Hello!

I can't figure out what setting to fix this: every time I click to open a new window, about 35 tabs automatically open up that I have closed several times in the past. I simply want one new window without any previously opened tabs.

I've tried:

• clearing my entire search history several times
• shutting down Firefox and reopening (which opens up all those tabs)
• uninstalling Firefox and reinstalling it
• initiating the latest Firefox updates
• restarting my computer
• turning my computer on and off
• looking through every single preference in my Firefox settings (I've unchecked anywhere it talks about opening tabs)
• reading various articles on Firefox's support page and on other support websites to try to figure this out (there's little info on this problem; the support is mostly about how to save previously opened tabs

Please help! I'm tired of having to close down all these tabs every single time I have to restart my computer or have to shut down Firefox. It slows down everything I'm trying to do.

Thank you!

My Dell Laptop INSPIRON 3793 running the Firefox/Mozilla Browser when I stream in Youtube or LiveNews periodically goes into the images in the photos I uploaded here. I am compelled to do a hard restart. I have been working with Dell Technical Services and they indicate they have no history of this issue. I am running Windows 10. My system has all technical updates including current drivers . I really do NOT want to move off FireFox but I getting pressure to run another Browser and wait and see if the problem surfaces. Is there any history of this issue with this Firefox. Any help or insight you can provide would be greatly appreciated. Thank you, Cate Brown

When I access bookmarks using the manager/editor I see all bookmarks. However when I try to use bookmarks from the dropdown in the toolbar, I only see some bookmarks. I think it's the newer bookmarks that are missing but not certain.

Ok. The update downloaded 2 1/2 days ago. I've used Firefox since that download. It didn't install until now. 2 1/2 days later. Why the long delay? And why don't you have something show up in the banner or toolbar that designates that an upload to Firefox is happening? Now, we all have to guess why Firefox is behaving slow and erratic, close and re-open, and check for version.

Yesterday there was a pop =up massage that looked like from Firefox. It suggested to accept an update that will get rid of an error when a site is not displayed. I accepted the update. Now the site that was generating an error is displayed 15 minutes later but doe not perform a simple search - it is producing a blank screen. Another website is now blocked. All articles that I found through Mozilla or other pages did not help to get to the source of the issue. Need some serious help from your tech support.

Thank you,

I am getting tired of being told replace this file with this

does it read firefox expert or intermediate on my account? no it does not it reads a person with no knowleage or skills in this field

and you are basically expecting them to figure this out on their own by giving the smallest shread of help by saying "replace the loginsjson with the logins-backupjson"

Yet i have no idea on how to do that.

so you basically caused a blind student who has no idea what there doing

because the F...ing instructors arent giving descriptive detail instruction on how to perform the task

and its actually sad i have to even do this

so for the last time please will someone give detail instruction on how to replace the loginsjson in the profile folder with the logins-backupjson that is on my desktop screen

and its not like i can just search this because iv tried and what do you know its given as much help as you have

I use firefox with duckduckgo as my search engine.Every search was becoming so slow so I went to settings and deleted cookies and site data thinking this would unclog things. Now I cant access any site. Is there a way to reinstate this data?

Hi, Hope you well. My previous laptop was stolen and I'm trying install now all my saved bookmarks. I had no problem to get them back on Chrom after looging to my Account. But I can't get back my old bookmarks on Mozilla. I see only the one which was saved on Chrome. Can you please help restore all my bookmarks before today day? I'll be really gratefull for help. Regards, Renata

Blank Page when clicking on tracking link from UPS website, https://www.ups.com/track?loc=en_US How do I fix this ? Thanks

Dear friends at mozilla.org,

Thank you for your excellent browser, which I've used almost from its first versions.

I'd like to compile its source code, which I've downloaded from your website, into a working browser. I've spent several days, and get only as far as not-terribly-helpful error messages, that indicate strongly that I'm using versions of tools and libraries that the source code doesn't like.

I'm using

 linux kernel 6.1.0-13-686-pae (from Debian)
 gcc 13.2.0-9
 perl 5.36.0
 python 3.11.7

It's sufficiently important for me to compile firefox that I'd install a fresh linux system for this purpose. Could you possibly recommend to me what linux distribution I could install, and versions of compilation tools, header files, libraries, etc. that are known to work for compiling firefox? I'd be glad to report back to you my results, to help others who'd like to compile firefox.

In case you're wondering, I'm perfectly competent in installing software, including compiling anything. I'm an M.I.T. graduate, and have been a professional computer programmer for most of the half-century of my working life.

Thank you kindly for any response that you have time to send to me.

Very truly yours,

Lyman Opie [email address]

I read this article on enabling/disabling hardware acceleration and I am missing the checkbox to toggle it. I am wondering if this is a firefox bug or if something about my hardware setup is unsupported. I'm using a 1080ti running on the most recent drivers, 546.33. Windows 10 Education version 22H2

since the update today my browser's been really slow to stream video across the board.

i fixed this a few months ago by turning hardware acceleration off and i tried to check if it had been turned back on and the entire option is completely gone from the performance section in settings.

i dont see an option anywhere else to change this, and i really dont want to switch back to chrome for streaming. is there a hidden option somewhere that im missing?

Hi,

I've been using the following in userChrome.css for many years

1. menu_close { display: -moz-box !important; }

to restore "Close Tab" in the File menu, based on cor-el's response regarding restoring menu_bookmarkAllTabs here:

https://support.mozilla.org/en-US/questions/799856

This stopped working some time ago and I am finally getting around to asking why.

I do have toolkit.legacyUserProfileCustomizations.stylesheets set to true, and other items in userChrome.css are working.

I am using 121.0 at home and 115.0 ESR at work and see the same (i.e. no "Close Tab"), in both cases on Debian testing. I do see this menu item when using the keyboard to open the File menu.

Any idea why this no longer works?

thank you, Greg

I was trying to troubleshoot a black screen of death issue with Windows10 that first started appearing after Firefox adopted the new Private Browsing icon. In the process of doing so, I tried every combination of Firefox settings imaginable. Nothing worked as far as Asus, Windows, or Firefox settings, rolling back/ updating various drivers, etc. So, I decided to refresh Firefox and when that did not work, I decided to uninstall and reinstall Firefox. I'm not sure if that worked as far as the original black screen of death issue is concerned because now Firefox no longer remembers my cookies and site data allowed exceptions (my only exceptions were my bank websites, which worked as expected until the uninstall/reinstall). I've tried selecting always use private browsing and always delete cookies and site data when Firefox is closed (my previous settings), but every time I close Firefox and return those three exceptions are missing. Any ideas would be most welcome. BTW, does anyone know how to use that folder Firefox puts on the home screen labeled "Old Firefox Data" because I was expecting there to be a .exe file to click on to reload all the previous settings in one fell swoop.

When i try to open youtube.com for example i used to only type in you or even you y for firefox to finish the whole URL for me, but sometime last month it dissapeared and never figuered out why after ALOT of trouble shooting to the point where I felt the need to create a new firefox account. Can you fix this for me? or just make everything deafult?
