Firefox 技術支援討論區

Even though I have the settings correct in the browser ('Open previous tabs and windows' checked under Startup in the General settings section), Firefox suddenly stopped doing this. I went to help and have tried everything suggested (for example, in this article -> https://support.mozilla.org/en-US/questions/1365225) to no avail. I generally have to have at least a dozen tabs open at a time due to the nature of my work and it is time-consuming and frustrating to have to re-open the every time.

I have tried the 'restore previous session' under the History menu but that is not an option given. So that isn't working for me either. 'Recently closed tabs' is an option but is greyed out / doesn't work.

It is possible that this is a result of a recent update as Firefox has been almost daily been asking me to update. But I do not know how to go 'back' to last version if that is the case ... or how to turn off the annoying update messages.

So what is going on?

Thank you in advance.

I have physical limitations and need to use middle mouse button to scroll.

However, in Firefox, middle mouse button to scroll is interrupted whenever the mouse hovers over a hyperlink or linked object -- and, fun fact, there are A LOT of links on the Internet, so this equates to a very janky and sub-optimum experience, in my personal use-case.

How can I make it so that the middle mouse button functionality is not hijacked by mouse-over context? I've already tried/disabled middle-mouse-button-click-to-open-link-in-new-tab.

I used to be able to install an extension, and than see it automatically pin itself on my toolbar now I have to select the add ons and theme icon on toolbar and manually pin each extension I install one by one. I do not want to have to keep doing this. Will someone please tell me what is going on and how to revert this back to how it originally was?

WHY is it that every time I try to search for something in Firefox it takes me to Wikipedia? I cannot use Firefox any longer for searches without everything going to Wikipedia. I cannot find any way to escape that page or get rid of it. This started about a month ago. I'm fed up!

In Settings → Privacy & Security → History → Settings..., I have enabled the automatic clearing of "Site settings" when Firefox closes. However, the clearing of all site settings causes the clearing of all my HTTPS certificate error exceptions (Settings → Privacy & Security → Certificates → View Certificates... → Servers). Is there a way to make some exceptions for the clearing of site settings? I would like the site settings of a few websites to be preserved, while deleting the site settings of all other sites.

Hi,

I go to many websites whose languages I don't know. When I used to use chrome, I could just right-click to translate it to English.

Unfortunately, I cannot seem to find anything comparable here. Is there any add-ons or anything that I can get for it?

Also, I wanted to create an issue in so that firefox natively supports this. This is the only thing that has kept me from removing Chrome altogether.

Thanks!

When I download an image in Firefox and open it from the downloads folder it will always open in Pixelmator not Pixelmator Pro.

If I double click on an image file elsewhere they correctly open in Pro, but in Finder, the icons are for Pixelmator not Pixelmator Pro. This can be hidden if I turn on finder icon previews, but selecting Get Info always has the Pixelmator icon not the Pixelmator Pro one.

Im not sure if this is a macOS problem, a firefox issue or a Pixelmator bug but it seems to be related to the way the files are registered.

Things I have tried:

Changing file associations in firefox. Rebooting Changing the open-with properties in finder: Open all with Pixelmator Pro Reset the Local & User domains with lsregister lsregister -kill -r -domain local -domain user -domain system -v

Hi :)

I use Firefox on my Asus laptop running Windows 10. It's one of these laptops with both integrated and dedicated graphics (Intel plus Nvidia).

I often experience this issue when putting a video in full-screen (especially when viewing trailers on Steam, but this may just be because I mainly use my Windows laptop for gaming, and thus most of my video consumption here is from steam). This screen will briefly (for less than one second) turn black and audio will pause before the video appears in full-screen, and playback resumes normally.

It "feels" like a GPU switch is taking place, I'd assume from the integrated graphics to the GeForce card. This is not the proble. The issue appears when I return from full-screen mode. I always have several Command Prompts open with SSH connections to my Linux server and sometimes my MacBook Pro. These windows are now empty. That is, all text is gone, and I can no longer interact with the sessions. They're not "broken," as in they're not saying "Not responding" and don't ask to be forcefully closed, they're just black windows with borders around them. All I can do is close them all down and open new ones to reconnect and start over from where I think I remember I was.

I should note that this doesn't ONLY happen with Firefox videos going into full-screen, it has also happened after launching a game and returning to the desktop. This strengthens my belief that this has to do with GPU switching and/or video "mode" change(s).

Assuming I'm correct (my IQ is 5,000 and I do do the very big brians), is there any way to control how videos go into full-screen in Firefox? Or "lock it" to a specific GPU? I've rummaged through about:config and haven't seen anything that seems directly relevant.

I've already tried using the Windows settings to tell the system that Firefox.exe should use the integrated Intel graphics only, but this has no effect.

I remember I used to use "Media Player Classic" many years ago, and it had a slew of options of how to render full-screen video. IIRC, it had stuff like "Overlay," "Windowed," "Windowed borderless," "DirectX," etc. This make me wonder if there's multiple ways of chosing how to render video in full-screen, then maybe one could direct Firefox to use a different one than the default and my problem might disappear? Or maybe one could tell Windows that if an app wants to go into full-screen video mode, Windows should pick a specific mode for it?

I'm not a Windows developer, so I don't know :) But I'm hoping someone has a good tip, because I'm finding myself using this system more and more, and this is my biggest problem with it currently.

Thanks in advance :)

I have the plasma browser integration extension and the corresponding package for my distro. But it doesn't work and I get the "failed to connect to native host" message. Am I doing something wrong? I use: KDE neon 5.27 KDE plasma version: 5.27.3 Firefox edition 111.0, Mozilla Firefox for Ubuntu Thanks in advance!

I have Adblocker Ultimate as an add-on. But I can't seem to put it in my toolbar. I have searched the internet to resolve this problem and nothing worked. It is listed in my Add-ons manager but I can't get it to show up in any bookmarks or the toolbar. It does work but I can't find it anywhere.

Every time I use Google Meet, Firefox show me a tiny orange controller over al my desktops in Fedora Linux. It is a bit annoying an distracting. Maybe could be great this icons appear in the os panel in linux.

what the hell is wrong with firefox windows? /all my extensions are not showing in my toolbar. No themes are showing correctly. Just more problems to work around, as if I have the time, to go along with the "improvements" for my life?

Okay, Mozilla Firefox seems to be very safe. BUT then you took away so much that now I have to have extensions to do what I want. But every time I go to look at an extension, I see a warning that Firefox does not monitor it for safety or security. So basic - Firefox is no longer safe and I cannot have a good experience unless I take a risk? Why can't Firefox have its own extensions?? How can I determine that an extension is safe before it is too late?

I have a new laptop so needed to install an adblock. The search results page gave many choices. However, no matter which one I clicked on it said this page is not available in your region. Now how is that possible seeing as on my previous laptop and in the same region I could install the add on? I have had to use a VPN to install the adblocker. Please explain how regions prevent the installation and why it happens. Firefox is universal or so I thought.

I was totally blindsided by the changes imposed by the switch to this feature. Having now read up on it I can understand the need for it, but IMHO the implementation is... not optimal. Why do we have to have two "overflow" icons? Why could the two functions (traditional overflow list and new Extensions Management) not be maintained under a single button/function as before? (I don't care which symbol would be used, but splitting up the access to these functions? Come on!) AND why can we no longer order the items on the new overflow menu the way we want? --at least, I haven't found a way to move them around. Further, when extensions say that they "Can't read and change data on this site", does that mean that the extension is broken, nonfunctional, locked out, etc., or are we required to do something to restore it to functionality? -And if so, do we have to do this for every extension, on every site? Let me just say, not a huge fan at this point. Ugh.

At one time there was a userchrome patch which could be applied to obtain legacy-style square corners on the URL bar and the search bar. I can not get this to work despite trying several different suggestions and I suspect it may be related the the Proton redesign.

Can anyone suggest a userchrome mod to obtain the desired square corners?

Hello, I'm having an issue with my overflow menu. When opening the customization screen for the toolbar, I can't seem to drag certain toolbar elements into it? The buttons on the customize screen itself work correctly, and some of the elements present on the toolbar will change between visible and overflow just fine, but others I am completely blocked from moving. Please assist, as this is seriously impacting workflow.

Hello, I've been dealing with this issue for some time now, but I don't know when it started. One day pages started being displayed with Impact as my body copy, but I never changed anything about my fonts in Firefox. I thought it was something with my system fonts, but I've since uninstalled copies of Impact on my Windows 10 PC. I'm not sure where else to look, but Impact is a difficult font to read as it's super bold & condensed. Makes reading body copy, especially small type, hard to navigate.

Any help would be greatly appreciated!

Thank you in advance!
