i cant get firefox to open main page no matter what i try. Ive download it a few times and then it ask me to no let it fix it i did and then it still wont open.use firefox more than any site. ty if you can help.

Dear fellows,

I did lost all history data after a previous update, my user got corrupted data and somehow I did manage to import the info into Edge browser. To my surprise after I reinstalled a clean Firefox, it only imported back 3 months of browsing history. Topically, average user keep a computer 3-4 years.. I don't know from where developers came with the idea of limiting to such a shot interval. I have thousands of browsing history links from more that 10 years kept and I need them all.

Tried to increase the number from about:config, but there is an option only for Chrome which I never used and always hate :)

I did installed Chrome to convince myself about it's ingenuity, even if it was not necessary. It does have import option only from Microsoft Explorer, no Edge.

If there is a solution for importing a longer period and high number of entries, please share it.

I'm not an IT expert, but I can manage consoles if there is an even deeper option to modify config files.

Thank you in advance!

I've been using a Rewards site regularly (3/4 times per month) for several years without problem. This weekend the attached pop-up appeared. It makes no difference whether I select Resend or Cancel, the program just re-displays the pop-up trapping me in an endless loop. The only exit is to close the window and abort the process. I was able to complete the task without any problem using Edge instead so it appears to be a Firefox specific issue. I haven't consciously changed anything since last using the site successfully on 24 May. Any help/suggestions appreciated.

Lately, I have been getting a pop-up error when I start and close Firefox. The error reads: "XULRunner Could not determine any profile running in backgroundtask mode!"

I have found posts such as this one: https://support.mozilla.org/en-US/questions/1398228 and other posts suggesting to disable the scheduled task in Windows Task Scheduler, but none of the solutions have worked thus far. Anyone know of any other solutions?

In Firefox, whenever I go to nab.com.au and then click on Login on the top right, I hear a constant stream of static noise coming out of the speakers.

In Chrome, when I just visit nab.com.au that same noise starts.

I have a set of Bose speakers connected via an optical cable.

This behaviour doesn't happen on all sites. Just some. As soon as you close the tab, the noise goes away.

It's driving me absolutely nuts.

I have installed firefox in my laptop for years. after latest update, firefox runs just fine only for the 1st time, then after closing the app / restarting the laptop, firefox keep giving error (attached) I have tried to refresh, run troubleshoot mode, uninstall and reinstall again at one point I was able to recreate the issue only after reinstalling firefox 126.0.1 portable version and then syncing to the profile ( run ok for 1st time, then it broke down after closing it) The problem also seems repeatable using firefox 115 protable Now, I tried to reinstall the portable version from scratch, it keeps hitting same error from 1st run

I have also double check the firewall and antivirus to make its not blocking All other browsers works just fine

More than half of the websites are broken when viewed in Firefox now E.g. theguardian, youtube. It takes way too long to load and most of the time it's only part of the page. The same websites work on Chrome and Edge without any issue.

And then I try to upload screenshots (.JPG) to this form and it doesn't work?

I have recently been getting an error message when I open Firefox saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem". This has been happening since I clicked on a mail in Mail to unsubscribe from a spam/phishing mail list, which seemed to result in me installing Firefox Private Browsing, which I had never subscribed to. I have tried uninstalling Private Browsing but there is no way of doing that. I have even uninstalled and then re-installed Firefox completely but I still have the same problem. Because of the problem I have now lost all my bookmarks and history, and am unable to create new bookmarks and history. I have been on the help forums and seen that I can Disable Private Browsing by going through my anti-virus (Avast), which I have not yet tried because what I would really like to achieve is uninstalling and not having Private Browsing on my Start menu, rather than simply disabling it. Anyway, would disabling it solve the bookmarks and history problem ? Can anyone give me the solution ? Thanks. As you may gather, I am not very techno so you would have to give me the idiot's version of any instructions or advice.

hard drive failed on windows 10 pc, new drive put in & window 10 reinstalled with Edge browser (by experts) What do i do to get firefox browser as my main browser back with all my bookmarks etc & firefox VPN ?

Do I just download firefox installer & sign on & all bookmarks etc will be there?

Thank you for your help, Tony

When ever I play a game, the video I have playing (yes I need that stimulation) all of a sudden just freezes I can hear the audio but the video just freezes unless I click back onto the browser

Mein Laptop reagiert nicht, wenn ich mich über lockout abmelden will. Mir wird stets die Seite "Fehler: Gesicherte Verbindung Fehlgeschlagen." und nicht wie vormals beim öffnen des Laptops. Wo liegt der Fehler?

For the last few weeks i've noticed youtube vids buffer but then sometimes stop and when the video reaches that point on the bar it skips about 5-10 seconds, then contines to buffer like normal, so I have to use the arrow keys to go back to see what I missed. It is very annoying. Happens almost 1-2 every day at random times. My wifi speed is good. I've cleared cookies and caches, turned off enhanced tracking protection for youtube, i've even increased perfomance settings for intel graphics in my pc's power manegment plan. Nothing! Can anyone help, thanks.

Keep getting this response from browser or bank log-in site: "You were signed out due to inactivity, but you can log in again whenever you’re ready."

Able to access site on MS Edge using same pwd and user ID

Dear Firefox support community

Greetings from southern Germany, near Lake Constance :-)

I have issues since a few months that Firefox loads website only when I actively click on the app and put in foreground. Then the tabs start loading. Why is that?

After startup of Windows 10, I usually run a little batch script of mine starting various applications such as Outlook, Notepad++ etc, including Firefox along with my favourite websites, just like this:

start "" "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Firefox.lnk" https://de.wikipedia.org https://www.google.de [and more...]

So Firefox loads and opens all the tabs in the background, while other apps such as Outlook or Notepad++ come in the foreground. I read mails etc. before I decide to check e.g. Wikipedia. So it might take 5 minutes after Firefox got opened before I actively put it in the foreground. THEN I see no websites got loaded, and THEN Firefox starts to load the websites, which then takes the normal amount of time of a few seconds.

I wonder why Firefox does not load all my requested websites directly after start in the background.

An annoying side effect is, when still in Outlook and clicking on a website link in an email, it won't open in Firefox, most likely due to that reason that Firefox still waits for all the other websites to load. I need to put it into foreground, wait for the loading process to complete, and then go back to the email and click on the link again.

Any ideas would be greatly appreciated!

Many thanks in advance for your assistance & Best regards Volker

There are a bunch of obsolete suggestions on opening FF without address bar, menu bar, etc., and kiosk mode.

I do not want Kiosk mode, but do need ability to open it via command line so that only the title bar (and borders around the app.

The most current available entry on the matter in the Mozilla site no longer works (at least for me) --

firefox.exe" -ssb https://www.example-site.html/

Also even if it did, not viable to update all FF users as these are customers, and they won't, simple as that. Chromium browsers just work by passing the command by default.

This is for use to launch a local help/users guide from a Windows application. Can do so on Chrome/Edge, but leaving out FF is less than ideal.
