Jeff and .NET

On my machine, Firefox stores its bookmarks in C:\Documents and Settings\$user\Application Data\Mozilla\Firefox\Profiles\default.bnt\bookmarks.html

The bookmark and all your profile is stored as default under C:\Documents and Settings\YourUserName\Application Data\Mozilla\Firefox\Profiles\

Firefox bookmarks are in C:\Documents and Settings\USERNAME\Application Data\Mozilla\Firefox\Profiles\PROFILENAME\bookmarks.html. If you backup, you might want to just take the entire Profiles folder, so history etc are also saved.

Now you've using firefox, I highly recommend both the Adblock extension, and mouse gestures extensions. Both of these can be obtained with the "Get More Extensions" link in Tools->Extensions.

Welcome to modern, crapware free browsing!

[SystemVolume]:\Documents and Settings\[username]\Application Data\Mozilla\Firefox\Profiles\default.[3 random characters]\bookmarks.html

C:\Documents and Settings\<<USER NAME>>\Application Data\Mozilla\Firefox\Profiles\default.9wo\bookmarks.html

I am not totally sure about the bookmarks storage but there is a bookmarks.html and bookmarks.bak in C:\Documents and Settings\[Username]\Application Data\Mozilla\Firefox\Profiles\default.29h\

on my computer.

I don't think the browser wars are about hating MS nearly as much as about hating the time since the last good functional progress in IE. Web developers have to continuously make the choice between
1. making 2 (or more) versions of sites like when netscape pushed their proprietary tags onto the web world
2. write for the W3C standard, assuming that IE will one day make changes to support more of the W3C standard
3. write for IE, assume MS will never fix their W3C support

I don't like choices 1 or 3, so I split the difference between 1 & 2.

Tabbed browsing, etc, can be using with IE via programs like Maxthon, but for the most part, when you say "better browser", IE is not going to be at the top of the list, not for political or emotional reasons, but because it is the standard-bearer of 1999, the highwater mark 5 years ago, and (until the pop-up blocker in SP2), there has been no progress since then.

Try looking in:
C:\Documents and Settings\%username%\Application Data\Mozilla\Firefox\Profiles\%profile name%\bookmarks.html

You can also backup your bookmarks easily by going to Bookmarks > Manage Bookmarks > File > Export

I've been using Firefox since .8 and it only gets better and better with each release. I hope you enjoy your experience.

Bookmarks are stored in the "bookmarks.html" file found in your Firefox profile directory (%homepath%\Application Data\Mozilla\Firefox\Profiles\{random dir}\)

No need to bother with where the bookmarks are at all. Just go to the Bookmark Manager (Bookmarks menu) and select File:Export to create an HTML file that can be imported again in the future if needed.

I'm not going to do that every day to have it backed up automatically. What kind of sense would that make?
