Firefox Community Forum

i have recently acquired a new PC and want to transfer all my Firefox settings to the new PC and have two questions:- (1) What file and what location do I post the file for Homepage shortcuts which involves 4 rows x 8 = 32 shortcuts that I want to transfer to the new PC without having to do it manually. Apparently Sync wont do it for some reason that I fail to comprehend. By searching this site I have found answers that say the file "prefs.js" hold these values. However, I have copied that file from my old PC onto the new PC but no result? Where should the file be copied from and to (full path from and to)? i have used "about:profiles" but then there are paths to "default" and "root". (2) I have exported the the Bookmarks from my old PC to the new PC but in one particular case the bookmarks are not the same. In this case I have a particularly large bookmark that contains three (3) Sub-Folders plus many individual bookmarks. When importing the file it does not include all the sub-folders - only two. This baffles me because if is exported with three sub-folders I don't understand how the imported Bookmark file can be different. Any advice would be most appreciated.

Hello,

i have precisely explained issue here with different screens. i would like to have your feedback

https://stackoverflow.com/questions/78995057/firefox-ocsp-fails-at-loading-private-https-website

I have just run the latest update to 130.01.

For some reason the update has errored FF and when I try and launch I get the the below error messages.

FF cannot load, not even in Safe Mode, so I am a bit stuck.

Does anyone have a solution to this please?

Thank you in advance.

Many of Linux Distributions take firefox binaries from https://packages.mozilla.org/apt/ as given in the Mozilla Knowlege Base Article Install Firefox on Linux. In this article there is a option to Install Firefox .deb package for Debian-based distributions.

However the binaries and libraries that are hosted in Firefox repositories are not compiled with the PIE/PIC flag. That prevents Firefox browser from using ASLR capabilities and to a large degree prevent Buffer overflows attacks. Please refer to the output given below for more details.

$ file -e elf /opt/firefox/firefox /opt/firefox/firefox: ELF 64-bit LSB executable, x86-64, version 1 (SYSV) $ $ readelf -h /opt/firefox/firefox ELF Header:

 Magic:   7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00 
 Class:                             ELF64
 Data:                              2's complement, little endian
 Version:                           1 (current)
 OS/ABI:                            UNIX - System V
 ABI Version:                       0
 Type:                              EXEC (Executable file)
 Machine:                           Advanced Micro Devices X86-64
 Version:                           0x1

The output of the first command is ELF 64-bit LSB executable, which indicates that it is not a PIE executable. If it had been a PIE executable then it would have been ELF 64-bit LSB pie executable. Similarly the output of the second command has a Key, Type, whose value is EXEC (Executable file). However for a PIE binary the value would be DYN (Position-Independent Executable file).

Can Mozilla please compile the binaries and shared libraries with the PIE/PIC flag and then host them in its repositories? Many of Linux Distros do not have the bandwidth to take the source and compile binaries for different architects and are dependent on Mozilla to provide the same. Doing so would be appreciated and would help in enhancing safety of Linux users who use Firefox as their primary browser.

PIE = Position Independent Executable PIC = Position Independent Code ASLR = Address Space Layout Randomisation. PIC and PIE are used interchangeably and imply the same thing.

It seems that in incognito mode when I go to youtube I am stuck at the consent page and it doesn't matter if I refuse all or accept all it will refresh and show the consent page again. If I go to youtube without incognito mode it works just fine.

Using Firefox 115.15.0esr (64-bits) on MacOS 14.3 (23D56) I'm not able to connect to https://mijnzakelijk.ing.nl/ while https://ing.nl/ connects just fine. These domains use different TLS versions, which may be related to the issue. The browser reports a failure to connect, and NS_ERROR_NET_INTERRUPT when viewing the networking tab. Tcpdump indicates the remote side disconnects by sending FIN on the tcp layer. I tried various config features to enable low TLS versions but that did not make a difference.

openssl s_client has no issue connecting, nor does Chrome, on the same system. For completeness here is the openssl transcript:

I would like to keep using Firefox for all my browsing, so I'm wondering what I can do to fix this. In about:config I have all settings containing "tls" to their defaults. I've tried enabling security.tls.version.enable-deprecated and lowering security.tls.version.min, but nothing seems to help.

I know from experience that contacting ING about such issues doesn't get you anywhere, and given the fact that another major browser has no issue I suspect it is best solved (or worked around) on the side of Firefox.

Why I cannot disabling this any fucking of firefox shortcuts it's a fucking shit opening stupid fonction every time I'm hit fucking ctr function open new tab or closing actual tab or open html code on actual webpage, why it's always fucking programmer decide what opening function without freely disabling this fucking stupid function? I want to work with a mouse not wit fucking keyboard. When will be able to work freely with firefox et stop to add and add and add more function?

In my Settings within Firefox,I have Clicked CLEAR ALL INTERNET CACHE on exiting Firfox BUT when I open CCleaner & Run it,It shows that no internet Cache is cleared after exiting Firefox WHY WHY

I tried logging in as as admin for a page on facebook, I have done this before.

It froze for a while then this page came up with this message.

"Sorry, something went wrong. We're working on getting this fixed as soon as we can."

I saw at least 2 FAQs with the same issue so I have deleted my cookies and tried a private tab.

Everything works fine with Chrome and Microsoft.

My dns doesn't resolve on Firefox and gives error Address not found. Originally I tried it on nightly and thought it's an Android issue but it doesn't work on desktop too. However,it still resolves on chrome.

I've set network.trr.mode to 3 and changed network.trr.uri accordingly.

Auto fill for credit cards has not worked for several months now. The option is checked in the privacy and security tab. When try to pay a list of my cards comes up but when I select one if doesn't auto fill. How can I fix that?

In chrome, typing "wow" in the adress-bar automatically suggests wowhead.com/cata (yes.. I'm a wow gamer, sue me) and goes to that page as soon as I hit enter.. firefox doesn't/can't. Same goes for all other "most visited" pages to various sites.

Another example (still using the wowhead site as an example) I start typing "assa" and chrome immediatedly suggest "https://www.wowhead.com/cata/guide/classes/rogue/assassination/dps-bis-gear-pve" and will go to that page as soon as I hit enter, again, firefox can't/won't. Sure.. I can hit "tab", but that's an added key-press I really don't feel is nesseceary.

Is there a way to "fix" this?

Greetings,

After having been "On th' Net", for approx. 6 hours earlier today, with No Issues,......About an hour ago, (And No,.... I didn't recieve a Firefox Update today, to the best of my knowledge, although today has been very chaotic & stressful),....I tried to open a PDF, of which I view on the Firefox Browser, & I got a "Couldn't load XPCOM."

I then "Right Clicked" the Firefox icon & tried to open Firefox as an Administrator, & I got the same message.

I then "Right Clicked" the Firefox icon, & sought the "Refresh Button", But there is none.

The "Installed Browser" for Windows 10, is how I've managed to get to this Forum, of which I do not trust.

My Email is via YAHOO/Frontier, & since I, for the moment, cannot access My email, of which, I'm thinking that to see any replies to this situation that I'm in, that I will have to use YAHOO, so as to access Frontier.

I've seen where situations like this have been occurring, & the most recent that I saw is this:

cor-el Moderator Top 10 Contributor 1/12/23, 1:08 AM more options An error message about XPCOM missing or about platform version usually happens because of a failed Firefox update that left you with a mixture of old and updated files in the Firefox program folder. This can happen in case security software was keeping a handle of some of the files in the Firefox program folder preventing Firefox from replacing all the files. You need to do a clean reinstall and remove the Firefox program folder to ensure that all files are replaced. You may have to disable security software temporarily in case the problem persists.

You can find the full installer of the current Firefox release (108.0.2) in all languages and all operating systems here:

https://www.mozilla.org/en-US/firefox/all/#product-desktop-release https://www.mozilla.org/en-US/firefox/108.0.2/releasenotes/

Will I be able to save All of My Favorites? I have several years of Favorites there & many of them are critically needed. I realize that the Add Ons/Themes/Settings will have to be re-installed/adjusted, but I'm good with that.

Again,... Keeping My Favorites is critical, & "If" they would be deleted, then is there any Possibility of Tech/Engineering accessing My Firefox Folder & saving them?

Regards

Hi there-

On my current Dell laptop (Windows 11) I have had a recurring issue with Firefox wherein any time two sounds play at the same time (say, a Youtube video is playing in the background and I have a sound play in a browser game) it makes one of the audio channels cut out for about a second. This issue only happens with Firefox, and I previously fixed this by changing the bitrate in my audio output settings. However, after an update, this issue has returned, and the bitrate settings I was using that were able to fix this issue now doesn't allow me to play audio on Firefox at all. So now I have no way to avoid the strange bug that causes audio to cut out.

I would love some advice- is this on Firefox's end, or my computer's? Is there a driver I could install or something to avoid this bug? What causes it?

Cheers, Noa

I noticed after a forced Microsoft Windows 10 update, AND whilst using CC Cleaner to clean out the cache, I was no longer prompted to close Firefox. I never opened Microsoft Edge and was not asked to close it to complete the CC Cleaner process. I don't want Mircosoft Edge and I especially don't like the feeling that Firefox must use Edge to operate. What can I do to clear this up.

After taking the latest update to Mac OS 15.0 - Sequoia I am not able to pull up any resources on my home network. I'm not sure if it was just added in this latest version, but there appears to be a privacy setting under Settings > Privacy and Security > Local Network that is likely the culprit I've discovered after testing another browser (MS Edge) that was having the same issue. The only issue for me is Firefox doesn't show as an app on that list for me to enable the setting so I can work with my local resources. Hoping someone can help.
