Firefox supportforum

On Mac OS 14.4 Firefox hangs on launch and crashes, requiring "Force Quit" when I try to Refresh or Troubleshoot. Uninstalled and reinstalled multiple times, and restarted computer several times. Have spent several hours trying multiple community suggestions to now avail.

I am not a programmer, but am able to follow instructions. I clearly need someone to hold my hand and walk me through the solution. (I even checked out the Kaspersky suggestion, but cannot install it because Firefox cannot connect to the Internet.)

I have downloaded and saved "Raw Data.docx" and "Application Basics tex.docx" from one of the crash reports.

P.S. On this question form Firefox guessed that my operation system was Mac OS x 10_15_7, but it is 14.4

I used to be able to access all bookmarks from the Library icon on the address toolbar. Now, it only shows a list of what it labels "recent bookmarks" (the bookmarks shown are really not recent). I would like to be able to open the Library and access all bookmarks, which is the way it used to work. I will attach a screen shot to illustrate what I mean.

When I open Firefox. Firefox Will NOT open any websites. If I disable ublock origin then enable again Firefox works but I get all the ADS. What I have to do is: Close firefox and restart Firefox but then I get this message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." Sometimes I have to restart Firefox as many as 10 times before Firefox works. I got to the point where I stop after the second try and just switch to Brave browser.

Before: Firefox use 99%. Brave Use 1% Now: Firefox use 75%. Brave use 25%

After updating my openSUSE Firefox package from version 122 to 123 every frame inside each window started to have weird grey overlay of scrollable area. I failed to find any description of such a thing happening, let alone how to get rid of it. I tried removing build-in distro-default preferences and had complete audit of all my custom preferences in about:config but none changed that behavior. I even updated to 124b4 but this also haven't changed anything. Naturally, nuking entire profile is not an option, I might as well replace the whole browser. So, how do I get rid of this thing?

Hello. I just wonder why firefox connects to bookmarks url's right after you open firefox? Opening page is always set to:about:blank. I discovered this when I want to know some netwrok traffic from my laptop and I wanted to know which software causes that traffic. And then I noticed that only open firefox it takes connection to bookmarks url even it does not open any web pages - because the opening page is about:blank

Hi I have a problem with the configuration of my Firefox. (I hope it is not something more serious like a malware or a security break)

Firefox version 124.0 (64bit) Os: Windows 10 Pro (64bit) 10.0.19045 Build 19045

Step to reproduce

1. 1. I go to: https://wwws.tesoro.es/index.aspx (website of the Spanish gov)
2. 2. I click on the link: Cl@ve in the center of the page (that should bring me to https://pasarela.clave.gob.es/Proxy2/ServiceProvider)
3. 3. I receive an error page "Did Not Connect: Potential Security Issue" "SEC_ERROR_UNKNOWN_ISSUER" (see the attached screenshot)

Things I tried

• I followed the same steps on Chrome on the same machine

The website works

• I followed the same steps on the same Firefox in Incognito mode on the same machine

The website DOESN'T work

• I followed the same steps on a completely new Firefox profile on the same machine

The website DOESN'T work

• I followed the same steps on Firefox on a different machine (same Firefox version, windows 11)

The website works

Mod - please delete. I couldn't find a way to delete my question so I edited it. I had an issue but I think it's due to my Firefox being Enterprise managed. I tested the same thing on my personal laptop with Firefox and no issue.

Thanks!

I get this error in my console XPCOMGlueLoad error for file /usr/lib/firefox/libmozgtk.so: libwayland-client.so.0: failed to map segment from shared object Couldn't load XPCOM.

For some reason, in my firefox profile, when I try to access "https://accounts.google.com", it open on new tab with a specific container, while other url keep open with no container. I've never configure this behavior, or found a setting to fix it. It only happen on my current firefox profile. If I create new profile, this problem didnt occurs.

When I attempt to login it just spins and nothing happens. Works on Safari and Chrome.

Opening DevTools I can see an error about "CORS Missing Allow Origin" but I don't have this issue with any other browser. I have disabled/removed all my browser add-ons and the issue persists. I have no problems logging in to any other site.

Refer to the attached image ... I've looked thru history, bookmark manager, all the settings, and so on and this site cannot be removed from the URL suggestions! Your documentation suggested clicking a button on the far right, but it's non-existent. You also suggested to scroll down to highlight/select the URL and SHIFT+DEL, but that does nothing. I've been trying to get rid of this obsolete website link for over a year and it's an absolute mystery where the link is coming from and bugs me.

Looking forward to more suggestions.

I've been using Firefox and it's saved numerous passwords. However, these disappeared suddenly. Through testing, I discovered they reappear when I restart Firefox in Safe Mode (achieved via about:profiles => restart with adds-on disabled). Yet, re-enabling add-ons (restart in normal mode) causes the passwords to vanish again. Interestingly, disabling the add-ons in normal mode doesn't restore password access.

Looking for solutions or insights.

I have migrated from old MacPro to new Mac Studio. Firefox ESR version 115.9 has migrated with it. I've downloaded the latest Firefox but it operates independently of the ESR version. How do I ensure new version has all log in, contacts and history?

Two issues using latest version of Firefox with Windows 10.

These 2 issues have occurred in the last few days

First I cannot attach my files to my emails using Gmail. I'm able to do this using Edge or Chrome

Second, normally when I used to start typing the name of my correspondent it would automatically complete. This is no longer working. I'm able to do this using Edge or Chrome

the attached printscreen shows both issues

Hello,

For an unknown reason, my firefox sometimes is really slow to startup.

It can take up to 10 minutes before the webpage start to load. My hardware is not that bad. I try to use the "performance" to capture the issue : https://share.firefox.dev/3x2rgHj I don't know if there is something to see because, the tool is also slow.

It happens on 3 different computers on linux.

I try to disable all extensions and without telemetry but nothing change. I'm reporting the problem now but it's much older

If you have a idea to fix this issue please share because it's really annoying.

I don't know if that was supposed to look like, but when rendering MathML in Firefox 124.0.1 when one uses "mtable" element the browser adds very huge gaps around.

The included image shows output for the following code:

<math display="block">

 <mfrac>
   <mi>A</mi>
   <mn>2</mn>
 </mfrac>
 <mo>=</mo>
 <mrow>
 <mo> ( </mo>
 <mtable><mtr><mtd><mn>1</mn></mtd><mtd><mn>0</mn></mtd><mtd><mn>0</mn></mtd></mtr><mtr><mtd><mn>0</mn></mtd><mtd><mn>1</mn></mtd><mtd><mn>0</mn></mtd></mtr><mtr><mtd><mn>0</mn></mtd><mtd><mn>0</mn></mtd><mtd><mn>1</mn></mtd></mtr></mtable>
 <mo> ) </mo>

Hi, All my tabs and many pages are appearing in an unreadable nonsense font. This page is ok, except for the tab and url; others, such as the settings page, are entirely garbled. When I copy a snippet of this and paste elsewhere, it shows up as English; so it is a display issue, not a new language.

This started on booting the machine today, after some OS upgrades yesterday. (to OS 13.1). I've tried restarting FireFox.

I can't read the settings page well enough to change much there. But this seems like a different issue anyhow. Help please!

thanks Sarah

A few weeks ago I saw an Mozilla ad for a new Mozilla software product that cleaned up your PC and made it run better. The price was around $125.00 (I don't remember that exact price). It said that I would receive an email from Mozilla with download instructions. it's been a few weeks and I have not gotten any email. Does anyone know if Mozilla offers any such software or did I get scammed? I'm pretty good about seeing scams but Ive used Firefox and Mozilla for years and trust them. Maybe that's why I wasn't as careful as I should have been.

Thanks for any help that you can provide. Ron
