During class today, Firefox unexpectedly crashed on my Windows 10 PC after downloading a pdf file from my History teacher. Now, when I try to open Firefox, a transparent box quickly appears before disappearing again, not opening Firefox. I have yet to find a solution that has worked.

Over the last couple of days we are seeing instances of Firefox just disappearing from Windows 10 and just today from a Windows 7 pc. When I say disappears, the desktop shortcut becomes dead, click on it and a prompt to search for firefox.exe comes up. Checking Add / Remove programs shows Firefox to be installed. Checking C:\Program Files\Mozilla Firefox reveals empty folders with the exception of a couple of text files. Trying to reinstall the Firefox app, we are prompted with a message that Firefox.exe can't be found, and there is a button to browse for it. The only solution we have found for this is to copy the C:\Program Files\Mozilla Firefox folder from a working pc, and we just received a call from a user we did this for telling us that it is gone again. Any ideas?

Thanks.....

We have checked for viruses.

Hi there,

I have a brand new Win 10 MS Surface 4 Laptop, and have tried downloading and installing various versions of Firefox:

From the the Windows Store Direct downloads (via MS Edge): Mozilla FF Win 64 Mozilla FF Win 64 MSI Mozilla FF Win 32

I have completely uninstalled and attempted to re-install each in turn. Attempts to open FF through desktop shortcut, Start Menu and Win-R FF.exe all seem to start but only ever get the briefest flash of a blue line along the Taskbar then nothing. Same happens starting Shift-Shortcut.

Nothing shows in Task Manager either after any start method. I'm pretty sure I'm not in 'S Mode' as I've been able to download, install and run WhatsApp Web, but I'm not wholly convinced I've cleared that up fully.

Thanks! E

I am testing FF91esr for deployment later this year. Having a lot of grief with it.

For context; On most of our PCs the profile folder is NOT in the %APPDATA% folder. It lives on a different drive, typically drive F:\

This allows us a lot of freedom to restore a users C:\ drive without messing up the Firefox profile, or losing recent information, for example. We do the same for Thunderbird and several other applications.

The profile.ini file does live in its default location and points to the relavant folder path=F:\Users\<username>\profiles\<profilename> IsRelative=0

We backup a users PC with a comprehensive script which copies the profile.ini and Profiles folder. The group policy is also backed up, and in that policy we have set to use legacy profiles.

When we build a new PC for a user we restore those backups in the hope that the user will take up where they left off. For example, their browser history will be at the point is was when they left the PC.

The whole process is pretty automated. However, with FF91esr I cannot get it to use the folder we backed up. It ignores what's in the profiles.ini file and creates a new profile in the default location, set's it as default and of course sets IsRelative=1.

I tried several combinations of things to try to stop this, but in the end the ONLY way I could get it to use the restored profile was to go to about:profiles, create a new profile, point it to the folder where the restored profile is located, restart using the new browser, then via about:profiles, delete the bogus profile (of course having set the restored profile as default).

I'm not going to sit at 250 PCs doing that. It's crazy.

How can I get FF to use the restored profile folder and stop it endlessly creating new profile folders?

So far I've only tested with clean installs of FF91esr, so this is not an issue with different versions of profiles. But I am concerned over what's going to happen when I update Firefox on a PC...

I sometimes receive notification that Fx can't update automatically and I need to download the update. Twice now, the update has deleted my profile on drive D, and replacing it with a new one on the default C: drive. Settings, options, addons all GONE! I finally had to restore my entire system from a backup. What's going on and how can I prevent it happening again?

Firefox slow to load, 20-30 seconds. Appears is opening more than one instance with a single click. When it does load it sometimes comes up with the last page I had open even tough I closed it out properly. Sometimes get error msg that must close out 2nd Firefox before can start Firefox but saying yes results in the current open window closing. This started yesterday and the latest version of Firefox was automatically installed yesterday? Window 7. Cleared cash. Disabled all add on's etc. No help. Close out Firefox and Task Mngr show no Firefox running. Start Firefox and Task mngr shows four/five Firefox running. This started yesterday and the latest version of Firefox was automatically updated yesterday. Any ideas.

Firefox Not Saving Imported Data from Chrome - MacOS Catalina

Hi All! Need some help for a client please :) iMac 27in (late 2013) Processor = 3.2Ghz Quad Core Intel Core i5 Memory = 8GB DDR3 MacOS Catalina = 10.15.7 1TB HDD Not sure if this is a MacOS thing or a Firefox thing. My client would prefer to use Firefox, currently using Chrome. However - whenever they close Chrome or shutdown / restart the computer, Firefox looses everything and they have to re-import all the data from Chrome. This is happening on a continual basis. It's simply not saving any data / settings that are imported from Chrome.

Thanks!

What is causing the browser to revert back to previous version? The previous version was 85.02. I have uninstalled Firefox and reinstalled v86.0. Eventually, the browser reverts back to the previous version. When I tried to open the browser, the following message appears:

You've launched an older version of Firefox Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for the installation of Firefox.

                                                                               Exit              Create New Profile

I work on computers without admin rights, and i can't install add-ons,

how to make a true portable Firefox without using registry at all

I really don't understand that a free software allows such a blocking, even if chrome doesn't pose any problem with add-ons.

is there a way to lanuch firefox with a option to not use registry or to redirect registry in file or in a not locked custom registry like

hkey_local_machine/software/policies/Mozilla_portable/Firefox

or something like that ?

All of a sudden Firefox has ceased to react when I'm trying to download a file/save a page. When I click Cmd+S or File → Save page as…, nothing happens. When I try to open an upload dialogue, a solid gray window appears, and that's it. Uploading files through drag&drop interface works fine.

The problem seemingly appeared after migrating from a Mac Mini to a Macbook Air (both M1). I've already tried to restart the laptop and refresh Firefox — to no avail.

Is there anything else I could try to do?
