Firefox Will Not Open Despite Trying Several Solutions (Windows 10)

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

Windows 10, Firefox 123.0 (64-bit)

It's so bad that I might have to stop using it entirely.

I've tried creating new profiles, disabling all add-ons, and disabling Enhanced Tracking Protection; none helped.

https://drive.google.com/file/d/1DX19hX88Hz_XUbsd0dAljiiiKY_XUUN_/view

As you can see in the video (about the 00:16 mark) it randomly stops properly loading pages from the website, even in new tabs. The only temporary remedy is to either close and re-open FF, or press Ctrl+F5 (which I did at the end of the video).

I must add that it can happen even when loading the website for the first time in the session.

Every day. Videos won't play. sometimes one restart of firefox will fix it. sometimes multiple restarts are required before it'll work. The loading bar at the bottom of the video (on the seek bar) indicates the video is loading but it won't play. There have been times where I have disabled every single add-on and it would not work. Add-ons do not seem to be the cause. I have tried it in a private browser window with no joy. I have refreshed firefox, I have uninstalled and reinstalled it. I have tried disabling my antivirus. I have tested videos on websites in other browsers with no issue. The issue seems to be with the video player itself. overlays seem unaffected, I can use the seek bar and it shows the captions. I have tested different websites including Youtube, Vimeo and Steam. I tried many tens of times to get it working today to no avail. finally when I closed nearly all my tabs, the video worked (but I had also opened TOR and run avideo in that), I am not sure if this is the cause. If the cause is having multiple tabs open, this is an issue for me. I have a learning disability and likely ADHD and I have a set of tabs as my homepages so I don't forget things. If It's not the mutliple tabs, then what else can I do?

Firefox freezes when handling tabs

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

Hi everyone,

lately I started experiencing a font-family-related issue. On certain websites the font-families/styles look broken. I tried troubleshooting the issue by myself without any luck. What I did so far was reset my Windows fonts to default, reinstall Firefox and look what font-families are loaded through the Inspect tool. If I opened the same web page in Chrome the font looks OK. Two websites the issue is most visible at - support.fiverr.com and gmail.com when someone replies to my e-mail.

Please find below a screenshot of what I mean

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

  • My mail client is completely unaffected and is behaving normally.
  • I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
  • Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

I upgraded to 108.01 three days ago. It crashed 3 times in the next two days, accompanied by that popup you get informing you of the crash.

For years I've been using the extraction method of the executable to create a Firefox portable application. Upgrading only involves the install folder. The profile remains untouched, unaltered.

I had an incident of profile corruption a couple months ago, with basically Firefox launching with most features not working, i.e. toolbar buttons, toolbar menus, etc. Yesterday, for a short time, aside from two crashes, I had a similar experience with the buttons, but not quite the same. My default built in Firefox buttons worked, but my extension buttons didn't. I also noticed on a page that I regularly visit, Ublock origin wasn't doing it's regular job of blocking, and the Ublock button was non-responsive.

I'm also in the process of using the Brave Browser for the first time. The reason I'm posting this here about this subject, including a Brave experience, is that at the same time I was experiencing the Firefox erratic behavior, Brave was crashing as well; freezing; tabs not loading.

Considering the Brave tabs not loading, and the temporary Firefox Ublock origin failure, etc., I'm wondering if there might be something in common here? Maybe an internet connectivity issue at the time?

Ever since Firefox updated to the new version I've been having constant crashes. I've tried restarting in Safe Mood which doesn't help. Pretty much Firefox will open, say it's not responding, and then by the time it looks like it's about to restore my tabs it crashes. I had to do a refresh and transferred the backup files from an older session which worked, but then it eventually crashed again. I uninstalled and reinstalled Firefox and tried opening my older profile but it keeps happening. I really need to restore my previous session. There's nothing with my computer that seems to be causing it. I did have 2 windows open with about 8,000 tabs total which I'm sure could be part of the reason, but it never really had trouble before and only just started crashing since the update. Is there any way to fix this without starting over? I read that this is a bug that others have dealt with previously.

Some additional information. I'm on a 64-bit Windows 10 PC.

I love how the new tab page clearly states "Never fear losing a closed tab again.", and then when a window disappears it is followed by zero history to recover it. I have not restarted Firefox, let alone my computer since the last time the window was seen (about half an hour ago). It's not in my Alt+Tab tray hiding. I don't even remember closing the tab--though it's possible my keyboard double pressed when I was closing another window. (It's old and has a tendency to double hit keys). But now I have lost a window with at least 20 tabs open--mostly things i had yet to deal with and don't remember the URL to get back to it.

What use is my history and ability to reopen accidentally closed windows if everything just disappears from it within half an hour after the window could've been closed?

I would prefer to keep most of my browsing on Firefox, but I can't constitute that if I'm going to lose months worth of saved tabs randomly.

In Firefox, the mouse becomes partially unresponsive to elements in the browser and on web pages. This happens after 15-30 minutes after starting up the browser. Common symptoms include:

- Unable to drag and drop elements properly, including text after highlighting it. - Sometimes, the mouse continues to hold elements while dragging. Pressing ESC temporarily fixes this. - Dropdown menus on websites do not drop down when hoovering over them - Other items on websites don't display items when hoovering over them

I have tried:

- Different mouses, including my laptop's trackpad - A Firefox fork, namely Waterfox, but it still occurs - Limited testing with other browsers. No problem occurs - Limited testing on desktop. No problem occurs - Entering Troubleshooting Mode on Firefox - Clearing cookies and cache - Reinstall Firefox (including installing from command line instead of the snap store) - Updated Firefox - Refreshed Firefox - About:Processes doesn't show anything using more than 10-15% of CPU at any one time - Limited testing with a new Firefox profile. No problem occurs - Disabled WebGL and Hardware Acceleration.

Temporary fix: Restarting Firefox, but the problem re-occurs shortly after use.

Using Ubuntu.

Any help would be greatly appreciated.

I saw a message that my Add-ons were disabled, and when I checked the Add-ons Manager , each of my many Add-ons had a message similar to: "1Password – Password Manager could not be verified for use in Firefox and has been disabled. "

Some searches in the forums suggest that that this can be caused my a certificate at Mozilla expiring, I seem to be the only one with this issue at the moment. All of my Add-ons came through the Mozilla store .

I am using version 123.0.1 (64-bit) on OpenSUSE Leap 15.5, and as far as I can see all of my updates are current (and from the official sources.)

What should I do next? I expect I need to wait for a certificate update or something at Mozilla, but if/when that happens how do I verify it did and re-enable my add-ons?

Community, same problem, don't suggest way to close, removing files from certain folders. This is an error in the program, it should direct upon opening to my home page!!! The last two updates did not correct this error as a previous one did. The line of code directing Firefox upon opening should direct to my home page. I have tried other suggested methods to no avail, after removal of those files, close, reopen it will go to home page....but only once, then back to try to get my pages back. Even if closing on home page, reopening will not go to home page. Real solution please.

Using firefox version 102.3.0esr (64-bit) on openSUSE Leap. Since a couple of weeks the opening of external links by clicking a link from any application or when running firefox <url> is taking about 5 seconds when the browser is already open. This was always instantly and still is on same setup on laptop machine, both are updated to the most recent OS packages.

Had it yesterday, happened this morning after the restart and just NOW, when I entered 6 lousy tabs, and they are NOT in the recently closed list either.. wups, gone, no tabs, setting has a check mark on open previous windows and tabs. Within 24 hours, lost the tabs three times with a non reported crash and Firefox closing itself with no warning.

I honestly do not think I am responsible to keep a backup of my browser history, I expect a browser to do that. I switched from Opera to Firefox not to long ago.. even Opera is a security risk.. at least it doesn't delete your tabs just for fun.

Very simple.. that happens once more and i am OFF this browser....
