Firefox Support Forum

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.

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?

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.

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?

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 ?

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.

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

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?

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 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.

Had to disable Browser Guard because of problems with far too many websites that I access on a frequent basis (MS Edge works fine). Problems noted:

• Slow loading of many website page.
• Firefox often hangs up (cannot close webpage) when loading websites.
• Problem most severe when load a folder of websites at the same time.
• After Firefox hangs up and I try to open Firefox again, get error message that Firefox is still running.
• All sites with problems are configured in Firefox settings as "allowed" safe sites.
• Latest update didn't resolve the problem.
• Microsoft Edge works smoothly.
• Reimaged PC to Windows Image saved a month ago to see if older version of Firefox would work better--No improvement, problems noted above persist.
• After disabling Browser Guard, Firefox was able to quickly load the same sites I was having problems with, even when opening from a folder of multiple sites.

This problem is a recent development, what changed? -- Are Browser Guard updates different than Firefox browser updates?

I used to have ten websites in the drop down of my address bar. Through an update or something I did there are only five now. I can't find a setting for this anywhere. I want to remove a few and some others. How to do?

Hello, With the latest Firefox update I lost the LastPass add-on, and Firefox will not let me install in again. I get the message "LastPass: Free Password Manager could not be installed because Firefox cannot modify the needed file." Can you help me with this please?

Thank you, Colleen

When using Microsoft Outlook Online, I cannot right click and paste into the body of the email when using Firefox. The paste function does not even show up as an option. This use to work until I downloaded the most current version of windows 11. I can CTRL V and it will paste. It works on Edge and other browsers.

In browser settings i've disabled telemetry and data sharing with "mozilla". Why do put mozilla in quotes? Because the data is actually going to google. I'm monitoring my computers connections and i see firefox connecting to google immediately after opening the browser, that's without connecting to any website. Firefox used to be a great privacy browser, these times are long gone and it's a shame. Mozilla, you have lost all honor.

Plus, libraries of firefox are proprietary? Which part exactly? Forks of firefox are most likely affected by the sroprietary libraries aren't they...

when i tried to go to the website (addons.mozilla.org) it says: "

Secure Connection Failed

An error occurred during a connection to addons.mozilla.org. The server uses key pinning (HPKP) but no trusted certificate chain could be constructed that matches the pinset. Key pinning violations cannot be overridden.

Error code: MOZILLA_PKIX_ERROR_KEY_PINNING_FAILURE

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

i don't really understand what it means, but yeah its says that.

When will Mozilla introduce RTX Video Super Resolution technology to its Firefox browser?

Hi

In the attachment I've send you the bug, it's happening all the time. Most times while writing something down, or just casually using GitHub website. I want to report this bug 'cause it's a little bit annoying.
