Firefox 技術支援討論區

I've received my new PC and will be migrating from my old PC (Windows 10) to the new PC with Windows 11.

I use local folders in Thunderbird to keep various projects separate and more easy to manage. I have copied the current Thunderbird profile on to an external hard disk, I have found the location of the local folders and they reflect the structure in the Thunderbird screen I see. Thunderbird has been unstable for a few weeks so I would prefer a clean install but don't want to lose a lot of content that I still need.

1. Is there a way to copy over just the local folders, eg export them, rather than the whole profile? I deliberately haven't cleaned the server recently so that I can get back emails that still are in the in_tray but once they are in local folders they disappear from the Yahoo server. 2. Is there anything else significant I should be aware of before migrating? There is a backup on Mozilla but I prefer a clean install.

Thanks in advance,

Anne

looks like a problem with Firefox as no problem when using a different browser e.g. Opera. Also cannot log onto Nextdoor.co.uk using Facebook to log on. Again works fine on Opera

Any links from rcsearch.ru to aliexpress is broken in firefox, but works in another browsers. For example click any aliexpress link here rcsearch.ru/-c48920.

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've been having issues with the websites that I commonly go to no longer appear on the autosuggest list. Websites I haven't gone to for ten years appear when I type in a given sequence rather than more common ones. Website that I go to every day no longer appear.

Multiple websites suggest this sequence:

I follow the "clear all.." and nothing changes. How can I start anew and have FF re-learn my url history?

Dear all,

I don't know why the file content will be change HTML content when I use the Firefox to download it.

As of an hour ago suddenly all of the usual suggestions and autofill with bookmarks in my address bar are wrong and out of order. I didn't close out of or update Firefox, I was just browsing online. I didn't change anything in my settings or have opened that up in days at the minimum. I cannot figure out how to either revert back or tell Firefox to not show me these choices so I can get my old ones.

I'll give an example: When I typed in "ma" it would show me mangadex.com, which I often go to. Now when I do it not only is 5th on the list it shows up and fills in "https://www.manticgames.com/", which I don't have that specific page bookmarked. I have "https://www.manticgames.com/games/kings-of-war/" bookmarked, but not that homepage. But now all of a sudden it is showing me the homepage of that site when I begin to type in "ma".

This is incredibly irritating and I have no idea why it's doing this at me out of nowhere. I don't want about anything showing up besides my bookmarks and specifically only the pages I bookmarked.

There used to be 4 root folders in my bookmarks toolbar on PC: bookmarks toolbar, bookmarks menu, other bookmarks and mobile bookmarks. Recently I noticed the "mobile bookmarks" folder is gone. That is where bookmarks saved in the default folder on mobile were synced. What happened?

After the last update my primary password prompt box is outlined in red. It was never outlined in red before the update. I cannot find any information for this issue. Anyone else experiencing this anomaly (at least it appears to be one since no one has reported it). Thanks

Hello, today firefox has been appearing as a blank icon on my taskbar. I have tried solutions suggested in older posts but it did not help unfortunately. if i try to

1- right click unpin from taskbar the icon shows once more. 2- right click, the icon disappears/becomes blank. 3- click pin to taskbar, the icon remains blank.

attached is the image showing the steps i described above

I just installed Firefox v125.0.1 on my new desktop and I am constantly being harassed by Firefox suggesting "tips" to me that I don't want nor did I ask for.

Such as this example below, see screenshot. I am browsing the web and needed to open a new tab, and immediately Firefox thinks it is okay to harass me with something that I OBVIOUSLY already know...... searching google from the address bar.

So now I have to stop what I am doing to click the "Okay, Got It" button to proceed. But, that won't stop Firefox from harassing me with the EXACT same tip in a few minutes from now.....

This isn't the only "tip" it harasses me with. It's just the only one I have managed to get a screenshot of for now.

How do I permanently disable this crap?

I have been using the internet and web browsers for 30ish years now. I'm pretty sure I know how to use an address bar by now Firefox.....

I also don't appreciate being harassed by things at all. Since this does the same "tips" repeatedly and they never stop it is absolutely harassment. Why are you showing me ANY tip more than once?????

Firefox 125.0.1 update breaks all self signed certificates

After the latest auto update I can no longer access any of my management screens on my private network with self signed certificates. This is a real problem. I have attached a couple error screen grabs, but ALL of themn are the same. The information link says there is no workaround!

So how do I recover access? Chrome works just fine ... so it is def. a Firefox problem.

Firefox browser, v123.0.1, 64-bit. windows 10 Pro, 22H2.

Hello, this may not be a problem with Firefox itself at all, but I'd like to try to understand what the cause of the problem I and others are having.

I have Norton 360 installed, in this Windows 10 computer and like to use Firefox for internet browsing, it has always served me well.

I also have Norton Safe Search integrated/add-on to Firefox. This puts a red, green, or gray check mark at the end of each link that comes up during a search and has always worked before.

Recently, I've noticed that such check marks do not appear at all when doing a search with Firefox, but they are present when I do searches with MS Edge.

I am searching for a solution here, and also in the Norton Community. There are others there who have stated they are having the same problem.

Has anyone here heard of this before, would you have any suggestion as to what may be causing the lack of the Norton Safe Search check marks in Firefox searches?

Any input/suggestions would be welcome.

As you can see here, despite me setting custom colors and checking every setting i could find, i can't seem to find what will turn this white color to grey or black,

does anyone know how to fix this?

Hi there,

I'm curious if it's possible to configure Firefox on your own to make it a portable browser. Specifically, I want to disable data encryption and machine ID checks. I know that some chromium-based browsers allow you to do this through specific switches that turn these features off, resulting in a fully portable browser. While I'm aware of third-party applications that offer ready-made solutions, I prefer not to use them for security reasons. I'd like to prepare my own version of Firefox.

I understand some may have security concerns, but I know what I'm doing. The files will be stored on an AES256 encrypted drive. Could anyone share insights or guides on how to achieve this with Firefox? Thanks a lot

PS.For those who might suggest using synchronization, I assume that, similar to Chromium, Firefox can't sync all plugin settings, and for me, plugins are essential—without them, it's not really a browser.

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?
