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).

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?

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.

I don't need to pin tabs, ever. Every time I try and drag a tab to the first slot, it always pins the tab, and I don't want it to do that. Is there a way to disable this stupid feature?

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 ?

Добрый день. В процессе использования браузера, вкладки самовольно перезагружаются. Играю в браузерную игру и ни с того ни с сего вкладка сама по себе перезагружается, выкидывая меня из игры. Это происходит по непонятным причинам. В настройках я отключил автообновление вкладок (about:config - accessibility.blockautorefresh: - true). Там стояло значение false. Но вкладки все равно обновляются без моего участия. Это происходит на всех моих профилях в Фаерфокс. Как это остановить? Это мешает мне пользоваться браузером и комфортно играть.

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!

This has been infuriating me for a few weeks now, I accidentally close tabs all the time when using Firefox and I normally right click the top and click the "Reopen closed tab option. However since this change, I have constantly been miss clicking on the "Turn On Vertical Tabs" options which is incredibly infuriating because It adds 3 more clicks to just reopening a tab. This "Feature" cannot be turned off no matter how hard I try and I am very close to switching to another browser due to this.

Mozilla tab keeps crashing (especially at YouTube) I was wondering if someone can help me find out why!

like tell me how to show the log or something to identify what is doing the crash.

Thank you in advance!

I'm on the latest FF 140.0.1 on Linux and I adore tab groups, I'm using it more and more to organize my browser windows. I am using the default (horizontal) tab group layout. Because I have a lot of tabs in the window, I collapse each existing tab group and sort tabs between tab groups.

I can move a tab into an expanded tab group with drag and drop. But I tried dragging and dropping a tab onto a collapsed tab group, even holding it over the collapsed tab group to see if that would work. Nothing seems to register, is it possible?

I would like to move a tab by drag and drop without expanding the collapsed tab group and move the window focus to the next tab. This would save time when I am organizing tabs!

The alternative is to Add a tab to a collapsed tab group, which also expands it and consumes horizontal real estate, forcing me to scroll (further) to return where I was organizing tabs. So I collapse the newly expanded tab group, scroll back to the next tab I want to organize into a different tab group, and repeat but this causes a lot of scrolling navigation to my workflow. It makes complete sense and I really like using menu navigation to add tabs to a specific group because it is discreet and I wish I could move tabs with the same method.

I searched Settings > Tabs and then about:config for browser.tabs.groups.* (and then every preference with tab in it) and couldn't find anything that made sense to me.

Thank you for any help!

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?

I tried to add maps.coogle.com to a specific container. this ends opening maps forparts of a second in this container displaying the cookie content page. regardles if a agree or not, it opens the cookie consent page in a new tab (looping forever) is there a way to add a site to a specific container using a config file? is here a way to add a site to a container, without having the subsites after the TLD, in the URL

Kind regards

After updating to Floorp 11.17.3 (based on Firefox ESR 128), all my pinned tabs now scroll with normal tabs. So, if I have enough tabs open that I need to scroll to see them all, my pinned tabs scroll to the left and go out of sight. Before update they were always in place, and only unpinned tabs were scrolling. Is there a way to make them stationary again?

In Firefox Nightly, I am using vertical tabs - Whenever I close a pinned tab and reopen it, there is an annoying divider I have to manually increase in size. This is super annoying, is there a way to do that automatically or remove the divider? Thanks!

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

The article at https://support.mozilla.org/en-US/kb/tab-groups says (and shows a mockup animation) to drag a tab onto another tab to create a tab group. It also says the feature is being rolled out in v137 and will be available to all users by May 6.

It's May 8, and I'm using v138, but dragging a tab onto another tab just reorders the tabs.

What's the deal?

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?
