2. Other issue I have is that in trying to access some websites I get a messaeg saying that the site cannot be verified with a button to 'Try Again'. Once I click this button I can access the page.

I can work around these issues but they are annoying.

Firefox often display messages at the lower right corners - only from selected sites.

It drives my crazy - because I have to click on each and ervy one.

How can I select the sites which are displayed or can I shut them off all together ?!?

Please advise !

Goodd day from UK I run firefox esr 115.9.1 and find the the F5 refresh key does NOT refresh the images. The same applies when using the "reload" icon in the menu.

Reading other posts, nothing seems to apply here.

There are NO add-ons at all and everything is cleared on close. The text DOES seem to change.

As a web developer checking updates this is extremely annoying as only hope is keep closing the browser (to clear everything) and restart - the loads new images etc.

I use several versions of Firefox (2, 20, 56) to ensure compatability with olf browsers and it seems to be only those over 100 with this issue.

Does anyone know if this is a "feature" or a"bug" and is there any simple (!) way around the issue?

Thanks

p.s. ALWAYS happens, not intermittently

PR_END_OF_FILE_ERROR how do I get rid of this error that keeps popping up when I attempt to launch Amazon.com I have never had this happen before..... it just started about a week ago.

I use a password manager. Many of the web-based services I subscribe to use my email address as my user name - this is quite common.

When I am trying to login to one of these pages, your "Let Firefox hide your email address" message pops up over the selection box from my password manager. There doesn't seem to be an easy way to remove your message - which, in this context is totally inappropriate - but your message prevents me from logging in to my account when I need to choose between identities (example, work and personal).

Can I turn these messages off? or can you add a simple "X" to the window so I can close it without that action being picked up by my password manager?

How do I delete, remove, or otherwise disable that garbage "review checker" from the latest firefox update. It's useless, un-needed thing that I don't trust.

option to OPT out REMOVE/DELETE or completely DISABLE!

Hi,

I've been using the following in userChrome.css for many years

1. menu_close { display: -moz-box !important; }

to restore "Close Tab" in the File menu, based on cor-el's response regarding restoring menu_bookmarkAllTabs here:

https://support.mozilla.org/en-US/questions/799856

This stopped working some time ago and I am finally getting around to asking why.

I do have toolkit.legacyUserProfileCustomizations.stylesheets set to true, and other items in userChrome.css are working.

I am using 121.0 at home and 115.0 ESR at work and see the same (i.e. no "Close Tab"), in both cases on Debian testing. I do see this menu item when using the keyboard to open the File menu.

Any idea why this no longer works?

thank you, Greg

All of the sudden I am getting an "Acess Denied" message from Quickbooks online. The error message is immediately after I type in my login ID and hit enter. It doesn't even let me get to the password input screen. This started on Thursday afternoon, but was working fine Thursday morning.
