Had Firefox update 78 for my Mac, operating sys. OS X El Capitan 10.11.8.. tried to update to 91. After update found out 91 would not work on my OS X. Npw I don't have Firefox and can't find Ver 78? help!

Can someone please help me figure out how to download and install v78 Firefox browser. All current download version options default to v94. I need v78 to ran a Logitech Alert Camera application.

Many thanks,

Nick

I have had this issue before and uninstalling and reinstalling has fixed it in the past. Today when I opened firefox it prompted me to update , which I did without thinking. Subsequently, it stopped working. I have tried: restarting my PC, running in troubleshooting mode( it wouldn't even open when I tried this), uninstalling and reinstalling using the internet installer, uninstalling and reinstalling using the offline installer ( tried on multiple hard drives, so I don't think hardware failure is the issue), installing an older version of fire fox, and installing the 32 bit version instead of the 64 bit version. The attached images show what displays upon trying to launch firefox. nothing loads, not typing an address into the search bar, not clicking on a bookmark, the only UI element that will display is the 3 horizontal line setting menu.

Hi,

I have a fresh installation of my Macbook OS, and a fresh Mozilla Firefox installation. I would like to re-import my old passwords and log ins, but it seems that the new version of the browser doesn't have that option unfortunately. I can see only Import from Other Platforms options, but not import from file or similar.

I have .csv file, but no option of how to import in into my browser.

I would appreciate help on this one. Thank you in advance.

I did not like installing apps from firefox add-ons but loved installing applications from firefox marketplace when it was there back then. It made me feel productive as it was the app store of an OS ,which was also there back then. But why was it discontinued? If there is any reason, please reply and If possible, please try recreating it. Here are the new firefox marketplace icons I suggest which I got from the web archive. Each icon is larger than the previous one. And if possible, please work on firefox OS too.

Hi, The problem I have is that when i download a screenshot in Firefox, left click the download arrow in the top right corner, click on the file, I get a message that says "the app didn't start". Never had the problem in November but seems to have happened after a Firefox update. I have the most current updates for Windows 10 pro 64, Firefox has been removed and reinstalled, Comodo was disabled, Strong VPN was disabled, browser privacy was set to standard, I have set up a separate folder for Firefox downloads and get the same message. I should note that these are all .png files. What app do I need and is it a Windows or Firefox app? Thank you for any help.

Hello,

I followed these install instructions (https://support.mozilla.org/en-US/kb/run-firefox-chromeos) to install Firefox on my new Chromebook but I got this Linux Terminal error message when I attempted the final step of installing Firefox:

flatpak install firefox Looking for matches… error: No remote refs found similar to ‘firefox’

I am a novice and thank you for your help.

Hello Why is it that every time I open Firefox, I get a message asking me to update? If this persists, I may need to use another browser. I keep pressing the "download" button for the upgrade but nothing happens. Could this be the issue? Please help as I do not want to change my browser. What have I done wrong that the upgrade is not happening automatically? Thanks

Firefox recently updated to version 95.0. After updating, Firefox does not connect to the internet. It keeps timing out when trying to connect. All settings remain the same. I cannot communicate/troubleshoot using Firefox because it will not communicate on the internet. Microsoft Edge works fine and communicates.

Is there a way to back out of the version 95.0 and return to version 94.02?

Last time I updated Firefox all menus and settings were lost. How can I avoid that? Yes, I know the answer is "that shouldn't happen" but it did and took my software engineer husband an hour to figure out how to get them back. Would like to skip that step. It's been more than a year since I updated but I'm now getting error messages saying my browser is out of date and website cannot be used without an update. Help!
