DavyB from the UK asks:
"If I enter an address [www.ebay.co.uk for example] in the address box
and click it does not work. What should I do to fix it. Is it a
glitch that has arisen in Firefox? It does work in Internet
This is a question I get frequently, both with Firefox and Internet Explorer. Fortunately, it has a very simple solution.
A browser-specific problem like this is almost always related to an installed plugin that is interfering with the browser (in this case, Firefox). Disabling all add-ons temporarily is a good start. In Firefox, selecting Help > Restart with add-ons disabled will being with a clean slate.
This doesn't really fix the problem, though. The next step would be to systematically restore each add-on individually until the problem reoccurs which will isolate the plugin that's causing the issue. Once it's isolated, other action can be taken, such as using a developer-suggested workaround or even replacing the plugin with an working alternative.
