I had a number of tabs open today (~40). Because Firefox started to malfunction, I had to restart Firefox. It happened to me before and I knew that I can restore my previous session so I safely closed the tabs.

When I restarted it, I opened a tab and then I tried to open the Application Menu, but accidentally closed the window. Now, when I've re-opened Firefox and attempted to restore the previous session only that last tab appeared.

Is it possible to recover the pre-previous session? I use Ubuntu 18.04. Where is this information located? and how can I retrieve it?

Are tab groups like containers i.e. isolated from the others, so thay I can access sites logged into different accounts for instance or separate browsing experience/cookies ?

Right-clicking to close Firefox tab is broken!

How - just how- are you supposed to close tabs now?

You used to be able to right-click, then close the current tab or tabs to left and right, which was great, and I used it almost unconciously This useful functionality has disappeared. I am using Win 10 on a desktop PC - and I would really like to be able to close tabs when I have finished with them!

Why have you rendered Firefox almost unuseable!

One very frustrated Firefox user!

When I open a new tab, i would like the page to be in focus and not the urlbar. This is what i used to have in my mozilla.cfg: ``` // Auto focus new tab content try {

 Cu.import("resource://gre/modules/Services.jsm");
 Cu.import("resource:///modules/BrowserWindowTracker.jsm");

 Services.obs.addObserver((event) => {
   window = BrowserWindowTracker.getTopWindow();
   window.gBrowser.selectedBrowser.focus();
 }, "browser-open-newtab-start");

} catch(e) { Cu.reportError(e); } ``` This worked until the last update. What solutions are there?

Hello i've been having some problems on the latest software of yours i'm most of the time watching livestreams but from update v.100 of your software it became weird tab suspends after some in activity which is a problem for me

i found a solution through ABOUT:CONFIG and disabled these 3 for videos 1 - media.suspend-bkgnd-video.enabled 2 - media.resume-bkgnd-video-on-tabhover 3 - browser.tabs.unloadOnLowMemory

for videos and live streams it was good it didn't suspend but my problem now since update v.102 is that video plays but the CHAT stops and doesn't reload until i reopen firefox to the front of my programs

although it is runnning in the background and NOT MINIMIZED

even when the live stream has some lags and re-buffer it doesn't rebuffer or refresh the page to reconnect to the live stream until i force my firefox in front of my programs or games and again it was not minimized

if there is an option in the about:config to change this please tell me i'm already losing my mind as i missed one of my friends live stream because of that suspension

thank in advance

When I pressed the "+" symbol at the right side of my tabs with the left mouse button, a new tab opens at the most right place. So far, so easy.

When I pressed the same "+" symbol using the middle mouse button, the new tab opened right beside the active tab. Now, middle mouse button and left mouse button do the same thing.

Work around could be to open the context menu (right mouse button) of a tab, choose "new tab" an get a new tab right beside the tab chosen with the mouse pointer while pressing the right mouse button.

Did something recently change?

Hey there,

during work I often open two windows of Firefox to have more information visible on my two monitors. Unfortunately I sometimes forget that I have a second window open, so I close only my "main" window and loose all tabs.

Is there a way to force Firefox to ask to close a window and loosing multiple tabs for every window open?

Right now this only happens for the last open window.

PS: I just found out about the keyboard shortcut of restoring a window (CTRL+SHIFT+N) recently. I would prefer a setting in my case.

Thanks in advance Fred

I don't think "Tabs" is the right topic, but maybe it's the best of the choices since "Other" isn't an option.

I have an email with a link to a monthly newsletter, which should take me to February's issue. When I click on, or copy/paste, the link, I end up with the January issue. When I copy/paste in Chrome and Safari, I get the February issue. The newsletter people suggested clearing my cache/cookies in Firefox, but that didn't help. No matter how I try to navigate to the newsletter in Firefox, I get to January. I have tried everything I can think of, and still get the January issue in Firefox, while that same link gets me the February issue in Safari and Chrome.

I'm using Firefox 122.0.1, on a MacBook Pro (Sonoma 14.2.1).

I'd appreciate any ideas you might have!

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.

Hello All!

I have recently tried to use Firefox View button in order to quickly open pages that I have opened on my Android device, however I found that only some (random) portion of the tabs appear in the Firefox View under [tabs from other devices/my android device].

Is there any way I can change that behaviour? This is renedring the Firefox View kind of pointless, as I still have to open my phone to check whether there was maybe one more important page that I wanted to check out, that was not listed in the Firefox View on my PC. At that point, I could very well just see what were I at, on the android device, and just google stuff again. The mixed approch (some opened via Firefox View and some manually) is more time consuming than either of the approaches alone, so I would really appreciate help, as Firefox View seemed to be a time-saver - I believe I have something set erroneously somwhere. Thanks!

I am on firefox 125.0.3. 64-bit.

Past experience. With just a few tabs open there was a "+" button at the right hand end of the tab bar for a new tab. When the number of tabs got too many (in my case 18) the "+" button was JOINED by a ">" button to be able to see tabs off the right hand end of the toolbar, but still use the new tab button.

Post update to the current version of Firefox, at the point the ">" button appears it is REPLACING the "+" button.

I know there are workarounds, but my "rut" is to use the "+" to get a new tab.

Is there any way of getting it back?

Note: Please read my reply to the post, below, for an update.

I like to have new tabs open at the end of my tab stream so that each new tab opens in consecutive order. This is only inconvenient when I have a lot of tabs and need to scroll to the end for the latest. Because I was working with a lot of tabs today I toggled the following to "true" in about:config —

browser.tabs.insertAfterCurrent = true browser.tabs.insertRelatedAfterCurrent = true

The issue I'm having is that after toggling back to false, new tabs continue to open after the current tab, rather than at the end as before.

I'm not clear on the difference between related and unrelated, so I've experimented toggling one on, one off and neither or both but for some reason the behavior continues to default to opening new tabs after current in each case.

I have also tried restarting both Firefox and the computer, but this has not had any effect, either.

I have included a screen shot of the present settings and behavior.

I have two computers, one for personal use and one for business. Somehow the tabs between the two computers are being shared and I cannot disable it. Both browsers are signed into different Firefox accounts, Sync is turned off on both, and there are no connected devices. Yet despite that, when I go to one computer, it pops up a Firefox icon (see attached) in the taskbar that lets me open the tab open on the other computer. This is incredibly frustrating and Firefox should not automatically share this information, and should not make it so difficult to disable.

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

I'm using Firefox Developer Edition v136.0b5, and I'm looking for a way to remove “Turn on Vertical Tabs” from the contextual menu, because I'm so used to reopening a tab by clicking on what was then the last item in the list, that every time I end up with vertical tabs lol.

I'm running v138.0.1, but the ability to group tabs that was supposedly introduced in v137 is completely absent from my browser. I can neither drag tabs onto another to create a group, nor create groups by right clicking on a tab. What's up with that?

everytime I open firefox, it automatically switches tabs like these which require authentication to log in. even though their password is saved, I am still required to click in sign-in button.

Its really annoying that these kind of tabs get opened automatically, and then I have to switch back. Is there a way to disable this autoswitch or better, let the authentication happen automatically since the password is already stored ?

How do I put bar between tabs, or, each tab inside an individual box ? I have tried many codes from various forums, but since this update, FF seems to ignore ./chrome/userChrome.css completely.

Hi,

In my Firefox Developer install the new tab groups feature seems to now be working like one would expect, but my main Firefox install (Firefox desktop 138.0 (64-bit)) has some issues.

I can add tab groups, add tabs to groups, but left mouse clicking the colored tab header does NOT close the tab group, like it does in Developer browser. Mode of tab group clearly changes, as the tab is either dark or light colored after a mouse click.

I don't remember changing any other settings lately in about:config, except setting tabs.groups feature to true, and I don't have too many extensions installed, and I also tried disabling all the extensions, but that didn't help.

I was trying to change some settings on Firefox and I accidentally closed it and lost all of my tabs. I have the setting enabled to open tabs from last browsing session, but I was messing with the extension OneTab and I lost my open tabs.

Just to be clear, it wasn't the fault of OneTab, this is was my fault for closing Firefox too quickly when it was restoring my tabs and I didn't allow it to finish.

Anyway, in attempting to recover my tabs, I have restored from backup my "sessionrestore-backups" folder; this didn't work. I have also restored my entire Mozilla folder in my profile; this also didn't work.

I also tried following this article (https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup), but the sessionstore.jsonlz4 file doesn't exist. I did a search for this file in my profile and it doesn't exist anywhere.

Does anyone have any ideas that may help?

Thanks in advance!
