I am trying to run the latest version of FF on OS X 10.8.4 and I am having some trouble getting the program to open after installation. After the initial installation the browser opened after I was prompted to set up a user profile and I was able to use it. But after I closed FF the only way I can open it again is if I open up the profile manager though terminal (using "/Applications/Firefox.app/Contents/MacOS/firefox-bin -p") create a new profile and click the "start firefox" button. If I try to click the FF icon in my dock it just bounces once and does nothing.
I would start over by trashing Firefox and then downloading and installing a fresh copy. Before running the dmg file, make sure to read How to download and install Firefox on Mac for installation details.
For an up-to-date browser for older Macs, try Chromium Legacy. You may need to use this direct link to download Chromium Updater; no other browser for OS X 10.7-10.8 is able to display GitHub correctly. When opened, Chromium Updater will appear as an icon on the right side of the menu bar. Click it, then select a stable version of Chromium Legacy to download. Once the new copy of Chromium Legacy is downloaded, drag it to the Applications folder. You can keep Chromium Updater and use it to update the installed copy of Chromium Legacy.To enable Google sync in Chromium Legacy, quit the browser, then enter the following command in Terminal (it is one long line):open -a /Applications/Chromium.app --args "--oauth2-client-id=77185425430.apps.googleusercontent.com --oauth2-client-secret=OTJgUOQcT7lO7GsGZq2G4IlT"Chromium Legacy will open; log into your Google account. You will not need to run the command again unless you log out.
Final version for OS X 10.8 Mountain Lion: 71.0p2 (2020-09-15)IMPORTANT NOTE ABOUT UPDATING TO v71: A new Firefox profile will be created when you update from earlier versions to version 71.0. To restore your previous data, type "about:profiles" in the address bar, then find your previous profile (if you can't tell which, try each one) and set it as default. Then, restart Firefox Legacy. I apologize for the inconvenience; the cause of this issue is not known.
On August 2, 2016, Firefox 48.0 was released. It is scheduled to be replaced by Firefox 49.0 on September 13, 2016. At that point, Mac users using OS X 10.6 Snow Leopard, 10.7 Lion, and 10.8 Mountain Lion will be left behind by the current versions of Firefox. It will be a sad day, as Firefox is the last major browser to support Mac OS X 10.6 through 10.8.

I can find numerous packages saying, for example "OS X Lion 10.7.2 Build XXXXX", but all of them seem to updates and are relatively small in size (~ 700 MB). I can't seem to find any image that would allow me to install a fresh 10.7 or 10.8 inside a new VM.
Hello. I am a Korg NanoPad2 owner and used the serial number included with the NanoPad to download the EZDrummer Lite disk image. (I used Firefox 34.0.5 to download the package.) I have installed and authorized EZDrummer Lite and Toontrack Solo from their respective installers in the package.
There is a third installer on the disk image, the EZX Cocktail installer, that will not launch on my computer. I am using a MacBook Pro with an Intel Core i7 processor and running OS 10.8.5. The error message that I get says:
All old and new versions of Mac OS X 10.7 (Lion) (Intel) Chrome editions are available for download from legacy sources. If you are unable to find Mac OS X 10.7 (Lion) (Intel) versions of Chrome below, narrow down your search for the specific platform or app through below links. Apps are listed in chronological order from the release date with latest versions appears on top of the list.
This article provides instructions on installing and downloading the Blackboard Collaborate Launcher. The launcher offers Mac OS X 10.8.4 and later users an easy way to join web conferencing sessions and play recordings by using a known and stable version of Java that is bundled within the launcher itself.Note: Use either Chrome or Safari to download the launcher and launch sessions and recordings. Firefox is currently not supported.How to Resolve/Troubleshoot:
Downloaded the latest version of firefox. When it was opened and it went through the verification process then to move firefox folder into applications for use we received a notice where the firefox logo had a circle with a line through it (indicating to us that is would not function) then an arrow pointing to the application folder. The firefox version downloaded and opened Firefox 91.8 Oesr.dmg
I have found both Safari and Firefox use a very high amount of CPU during downloads (>200% CPU usage), can anyone explain as to why this happens? It occurred both before and after a complete system reinstall. It also uses the same amount of CPU despite download speed. I am using Mac OS 10.8.
I only came across this question today and I hope this is not too late an answer, but the short answers are yes (to your first question "I have found both Safari and Firefox use a very high amount of CPU during downloads (>200% CPU usage), can anyone explain as to why this happens?") and yes (to your comment question "Does a higher then 100% percentage mean it is using multiple cores for that process?").
The short explanation is that your Mac contains a multi-core processor - I'm guessing a minimum of 2 given that you are running OS X 10.8 - which supports hyperthreading, and this means that each physical core (a physical CPU in itself) presents multiple "logical" cores to OS X which it treats as independent logical CPUs. A process can use up to 100% of each logical core, so n logical cores means a maximum of n x 100% CPU usage per process. Hence your Activity Monitor (like Task Manager in Windows) showing CPU usage bars for each of these logical cores (as long as they are
It is impossible to see a >100% CPU usage for a process in a single-core CPU system, unless the reporting tool you are using is faulty. Firefox probably spawns a thread for each download (if you have multiple simultaneous downloads), in addition to a number of other threads for tabs, rendering etc. and other stuff going on, and your reading of 157% for the process clearly means some of these threads were being run on at least two different logical cores at the same time. A reading of 296% would indicate at least three cores being used etc. The CPU usage for a process on a multi-core processor / multi-threaded OS system is an aggregate of the CPU usages for all the threads running inside that process.
If you have a version of OS X that is older than 10.6 you will need to pay to upgrade to Mountain Lion (10.8) first because it is only versions later than 10.8 that are free. You can buy 10.7 or 10.8 at the Apple Store here.
If you want to work with a version of OSX older than Mavericks (e.g. 10.8 Mountain Lion) then you can download an older version of DiskMaker X from their website which works with the older installers.
i have been trying for ages to update my mac book from 10.7.5 can i download this update and get it to work? it is really frustrating me. if there are other means or links, please i would love to be in on the info. thanks.
In most cases, the downloaded dmg file is actually corrupt or had an error downloading. If possible, try downloading the dmg again, turning off any download assistant plug-ins you may have. You can try downloading the file in a different browser as well. Or if you don't need to be logged in to the site to download the file and you want to be fancy, you can try curl -O url in Terminal to download the file. (There's an example of that in my screenshot below.) 2b1af7f3a8
