The question is a little abstract so let me explain.

Suppose I make a webpage solely for offline use, say an Image Viewer so that users can view their photos full screen.

The user has the option to either select files or drag n drop files https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications

The files are then iteratively stored in IndexedDB.

When the user closes the browser and comes back the next day and opens up the webpage, the images are automatically loaded instead of having the user select the images again.

The problem comes when the user first uploads the images. Some images might have the same name.

Do I have to check if the 'key' already exists in the DB before hand or can I store the file path of the images in the DB as the key?

I installed 18.0 today. I have it set up to open FF search page (about:home) when I open a new tab. This search page no longer functions; I can input search terms, but neither the search button nor enter does anything. It just sits there.

I tried the steps outlined here: https://support.mozilla.org/en-US/questions/934580?esab=a&as=aaq It didn't help. I also tried addons disabled. No go.

I am up to date - it says there are no updates available. But my pogo games will still not load. Per Pogo I uninstalled Java 7 and installed Java 6 Update 38, closed the browser and re-started my computer but most of the games I play daily on Pogo will not load. On some games when I try to chose a room to play in nothing happens - just sits there. Other games let me chose a room but then it says "game loading" forever - never loads. However, with Google Chrome there are no issues. All the games load just fine. So what gives?

I am on 15" MacBook Pro Retina with HDMI to an LCD HD TV. OS X 10.8.2 Firefox 18.0

When I have the Firefox browser on the TV screen, drop down menus appear in miniature on the MacBook screen. I disabled the hardware acceleration and this seemed to work for the first instance of use but then the system reverted to miniature menu on the wrong screen.

Any ideas for curing this gratefully received.

I am trying to implement a suggested solution to Search on home page does not work. To do this I am advised to reset the key - browser.startup.homepage_override.mstone.

I do this and check the value in pref.js and via trouble shooting information. The value has been removed.
I exit FF. Checking pref.js shows value not present in file.
I restart FF and the line has been restored to pref.js (confirmed by troubleshooting info) .

How do I stop this value from being reinstated ?

When I open a new tab, firefox (sometimes) let's me see a window with 9 suggested homepages, I think it's the 9 homepages I use the most. I would really love to have that feature, but unfortunatly I can only see it for half a second, and then it changes to that original New Tab with a Lens and a search bar. What can I do to make it stay?

Ever since I updated firefox 2 days ago it has a problem restarting. When I close the firefox window it closes like it normally does but whenever I try to restart firefox it shows the notification that firefox is still running and I first need to shutdown the previous process before I can start a new one. At last after I manually shutdown the firefox process it will restart again.

Firefox 18.0 works well when I open it on a 32-bit desktop. I can open any website (I use only one tab). But when I shut down Firefox, I get the "Firefox crashed" message. It reloads ok, but I've never had this problem with any Firefox version before. I downloaded another copy of 18.0 and the same thing happened. 18.0 works perfectly on a 64-bit laptop. Both computers are wired to the router. I keep my security, Windows 7, etc. updated.

If I can download 17.x, I'd like to see if it happens there, too It never did before. I would appreciate your suggestions. Thanks.

There needs to be clarification on the Java issues. It's clear that we can disable Java in the java control panel itself and/or via the plug-in link.

However, what about the firefox options menu? Where you click Tools_Options_Content and then you can check or un-check "Enable JavaScript" -- is that safe to be checked/enabled or is that also part of the security concern w/ Java right now?
