Firefox Support Forum

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?

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

Okay so I just installed firefox to a new desktop and it synced up my extensions, passwords and bookmarks (minus bookmark icons/favicons which was solved simply by clicking on the bookmark in the toolbar and then firefox did the rest, kind of annoying but no problem)

Otherwise it seems all my browser settings, including settings I have done in the about:config have not been restored. I was under the impression that syncing firefox will sync browser settings and about:config settings but apparently thats not the case?

Is their a way to do that? I am less concerned about firefox settings as I can just screenshot a few pages no problems but I made many changes in the about:config that I am not sure I remember what I changed and theirs a million settings to change there so its not possible to recover that unless their is a recovery tool in firefox.

Again sync does not help here I need something more "robust" if that makes sense.

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,

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

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.

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

It turns out the copied logins-backupjson file i had pasted on my desktop screen was already overwritten by an added or removed login, thus writing over when it did have the saved login removed that i was trying to recover

is there any other way to recover the removed login?

i saw this response by Cor-el for another user with a similar situation

If you still have the signons.sqlite that was used in a previous Firefox version then you can try to restore passwords saved in that file.

Firefox 32 and later builds store the passwords in the logins.json file in the profile folder and no longer use the signons.sqlite file that has been used before (the matching key3.db file is still needed). If you still have the signons.sqlite file used in previous Firefox versions then you can try to force Firefox to migrate the passwords saved in that file (you will lose passwords saved in Firefox 32+ versions). You can force Firefox to reimport the passwords from the signons.sqlite file and rebuild the logins.json file with these steps:

   reset the signon.importedFromSqlite pref on the about:config page to the default value via the right-click context menu
   delete the logins.json file in the Firefox profile folder with Firefox closed 

When you restart Firefox then you should have the signon.importedFromSqlite pref with the value set to true and you should have the passwords imported in the Password Manager unless there may have been errors.

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.

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

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,

Ludmilla

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.
