Firefox closing on first startup

This has been going on for a while now, since I want to switch from a certain popular browser to Firefox which I have on another computer, I tried to install Firefox Developer Edition first as I just prefer it and it has some features of which I use sometimes.

However, when I tried to open the browser, it shows a window for like a millisecond then closes. I've also tried with a normal install of Firefox and the same thing happens. I've looked into the Profiles and here is what I've found:

A folder called startupCache (empty) And a file called .startup-incomplete (empty)

Here's what I get when I install dev edition and try to run it:

Two folders, one is dev-edition-default, and the other is dev-edition-default-a very big number

I'll provide a screenshot in this post so you understand all the profile folders.

[https://imgur.com/a/PERMib0 https://imgur.com/a/PERMib0 ] https://imgur.com/a/PERMib0 In dev-edition-default I have the same two files/folders as before, and one more: cache2 which contains the following:

A folder called doomed (empty) And a folder called entries (it has files in it)

In the dev-edition-default-verybignumber I have just startupcache and .startup-incomplete.

If anyone has any idea how to fix neither of my Firefoxes stating up, please let me know!

Decided to switch to firefox from brave. Am completely unable to run Firefox. Doesn't even show up in task manager. I have one split second of a window, then it vanishes. Tried safe mode, tried running as admin, nothing. Brave and edge work, and I even downloaded opera to see if it would mess that up too, but opera booted fine. Running Windows 10 22H2, OS build 19045.3324. Any help is appreciated.

Hi, I have spent hours this morning trying to diagnose a problem with Firefox Update 115. It is Unstable and I can't Stream Music from Youtube or even Amazon Music. Web pages from sites I use everyday are out of order when displaying text as well. It's a real mess. Now, here's the kicker, I haven't been able to stream my music from both aforementioned websites, but get this, if I use the Incognito Browser, Music streams No Problem. Seems like you guys broke something in the main FF browser. I have spent hours trying to debug this and have concluded that your most recent Update has broken streaming links. I can't rollback the Update and that is even more frustrating. Please Fix This. BTW, your Help Pages really stink. Sorry, but they offer no help when the problem is clearly FF. Kind Regards, Joe White

Updating FF, using Mac 10.12.6: Will ESR happen automatically?

I have Mac 10.12.6 on an "early 2009" 27" iMac. I'm waiting for the new 27/32inch iMac until I upgrade hardware and operating system. The release notes with FF V115 say in part " Users on those operating systems will be migrated to the ESR 115 version of Firefox."

I want to clarify that when I update to FF 116, FF will automatically install the ESR version, or will I need to do this manually? Also, will this update take a long time, like FF will be installing a totally new (ESR) version, rather than "just" the usual update?

Hi,

Because numerous things did not work with version 116, I downloaded previous version of the browser and installed it. When it started it said something like "you are trying to use the previous version so some things may not work, would you like to create a new profile?" and there was a choice "yes" or "exit". So I chose "yes" - because how creating a new profile could mean something bad? But it did - it deleted all my bookmarks and settings. I have used mozilla for years, everything was in it. How to restore the bookmarks and everything back? It, by the way, upgraded itself to 116 anyway.

After updating a W10 laptop from 115 to 116 of FF the user started having problems with getting to different websites (sites they worked on/with regularly). The problem is the cert DB. The doc I found says that it is cert8.db. Actually it is now cert9.DB.

What I had to do was go to task manager and kill a task that was holding the cert9.db file. Then I could rename it (cert9.old.db). Then restarted their laptop and FF came up and started fixing the cert file (as expected). This seems to have fixed their problem.

I am currently running Firefox on High Sierra 10.13.6 and have been advised that that OS will soon no longer be supported. I did have an option to do an update to ESR 115.1 in my Firefox app, however I was not home for a few days and when I returned planning to do the update it was no longer available. Now it just says my Firefox is up to date with 115.0.2... how can I get the update to the ESR 115.1? Thanks!

I get no warning when auto updates begin installation. I get notified about 1/2 way through the process. The pc (Win 10 pro 64bit) slows to a crawl for 5-10 minutes, then the install finishes, & then it's another 5-10 minutes before the pc is usable.

I would really appreciate a "update is available" notification, which I would agree to at a convenient time. This is really getting to be problematic. Other browsers that do auto updates don't hose my pc.

Thank you!

Prior to getting some desktop PC upgrades that required a new install of Windows 11 and a new install of Firefox, I backed up my entire PC (yea!).

Now that I have re-installed Firefox, I see that I have none of my saved bookmarks and so I want to restore the Firefox profile - all of it or at least the bookmarks.

I have tried following the Firefox instructions for this, but am apparently not doing it right.

I can't seem to locate the bookmarks file, for starters, in my backed up files. I find the profile but I don't find anything like places.sqlite.

Can someone help me so that I am locating the right (and complete) files, copying them correctly, and then switching to the new/old profile correctly?

Thanks in advance.

I cannot use, update, uninstall, refresh, or reinstall Firefox (and haven't for four or more years). I always get this message: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." But I have (obviously) shut down the computer entirely any number of times in all those years. What can I do? I will be taking college classes and Firefox is one of the few browsers that the college supports.

FF would start to load but never completely finish so I forgot & stupidly did the troubleshooting mode or w/e that put me back to default so LOST all my settings, etc.. Strangely it's back "close" to normal except I was using Passbrow which the icon shows on toolbar but greyed out & I can't get it to turn back on. I have the "Old FF Data" folder but following the steps it doesn't show where profile is stored for me to be able to copy the old data TO. IF I can restore the old profile hopefully that would get it back working ALL as it was...but HOW??
