Many websites may not be totally compatible with any of those web browsers, but that's because their webmasters (the commonly used term for the programmer of a webpage)
neglect to follow WWW Consortium Standards. You should write the webmaster of any website that doesn't follow those standards and let them know that the web is more than just for Windows users, and that following those standards will help their web pages be more accessible. First off, those who can't afford another operating system, can now see their website as viewed from nearly every browser on the planet at Browsershots.org.
A great page on helping webmasters become more crossbrowser compatible is Anybrowser.org. Others include Webstandards.org, and Webmonkey.

Meanwhile if the webmaster doesn't respond, here are links to all the major web browsers for the Mac and tools to make them work more efficiently. In addition to requesting webmasters to make websites more compatible, let the authors of the web browsers know when a website doesn't work. Below the table below are Java updates.
The contact link to the various web browser authors is in the table below next to each web browser:

Wikipedia lists the latest Safari version, and which operating system can use it
Safari 9.0 ships with Mac OS X 10.11, and version 9.1 is available for 10.9, 10.10, and 10.11 through Software updates for the operating systems combined with the the security update, and the Safari update through the App Store. 10.10.4 for instance can't get Safari 9.1, but Mac OS X 10.9.5 and 10.10.5 can, and it must be installed separately from the security update unless you install all the updates for the operating system together including remote desktop and other updates which may not be needed by you. Other browsers such as Chrome and Firefox are not as sensitive to the operating system.

Safari 6.0.5 is part of Mac OS X 10.8.5.
Safari 6.0 ships with Mac OS X 10.8 Mountain Lion.
Safari Safari 6 for Mac OS X 10.7, and Safari 5 for Mac OS X 10.6 are being kept up to date.
Safari 5.1.6 came out with 10.7.4. In 10.7.3 and 10.6.8 it is 5.1.5. Safari 5.1.2 is available in Mac OS X 10.7.2, and 10.6.8 from Apple for 10.6.8 only. Version 5.0.4 is included with 10.6.7. Safari 5.0 is included with 10.6.4, however requires 10.5.8, and 10.6.2 or later on Apple's website. Note, version 5.0.2 has reportedly had issues with some computers slowing downloads of updates. 5.0.3 appears to have fixed the problem for some, as well as issues with the download speed of . Version 4.0.5 could also run on 10.6.2. Version 4.0.4 shipped with Mac OS X 10.6.2. Version 4.0.3 came with 10.6 and 10.6.1. Version 4.0.2 was included with 10.5.8. Safari 3.2.3 is also available for 10.5.7, 10.4.11 (no longer available as English download), Windows XP and Vista (version no longer stored at Apple). Version 3.2.1 was available for 10.5.5. Version 3.0.4 was included with 10.4.11, and 10.5, 10.5.1, and 10.5.2.
Version 3.1 and later include a "Develop menu" in the Safari menu -> Preferences -> Advanced that allows Safari to spoof a website into thinking it is a different web browser. Prior versions (3.0.4 and earlier), read about enabling the Debug menu. If you want to explore the command line via Applications -> Utilities -> Terminal, you can enable the Debug menu that the previously available software Safari Enhancer does offer you a User Agent menuitem to cloak itself as a different web browser (I'm not sure which versions this works on since I haven't tested it on all):
defaults write com.apple.Safari IncludeDebugMenu 1
Additional Safari addons which may improve browser compatibility can be found on Pimp My Safari. Nagarabrowser (original source no longer exists) gives Safari a kiosk mode. With the 10.3.9 update it has been reported that several third party addons such as Saft and Acid Search will need updates. The March 2005 security update fixes Java issues on Safari, and if you applied the 10.3.9 delta update, applying the 10.3.9 combined update will often fix issues. See my Upgrade FAQ for more on how to apply updates without running into issues such as these.
|Version 1.1.1 and later are only available as part of Apple's Mac OS X 10.3. Older versions of Safari are only available in non-English varieties from Apple: Version 1.3.2 is available for 10.3.9. Version 2.0 is current as of Mac OS X 10.4, and 2.0.1 is available for 10.4.2)*, and 2.0.4 is available when you upgrade Mac OS X 10.4 to 10.4.7 through 10.4.10.

|Microsoft Internet Explorer is no longer available for download from Microsoft. A WINE version for Intel Macs offers some I.E. 7 compatibility.||The Mac OS X version 5.2.3 is available from Majorgeeks. There are several stores which carry old Apple operating system disks which also included Internet Explorer for Mac OS X. If installing older operating system disks, be sure to observe the System Specific installation notes. The Mac OS X version of Internet Explorer was last preloaded on Mac OS X 10.3's Install Disk 2 as version 5.2.3. The included Internet Explorer for Mac OS 9 on restore disks and Mac OS 9 installer disks is version 5.0. Remember if installing Mac OS X, only an Archive and Install and Upgrade and Install will let you preserve applications from previous versions of Mac OS X on the hard disk. Otherwise, you'll need to either use the Install Additional Applications from the restore disks, or Charlessoft's Pacifist to extract the files from the installer packages to reretrieve Internet Explorer (if it wasn't backed up elsewhere).

|Waterfox - An updated Firefox clone for Mac OS X 10.5 Intel to 10.7.5, and 10.5 Intel or later. This tip was written on Apple Support Communities: "It's October 2017 now, and I run the current version of Waterfox (55.2.2) on OS X 10.7.5. It's derived from Firefox, but is is less tardy than Firefox. I like that the Reader mode has speech output tied to OS X's voices and that it automatically chooses the correct language as well - if only it wouldn't crash sometimes for some reason... Important for Youtube: If Youtube videos don't play in Waterfox (giving you a playback error message) you will have to deactivate the Multiple Process feature in Waterfox's preference settings."||Contact info|

You can run PC web browsers on the Mac if you use one of these Intel operating systems on the Mac solutions. Note however, any website which requires you use Internet Explorer for Windows is unlikely to be a very secure website, given the number of times such websites have been hacked.
Java version 7 has had a security flaw which is documented on my tip user tip on Apple's Support Communities. Apple explains the latest Java available for Mac OS X 10.4, and 10.5, at Article TS3489.
The latest Java exists for Mac OS X 10.6.8 and 10.7.3 and addresses some of the Flashback trojan issue. For the 10.6.8 download go to DL1516.
Java for 10.7.3 and later is supported by http://www.java.com/
The latest Java for 10.5.8 is http://support.apple.com/kb/DL1359
And for 10.7 go to Oracle's Java page. Apple has a guide to the latest Java updates on their Technote Database. Not all Javas are Mac compatible without Emulation or Virtualization as ActiveX was only developed for Windows, and is not a true Java. Any site that uses ActiveX should be criticized for not using an open standard of Java. Java support may be improved 10.2.3 combo or 10.2.4 through 10.2.6 combo updates, Java update for Mac OS X 10.3 to Java 1.4.1, Java update for 10.3.4 to 1.4.2, Java Update for 10.3.9, Java 2 Platform Standard Edition (J2SE) 5.0 release 1 for Tiger, Software Update search for latest Java updates
The Carbon Java Plugin, and Java Embedding Plugin are both different plugins which can be used to make certain Java sites more accessible in some Mac OS X web browsers. I would be careful not to run both at the same time.
Similarly with Flash, its security has come into question, and my user tip on Apple's Support Communities discusses how and why. . This discussion on Apple Support Communities explains how to install Flash 11.5 on older browsers.
Numerous animations, including some Youtube animations require Flash. Older browsers may be compatible with newer versions of Flash, but possibly not the newest version. Adobe has a Past versions of Flash download page. Also ClicktoFlash allows you to have control over which websites you allow to load Flash.
A similar problem to that which exists for web browsers, is that most e-mail programs don't have complete support for web browser standards. As a result, getting HTML e-mail can be problematic at best. There is an excellent site that discusses the issues of HTML e-mail at Birdhouse.org. Among them there are security, accessibility, and design elements which simply don't render the same way on all e-mails. If you receive HTML e-mails and have no option to receive text, I recommend contacting the company that sends such e-mails and ask for a link to the webpage which has those documents. Attachments are also problematic as my Mac OS X page reference discusses. It is better for any document being transmitted via e-mail that can't be represented by ASCII text to be saved to a website and referred to by a link in an e-mail, than attempts to render information in e-mail which can't be universally read.
