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?

I used to be able to move my tabs around in Firefox, but now they've become "fixed" in position when I open them. I verified in the Help Files that one can "Change the order of tabs To move a tab to a different position on the tab strip, just drag it there using your mouse", but now I can't seem to do that. What do I need to do to restore ability to move the tabs around? Using Windows 10, , and recently in the last week Firefox updated itself while the laptop was "sleep"ing to Firefox Version 102.0.1 (64-bit). Thank you. ~ SR

If you have multiple tabs open and you hit Ctrl-T to open a new one, it opens it at the end of the tabs, and the cursor focus moves to the URL bar so you can start typing in an address/search.

If you right-click on any of those tabs, it opens a new tab to the right of that tab, instead of at the end (which is what I want, as right-clicking on a specific one to open a new tab, to me, means you are linking those tabs in layout and want them together) BUT the cursor focus DOES NOT move to the URL bar.

This seems pretty counter-intuitive, and means that so many times I right-click, Open New Tab, and start typing a URL and then see that I have to stop typing, click in the URL bar, and start typing all over again.

Is there an about:config to force the focus to the URL bar, or is this a bug? If there's no setting for this, I would definitely consider this a bug because you have 2 different behaviors for New Tabs.

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?

I have tried searching all self help topics. I have tried all available settings options. I have upgraded to the latest version 104.0.2. However, nothing seems to fix my problem which is that Firefox will not restore my previously open tabs when I reopen it. This problem started a few weeks ago. I have selected [Open previous windows and tabs] I have selected [Firefox will remember History]

Can you please help

Thanks Fred

This is the first time, that an update lost all of my tabs. Is there a way to access previous sessions, other than the most recent one? I would like to access a session from last week, and see if I can get my tabs back. I'm very unhappy about this and I've not been able to restore my tabs. The current tabs are place holders, and they do the reflect what I had before the update.

Since one of the last updates the behaviour for the tab re-sizing got messed up.

When there are only a few tabs with full size, those as well as the additional plus icon is shown. But when there are more tabs and they are re-sized, then the right side gets cut off. First the new tab icon dissapears and then also the last tab get's cut off.

I attached a screenshot with three firefox browser windows showing the problem, as well as a forth one with only 3 tabs open, which are shown in full size including the new tab icon.

This is a new problem as the tab resizinng and the new tab icon used to work perfectly fine no matter how many tabs were opened.

I use the Feedbro-Addon, which creates an own tab. Its url is: moz-extension://285d678c-ecb3-4003-923d-835fc9d8e0bc/reader.html

If I use it as a normal tab (instead of a pinned tab) ... it survives a Firefox restart. But if I use it as a pinned tab (which I want) ... it disappears after a Firefox restart.

I suppose it has to do with it being an addon-page instead of a "normal" page.

Is there a way to make it stay permanently pinned?

I recently upgraded to Windows 11 and installed the newest Firefox 111.0. I'm familiar with about:config and all general settings in programs involved.

I used to have any link open in a new tab, but stay focused on the current one. DuckDuckGo search results opened new tabs but stayed on the search results page. I can no longer do that and can't figure out what changed or how to return it to this behavior.

Tabs, history, bookmarks, basicly anything and everything that was crucial are gone, seemingly after recent update. I had similar problem a couple of month ago and didn't find clear solution back then, but it all got sorted out maybe in couple of days (probably with next update or something?). Well who would've thought i would get screwed like that a second time.

So i can't tell for sure whats caused it or how it got fixed. What i manged to figure out both times this happend is that somehow i have 2 versions of Firefox Profiles judgin by the dates of the cursed updates. So i guess my stuff is still there but i can't acces it.

Also worth mentioning is that both times i've got screwed by updates, my FF shortcuts from Quick Acces pannel stoped working and i needed to drag'n'drop em all over again.

Im at totall loss here, i know the info i've provided is almost nonexistant but if anyone knows whats up i would be greatly apreciative if you could tell how do i fix this and prevent it from happening in the future.

I am using Firefox 114.0.2 address bar only, no search bar. I do not remember when it was happened, but today when I want to copy and paste page address I found out that address bar did not display the page address as previous version, just display the words I searched as a search bar (if the search bar is enabled, and typed in search bar then push enter, address bar will display address of search result page, and search bar will keep displaying the words in it). I attached my screenshot below. Using another tab and "switch to tab" feature by Firefox, I found out the page address. In my screenshot, I typed "test" and using Google to search (I also tried Bing, Wikipedia and more and all of them have the same problem with their owned link) and the page address should be "https://www.google.com/search?client=firefox-b-1-d&q=test" but even I paste this link into the address bar, it will only display "test" like the pic. I think it is a trim feature but I do not which preference I should edit in about:config. I have set "browser.urlbar.trimURLs" to false for displaying http and www, but it is not work this time.

I've been using multi-account containers for a long time. I've always used 'ctrl + shift + # of container' to open new tabs in a specific container. Recently, that feature has stopped working - but only for some containers? I can still open containers 1 and 2 using that shortcut, but my other containers just don't respond.

I've tried deleting the unresponsive containers and creating new ones, but that doesn't fix the problem. They work great otherwise - I can still open them with my mouse. Is there a fix for this?

An old question but seems like the about:config parameters have changed recently. the following don't exist anymore : toolkit.cosmeticAnimations.enabled ui.prefersReducedMotion

I've searched with other keywords but couldn't find the new one.

As Title,

Whenever I try to go full screen and hover to the top of the browser, It originally showed all my tabs, but recently it has not been doing that. When I hover over and over, the tabs maybe appear 10% of the time, but whenever I click somewhere else other than the Tab Bar, it disappears.

I think this bug happened ever since I enabled "Hide bookmark toolbar". I have since reverted it back, but the error is still the same. Weird, since my tabs disappear since it has nothing to do with bookmarks.

I don't know if it is because i closed firefox task end, or if it is a bug from update to v119 (when i reopened firefox, there was the updated tab). But now when i fly my pointer on "recently closed tab", instead of only having the 15 last closed tab of my current firefox windows, i have also the 15 of each opened firefox windows. means if i have 2 page it show 30 tabs, etc. the first 15 being the tab of the current windows (ex: FF windows 1) and the 15 next for the other opened one (FF windows 2), when i check "recently closed tab" on the other windows it is reversed (the 15 first tab are the windows 2 closed ones, and the 15 next from the windows 1). It is me, or a global bug (or new feature). If the second, how to return to the former option (means having only the tab closed from the current windows showing)

I can't understand why the Windows menu shows us all the open windows, in no order whatsoever. Not chronological or alphabetical, just random placements, making finding anything a dizzying & time consuming experience, as I have to look up and down each & every time. I don't know of any other browser that gives no option as to how to sort this lis.

Please see https://support.mozilla.org/en-US/questions/1311330 That solution does not work for me. Mac Pro with M1 chip running 12.4 Thanks!

I recently came across this [https://support.mozilla.org/en-US/que.../1276091|question] when searching for a solution to unintentional detaching of tabs. The responses included mention of an addon as well as a new setting added in version 74 that sounded like the perfect solution for me by retaining the ability to detach a tab to a new window if explicitly requested via context menu.

I configured allowTabDetach to "false" but today had a tab unintentionally move to a new window because I clicked on a tab too quickly while the mouse was in motion. I'm not sure if there was a regression in behavior for this setting or if perhaps it does not combine well with the Tree Style Tab extension.
