Firefox 社群討論區

Every time I close and reopen the browser (and then check the Process Manager), all my pinned tabs are there and taking 20-30 megabytes each while I didn't click on them and they're supposed to be unloaded after startup

None of the unpinned tabs are in the Process Manager

How do i stop this?

-- Windows 11, latest browser updates

I found the tab groups more annoying than useful, so I went into about:studies and removed it, but doing so just makes a study entirely disappear with no way to bring it back if you misclicked, so that made me wonder, is removing studies permanent? Is it impossible to opt back in once you've opted out of a particular study?

I'm not particularly regretting my choice in this case, but it made me nervous how easy it would be to lose access to a feature just by accidentally clicking the wrong thing.

After my Windows 10 laptop being in sleep mode I found my background picture changed and all my Firefox tabs missing (while my bookmarks, add-ons, history etc. saved, and all other apps functioning properly). Recently Closed Windows menu was inactive and using Restore option in Library had no effect (despite availability of recent saves).

I found out that Mozilla folder was just missing in %appdata% (e.g. Profile Folder in about:support leaded to a non-existent directory). No manual changes to Firefox settings/data were made and no new profiles created.

What might be the problem and are there any ways to restore my tabs?

All of my tabs at the top of the Firefox window have vanished. There's a list of websites at the left side to choose -- but I am not able to open more than one window. I want to restore all of my tabs!

When I click on a link, it opens in a new tab. I do not want the link to open in a new tab but to open in the current tab, how can I change to this please? Thanks, Andrew.

I have vertical tabs enabled and I'm trying to access the tab overview menu to close duplicate tabs. Unfortunately I can't find this menu anymore. If I disable vertical tabs, I can see the icon in the top right. How do

How do I access the tab overview menu when using vertical tabs?

Thanks

I don't like the default homepage provided by Firefox, so I found an extension that can offer better tabs. But when I open Firefox, my homepage doesn't show the page provided by the extension. It's still Firefox's default homepage. Only when I open a new tab will the page provided by the extension appear. Also, the settings don't offer the option to replace Firefox's default homepage with the page provided by the extension. I need to replace the homepage from Firefox's default homepage to the tab provided by the extension.

In many cases when one opens a new tab, the new one is opened on the right of the "parent tab". After reading the web page of the new tab, one often decides that the new tab is no longer useful and deletes it. Firefox automatically opens the tab on the right of the deleted tab, rather than resuming the "parent tab" on the left. This seems to be an ineffective design as probabilistically there are perhaps >90% chance one wants to go back to the "parent tab".

Q1: should Firefox change the default for resuming the left? Q2: is there a setting that user can change?

When I click on a bookmark, FF opens it in the current tab, overwriting the site I had open. I have to add a tab, then click on the bookmark to have it in a new tab. This is an annoying extra step. How to I change it? I already tried the open links in new tabs instead of windows. Makes no difference On or Off

Is there a setting that prevents Firefox from closing immediately when the X in the upper right corner is clicked? Thinking a question "Are you sure that you want to close Firefox" should pop up. Recently I've closed Firefox accidentally and lost all of my open tabs (I don't keep history).

It seems firefox has changed the behavior of tabs. When I go to open a closed tab, I see a list of all the tabs that have been closed from every window. I want to restore the previous behavior where "recently closed tabs" only shows the tabs that were closed in the current window. I saw some about:config settings, but I'm not sure what they do and I don't want to end up losing the tab history all together.

Thanks

This code in mozilla.cfg used to overwrite new tab, but as of latest firefox 136.0b1 no longer works. Any way to fix this? There error in Browser Console.

// mozilla.cfg needs to start with a comment line var {classes:Cc,interfaces:Ci,utils:Cu} = Components;

/* set new tab page */ try {

 Cu.import("resource:///modules/AboutNewTab.jsm");
 var newTabURL = "file:///D:/Documents/images/home.html";
 AboutNewTab.newTabURL = newTabURL;

} catch(e){Cu.reportError(e);} // report errors in the Browser Console

Running Linux Mint 22 and FF 138.0.3. Normal practice is to leave 2 or 3 FF windows open on shutdown so the same windows and tabs will re-open on future boot-ups when opening FF. In the last several versions of FF as well as of the OS, those tabs appear on boot but display random text within a random tab for a given window. Also, the highlighted icon in the tray does not match the window that has opened. If I click and re-click the tray icons, they eventually display as expected.

Recently an update made it to where closing a tab group no longer works. It closes MOST of the tab group, leaving the last used one active along with a number to the right such as "+3" to show there are three more tabs hidden. This completely defeats the purpose of being able to close the tab group in the first place. In order to get around this, you have to click another tab to make it active and only then will the tab group you tried to close, actually close. Is there a way to disable this behavior so that closing tab groups actually works?

Assuming there is no fix, how can I downgrade to a previous version without losing all my settings, bookmarks, etc? Can I just uninstall the broken version and install the older version?

Thanks!

For some time, maybe 3 updates ago, when I open Firefox with my many tabs, I have this problem. The first 3 tabs that I close leave a blank space the width of 3 tabs on the tab bar. After that any new tab opens to the far right spot at the end of the blank area. This happens in a private window too (extensions closed). After I close a session, then reopen later, all my tabs are still in place but the first 3 that I closed reappear where they were at the start. Strange.

The only Firefox will open a link in a new tab is if I force it to do so by right clicking each link and choosing open in new tab. Before it automatically opened in a new tab.

This seems like a relatively new feature that I don't see a setting to toggle. How would I disable the drag-and-drop area at the top of the vertical tabs which prompts me to pin the tab?

With FF 140.0 on both WIn10 and WIn11, new tabs opened automatically then closed after less than a second. Initially I thought this was due to malware, but on inspecting the History, I found the source of this annoying behavior:

// SidebarUtil.tab.js

// This is just a placeholder file to be loaded in a temporary tab to check if a sidebar is open and how wide it is.

Is there a way to STOP this sidebar checking with its tab opening/closing without disabling Java entirely ? Is this annoying behavior really necessary in FF ?
