Firefox Support Forum

Hello all. Since the update to Version 113.0 I have been getting an error in my Event Viewer which is Event 2 Firefox Default Browser Agent . I am now on Version 113.0.1 and still get this error. Firefox is my default browser. Below is an image of what I see in my Event Viewer and also the full view of the event itself. I seem to not be having any problems with the browser but I was wondering if anyone could shed some light on why this is happening or forward to the Devs.

Respectfully, Don

Hello,

When I close Firefox after the last update (current installed version: 112.0 x64 Windows 10), Firefox creates almost 200 processes (in the latest case 177), each using from 17 MB to 65 MB RAM (except one that is using over 200 MB - I guess the main one) using 100% CPU for about half a minute, and in that my PC is unusable - everything hangs. It takes a bit more time to close all of them.

Any ideas what could be wrong and how to fix it?

Thank you.

Since probably 3 or 4 weeks ago Ebay through Firefox has been terribly slow. I have selected the option not to track in the address bar and still the same problem. I run ebay through MS Edge and runs perfectly. Happens to me in 3 out of 4 computers. Only in 1 works ok, very strange...

Speed connection in all of them is at least 200mb/s

Thanks.

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

Hello everyone.

I've been using Firefox for quite a few years now and I'm used to keep my pinned tabs open after closing and then opening a Firefox windows.

Yesterday I noticed that after closing the navigator with the "X" in the tool bar menu, as I usually do, the pinned tabs are not "recovered" when opening again.

This happened randomly without configuration changes involved and drivers/firefox are updated to the last version available.

Moreover, I've tested the same in my notebook and it works just fine, as it keeps the tabs open when a new window is open.

Is there any troubleshooting for this or do you have any idea what could have caused this to happen?

Let me know if you need any additional info. Thanks in advance!

when playing videos, firefox makes the videos much darker and higher contrast than the original videos, as well as maxing out the cpu on my laptop when playing video, started a day ago or so.

This again!

This was resolved about a year ago; now the problem is back, as of updating to Firefox 113.0.1 this evening.

Initially post-update the close tab button was in a weird, random place on the tab bar. I have adjusted the margins to put the button back where it's supposed to be!

I changed :

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 2px !important;
}

to:

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 35px !important;
}

to move the button back onto the left. That may seem like a drastic change but that's the lowest value I could find which produced the result I want.

However, it's not quite the result I want! As of updating to 113.0.1, the tab title itself now disappears altogether on hover.

I have tried to correct this in CSS using the .tab-text and .tab-label attributes, but without any luck so far.

Can anybody help me with this, before I'm forced to downgrade to Firefox 112?

Better yet... how about we just make this an option in Settings, as it should be?!

Why has this started up again? Pdf files are automatically downloading to my computer when all I want to do is look at the file. So many files that now need to be trashed after looking at them. This problem has happened in the past, but was resolved, only now I am finding it happen again. I do not want to have files saved unless I want to save them, not Firefox deciding that any file I open should be saved. I have Windows 11 & Firefox Version 113.0.1. Is there a way to revert to an older version of Firefox?

I've just had to completely reinstall windows without being able to backup my files (I couldn't launch my computer in order to actually back them up) meaning I've lost my recovery codes. I thought this would be fine as I could just sign back into firefox on this new install of Windows but as it turns out I must've forgotten to put my sign in information into my password manager. Again, I thought this would be okay as I still have access to the email I used to sign up to my firefox sync but I got the message saying I'd lose my data which isn't fine and now I'm at a bit of a loss. I've had to use a spare email to make an account and ask here but I'd really love my old account back. Is there any way at all I can get back into my account without losing my bookmarks and passwords? If not, how much information would I end up actually losing? I'm slightly unclear on that part. Do I lose absolutely everything? I'm a bit stressed about all of this ontop of losing all of my old computer files so I'm sorry if this is a commonly asked question but I was struggling to find anything that helped me D:

Any advice at all would be really appreciated thank you so much!!

Two days ago, my firefox browser started not restoring the previous sessions. I changed nothing in the configuration and I don't remember I had a crash. The option "Restore Previous Session" does not appear in the "3-bar menu > history" and it appears grayed in the History Firefox main menu.

What I've already tried or verified following the instructions of mozilla forum: 1) Settings > general > “Open previous windows and tabs” is checked as it always have been; I unchecked and and rechecked but nothing changed; 2) Settings > Privacy & Security > “remember history” is selected. Also tried to Settings > Privacy & Security > "Use custom settings for history" with "Always use Private Browsing mode" not checked. No success 3) I also deleted sessionstore-backups folder under my profile. The new created folder, even after closing some new sessions, has only the "recovery.jsonlz4" and "recovery.baklz4" files. There is no "previous.jsonlz4" inside which seems weird. 4) through about:config I checked that browser.sessionstore.resume_from_crash was true. In fact, I have Firefox in a second computer with no sessions restoring problem. I compared all browser.sessionstore.xxxx variables and the values are the same.

I still have the problem and do not know what to try next. Reset Firefox?

I have AdBLockPlus (free version) installed and have not had any issues until today. Firefox did some updates and now the Add-In is no longer working. I have checked that it is specifically turned on for the websites I'm visiting and I've tried turning it off and back on to no avail.

Block autoplay not working on 112.0.2. I've tried going into about:config and changing settings. Doesn't help. Also under "Settings \ Permissions \ Autoplay" shows default for all websites as "Block Audio and Video" and under Websites "About:Welcome" shows as "Allow audio and video." I've changed the About:Welcome to block audio and video. I've also tried clicking the Remove All Websites button to delete the exception. Neither works. I save changes, exit Firefox, and restart. Same settings as before, and autoplay still starts.

'Screenshot' no longer works. I've used it for years, but this week it doesn't work. I am a woodworker, painter, gardener, handyman, not a computer tech. I want 'screenshot to work like it used to.

When i use a link to an Excel Workbook stored in a GitHub repo the downloaded file is only 6 Bytes - and consequently rubbish. When I do exactly the same thing with Edge or with FireFox or Edge on another computer the downloaded file is complete. I've cleaned up FireFox but it didn't help.

Firefox worked perfectly, but since a few days I can't download anything. I'm using Mozilla Firefox snap for Ubuntu 22.04, version 110.0.1 (64 bits) canonical-002 - 1.0 With Chrome everything works perfectly so I assume it's a problem from Firefox.

When I open a PDF, a MP3 or any file, the "save" option doesn't display anything. Usually it opened a dialog where I could choose the folder where I wanted to download the file, but now I have nothing.

I have only 4 extensions: - adblocker ultimate - duckduckgo privacy essentials - vuejs dev tools - zotero connector

I always had them and I never encountered any problem.
