You can try these steps in case of issues with web pages:

Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Hold down the Shift key and left-click the Reload button
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (Mac)

Clear the cache and cookies only from websites that cause problems.

"Clear the Cache":

• Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

• Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window.

still not working here are images ill show you its only one window that opens up earlier it wasnot like that

Note that some images may actually be a font that is downloaded from the server via an @font-face CSS rule.

Make sure that you allow pages to choose their own fonts.

• Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"

Also make sure that the gfx.downloadable_fonts.enabled pref is set to true on the about:config page.
You can open the about:config page via the location bar.

I'm assuming it's the same if you visit in another browser, such as Internet Explorer?

Where a link opens mostly depends on how the site set up its links. Normally links open in the same tab. However, a site can direct the link somewhere else in one of two ways:

• target attribute
• window.open() script command

In either case, the site can specify a completely new window or to re-use an existing window.

If you want to prevent the links from re-using the same window, even if the site is set up that way, try using right-click > Open in a New Window.

If you want to automatically force all links to open in a new window, you probably would need an add-on of some kind, either with an extension (from the add-ons site) or a custom-written user script.

Have you raised this issue with the site or with the community? It might be a mistake on their part. Or maybe they have some social dynamic reason behind it....
