Firefox-Hilfeforum

Hardware: iMac 5K, 27-inch, 2017 macOS: Ventura 13.2 Firefox: 109.0.dmg File Type: Disk Image

For an unknown reason my Firefox browser locked up in the middle of a session. A full system re-start failed to fix the problem – all other software Apple Safari, Adobe Lightroom & Photoshop and Microsoft Office etc. continue to work as normal. Both Bitdefender and Malwarebytes full system scans have failed to identify any security issues.

To remove any possibility there was a macOS issue I successfully recovered the operating system from the mac in Recovery mode.

As the Firefox app would still not respond to the normal app opening process I removed the failed app from the mac “Applications” folder using the AppCleaner app and downloaded a new Firefox app file from the Mozilla Firefox site. I then dragged the downloaded file to the mac “Applications” folder and while holding the control key Ejected “Firefox” from the menu - the “Firefox” named disk icon on the mac screen and showing in the Finder “Locations” disappeared. Following this I successfully dragged Firefox from the “Applications” folder to the dock.

When the Firefox icon in the dock or in the Applications folder are selected the error message appears: The application “Firefox.app” can’t be opened. Repeated deletion of the Firefox app from the mac, restarting the mac, re-downloading the Mozilla Firefox app etc. etc. has resulted in the same failure. In the interim I am using Safari for the web but want to resume using Firefox asap due to Safari’s limitations.

Am I missing something in the Firefox installation procedure or there is an unrecognised security bug in the system? This is the first time I have had any issue arise with a Firefox installation process on either Windows or Apple systems.

Grateful for any advice.

The update Firefox 100.0.1 ( or 2 ) has a bug: Firefox doesn't "see" the Fritz!Powerline ( LAN over Powerline adaptors ) and thus I can't enter the Fritz!Box. Even typing the IP address of the Fritz!Box doesn't help, because there is "no connecting" beyond the PC. The hardware works, so I can send and receive emails, but I can't access the internet via the firfox browser. Stepping back to 99.0.1, I had to "create a new profile" and all my previous ( before the update to 100.0.1 ) settings were lost, all bookmarks vanished ... I am rather angry, you know? This mail I'm sending via my notebook, as I this connects via 100 Mbit Lan network from an other room and as I had to "register" just to be able to complain ...

The bar that contained those items disappeared in Firefox after the update to 110 I believe. I don't know how to get it back, I've searched settings. The bookmarks and all the data appear to still be there. It's been there since, I think, version .9 something. I updated to windows 10 from windows 7 about 3 months back. I noticed the change immediately. I don't even know what the bar is called. I still have my windows 7 machine since I am still trying to resolve problem with windows 10 and I'm even thinking of going back to window 7. It did the update to 109 without a problem.

HELP!!

It is probably something simple by windows is more a game machine to me. I learned computers on a GE-645 to give you an idea of how old I am.

Thanks

I was using Firefox and Owl (the addon).

I just upgraded to Fedora 36. I treid installing Owl and an alternative called "Dark Reader" and both cause a message stating they are corrupted.

I enabled dark mode in the browser. Google immediately changed to a dark background which I can more easily see. This site ignores the setting and is forcing me to work with very limited ivsion

I can barely make out the UI. I found what might be a solution at https://support.mozilla.org/en-US/questions/1356233 but after hours trying to read it I gave up and am wirting here.

It is very frustrating that other sites respond to firefox settings and your support site does not.

Firefox stopped openng, tried to reinstall, no response (see the screenshot) I also use Tor Browser (never any problems) and Chrome (when absolutely necessary, like when Firefox failed to connect to an external email server and for sending queries like this one because Firefox does not work and will not reinstall. )

I got an email to update to version 100, and downloaded and installed, but now I have no bookmarks or anything else, just a blank version. Please help me! Thankyou!!

My HP Omen has 2 hard drives. Originally, Firefox was installed on the C: drive and working perfectly. In order to clear up space, I tried to use the Windows Move feature to move the program from the C: drive to the secondary (and larger) E: drive. Since then, Firefox won't work aside from opening a Firefox window. It will load no pages, settings, etc.

I've tried uninstalling Firefox from both the C: and E: drives. Searched for any remaining files and deleted them. Deleted Old Firefox Data folders. I've reinstalled Firefox, without the option of where to install it, but it still fails to work at all. I get an error message regarding a missing file, VCRUNTIME140_1.dll. I've searched for the file and it's NOT missing. It is in both the Firefox folder and the Windows/Systems32 folder.

I've searched for data in the Users folders that might relate to Firefox but NOTHING seems to work that will allow Firefox to work again. I've tried putting Firefox in Troubleshooting Mode but it won't restart as it says it needs to. It just won't work!

If anyone can just tell me how to COMPLETELY remove Firefox from both hard drives so that I can just do a clean, new Firefox install, that would be preferable. I know how to import bookmarks from Chrome.

If anyone can offer some help for someone who isn't great with computers, I would greatly appreciate it. If you need any other information, please don't hesitate to ask.

Hi,

Firefox updated to 101.0.1 and I miss all addons and my customized toolbar! During update I saw it created an "Old Firefox data" folder on my Desktop.

How to bring back the missing parts?

Thx!

Hi,

To get myself off MS Edge (as its Chromium based), I've come back to FF. But after I tried installing firefox standard and even the Extended Support Release I can not run it for the first time - I get this error

Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I've followed the advice in the help pages, but it hasnt fixed the issue

https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

The same happens when I run

firefox -p

The firefox App Data folder contains no profile file at all....

I've tried uininstalling and wiping all files, and I wanted to try an old versions BUT the link on the page is dead

https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/ - Gives me 404

Do I have some service not running that this relies on ?

I'd like to import my Seamonkey profile data to Firefox, but Firefox doesn't recognize Seamonkey or its data. How can I do this? I'd like to keep my Firefox data synced to Seamonkey, and maybe synced the other way too. And I'd like Thunderbird to be able to sync to the Seamonkey email data too, for what it's worth. I thought the importing of data when Firefox starts would take care of importing SM data but it doesn't. Are there any commandline options for running Firefox that would get the importing done? I sure don't want to mess around with a huge html bookmarks file and there's other data in Seamonkey besides bookmarks that should be imported too. Help!

1. How to install and run Firefox browser in ubuntu Core 22? As My experiment Firefox has the snap package. But it has the dependency its works in Ubuntu 22 Desktop Edition.

I need the support/guidance to install and run Firefox in Ubuntu Core 22.

I have just downloaded firefox from chrome and cannot install it. I have tried the usually uninstall reinstall and restarting my computer but cannot fix it. I have had this issue with other browsers in the past eg opera and brave but gave up on them, however, I really want to switch to firefox so would appreciate your help. For some reason it seems chrome is the only browser I can even open on my laptop (windows 11). Do you know a fix?

I have Firefox installed and set as my default browser and yet my Registry shows the following: Open with Application Issue "C:\Program Files\Internet Explorer\iexplore.exe" %1 HKCR\ftp\shell\open Open with Application Issue "C:\Program Files\Internet Explorer\iexplore.exe" %1 HKCR\htmlfile\shell\open Open with Application Issue "%ProgramFiles%\Internet Explorer\iexplore.exe" -nohome HKCR\VisioViewer.Viewer\shell\open

Since Firefox is set as my default browser I would have expected to see Firefox here in these registry entries as my default browser in lieu of Internet Explorer. However, if I delete those Registry entries, it then breaks any embedded links in MS Programs such as Outlook mail and Excel. I have I.E as non-active (i.e. unchecked in Programs) but the system still seems to rely on I.E for opening any embedded links. Any suggestions as to how to fix this problem would be appreciated.

My Windows 10 computer died. I bought a new Windows 11 laptop and a device to connect my old hdd to the new laptop as an external device to retrieve my data. I’ve spent two days trying to migrate the old profile both the whole folder and selected parts and have had nothing but frustration. Any guidance would be hugely appreciated. I only really care about passwords and bookmarks. Locations and file names seem to not be anywhere the same on the two hdd’s.

Firefox 109 is horrible and I am trying to revert to 108. I have the "Old Firefox Data" file, but have no idea how to get ALL that info back into 108. I am so very upset and frustrated right now! So much wasted time. I cannot believe Mozilla did this to us with no warning!!!!!!!! I have seen some articles on how to get the info back, but I don't really understand them. I am relatively computer-savvy, but I definitely do not understand how all this works. Some "Firefox for Dummies" at this point would be greatly appreciated. I am on a PC using Windows 10 professional 64-bit with automatic updates so it's current.

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

Good afternoon. I just made a clean install of Ubuntu 22.04 in my system. I use Firefox, to navigate, study and download diverse things, including work files. When I tried to download those files in my google drive, it shows me the folder which I will use, everything right, but when I hit "Save", nothing happens. Do you know which is the problem? I can access drive from "files" from Ubuntu without problem, upload and download files... Thanks in advance.
