Firefox 技術支援討論區

Pretty much the title. On the first launch after update, the firefox logo on my taskbar turns into a blank page icon (with the top right corner folded down) and then after I close the program there is no icon for it on my taskbar.

It only takes a few seconds to add it back to the taskbar, but it's been happening for a few months now, and with these frequent updates it's gotten pretty frustrating.

I would like to transfer my bookmarks (and my open tabs) from my Windows 10 laptop to a new Windows 11 laptop. I've looked at the questions and answers people have posted but its a complete mystery to me. I had thought that when I loaded Firefox onto the new PC and signed in, everything would automatically appear. I was successful in doing that with Chrome but Firefox is still my primary browser and I've had no luck. Any help you can provide would be greatly appreciated.

The last update a few days ago has caused Yahoo mail to not work properly. I tried using it on two others browsers & it works fine. I can't check or delete or move any emails. Can I get a link to the last version of Firefox?

What can I do to fix it? Permissions are granted, so I have no clue what's going on.

I have tried:

- Restarting the computer several times - Restarting Firefox several times - Clearing cache and cookies - Refreshing Firefox to default settings - Updating Firefox - Uninstalling and re-installing Firefox

The weird thing here is that I have not changed any settings whatsoever, and, when I try to use the camera in Chrome it works, as well as in Zoom. Now, when I created a secondary profile in Firefox, it did work there too. Any ideas as to why this might be happening?

I removed firefox fully. New profile. Disables all addons. Set the strict to standard. Still tab crashes. No idea what could be the cause? Reports below.

I use firefox to play music, so I usually have a window in the background while I do other things. When playback starts after a pause, or between songs, the playback window often steals keyboard focus. So if I'm typing in another window, I'm interrupted. Very annoying. It happens on at least youtube, navidrome, and jellyfin.

I've found a few others reporting similar issues that suggest setting `mozilla.widget.raise-on-setfocus` to `false` - but this doesn't work for me. How can I figure out what's triggering this keyboard steal so I can fix it?

I'm using firefox esr 102.7.0esr, but it's been happening for a while. I've tried the debian builds and the official firefox.com builds, same behavior. Thanks for any suggestions.

Hi,

First of all, I should ask: Is there a such feature gained with settings or addons that highlights my previous tab, that I didn't closed, but moved from to current tab?

For example: I have 20 tabs opened. And I'm lurking between them so I need to know what was the previous tab where I was before moved to the current tab.

If this feature does not exists I kindly offer to implement it.

Thanks

I tried to access a U California Master Gardener website: https://ncmg.ucanr.org/. I've accessed this for years. Yesterday, when on my Mac using Firefox, I'd get message, "SEC_ERROR_REVOKED_CERTIFICATE." (I attached screenshot.) I tried closing Firefox and reopening, cleared all browser history and other cache, and substituted "www" for "https:/" No change. I thought it was the website until I found that I can still access it on Firefox using my iPhone. (I can also access it via Chrome.)

Please advise.

Thanks! Chrissy

My hard drive died and got a new computer with Windows 10-22H2. All the data from the old PC was transferred to the new one. I use earthlink.net for email. All my bookmarks are gone. How do I retrieve them?

Hi! I recently closed Firefox like I do every single day, and when I came back all of my tabs were gone. A folder appeard on my desktop with, what i pressume, is the files for the previous session. I moved the files from the sessionstore-backups folder to the Firefox profile folder and nothing happened. Can someone please help me?

Thanks!

Some sites offer separate links for viewing and downloading. (I'm specifically interested in PDF files, but I think this question is more general.) I'm not sure how this distinction is communicated to Firefox—I'm guessing in the MIME type? But regardless of the mechanism, Firefox does not seem to offer any obvious settings that distinguish between the two cases. Are there ways to distinguish in less obvious places, such as about:config?

As a specific example: currently on a certain site when I click "View" the PDF is displayed in Firefox, and when I click "Download" the PDF is both placed in my Downloads folder and displayed in Firefox. I would prefer that the "Download" link only cause the download, and not cause the display. How can I change this without breaking the "View" links?

When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

Is there a way so that when I’m using private windows that the managed passwords will work? Even ever I’m in a private window I have to enter user ids and passwords for sites that I have the passwords saved. If I go to a normal window it works fine. This makes using private windows too annoying at times to even use.

This is a very recent issue for me. A couple of days ago "tel:" links stopped functioning. I click on a callable link and nothing happens. I checked default applications, and tel: isn't even listed there. The first time it happened there was a dialogue box asking me what application to use, but after that nothing opened at all. I build and monitor websites, so I'm constantly checking these links for functionality.

I have tried all the methods the internet suggests. but nothing works. I still have the red dotted outlines on everything. Any thoughts?

These are the instructions Type about:config in the address bar and press Return. A warning page may appear. Click Accept the Risk and Continue to go to the about:config page. In the about:config page, search for the preference accessibility.force_disabled. Observe the Value column of the accessibility.force_disabled row.

       If it is set to 1 then do nothing.
       If it is set to 0, double-click on it to open an editing field, type 1, then click the blue check mark button or press the Enter key to complete the update.

When using "send tab to device", the submenu previously showed all synced devices, in my case, more than 10 devices. Recently it only shows 4 devices and there is no way to access the other ones. Is this broken or is it a recent change? If so, can I revert the behavior with a preference?

Under "manage devices", I still see all of my synced devices, they just don't show up in the "send to device" submenu.
