I got a new machine, and exported from a windows 10 machine running firefox and got a "bookmarks.html " file that was saved to my desktop. I then used a USB drive to put it on a new LINUX box with firefox running on it. something happened with the "other bookmarks" folder in my bookmarks list. It is empty and I cannot access it. PLUS there is ANOTHER "other bookmark" folder on the bottom of the list that I cannot access or select.

The "other bookmarks" on the bookmarks tab is empty (the one on the top of the list). I can't move a URL to it. There is also another "other bookmarks" on the bottom. which I cannot select and therefore cannot get rid of. And I have a link to some place that I also cannot select (and therefore cannot get rid of).

All the bookmarks in my folders and lists are ok and they work. I think the bookmarks list (which I cannot find in the linux file system) is corrupted. How can I find it, delete it, and then try to import my new "bookmarks.html" again ? Using Linux POP-os ver 22. Most recent release.

Using noVNC to access a wired LAN host on Linux using Firefox v111 uses ~5% CPU on an AMD 5600X. Upgrading to Firefox v112 causes CPU utilization in the exact same use case to jump to ~35% with spikes over 70%. Additionally the responsiveness drops dramatically, and is difficult to use. I've tried a completely new profile with the default settings, and the results are the same. I've reverted back to v111 for the moment.

How do I prevent Firefox from re-opening my last session upon reboot, for example after my laptop dies or I shutdown without closing browser windows? I never never ever want Firefox to restore pages at any time for any reason.

Background: I use firefox for work, and I keep 7 separate firefox windows open to the sites I use to do my job. Because it's a pain opening them every time, I created a shell script (I'm using linux mint 21.1 by the way) to do it. I just double click a desktop icon to launch my shell script and all of my windows open in the order I like them to be in.

Unfortunately, if my laptop battery dies or if I just am in a hurry and I log out without closing everything, then the next time I log in and launch my script, it opens my first firefox window, which then decides to open ALL 7 of the windows that were killed when my laptop shut down, and then my script opens the remaining 6 windows it is supposed to open, for a total of 14 browser windows now open, and I have to close half of them.

What I tried: I googled around and the only thing I could find was the browser.sessionstore.resume_session_once settting, which appears to have no effect whatsoever when I restart (my test was to set this flag to false, open 7 browser windows, restart my machine without closing the browser windows, and then launch my script and the result was 14 browsers open instead of 7).

Version: I'm using Mozilla Firefox for Linux Mint (mint-001 - 1.0) with a Firefox version number of 111.0.

I want to remove some sensitive info from a pdf before emailing it. So I removed some info from a pdf file by colouring white over the text then printing to pdf. When opening new pdf document with edge or chrome the info is removed however with firefox the info briefly appears before disappearing again. So somehow after whiting out the text and printing to a new pdf file the info is somehow still there??? I would have thought by printing to a new file the new pdf would not hold the text underneath and print "white" blank space... no data behind it, am I incorrect in assuming so?

Hi I use Firefox on 2 mac and 1 IoS device. The passwords or saved logins don't seem to sync across devices, even though they are all logged in via my account. Kindly advise.

Hi there!

Whenever I open Firefox, I receive a notification that suggests I reinstall the browser due to a configuration file error. However, I am still able to use the browser normally and my settings remain intact.

Is there anything I can do to address this notification without reinstalling Firefox? I would appreciate any guidance or suggestions you may have.

Thank you for your time, and I look forward to hearing back from you soon.

Best regards, sander

Need some help with Firefox crashing. System: Windows 8.1 64 Bit instilled on a Samsung SSD, 24 GB free space, 24 Gigs RAM, Firefox installed on conventional HDD (G:\) drive, 1.03 TB free space. This has been the standing configuration for many years, working with no problems.

Problems began with FF update 111.0. Any attempt to download files (.jpg or .pdf) would cause the “save” button to freeze, and after a seconds FF would crash. If an attempt was made to change a setting FF would again crash so quickly it was impossible to attempt any changes. Oddly enough, FF update 111.0.1 fixed the issue (or so I thought) and things returned to normal. I assumed whatever caused the problem had been fixed.

Unfortunately, every update beyond 111.0.1 reverts back to the same freezing and crashing behavior. I have attempted the following with all updates above 111.0.1 in an effort to correct the issue. So far nothing has worked. BTW, Brave and Chrome work just fine.

Cleared out all cache and cookies. Changed download folder Opening in safe (trouble shooting) mode Clean install(s) Disabled hardware acceleration. Putting the entire program on C:\ drive (apparently the newer FF installer does not allow custom installations any more). Checked and updated all drivers

Currently I have disabled automatic updates as none of them have the same freeze/crash issue. I am out of ideas and would certainly be glad to get any advice. At this point Brave is going to be my new default browser. Yes, I know 8.1 is no longer supported but I am not in a position to replace this PC at the moment.

I've installed a new version of Ubuntu Linux and - as recommended on this page's FAQs - backed up my firefox profile, than copied it into the profile folder on the new os. Now Firefox tells me "You've launched an older version of firefox" and forces me to create a new profile :( Also loading the old profile in "about:profiles" leads to the same result

How can i restore at least my passwords? (When i try to copy only 4.db and logins.json from the old to the new profile, i get the same result)

I can't find an "import old profile"-function anywhere...

On the landing page for youtube, I used to be able to right mouse click on a video thumbnail and select "open image in a new tab" from the context menu and see the thumbnail in a new tab window.

After recent updates, (now using 111.0.1 64bit , on windows 10 pro), this feature no longer exists. It's not a change on youtube because the thumbnail is still recognized as an image and can be opened in a new tab when I use Edge browser. It seems like Firefox no longer recognizes the thumbnail as an image.

Is there any setting I can change to get the feature of "open image in new tab" back into the context menu. or somehow get Firefox to recognize the thumbnail as an image ?

I have recently updates to Windows 10. In the past PDFs uploaded via Acrobat. Currently they are uploading vi Firefox viewer. I have been able to SELECT portions of the file then SAVE AS . This included save as type.

The PDF displays ok. BUT I cannot find a way to SELECT . The TEXT SELECTION TOOL is not working. Is it just me?

Should I change to ADOBE and if so how do I do that?

I can view the barnes and noble website but cannot log into my account. Upon entering my login and password, I receive the following error message:"An unexpected error has occurred. Please refresh your page and try again. If this problem persists, please contact customer support." I have contacted B&N support and been told the problem is not on their end and to use a different browser because the issue "must" be a Firefox issue.

Since the update a few days ago, Firefox is crashing and some sites such as Trust Pilot, do not work at all on Firefox. I know it is Firefox because it works fine with Chrome. Even Google Search does not work right.

What is the problem?

When watching youtube or even doing a little task with only one tab the cpu usage from a specific firefox process goes upto 90%. And I have did everything that was given in the following troubleshoot method "https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resources" but still the same result. I tried with troubleshoot mode on with disabling all extensions but the cpu usage was still high. I have also checked with firefox's own task manager tool but there wasn't a single process that was using full cpu. I'll be attaching all screenshots below.

I'm running a Tiny11 vm and I'm constantly crashing in firefox. I close all unnecessary tabs, yet seemingly at random firefox keeps crashing. Attached are some submitted crash reports. I'm mostly just browsing websites, and sometimes opening PDFs in firefox. The only other open programs I have are things like eM Client (email client), and file explorer.

With the Gmail App installed on windows, how to open an embedded link in an email (in the Gmail App) in Firefox browser instead of Chrome Browser? Currently, I do a left click, copy the link address and paste it in the Firefox Browser. By default, on clicking the link in the Gmail App, it opens in the Chrome Browser.

Hello, so i have a hp laptop running on windows 11. I have 2 different wifi sources here at my home, one of them is a DSL zyxel modem from century link & the other is a Verizon internet gateway that runs off of cell towers. I recently logged into both of them to configure some of the settings etc. and in the past when i only had the DSL wifi, i would log into it via file explorer>network>network interface and then select the router & would automatically be taken to the login page. For the verizon wifi, i had to go into the browser searchbar ,while being connected to that network, and enter the default IP address of 192.168.0.1 and it would take me to the login page. I first logged into the DSL network and then for the first time ever, into the verizon one, and now when i try to login to the DSL network via my traditional method & also by inputting its IP address into the searchbar (both routers have the same default address to access setup), it takes me to the verizon login page regardless if im connected to it or not. If i input the DSL modems IP address into Edge browser while connected to it, it takes me to the correct login page for that network which leads me to believe that somehow something is messed up with my firefox browser. Ive already tried going into the saved passwords and deleting the saved verizon login info. Any other ideas as to what it could be? Thanks, JD

So when i visit a website that relies on changing local files, sometimes its the correct thing and others its not. I assume since im on linux it might be installing though a snap and something else. Any help would be appreciated.

Hello,

I had to deactivate 2FA briefly, and then attempted to use a reactivate it again. I am able to scan a QR, but when I try to enter the OTP codes that show up, I receive the following message "Incorrect two-step authentication code". This has happened with Raivo and Authy (the previous 2FA app). What is causing this?

Extensions no longer shows on Customize Toolbar tab on the latest version 111.0. I had Dark Reader and SoundFixer on the toolbar before and I can no longer add them back.
