Ondersteuningsforum voor Firefox

I would like to download Firefox 4. I get an error message during download saying it is incompatible with my operating system and that it needs OS X 10.5 or 10.6 but I AM using 10.5.8, so what might be the problem?

When I go to print an email the text comes out too small to read. How do I change the font size. Also, page sometimes moves up and down when I'm typing a reply to an email. Upon viewing before printing the email text, it appears normal font size, but when it prints out the text is too small to read.

Actually, the whole right side of the window is cut off, including the page/window header. This isn't just the websites I visit, it's the whole browser window(s). The word "Settings" is also cut off on the right side.

I have windows XP. Firefox is very slow to open. I noticed 8 versions of Firefox setup exe in the folder "downloads": 3.6.2, 3, 7, 10, 10(2), 12, 13, 14. Can I delete the older versions and keep only the latest Firefox set up 3.6.14 exe. Will it speed up the opening of the browser Mozilla.

I "had" firefox auto update on. After the latest update occurred, most games on www.pogo.com wont play. I sign in to my account, select a game, the game starts loading, then stops at a blank screen.

On my search engine side bar, i always set Google as my search engine, but whenever i start the browser, it automatically turns out to a new search engine, like 'Search the web'..etc

When I enter the Comcast email service the list of emails is extremely small that it cannot be read. I need to enlarge the fonts so that they are readable. I do not have this problem on Internet Explorer. Internet Explorer has an icon to enable font size changes. How do I change font sizes on Firefox?

Up until a few days ago I had no problem with viewing You Tube videos and now I cannot. However, I can still through other browsers. I have updated Flash Adobe; updated Java but to no avail. Help!!

I've had Firefox as my main browser for years. I have always been able to click the 'Open a new tab' plus sign at the right of any open tab and get a new tab. I've also always been able to go to File and select 'New Tab' and gotten one. All of a sudden today, without any updates or anything, I am unable to get a New Tab by any means. It is very frustrating as I do my work in Firefox and need the ability to have multiple tabs in one window instead of having to switch between 7 different windows. Please help.

I love using Firefox, it's by far my favorite browser. But when I opened it this morning, it says I am no longer protected because of the older version I'm using. I want to download the new version but it says that it is incompatible with my computer.  ?? This is the same operating system I've used and it's on the list of compatible OS....mac 10.5.

HELP please! I miss it already!

Has firefox resolved the problem with pogo .I had to download firefox old version so I could play there .Is it ok now to upgrade to the latest version of firefox?

When I started up Firefox Portable on my system from my thumb drive, I got a notice to update the software to a more current version. The software referenced was Firefox, not Firefox Portable. I'm wondering if there is a newer version of the Portable software, or if I can continue to use the one I have.
