If you're having problems with listing, uploading pictures, browsing Ebay or other difficulties here's a list of things to try.
(Updated from countess_vlad's original)
1. Ensure Your Browser is Compatible
Some internet browsers do not work very well with eBay's software. At the time of writing, Safari and Google Chrome can give unpredictable results in some areas of eBay, particularly with forms such as the selling form. If you are having problems in making something work as it should, then try either Firefox or Internet Explorer.
Internet Explorer 8 can have some problems which are solved by using the compatibility button which is to the right of the address bar.
2. Delete Cookies and Temp Files
Internet Explorer 8:
Internet Options -> General tab -> Under Browsing History -> Click Delete -> Tick the boxes alongside Temporary Internet Files, Cookies and History -> Click Delete -> Click OK.
Internet Explorer 7:
Internet Options -> General tab -> Under Browsing History -> Click Delete
In the Cookies section -> Click Delete cookies -> Click Yes to confirm.
In the Temporary Intenet Files section -> Click Delete files -> Click Yes to confirm.
In the History section -> Click Delete history -> Click Yes to confirm.
Internet Options -> General tab -> Under Browsing History -> Click Delete -> Click Delete All -> Click Yes to Confirm -> OK.
Internet Explorer 6:
Tools menu -> Internet Options -> Click Delete Cookies (you might have to wait a minute or two here) -> Click Delete Files -> Check the box Delete all offline content -> Click ok (you might have to wait a minute or two here) -> Click ok.
Tools menu -> Clear Recent History -> Click the Details button -> Tick Cookies, Browsing and Download History & Cache, untick everything else -> Click Clear Now.
(for older systems such as Win98SE only. If still on FF2 with XP or above, upgrade to the latest version)
Tools menu -> Options -> Privacy Tab -> Settings button -> Check cookies & cache, uncheck everything else -> Click OK -> Click Clear Now... -> Ok
Toolbars often cause compatibility issues and can be a source of spyware. If you are still having issues after the above, try removing or disabling any toolbars you are running.
3. Update Java & Flash
Start menu -> Control Panel (may need to select Classic Mode) -> Java -> Update tab -> Update Now button.
Or visit the website below, it will check if you have the correct version and offer an update if not -
Also, go to Add/Remove Programs and uninstall any versions of Java that are older than the current version.
It shows you what your current version is in the browser you are using and what the latest version is. If you need to update then click the Adobe Flash Player Download Center link.
You need different versions of Flash for IE & Firefox, so visit the page in each browser that you use. The page should pick up which browser you're using.
Note: When installing any free software ensure that you watch the install and untick any additional items such as toolbars (Flash at the time of writing tries to install Yahoo Toolbar for example).
4. Check for Updates for Your Operating System
First Save any documents/files/pics etc and close all applications.

Right Click on My Computer -> Properties -> Automatic Updates.
Start Menu -> Settings -> Control Panel -> Automatic Updates

It is better to keep your operating system up to date and have automatic updates set. If you select the 3rd option this will scan for updates but prompt you to download & install.
5. Check for Updates for Your Browser
Internet Explorer 7 & 8:
Check for updates on Microsoft's site.

6. Anti-virus & Anti-spyware
Check for updates of your anti-virus & anti-spyware software. Run full scans for each. If you don't know how to do this, start a new thread with a title along the lines of "Help with updating name of software"
The following links are for safe and free antispyware products which will help keep your system clean if you update and scan with them periodically and also use to clean your system after malware has infected you.
It is advisable to use at least two of these programs to ensure all infections are found. In all cases, download, install and then update before running scans. If installing Spybot, make sure you untick the option during the install to deselect the TeaTimer.
