Firefox 技術支援討論區

I maintain application that uses OWIN Microsoft library for authentication. It uses .AspNet.Cookies to pass auth information. For unknown reasons I see that Firefox 127 rejects that cookie. I've tried with SameSite Lax/None/Strict and Secure param but no results. Previous versions and other browsers ( Chrome, Edge Safari ) woks fine. Any idea ?

I restarted my Windows 11 laptop and got error message about user profile. Restarted again and looks like it was corrupted so deleted my my user profile and Firefox config and bookmarks are gone!

Still have all the files just a new user profile and the old one is gone?

Any help how to get Firefox bookmarks back would be much appreciated

Good day!

After the last firefox update, there was a change in the way screenshots are saved. Specifically, the file names are the same, only for some pages they create them uniquely as it was before. I am sending an example of a name (Screenshot 2024-06-17 a[...]) that is the same for different screenshots and therefore I always have to rename it. Before the update, this never happened, each screenshot had a unique file name, so it was saved without the need to enter a file name.

I use this feature very often and i find it very annoying to create file name and it is very impractical and time consuming. Can it be set somewhere? Or what should I do. I really like this function of firefox and I don't use another browser because of it. I don't even plan to, because I think it's the best browser and has a lot of great features. This is one of them and I'm really disappointed that it got worse with the update.

Hi!

I'm confused by the latest upgrade of Firefox (Version 127.0). It gave me the option to create a new profile or Exit when starting it. So eventually I went for creating a new profile and now my old one seems lost. This is not what I wanted.

When using my shortcut on the taskbar, which I've used for years, it suddenly complained I was using an old version of Firefox. This has not happened for me in decades. I've lived with the Firefox installation on this computer for a very long time and it has smoothly upgraded in the background until now. So what is going on now with this upgrade? Is it a major new version of Firefox that doesn't migrate a current profile?

Hello,

I was editing a fillable PDF document in Firefox, which I had saved repeatedly (saved over existing file) as I was making changes.

After a crash, I selected "recover session" and the document was open but was now empty. Another document I was editing, which was not open in Firefox but was being saved to a separate file, did not experience the loss of data entries.

Would anyone happen to know the reason for this issue and whether there is any way to recover the data?

Thank you.

Good morning from Holland.

I am amazed not being able to open sites like Banggood and a few others. Tried to delete all the controls on the item but it does not change the behavior of Firefox. Please inform.

I reinstalled Windows because my Windows got basically completely corrupted, I tried to log in to Firefox after reinstalling and it won't retrieve the bookmarks I had until 15 or 16 June, please help I can't get them back

Using Firefox on an ancient Dell with XP to run one IP security camera, It may have succumbed to a software glitch. The message now on startup, after an initial failed attempt to load operating system is: C0000218 Registry File Failure. Registry cannot load Hive File, log, or Alt (Corrupt, Absent, or Not Writable)

What do you suppose can be done to de-glithch the os loading routine, so I can keep it out of the landfill.

Thank you, Tony H

I have streamed TennisTV in the past no problem but now it stutters and task manager shows CPU 100%. It also shows Firefox running 2 processes which consume CPU and accounts for the 100%. So I closed one of the processes (the one using least memory) and it solved the problem. So how can I stop this second process from starting, it seems to consume CPU without actually doing anything?

Need to know why this problem of Firefox (on Linux) suddenly arose. When attempting to make audio or video calls it responds with, Does not work on Firefox browser. Yet it continues to work with about half my contacts.

Respected Sir/Mam I saved my password on Firefox but when i reset the password of my firefox account all my saved password are gone. How Do i recover all my Pass??

Hi,

I factory restarted my computer and reinstalled Firefox. When I signed into my Firefox account, all my bookmarks showed up but none of my tabs were loaded. I figured out how to load my tabs up from my previous session but all my bookmarks then deleted. I tried to re-sync but none of the tabs showed up. When I try to restore my bookmarks from the manage bookmarks library, it does not appear. I do not have a backup file for my bookmarks.

When I try to login to my Social Security account after pulling up the Soc Sec site (ssa.gov), I get this message:

"Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

I tried waiting a couple of days and attempting a login again. I also tried turning off my VPN, using a new tab, refreshing the site and restarting my laptop. I do not get this message when I use Safari to login, but I want to use Firefox.

Thanks for your help in fixing this problem.

Ive been using firefox for many years. The new update took away the bookmarks toolbar. My preferences are still "Always on". But, I can only access Bookmarks through a drop down menu. Just wanted you to know. Thanks

Sorry, not sure where to put it for the "topic".

Tried this link: https://support.mozilla.org/en-US/kb/recover-user-data-missing-after-firefox-update

I see TWO profiles listed.

As the current one isn't what I want I try the second one "launch in new browser" - as said in the notes.

All that does is throw me back to the "welcome to Firefox" page.

No, it isn't the end of the world, but I had a few open windows/tabs. (By comparison to this machine which has A LOT of windows and tabs open)

They were useful/used/needed stuff.

It is a DIFFERENT MACHINE to this one. I haven't logged in here from the OTHER machine - may in the future if required/asked.

I'll try to leave well enough alone for now, but I do need that machine and this is a huge bump in the usual smooth flow of things.

BTW - just mentioning. MANY sites showed/suggested how to restore previous sessions but they all point to the HISTORY menu and then show RESTORE OLD SESSIONS.

Doesn't exist on either of my machines.

No data shared as this is NOT the machine with the problem.

I am running a dual monitor setup. My primary monitor's resolution is 3440x1440, and my secondary is 3840x2160.

The text on my Firefox toolbars and menus looks very clear on my secondary monitor (3840x2160), it looks as I would expect it to; however, on my primary monitor (3440x1440) it's smaller which makes it pixelated meaning it's much less clear. I've been using Firefox for about an hour and I'm already bugged enough to post here.

Due to the different resolutions I need to keep the layout.css.devPixelsPerPx in about:config to the default -1.0 so the windows scale as per my Windows 11 settings.

Hello,

i am following instructions from here:

https://support.mozilla.org/en-US/kb/automatically-fill-your-address-web-forms#w_turn-address-autofill-on-or-off

but i don't see option to enable autofill on desktop. On mobile, autofill only shows USA ans Canada. Why Chrome allow me to use address autofill and Firefox not?

I'm on Firefox 127.0 (42448) ios and all my private tabs were closed on update and now whenever I make a private tab it disappears after the app is closed or refreshes. It's kind of behaving like the setting where private tabs are closed automatically but when I looked in the privacy settings of firefox ios it's not there anymore. Does anyone else have this issue? I know theres an existing problem with tabs for firefox but I don't think this is exactly the same because my normal tabs are totally fine.

I am extremely frustrated with Firefox and it’s printing. This has been going on for quite some time. You’ve been playing around with what was a good and functional printer interface to one that is now a pice of junk! I have been using Mozilla since it was Netscape 2.0

I am running firefox Ver 115.3.1 esr 64 bit on a Dell Desktop running Win 7. In the past I go to a print preview and see how the print out would look on the page. I could also control, my printer functions, like color or black and white, and the quality of the printout.

Today my wife (not real computer savy) started printing several PDF files for compilation into a book/user help package. After she had printed out several articles and well over 20 pages she mentioned to me that the printer wasn’t printing correctly. I asked her what she ment. She showed me. She was printing double sided (to conserve paper). After she went to the printer and looked at the printout they were all wrong. The front side was fine, but the back side was upside down. So when she would put them in a binder, should could the 1st page fine, then flip the page, and you’d have to turn the binder over to read the 2nd page, then turn the binder around again to read the 3rd page.

This isn’t my idea of double sided. It would be fine if I was using a flip chart but not in a binder. So now I’m sitting on over 20 pages of scrap, not to mention how much ink I wasted at about $50/Black cartridge.

I sit down and try to see what she’d done. So I bring up a document, and want to print ONLY page 1 & 2 doublesided so I limit my waste of paper and ink. Sure enough it prints the backside upside down. So I change from flipping long side to flipping short side and try again. Same problem, 2nd page is upside down. I also notice that there is NO print preview, and I can no longer have access to “Printing Preferences” which allow me to change from black & white to color and vise versa, set the quality of the printout. All I can control is Black & White vs. Color, what pages I want to print and portrait & landscape.

I go over to my other desktop running Win 11 and Firefox V 119.0 (64 bit) and try printing double sided. It gives me the same options as Ver 115.3.1 esr 64 bit, AND it gives me a preview screen. So I select double sided printing and it prints the 2nd page upside down. UNSAT!

I’m in this fix because sometime in the past I did an update and you had changed the printer interface. I don’t know when it was changed, maybe before COVID. But it sure hasn’t helped me. So far I’m out over 20 pages of paper, don’t know how much printer ink, and over 3 hours in trying to figure out what’s giong on, then trying to get help, and then having you web sit drop the page I was working on so I lost this posting. Then I got smart and did it in my word processor. All in all a really frustrating day!!

Hope someone has some ideas.

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.
