Firefox Community Forum

After upgrading one machine from Fx 110.0.1 to Fx 112.0.1 (as per usual with "major" upgrades with the full install file) I noticed very high CPU usage when closing Fx, and it took quite some time to settle. I upgraded it to 112.0.2 via Help-About, but saw the same issue.

That is, starting Fx, opening a "private browsing window" and visit some site, say a search engine, then closing the private window and finally the first Fx window. (At the time I also see some spikes in CPU usage from the firewall software etc.)

Since I can’t have it like this, computer almost stalling for 30 sec, after closing Fx, and to see if there would be any update later to solve this issue, I uninstalled Fx 112.0.2 (I have complete backups of Fx profiles), and, just as a test, reinstalled Fx using the prior version of setup that I had, Fx 110.0.

Of course this meant a clean profile, not what any user wants to see (missing bookmarks is almost minor compared to all settings, incl. in add-ons, gathered over time. So I used the profile manager to change to my previously used default profile. After a restart I was greeted with a prompt that this couldn’t be done (since it may corrupt bookmarks(?) etc.) and I was left with the only options to abort (cancel) or create a new profile. Oh, great. I had not even used the newer ver. (Fx 112) to change or create anything, but I assume Mozilla could have something between the different versions.

So, I uninstalled Fx 110.0 (and of course in the process of creating a new profile/resetting settings it had reverted to "download updates in background", and I had to change that setting back, and stopped what was pending, during my tests trying to move it to my old profile). I installed Fx again, using the setup file for 112.0.1 and did a direct upgrade to 112.0.2, and pointed it to my old default profile, which had been used with 110.0.1 and during the first upgrade to 112.0.1.

Fx is working with my profile again, but it takes a very long time to close and (perhaps together with other software) consumes a lot of CPU, almost stalling the PC. During one such situation this morning I got two prompts for XULRunner "Could not determine any profile running in background task mode!" Never seen before. (I noticed that there now is a new folder in Roaming\Mozilla\Firefox\ called "Background Tasks Profiles".

Any help would be very much appreciated.

Hi. When opening the Microsoft Website (answers.microsoft.com) i experience some memory leaks. See photo for details.

Someone knows why?

Hi,

For years I have read directions to get my tabs back where is most logical for me, below the Bookmarks Toolbar. Now with this latest version of Firefox the workarounds I had before are not working.

To cut a long story short: I have made a Chrome folder under the Profile folder I have made CSS sheet with what looks like the commands I need. I have configured Firefox to read the userChrome.css sheet.

I have followed all the directions on this thread https://support.mozilla.org/en-US/questions/1375646 (most of which are repeated elsewhere) and it still doesn't work.

I am beyond frustrated - if anyone happens to know where I can go to request this as blinkin' option I would love to know.

Please could someone help me sort this out in the meantime though?

This is what is in the CSS sheet (which is in the correct place according to the above instructions - checked that already):

Thank you in advance.

Win 10 FF 112.0.2 (just about to update again). 2 Tb HDD x 2 I recently installed a new Sata drive after a previous one showed it was failing. I then had to copy over the partitions slowly over a number of days which meant a lot of disk swapping and partition label changes. I do have rather a lot of partitions between the 2 drives.

Anyway - my FF is on the drive not affected but which did have to be removed in order for the failing drive & the replacement to be mounted to faciliate the data swap. The upshot of which ultimately appears to have been that all my bookmarks no longer have the correct icon unless I visit the site although even then some stubbornly won't update.

Obviously not a major problem but it would be nice to have a quicker fix than wasting half a day visiting each site separately given there must be a few thousand of them :(

Whenever I right-click a YouTube video on the home page and select 'open link in new tab' followed by launching the tab in focus, the YouTube video on the corresponding tab automatically starts playing. How do I get the YouTube video on new tabs to stop automatically playing as soon as I enter the tab?

Troubleshooting steps attempted:

Disabling all add-ons. Selected block audio and video 'for the autoplay setting under Privacy & Securty. Set media.autoplay.enabled.user-gestures-needed via about:config to true

The strange part is that if I open Firefox in a clean, new profile, navigate to the YouTube website, and then right-click a YouTube video to 'open link in new tab' and then open the tab itself, the video DOES NOT automatically start playing. How do I get that same functionality on my default, main profile?

EDIT - Solved! For anybody who wants to disable autoplay follow this tutorial - https://www.youtube.com/watch?v=Xn7_PiwhG4M

Is it possible to change the displayed folder in the Bookmark Toolbar? So that not the folder "Bookmarks Toolbar" is used, but a self-selected?

Benefit:

For example, a Firefox sync account is used across multiple devices. But the most important pages differ from device to device (e.g. work/private). Accordingly, a different folder should be displayed in the Bookmarks Toolbar on different devices.

Why i am getting this error despite this website is operational through CHROME

I've been trying to copy an email address someone emailed me. (I use Microsoft Outlook.)

However, when I try to select the email address, Outlook seems to know I've selected it and performs some action, taking me to a different page. VERY ANNOYING!

Sites shouldn't be able to know when you're selecting text - that has nothing to do with them! How do I disable this?

I have a windows 10 desktop. I use several different browsers including Firefox. When online and searching for a site, I choose only https//: sites. However, I am getting an unsecure warning when I click on them. It opens the sites in private mode so why do they not open in regular search mode? Also sometimes when I am in a https//: site I trust & have been to before, the links receive an unsecure warning too. How do I fix this?

I want to make a suggestion: This last week I was financially hacked and I have to close all my bank accounts, etc. My biggest concern is anyone with my FF login info can get all my passwords, etc, if they compromise my phone or any device with my browser, and reach into EVERY financial institution I am affiliated with, not just my bank.

My suggested solution: Since all my accounts contain all my info in Firefox, let me choose one that I can control with biometric login only so I can block all my info unless my hands have been cutoff. You can add a back door with multiple info requests to the print, or request additional fingers, if I click add this. I am terrified they will get to ALL my empty credit cards since they hacked all my info. Personally I love the fingerprint, and if I lock it, it can ONLY be unlocked with my fingerprint, or additional things I choose. I don't have all my pwds handy, nor could I ever have what all I need. I am CONSTANTLY locked out because I don't recall my pw.

Hi, I have firefox on my Ubuntu 23.04. When i start it it shows a black screen. I click quit on my system and then i startup and it lunches normally. What am I doing wrong or how to fix it?

I am using the latest version of Firefox on the latest version of Mac OS Ventura, 13.3.1 (a). I wanted to have a sidebar showing the websites bookmarked in my toolbar. In researching how to do this, it said I needed to use the menu button at the top left of the address bar to do this. The only thing is I have no menu button! Can you please tell me how to add the menu botton to my address bar so I can use the options it affords. I have added a screenshot of this Firefox window so you can see there is no menu button here.

I would very much appreciate it if you would get back to me as soon as possible so I can make Firefox more workable for me.

Thanks in advance for the help!

I downloaded my bookmarks from my Desktop. I emailed the file to my laptop. How do I integrate this new .html file into my laptop? When I open the .html file, it comes up with a very nice list of my websites by name and they show as a link. Now I need to get them from the .html file and merged into the laptop. Can anyone point me toward the right help files on Firefox or tell me how to do it? Thanks a lot in advance. Mark

I am trying to figure out why my Firefox tabs keep crashing every few minutes. I have reinstalled Firefox and I am still getting the same issue. Please let me know if there is any solution.

I have installed Firefox recently after migrating from Opera GX and I noticed I cannot control Twitter videos volume, only mute. I already tried to reinstall, tried with Troubleshoot Mode and I can't fix this. Is there a way to fix?

I have a gif showing the issue: https://i.gyazo.com/f73c4de39df3161e527f754ed694772a.mp4
