Firefox is made by Mozilla, the non-profit champions of a healthy internet. Mozilla also tackles issues like privacy, misinformation and trolling by investing in fellowships, campaigns and new technologies designed to make the internet healthier. Mac users interested in Firefox 10.5.8 generally download: Firefox 62.0 Free Firefox is one of the most popular web browsers on the market, providing numerous helpful features and quick speed to millions of users worldwide. In Firefox's relentless battle to take on the impregnable Chrome, they've hit a huge milestone with version 57 of their browser. The beta for it is out now for download and includes the new Servo engine whose performance couldn't be more heartening: Firefox is now twice as fast as it was a year ago.
Sometime in 2012, Adobe Flash asked me to update it. I tried, but it didn't work because my browsers (firefox and chrome) didn't support the newest flash. I tried to update my browsers, but neither firefox nor chrome supports mac os 10.5.8 anymore. Safari keeps telling me to update flash too. I know that using an older version of flash can be a security hazard, so I really want to update.
My question: Are there any browsers (perhaps a firefox variant) I can use more safely now than the browsers that shipped with 10.5.8?
Firefox 64.0 - Fast, safe Web browser. Download the latest versions of the best Mac apps at safe and trusted MacUpdate Download, install, or update Firefox for Mac from MacUpdate. Mozilla Firefox is the greatest free and open source web browser in the world published by Mozilla Foundation. Mozilla Firefox for Mac 10.5 8 free download the latest version and install it on your Mac operating system for online browsing. I still am using a Power Mac G-4 1.25 dual using OS 10.5.8 on a daily basis for some work using the internet. I can no longer upgrade Safari, Firefox or Chrome.
bmike♦You should try opera Opera 12 download it fast and works well.
Caveat: Opera only works on Macs with Intel-based processors. If you have a PowerPC chip (G5), good luck. Opera 12 won't work.
For the impatient:
You have two possibilities:
PowerPC-based Mac: TenFourFox and no Flash.
Intel-based Mac: Opera (thanks to Cybermatatu for this one!) with older Flash 10.3 (beware, Flash 10.3 is an archived version and is no longer supported nor updated with security fixes by Adobe).

Long version:
If you use an Intel processor you can use Opera:
Opera 12
OS X Leopard (10.5), or greater: 32-bit and 64-bit Intel systems supported
Opera supports Flash Player plug-in.
If you use a PowerPC processor you may want to try TenFourFox. TenFourFox seems to be actively developed (version 17.0.3 was released Feb 16 2013). TenFourFox supports add-ons, but not plugins, that is, you can't use Flash at all.
Please notice that Flash Player 11 only supports 10.6 and newer. You can still download version 10.3 for 10.5 Intel (beware, Flash 10.3 is an archived version and is no longer supported nor updated with security fixes by Adobe).
As for other browsers: Games download for mac.
Firefoxno longer supports PowerPC processors (PowerBook, PowerMac):
Firefox 3.6.28 is the last version of Firefox that works with Mac OS X 10.4 (Tiger) or with Mac OS X 10.5 (Leopard) on a computer with a PowerPC processor.
Firefox 16 is the latest version that supports Leopard on Intel-based Macs as Firefox 17 requires 10.6 or newer.
Apple no longer releases Safari updates for Mac OS X 10.5 (as stated here).
Chromedoesn't support Leopard, either:
Google Chrome on Mac OS X 10.5 (Leopard) will stop receiving any updates following Chrome 21.
Additionally, I find that when I swipe other to the next week it will sometimes ship months or years ahead for seemingly no reason. Google calendar download for mac. You should be able to have the option to select the cut off date or have them running indefinitely, like you can with “Events.” It’s almost better to set your Goals as Events because Events actually works.
I have had some success in a Flash-less world by using Safari, and enabling the Develop menu. Then when I get to a page that requires Flash, I can set the User Agent to report as an iPad and I will get videos streamed in a QuickTime player rather than Flash-based.
beroeI really like the following 2 browsers. They work even on 10.4.11
nohillside♦SeaMonkey. Still works with my old Salad bowl PPC iMac (1 GHz, 768 MB RAM), and supports flash.
M KThe build requirements for firefox indicate that it should build on your setup. Might be worth a try.
Anyway going without flash is definetly the future.
bdecafbdecafGoogle Chrome v15 still works on Intel Leopard 10.5.8,IF, you can find a copy.PS. I'm using it now.
I'm using iCab 5.1.1, it's working where Firefox won't.
grg♦Tenfourfox fpr4 is the latest Tenfourfox version for your PowerPC MAC's running Mac OS 10.5.8.
