Firefox Support Forum

Since updating to 121.0.1, only the top edge of the tabs in my menu bar are visible (see image). I tried reinstalling, restarting, and switching to a different theme. Any thoughts on why this is or how to fix it? Thanks in advance!

I accidentally closed both of my Firefox windows with an "x" and the rebooted my computer. After the reboot there is nothing under "History"->"Recently closed windows" and "Recently closed tabs". Is there any way to get my windows back?

Hi, Moz://a Support Team

I hope you're doing well,

I'm encountering a problem accessing the Moz://a website due to a persistent pop-up error message. Could you please assist me in resolving this issue?

Any guidance or assistance you can provide would be greatly appreciated.

Thank you for your help.

Best regards, Karlie

Hi everyone,

My computer crashed while updating from Windows 10 to Windows 11. Unfortunately, I had someone look at it and he formatted my hard drive and only did a partial backup of files. I thought my Mozilla Firefox account was syncing, but it seems like it did not happen in a while. Does anyone know if there's any hope in recovering the lost tabs and bookmarks? Any help would be appreciated. Thanks,

Kenan

After updating to Windows 11, all my Firefox webpages backgrounds are colored black even after choosing a light theme which only changes bookmarks and toolbar to white. I want white background like my old Firefox ?

Hello, Firefox somehow crashed. Opening did not reinstall the tabs. This has happened couple of times in the past 10+ years and I was able to recall from History to reinstall the Tabs. Now I don't see that function in the Menu. Please help. I know there is a time limit to re-install them.

If I am on a web site and click a link to another page on the same website Firefox opens a new tab rather than displaying it in the existing tab. How do I get Firefox to NOT do this?

I recently downloaded Tree Style Tab. I still see the horizontal tab bar. I would like to hide it. However, I have tried just about every answer I could find on Mozilla, Google, Reddit, and any other websites that offered solutions. Nothing has worked since the last update. This includes the "type in about:config, toggle to true, open profile folder, create userChrome.css file, copy and paste xyz code, save, and restart Firefox" route.

Any help would be greatly appreciated!

Ok, I've resolved this in the past, several version of Firefox ago, under windows. Firefox crashes silently, open it again and no tabs are restored. Open firefox again and look in recently closed windows and the one with my tabs is not there, only little utility windows that are popped up when I log in at the coffee shop, so my recently closed windows are overwritten with windows with no tabs.

So I go to my profile sessionstore-backups folder and copy it to the desktop. I have 6 files, previous.jsonlz4, recovery.baklz4, and recovery.jsonlz4 at around 8 megs in size. I copied each to the folder one level up and renamed them sessionstore.jsonlz4, and each time restarted firefox. All that opens is a blank tabbed firefox window.

There was never an existing sessionstore.jsonlz4 file anywhere I could find, even with firefox closed, this file never appears anywhere I could find it. Searching files with Windows was also unsuccessful.

I feel like I have captured the files with my tabs, based on the date modified, several were from before the crash. Why can't I find a working tutorial on how to restore my tabs? Nothing I've found on the support site works though I follow the directions exactly.

Thanks

I have been using Simple Tab Groups (STG) for a long time now. I am curious if putting tabs into groups saves any resources, i.e. is only the open group using resources (CUP/RAM), or is STG purely organizational in that all the tabs still use the same amount of resources as if they weren't grouped? If it is the latter, do you know of an add-on that would save resources? Thanks

I did a 'refresh' of my browser, thinking that basic user information would be saved. But I lost all my tabs in OneTab (extension). Is it possible to recover them?

How can I import or to which folder do I import bookmarks so they show up in the shortcut rows in a new tab? I'm trying to get away from Opera but I love the shortcuts displayed on a new tab. I tried copying all the appropriate bookmarks to the bookmarks menu folder and why they are in the folder they dont display in the shortcuts.

The imagine shows where I want to import to.

I have just started using Firefox and ticked that every internet tab is Firefox but every time I click new tab, it states "search with google or enter address" I cannot get into about:config to then get to browser.newtabpage.pinned How do I get rid of this Google message?

Often times when I open a new tab, I get a dot that goes back and forth and will not open the tab. This seems to happen if I don't use Firefox for a few minutes. It's like its trying to open but can't.

I am hopeful you will be able to help me. All open tabs NOW disappear after power failure or Comcast temporarily loses service or I restart my computer. This never happened to me before ~ if my computer was affected by outage or I manually restarted it a message came up to click on asking if I wanted my tabs restored. 1 click and they were restored ~ that option is not available to me now. It's frustrating and time consuming for me to "look" for, and "try" to find those tabs I had open. If someone does respond to my question I won't know its been done unless I receive an email because I'm not certain I can find my way back to this support page, primarily because I cannot remember HOW I even found this page in the first place! I bookmarked this page so perhaps I will be able to return to it. Thanks for the "How to restore tabs" help I HOPE you can give me. Marilyn West
