I am told that when FireFox closes it is supposed to delete a file called parent.lock in FireFox's Profile Folder. The parent.lock file does not delete when I close FireFox and consequentially it will not allow me to open a new instance of FireFox. If what I say is in fact true, what can I do to fix it? If what I say isn't the case, what can I do to make FireFox open a new instance of FireFox once I close it.

I sure hope I have explained this so it can be understood. When I close FF and then try to open it again, I get a dialog box saying FF is already open and has to close first. Not sure if those are the exact words but I was told that the parent.lock was to be deleted and that isn't happening. What can I do? Thanks.

I'm very much computer-ignorant. I'm getting messages on various sites that I need to update my current browser. Downloaded latest Firefox, but lost as to next step. I'm on LinuxMint.

i was using firefox with multiple tabs for most of today, had to shut pc down to run errands. When i restarted pc, firefox would not start, i have it pinned on my task bar/start menu/whatever. I opened my system moniter to see what was going on when i tried to start firefox and the processes do not show up in the process list. I tried a reinstall with the ubuntu software store and no noticeable change in behavior. Not sure how to get into the profile section, the option for it with a right click on the firefox icon does nothing seemingly. Under normal operations i have seen two firefox processes listed.

I had an automatic install of your latest program for my computer and when I restarted it I had lost all my passwords and bookmarks. I would like to know how to get them back,

Got a new laptop. Trying to download Swagbutton but when I click on add the button, the ucontent page opens but never loads. I've never had a problem before. Any ideas/suggestions? I also can't get Swagbucks as my default search engine.

Hello,

today I have installed new OS and new Firefox.

Because I was syncing everything I thought after login everything will be same as before.

Before reinstaling OS I didnt export anything from Firefox. Now I have no bookmarks, no history, add-ons.

I do keep Lockwise on my iPhone and it connected somehow with my desktop browser so I have passwords in my browser now (thank god for that - otherwise I have no clue how they got there).

Is there a way I can restore Firefox (bookmarks and add-ons) to how it was yesterday?

I dont have firefox install elsewhere, just on my desktop.

Thanks a lot for help

I am having an issue with an old firefox process in the background but I don't see one. I need to remove it before I can run the new install copy of firefox 64bit. Any suggestions to resolving my issue.

Ever since a few weeks ago, some of my add-ons as well as every new add-on I added after that are unavailable at the start of Firefox. I then have to click into the application menu, click on the warning message for that add-on and enable it again. Since this is quite tedious and frustrating, I tried looking online for any info. I tried updating everything, disabling and enabling manually and removed and re-added some if the add-ons that cause issues.

I am loath to set up a fresh profile or reset all add-ons as that would cost a lot of time to configure everything again. In hopes of a solution that avoids that I am asking here now.

After upgrading Firefox, i cannot connect to internet. My internet is working fine, but none of the websites can connect. I restarted Firefox twice. I restarted my laptop (windows11), can you help me? Email removed for privacy

After updating Mozilla Firefox to the latest version, it changed the default language from English (US) to German (DE) although English (US) is currently selected as the default language. It will not change back to English (US)

Hi! I m trying to uninstall firefox in windows 11. The "installed applications" of windows doesn t appear. Then, when using helper.exe does not allow to select "uninstall". Simply reinstall the application. Any suggestion? Thanks

With the last two updates that Mozilla Firefox for desktop sent, I get an error message that will not allow me to open or use Firefox. The error message is "Cannot load XPCOM." I've had to uninstall Firefox and download it again both times to make Firefox work until the next time you send an update, then I have to go through this procedure all over again. What is going wrong? Any help would be greatly appreciated. If this cannot be fixed I will need to find another browser (although it won't be as good as Firefox has been over the years.

I have the same problems as several others. Bought a new computer and cant get download helper to pin to pin to the toolbar. Have tried hitting the puzzle piece and finding the tab after that for extensions but still cant find how to pin it as it does not give me that option.

I guess there was an update to Firefox today because everything about my browser was a mess! >:( I have always had the Honey and Pinterest pin it buttons on my toolbar, and they have worked just fine. Now that this nightmare "update" happened, they don't show anymore, even though they are enabled in my settings and all permissions are checked. I am NOT very techy, so please don't reply with a long technical response that requires me to spend an hour trying to fix it. The buttons showed before, so why not now?! Please help! I've cleared cache and cookies, cleared history, everything I can think of and nothing is working. :'( TIA
