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 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 How to remove extension symbol from toolbar? ^(see image): https://i.imgur.com/2bh8se5.png Any idea? Thanks

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.

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'm using Firefox 112 on Windows 10. The toolbar contains icons for several extensions that I don't want to see. I click on the >> menu and then Customize Toolbar. That opens the Overflow Menu. It says, "Drag and drop items here to keep them within reach but out of your toolbar." I try to drag one of those extension icons onto the Overflow Menu. It won't go. The dragged icon picks up a circle with a line through it, indicating that this is not allowed or not working.

How can I use the Overflow Menu as advertised, to remove unwanted extension icons from the toolbar? Or is there a good workaround?

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.

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.

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.

Hi, I cannot use wordpress.com. When I click on "log in" it hangs at the redirect and I only get a blank screen.

(Hangs here:) https://wordpress.com/log-in?redirect_to=https%3A%2F%2Fwordpress.com%2F

I've disabled all extensions, cleared cookies and restarted, nothing seems to work. Any help would be much appreciated.

Thanks!

I am getting repeated pop-up windows that say that Firefox has crashed, but Firefox is not running on my system. It is not in the Startups and I rarely use it.

Windows 10 Firefox v110.0

Is this malicious not related to Firefox? Does Firefox have a background task that is not visible on Task Manager? Or what?

Despite have used Firefox for many years, I am still not completely clear on why there are two separate areas for cookie settings, and how everything works together. In Cookies and Site Data: I check Delete cookies and site data when Firefox is closed. In Manage Exceptions, the listed domains I choose will not be deleted, but all other domains will. Correct? In History: I uncheck Always use private browsing mode, and I check Clear History when Firefox closes. In the Clear Recent History box, I uncheck Cookies and Site Settings. Question: Will be above choices in both areas get me where I want to be, which is retaining cookies for chosen protected sites, while deleting cookies for all others whenever Firefox is closed? If this is where a lot of people want to be, why are these choices presented in such a complicated way? If relevant, under Enhanced Tracking Protection I choose Custom, and leave all the boxes checked. The sites I choose to use seem to perform well with this option. Is this Security & Privacy area in Settings in need of reworking for ease and clarity?

OS version: Ubuntu 22.04.1 LTS (jammy), 64-bit (amd64, x86_64). Firefox version: 110.0 (64-bit) (NOTE: the issue was noticed with version 109.0, too)

Firefox package was installed on Ubuntu through 'APT', using the Mozilla Team repository (https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/). It caught my attention that an excessive amount of Firefox related 'DENIED' AppArmor log messages is generated during the browser activity.

According to messages, Firefox is occasionally denied read access to '/sys/devices/' area and read/write access to 'oom_score_adj' target in '/proc/'. Could somebody clarify why would that access be required for regular browser operations? I'm a bit puzzled as I haven't noticed anything similar with the older Ubuntu and Firefox versions. A complete suppression of those messages is also an option as long as there's no negative impact on application's performance.

I already posted this question to Ubuntu forum but seems like nobody there could provide an explanation. I'd appreciate any input or hint.

Following is the sample of referred log messages:

Hello,

this problem started happening around 3 or 4 days ago.

Usually, at the end of the day or before I close Firefox, I "delete browsing history" BUT only the "today" history. I know it's a weird habit (lol), but at least it logs me out of all recent browsing while keeping my sessions with older websites active (typically these older websites include stuff that I use frequently like Outlook, Google/Youtube, Twitter & other social media, Spotify, and a few other sites).

The other reason I do this is that I like my "recent history" to be ordered the way I like, so I can use it kind of like a "bookmark list".

The problem: Since about 4 days ago, each time I "delete history", ALL my accounts are signed out. Note that I don't have the option to delete cookies upon closing checked, and whenever I close Firefox without deleting history the sessions appear to be active.

I think 3 or 4 days ago there was a Firefox update? I remember at the time I was shown the extra tab with the release notes, but I didn't pay much attention. However when I noticed the issue, which was the day after, I assumed it was a new feature of the update that caused all these websites not to recognise my browser and thus ask me to log in again.

So just before going to bed, I tried 1) clearing my history for the day as I usually do, except 2) instead of closing directly after, I would go to the sites I want to remain logged in (in this case I just did Outlook, Youtube, Twitter, Facebook, Tiktok and Spotify), log into my accounts, and then close the browser.

So the following day, it worked "as usual"... almost... that is because when I deleted my history of the day, it logged me out of everything again. But in the "recent history" list, it showed the updated list (with the websites I re-logged into the day before).

So I can't guess what is happening, other that something is messing with my cookies each time I delete history. I even went to check manually to see if I still had the session cookies stored in Firefox and it appears to be the case.

Yesterday I also tried logging into a Google, waiting a few hours, and only deleting the history of the past hour, but the same thing happens, I instantly get logged out.

Additional info: when I "delete history" I only check the first five options (those under history) and not the lower two (under data).

Thanks for your help, and sorry for my English !

After upgrading firefox to 110.0, WhatsApp web failed to load. I refreshed the browser also as I found one solution on forums, but after QR code came but failed to load the chat.

using firefox version 109 and my internet down load manager no longer works, it works in other browsers but not since updating firefox. not sure if i was successful in posting this request prior to this one so will give it another try. thanks

WHERE IS MY BOOKMARKS TOOLBAR??? Every time I update Firefox (now 109), I end up with all kinds of problems! NOW, I can't see my bookmark toolbar. All the help articles tells me how to show it or how to bookmark a page, which I already did multiple times. But this issue is never solved. If I can't get this resolved, I'm going to MS Edge.
