Hi Audric,

If the official website of Dominos and Ebay is not loading with proper display, then there are certain fixes you can try which are mentioned below:

Fix 1: Refresh Firefox
If you're having problems with Firefox, refreshing it can help. The refresh feature fixes many issues by restoring Firefox to its default state while saving your essential information like bookmarks, passwords, and open tabs.

All of your Firefox settings and personal information are stored in a profile folder. The refresh feature works by creating a new profile folder for you while saving your important data.
Add-ons which are normally stored inside the Firefox profile folder, such as extensions and themes, will be removed.

1. Click this Refresh Firefox link directly, if you are viewing this page in Firefox.
2. To continue, click Refresh Firefox in the confirmation window that opens.
3. Firefox will close to refresh itself. When finished, a window will list your imported information. Click Finish and Firefox will open.

Fix 2: Clear cookies and cache
Firefox caches websites, which means it saves some files on your machine so that it doesn't have to re-download everything when you visit sites. If a website has updated their code, Firefox may still be using some of the old code along with some of the new, which can make a web page display incorrectly. To fix this, you need to clear the cookies and cache:

1. Click the menu button, choose History and select Clear Recent History....
2. In the Time Range to clear: drop-down, select Everything.
3. Click the arrow next to Details to display the list of items that can be cleared.
4. Select both Cookies and Cache.
5. Click Clear Now.

Now that your cookies and cache are cleared, visit the website again to see if the problem is solved.

Fix 3: Reset minimum font size
Some sites do not display properly with a minimum font size. To reset the minimum font size:

1. Click the menu button, and choose Options.
2. Click to select the Content panel.
3. In the Fonts & Colors section, click Advanced….
4. Change the Minimum font size to None.

Fix 4: Check to see JavaScript is not blocked
You should check whether you have an extension (such as NoScript) or Internet security program (such as a firewall, antivirus, or anti-spyware program) that can block JavaScript.

You can also perform below steps:

1. Click the Tools drop-down menu and select Options.
2. Select the Content section from the options at the top of the
   pop-up page.
3. Check the boxes next to Block pop-up windows, Load images automatically, and Enable JavaScript.
4. Click OK.
5. Refresh your browser by right-clicking anywhere on the page and selecting Reload, or by using the Reload button in the toolbar.

I hope this helps in loading of the websites properly.

Regards,
Lokesh
