Firefox Community Forum

I am logged into my Mozilla account on four devices: Laptop Linux, Desktop Linux, Desktop Windows, Phone Android. However, when I try “Send tab to device” or list the devices in the account settings, the two Linux devices are not shown separately, so I can’t send a tab from Laptop Linux to Desktop Linux or vice versa. In fact, when I edit the Device name on either of the Linux device, that name will also be shown on the other device.

How is this possible? How can I disentangle the two devices?

Firefox on new laptop windows 11. (AMD Ryzen 7 5800HS with Radeon Graphics)

Firefox on new laptop windows 11. (AMD Ryzen 7 5800HS with Radeon Graphics)

Have noticed only when i use Firefox i get intermittent flickering on the screen. It does not effect browsing, though it has frozen on a couple of occasions. I don't know if that is connected or just something else.

I have tried two trouble shoot 'fixes' i found whilst looking for a solution and neither have worked.

1 - turning off recommended performance settings and hardware acceleration. 1b - turning hardware acceleration back on.

2 - checking in troubleshoot mode to see if it's an extension. Flickering happened in troubleshoot mode too.

For some reason, Firefox just stopped working yesterday. The only way I could get it to work again was to uninstall and reinstall (the refresh option did not work). However, now I've lost all my bookmarks, passwords and customization. I don't care about the customization and losing the bookmarks is an annoyance, but I'd REALLY like to get my passwords back. The installation created a folder of Old Firefox data, but when I open the folders that I think might be helpful, like bookmarkbackups, they are empty. Is there anywhere else I can look where these might have been saved? I did not have a Mozilla account so no profile until now which I just set up in order to access the forum. Thanks for any help you can provide.

Trying to download and print one of my tax documents. File type is PDF. Even in the print preview, the right margin is at least two inches, and it prints that way. I tried clicking "more" and adjusting the margin settings, but that doesn't help. I tried printing through Chrome and Edge and it prints fine. Any ideas how to get PDFs to print right on FF without having to switch over to another browser to print a document?

I have Startparge set as my default search engine. I used to type directly into the address bar (see first image).

Press Enter, and the Startpage results page for this search phrase would show up. Somehow, this has now changed. I press Enter, but the result is just the Startpage home page, with a blank search box (see second image). So I then have to type the same phrase in again in Startpage's own box. This just trips me up.

The crazy thing is that this only happens sometimes - but more often than not. I haven't seen it work right for weeks: I just did it now to make screenshots, and it worked wrong. I just did it again and it worked as expected: pressing Enter took me to Startpage's results.

Any clues how to change settings to fix this?

Hi how do I i prevent Firefox from going into efficiency mode. When Firefox goes into efficiency mode it be comes slow and unresponsive. if I manually uncheck efficiency mode in task manager Firefox becomes quicker and less laggy until a few seconds to minutes later it goes back into it. The performance of Firefox in efficiency mode makes it almost unusable and can take up to a minute for it to start working again.

This just started happening. I'll close Firefox and then open a new private window. If I minimize the private window, then open a new normal window, it restores my previous session/tabs. Very strange. "Restore previous session" option turned off. I even turned it on, closed/reopened, and back off to test. I am using the latest version of Firefox.

When I click on a pdf file, Firefox opens and displays the file, rather than handing it off to Acrobat, which is my preference. I'm running Firefox 122.0.1 and Windows 11 Firefox seems to ignore the settings in General, Applications. (See attached image)

    If I set to Always Ask, Firefox displays the file without asking.
    If I set to Save File, Firefox does not save the file.  It displays pdf instead.
    If I set to Windows Default Application, Firefox displays the file.  
         (Note: Acrobat is set in Windows as my default app for pdfs.  If I find a pdf with Windows Explorer and open it there, Acrobat is launched and it displays the file.  IOW I've confirmed that Acrobat is set as my default app for pdfs)
    If I set to Acrobat, Firefox displays the file.

I see nothing in Firefox Settings showing an Add-in for pdfs Any ideas?

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

For the past couple of months I have been getting the message www.bbc.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR when loading pages on www.bbc.com website. I have done a search on the internet and it seems this is a common problem with Firefox and does not affect othere browesers. I have done what was advice given online but it does not solve the problem. It is getting so bad I may have to start using one of the other browsers even though I prefare Firefox.

Today I tried using a Socks5 proxy that requires user and password. It seems that this is still unsupported as already concluded in https://support.mozilla.org/en-US/questions/1237174 and https://bugzilla.mozilla.org/show_bug.cgi?id=122752

Any news on this?

Kind regards,

aanno

PS: I _was_ able to use the very same proxy with curl with

curl --proxy-user user1:pass1 --socks5 "http://localhost:1080" https://www.google.de

When I ask for new tab, it opens next the currently open tab

When I ask for a duplicate tab, it opens a new tab 5, 10, 20 tabs away. Why can't duplicate tab open a new tab adjacent to the currently open tab? Makes sense, right?

I can't' find an option to adjust this

Thanks

Hello,

I'm using firefox 122.0, 64bits, on windows 10.

Since a few days (issues might be older, I have not used those site in a while) I canot watch netflix, I get the aparently infamous error code F7121-3078, which aparently means my browser is out of date, which it's not...

I also canot use musescore anymore, https://musescore.com/user/166080/scores/359836 for exemple, the page load halfway and then I get a firefox error that this page is slowling it down and ask me to close it. It's the same for every single music sheet, the rest of the website works fine.

I've tried to use troubleshoot mode for both website, and it's not working. I'm runing out of ideas so I've come here for help.

Thanks !

Firefox used to auto fill forms for me but lately it does not. On the rare occasion that it does (for one web site), it fills in one field at a time, not all at once like it used to. It does not fill in my address either.

I tried the usual troubleshooting without success. I went to settings, privacy & security, passwords, and made sure "fill usernames and passwords automatically" was checked. I went to the history section and made sure "remember form and search history" was checked. I went to the custom settings for history section and made sure that Firefox does not clear "form & search history" when it closes. For some reason,(I am in the US) I don't have a "forms and auto fill" section to scroll down too as some users suggest, nor do I have the "auto fill address" box to check or uncheck. Nor do I have a "saved addresses" button to check or uncheck or where I can supposedly add, edit, or delete an address.

I am running windows 11 and use Malewarebytes for my antivirus, although I can find no settings in the Malwarebytes suite that would impact Firefox's ability to auto fill forms. Any suggestions??

As the title says, after a certain update(I'm not sure which, probably within the last few months or so), firefox on my machine starts crashing randomly. Some crash reports:

I'm using Fedora 38 workstation, GNOME as the desktop environment, and Mutter as the wm.

I have a desktop and a laptop. Desktop crashed, so rebuilding.

Firefox on both, settings same on both. On Desktop - Last Pass will not appear. On laptop, same as it always has been.

Image below from my Desktop without the Last Pass icon there.

I've downloaded the LastPass Extension from Mozilla a couple times.

Help, please.

Very weird.

I have a content filter to filter out inappropriate material. Included in the filter are filters for adult content on wikipedia, youtube,and google podcasts. however, all those sites are fully allowed on Firefox, as opposed to on Safari and google chrome where the filter is working properly

I have to create a new question because when I try to reply to the answers I received the system comes up with an error page.

My version of Firefox is 120.0.1 and has been downloaded from the Mozilla website.

The problems occurs with all PDF file both local and from the internet.

The attachments are highlighted in blue in t he opened PDF file but cannot be opened. There is no way to click on the attachments.

Attached is a screen shot of one PDF file because I cannot attached the PDF file itself
