New Version Of Firefox For Mac
Firefox was created by Dave Hyatt and Blake Ross as an experimental branch of the Mozilla browser, first released as Firefox 1.0 on November 9, 2004. Starting with version 5.0, a rapid release cycle was put into effect, resulting in a new major version release every six weeks.This was gradually accelerated further in late 2019, so that new major releases occur on four-week cycles starting in 2020. Sometimes, the latest version of an app may cause problems or not even work. While the developer is fixing the problem, try using an older version. If you need the previous version of Firefox, check out the app's version history which includes all versions available to download. Download prior versions of Firefox for Mac.
Users on 64-bit Windows who download Firefox can get our 64-bit version by default. That means you get a more secure version of Firefox, one that also crashes a whole lot less. How much less? In our tests so far, 64-bit Firefox reduced crashes by 39% on machines with 4GB of RAM or more.
What’s the difference between 32-bit and 64-bit?
Here’s the key thing to know: 64-bit applications can access more memory and are less likely to crash than 32-bit applications. Also, with the jump from 32 to 64 bits, a security feature called Address Space Layout Randomization (ASLR) works better to protect you from attackers. Linux and macOS users, fret not, you already enjoy a Firefox that’s optimized for 64-bit.
How do you get 64-bit Firefox?
If you’re running 64-bit Windows (here’s how to check), your Firefox may already be 64-bit. Check your Firefox version (in the “About Firefox” window) and look for “(32-bit)” or “(64-bit)” after the version number:
- If you see “(32-bit)” and you are running Firefox 56.0 or older, updating to the latest Firefox version should automatically upgrade you to 64-bit.
- If you see “(32-bit)” and are running Firefox 56.0.1 or newer, then your computer may not meet the minimum memory requirement for 64-bit (3 GB RAM or more). You can still manually install 64-bit Firefox, if you choose.

Installing
Please note that installing a new version of Firefox will overwrite your existing installation of Firefox. You won’t lose any of your bookmarks or browsing history, but some of your extensions and other add-ons might not work until updates for them are made available.
Uninstalling
You can remove Firefox with the Add/Remove Programs utility on Windows, by moving the Firefox application to the Trash on Mac OS X, or by deleting the containing folder on Linux.
By default, removing Firefox won’t remove your bookmarks, web browsing history, extensions or other add-ons. This data is stored in your profile folder, which can be found by going to the Help menu and selecting Troubleshooting Information... The button next to the Profile Directory line in Application Basics will open your profile directory in your system's file explorer.
Please note that if you keep your profile, any version of Firefox that you install after removing Firefox will continue to use the bookmarks, web browsing history, add-ons, and other data from this profile folder.
Add-ons and Themes
You can get Add-ons and Themes by opening the Add-ons Manager, or by visiting the Add-ons Web site. Add-ons installed with previous versions of Firefox may not yet have been updated by their authors to work with this Firefox. If you wish to help test Add-ons, please install the Add-on Compatibility Reporter - your favorite Add-on author will appreciate it!
Known Issues
This list covers some of the known problems with Firefox which will be resolved in future versions:
- The Web Developer menu includes a new 'Inspect' option. This is an early version of a developer tool that has already evolved substantially. If you're a web developer, we recommend you download Firefox Aurora and try out the improved version of this tool.
- Users of the Twitter search plugin may see Twitter appear in the search provider list multiple times (see bug 690658)
- Choosing the 'Pop out' menu item while watching fullscreen YouTube videos may cause Firefox to hang (see bug 675645)
- Roundcube, webmail software used by many hosting companies, incorrectly displays an ellipses in place of long email titles. The Roundcube team has been notified of the issue (see bug 680610)
- Arabic text on BBC.co.uk does not display correctly. The BBC has been notified of the issue (see bug 674335)
- Firefox will now display a corrupted content error when it detects certain types of misconfigured servers. This is not a Firefox issue, please contact the website owner (see bug 681140)
- For some users, scrolling in the main GMail window will be slower than usual (see bug 579260)
- If you try to start Firefox using a locked profile, it will crash (see bug 573369)
- Some users of Adobe Reader X have experienced instability when viewing PDF documents in the browser. Uninstalling and reinstalling Adobe Reader X has been determined to resolve the issue (see bug 640901)
- Some ALPS touchpad drivers break scrolling in Firefox. A workaround has been identified (see bug 605357)
- For some users, the preference dialog is not shown and a rendering error (in the form of a white square) is shown instead. This is caused an add-on incorrectly setting Firefox preferences (see bug 641288)
- Users running Mac OS X 10.7 may see a crash when the file chooser dialog is shown. Apple has been notified of the issue (see bug 670842)
- Users running Mac OS X 10.7 are no longer able to use gestures to navigate. This is due to underlying operating system changes and is fixed by Mac OS X 10.7.2 (see bug 668953)
- This version of Firefox will not work on Macintosh hardware with Power PC CPUs (see bug 587799)
- The video control buttons may not work when viewing QuickTime videos with libtotem (see bug 625036)

Troubleshooting
- Poorly designed or incompatible extensions can cause problems with your browser, including make it crash, slow down page display, etc. If you encounter strange problems relating to parts of the browser no longer working, the browser not starting, windows with strange or distorted appearance, degraded performance, etc, you may be suffering from Extension or Theme trouble. Restart the browser in Safe Mode. On Windows, start using the 'Safe Mode' shortcut created in your Start menu or by running
firefox.exe -safe-mode. On Linux, start with./firefox -safe-modeand on Mac OS X, run:
When started in Safe Mode all extensions are disabled and the Default theme is used. Disable the Extension/Theme that is causing trouble and then start normally.cd /Applications/Firefox.app/Contents/MacOS/
./firefox-bin -safe-mode - If you uninstall an extension that is installed with your user profile (i.e. you installed it from a Web page) and then wish to install it for all user profiles using the -install-global-extension command line flag, you must restart the browser once to cleanse the profile extensions datasource of traces of that extension before installing with the switch. If you do not do this you may end up with a jammed entry in the Extensions list and will be unable to install the extension globally.
- If you encounter strange problems relating to bookmarks, downloads, window placement, toolbars, history, or other settings, it is recommended that you try creating a new profile and attempting to reproduce the problem before filing bugs. Create a new profile by running Firefox with the -P command line argument, choose the 'Manage Profiles' button and then choose 'Create Profile..'. Migrate your settings files (Bookmarks, Saved Passwords, etc) over one by one, checking each time to see if the problems resurface. If you do find a particular profile data file is causing a problem, file a bug and attach the file.
