Firefox Support Forum

I run the latest Firefox (v122.0.1) on Windows 11.

Since last week, FF takes 14 minutes to start the first time after a boot. :-( Usually FF starts in ~3 seconds.

I reboot the laptop. I wait a minute. I start FF. Nothing happens for 14 minutes. Finally the browser window suddenly appear and everything is working normally. I exit FF (no remaining firefox.exe processes are running). I start FF again. Now it starts immediately as usual. :-) But: I reboot and start FF. Again, it takes 14 minutes to start. This is reproduceable every time.

I haven't tried to *solve* this by refreshing FF or simillar. Right now I'm more interested in debugging this and finding out what is wrong.

I found https://profiler.firefox.com/docs/#/./guide-startup-shutdown which states how to automatically start the profiler at startup.

12:40 I boot the computer, login and wait a minute. 12:43 I start CMD.EXE and run:

 cd c:\Program Files\Mozilla Firefox
 set MOZ_PROFILER_STARTUP=1
 set MOZ_PROFILER_STARTUP_ENTRIES=20000000
 set MOZ_PROFILER_STARTUP_INTERVAL=100

12:44 I run:

 firefox.exe

No GUI appear. (it won't appear until 14 minutes later) I open the Task Manager and see one (1) firefox.exe process, taking 0% cpu. (pid 17668) 12:48 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:50 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:52 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:54 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:56 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:58 The browser GUI finally appear. Everything is now normal. It is showing one (1) tab with my start-page (google) just as it should. (my Task Manager now show 12 FF processes running, with various options) 12:59 I click the icon to stop the profiling.

I open the profile. [Profile Info] says:

 Recording started: Sat 17 Feb 2024 12:58
 Recording length: 1m12s 

So my profiling data don't show what happens between 12:44 to 12:58 :-(

Just for the sake of it, I'm attaching a pic of the first 10 seconds of the profile (at 12:58).

PS: Between 12:44 and 12:58 no FF window exists at all. Alt+Tab show no FF and in Task Manager I can't do any "Window" management, it is greyed out. I.e. no FF window exists for this process.

Question 1) What should I do to debug what happens between 12:44 and 12:58?

Question 2) How can it be that it takes 14 minutes to start FF from scratch (boot) while it starts quickly (~3 seconds) if it has been started once? I mean, all firefox.exe processes are gone when I exit FF, so starting FF again should be like starting from scratch, but apparently something is different.

Question 3) Is it normal that a FF, with only one tab (https://google.com/), run 12 processes in Task Manager?

Hi there. I use mailjet for sending email newsletters and campaigns. The images that i was uploading into the mailjet templates where displaying fine both on mailjet and when sent to mozilla firefox users.

The problem is that for 10 days now; when i upload images in mailjet and sending newsletters; the images are not displaying in mozilla. In contrast, when i use chrome everything displays fine, both mailjet and email accounts.

I had a long chat history with mailjet support and they requested to follow these instructions to fix this issue first: https://documentation.mailjet.com/hc/en-us/articles/360058211453-Why-are-my-images-not-displayed-missing-in-the-Email-Editor I did this but i had no success so they requested me to use chrome instead of mozilla. But that is not the solution of the problem because this must address all different browser users.

Can you please help me on this?

Thank you,

There used to be an extension called "IE Tab". It allowed you to right click on the link, and open the site in a tab, using Internet Explorer, for sites that didn't work properly in Firefox. I was wondering if anybody knows of any similar extension that would do the same for Edge? I can't open Twitter (X) using Firefox anymore, but I can open it using Edge. I don't like Edge (obviously), but I have no choice. Thanks in advance!!!

Last time I tried backing up my bookmarks, they were saved in a file that was basically a list, a list that can't be imported back to Firefox bookmarks, but just a list. I would like to know if there's a way to actually export and import bookmarks with one click, rather than me having to add 200 pages from the list manually. When I tried importing the file, the list ended up somewhere random and not where bookmarks are

Very often, recently, I can't communicate with an organization via their form on the WWW internet. After minutes of frustration, I change to a Chrome or Safari browser on my Mac, and it works just fine.

One of the problems is when filling out a form, Firefox says over and over there is an error. Safari takes that same data just fine, no error.

There are others, but I'll have to wait until Firefox fails again since it's not that easy to reproduce what happened days or weeks ago!

Firefox is my default browser. Up until a few months ago, if I clicked a link in an Outlook email, it took me to Firefox and opened the site. Now it takes me to Microsoft Edge.

At the same time, another problem arose, albeit minor. When I am using Firefox and attempt to email a link, there is a message, "Navigation failed" and a blank screen appears. This is not a big problem, since when I open Outlook the email is waiting to be sent. But this too smacks of something Microsoft is doing to sabotage the competition.

Hi,

I wish to provide a co worker with access to some websites (and provide the site passwords), this will involve - from what I can see setting up a separate FF profile (that we both sync to - by using a Firefox Account) on my PC, somehow copying the bookmarks and passwords from my general profile into a new 'co worker' profile, the co worker (via sync) would then see the bookmark, and then hopefully also have the password available.

I can see how to export/import all my bookmarks, or have her sync to my 'general' FF account quite easily, but I only want to give her access to work related bookmarks and PWds.

Any thoughts appreciated.

Every time I open a youtube video in fullscreen, firefox crashes. `about:crashes` says "No crash reports have been submitted."

Some information about my system:

• Firefox version: 122.0.1 (64-Bit)
• Macbook Pro M2
• MacOS Sonoma 14.3.1

If there is a way to get more information that you would require (like logs) please describe how I access them, so I can share them.

Hi dear Community!

As of recent, my AntiVirus software is flagging Firefox.exe (Full path: C:\Program Files\Mozilla Firefox\firefox.exe) as a vulnerable application. I have been using firefox for years (Because I love it, you guys are heroes) and i have been using Kaspersky for years. Firefox has only been flagged as of recent.........

I hope someone knows why, has this too or can calm my paranoia

Some Additional information:

Have you clicked any suspicious links? No i have not. The links i have visited were all https, checked and acknowledged by Kaspersky and i can say with full certainty that the sites were legit

Have i downloaded any files as of recent? Yes, but from reputable sources and always checked using Hashes and validating using KSN (Kaspersky security network).

(For the Mods, im sorry for previously posting this in the wrong forum.)

There are sites, including yahoo that all my comments are coming back as "comment failed to publish" or other sites where comment section just not there. Seemed like this started happening after a recent Firefox update. I have contacted web sites, my protection service and they have, after research come back with problem is Firefox. If there' something I've done or not done to have this happen, let me know. It DOES NOT happen when I use, as example Edge or anyone else. Thanks......Mike

Hallo ich möchte das Firefox sich beim starten des Pc alleine hochfährt. In den Einstellungen soll es dafür eine Option geben die bei mir aber nicht vorhanden ist. was kann ich jetzt machen?

firefox is using so much memory that it is causing lag and loading problems.

i know that the root of my problem is that i have an unholy amount of tabs open all the times but if i go into the process manager for firefox i can see that the memory problem is actually usually only 1 or 2 tabs that are using over 1GB of memory. this has only been a problem in the last few weeks so i am not sure if something has changed on the firefox side of things.

I looked into tab unloading and this seems like it would solve my problems. however the unloading process only happens automatically when the total amount of memory that firefox is using approaches the maximum amount of memory you system has available. with 32GB of ram and firefox reaching not even 16GB when completely stretched the automatic process will likely never hapen. yet firefox is still using enough memory that it is causing itself problems.

i dont really want to have to unload my tabs all the time to keep firefox's memory in check. is there anyway to lower the amount of memory that causes firefox to automatically unload tabs? i have seen extensions that say they will sleep tabs that are not being used. however they all seem to just sleep tabs that are not currently in use rather than sleeping tabs that have not been used that day.

i feel like the tab uploader is such a good feature in firefox that i would love to be able to use it to solve my problems. however i am not sure how to make this happen in the laziest way possible.

I use 1 Firefox account on 3 devices (2 PCs and a smartphone). On the first PC, the number of synchronized passwords is 1126. On the second PC - 135 (similar on a smartphone).

I pressed the "Synchronize" button many times, everything works, new tabs appear, but there are no passwords. What to do? I'm afraid that if I log out of my account on the first PC, I will lose all access forever.

Vimeo "manage videos" page displays momentarily with controls below the embedded video, as it should, while loading, then it switches over to show the title of the video, making it impossible to change settings. This behavior repeats if I refresh the page. It still occurs after clearing the cache. It does not occur in Microsoft Edge or Google Chrome.

Something went wrong w/ the mouse, some of my tags disappeared & wasn't able to recover them via Ctrl+Z, so I decided to perform my 1st [Restore] (never had to do 1 before), since I had just recently done an [Export Bookmarks] & a [Backup]. Everything seems to have gone Ok, except that for every tag, all of the bookmarks listed under the [Name] column are duplicated. When I right-click & [Show In Folder], they both show in the same folder. When going onto their folder, they are only shown once, so there are no duplicates there. When I attempt to [Delete] 1 of the 2 duplicate entries they both get [Deleted], so I can only conclude that they are 1 in the same. But the question remains, "How can I fix this duplicate condition?"

Another related & interesting behavior is that, from any bookmark folder where you can clearly see there are no duplicated bookmarks, when you do a [Search] from the top-right-hand search-box, the "results" are also "duplicated", although you might need to sort them by clicking on the [Name] column control. So, I can go to any bookmark folder & clearly see that there are no duplicate bookmarks, but when you do a [Search], that's when you get duplicate entries. That leads me to believe that this is the result of the [Search] function, & thus for some odd reason the [Search] is generating "duplicate entries". And then perhaps, both the [Tag]s & the [Search] function are related.

Also, this "duplication" does not happen on newer added bookmarks, after the [Restore] was executed, & it's only a phenomenon that affects those bookmarks that were saved by the Bookmarks' Library [Backup] function, & thus this anomaly was introduced by the [Backup].

Actually, I just realized the problem is more complicated than I thought. The reason any search results in "duplicate bookmarks" is because there are 2 sets of folders, 1 set above the other, & if you don't scroll down all the way you won't see it. So that's why there are actually "2 Sets Of Bookmarks", because there are "2 Sets Of Folders", 1 above the other. The problem is that when you delete any "Duplicate Bookmark" you delete them both, & not just 1 of the 2 bookmarks.

I wonder if it would work, to "Delete All Bookmarks" & then do a [Restore]?

Could "Mozilla Support" answer that?

Don't know why every time I attempt to [Post A Reply] & get an "Error",... So I'm going to post my reply right here,...

Fix: (2024-02-19) Of course, I did some testing before I concluded what was the best approach, but since I noticed all of the "Bookmarks Folders" were duplicated under [Bookmarks Menu], an easy fix is to go to the "bottom duplicated folder", right on top of the [Other Bookmarks] folder, & "Select It" (by clicking on it) & [Delete] it (w/ the [Delete] key on your keyboard). Do this 1 by 1, until you reach the "bottom folder" of the bookmarks' folder you certainly don't want to delete. Close Firefox & then reopen it - to make sure Firefox takes care of any garbage-collection. Then do your Bookmarks' Library [Export Bookmarks To HTML] followed by a [Backup], & you are good to go.

Actually, I don't know what introduced the error. Don't know if it was Firefox's [Restore] function, or it could have been me (by accident) w/ some "unnoticed & unexpected" move of the mouse/trackball, which accidentally duplicated all of the folders w/o me noticing, & that is why all of the "Bookmarks" were "duplicated".

Happy Firefox Browsing,...

I do not know how I got there, but I somehow got into a situation where I could push a button 'Refresh', or in Dutch 'Opfrissen'. Firefox then started to remove settings and extensions. Which is all well documented if you know it. But the user interface is just crap here. Especially in Dutch. Because 'opfrissen' is something that sounds totally innocent in my native language. I at most expected it to remove some cache memory. The last thing I expect pushing a button with that name is that it does what it did, without any warning! PLEASE change that. And please do not translate it with 'opfrissen', just explicitly say: Go back to standard configuration and remove extensions. I am not dumb that I could not understand what that should do. Opfrissen.... Pfff, please change at least the translation!

And I got really angry when it happened!

Dear Sir/Madam

I have set up a new Microsoft Surface pro 7 with fresh Win11 23h2 and office installation.

The latest Firefox 122.0.1 has been downloaded.

Problem:

When i sign in to my Microsoft 365 account for the first time everything goes smooth and get all authentication steps.

BUT

1. I never reach the Microsoft 365 page and return back to Microsoft log in page

"https://www.office.com/?trysignin=0"

2. if I insist in Trying I get in a loop and i get the error message "AADSTS50196 authentication error,"

3. I have tried to clean Cookies cash. The only difference now is that i do not get in that indefinite loop but i have to reenter the sign in credentials and again reach the log in screen.

4. I have entered the office.com, Microsoft.com, hotmail.com as trusted sites but problem same

5. No issues in that particular Surface pro to sign in Microsoft 365 site via edge

6. No issues to sign in Microsoft 365 in my other computers via Mozila. It happens to that particular surface new installation

Any help/Troubleshooting will be appreciated

I am one among many who keep a lot of windows open for reference. When my compootie shuts down inadvertantly I am avle to use "Restore Session" to get these back. But occasionally the system shuts down and I am unable to restore anything, and this can cost me tens of hours os referencing, and untold hours of productivity.

Could you save the open windows in an easily accessible file that we could use to restore previous sessions? This would save a lot of us considerable grief.
