Ok, No problem,Just keep your mind cool and read carefully and try steps: You could try to hide or collapse that bottom margin with code in userContent.css Maybe also hide the top margin to get more space for the thumbnails.

Add code to the userContent.css file below the default @namespace line.

   http://kb.mozillazine.org/userContent.css 

@-moz-document url(about:newtab){

1. newtab-margin-top, #newtab-margin-bottom { display:none!important; }

}

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

   http://kb.mozillazine.org/Editing_configuration 

   Create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
   Use a plain text editor like Notepad to create a (new) userContent.css file in the chrome folder (file name is case sensitive)
   Paste the code in the userContent.css file in the editor window
   Make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userContent.css.
   Otherwise Windows may add a hidden .txt file extension and you end up with a not working userContent.css.txt file 

Done! If works please click on solution or if not, mail me. Have a nice day! Thanks.

You may have zoomed the page(s) by accident. Reset the page zoom on pages that cause problems.

• View > Zoom > Reset (Ctrl/Command+0 (zero))

• http://kb.mozillazine.org/Zoom_text_of_web_pages

If you have made changes to Advanced font settings like increasing the minimum/default font size then try the default minimum setting "none" and the default font size 16 in case the current setting is causing problems.

• Edit > Preferences > Content : Fonts & Colors > Advanced > Minimum Font Size (none)

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

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

It is better not to increase the minimum font size, but to use an extension to set the default page zoom to prevent issues with text not being displayed properly.

firefox just started to do this for my document where I have to fill out forms. The right side of the documents seem to be cut off. It does not matter if I increase or decrease the sisize of the document, Using chrome or going to my pc using windows 8.1 I can see the documents correctly to fill out. Firefox for linux with the new updates and going to yahoo has cause alot of problems. Hopefully you have a fix or a better update. I am using your most recent 34
