In Firefox 3.0 there are many ways to add bookmarks:
1. ctrl+d
2. menu Bookmark | Bookmark this page
3. single click on Star
4. double click on Star
etc

None of them are extremely simple. I got very unpleasant surprise with Firefox new user. Just to tell him how to save bookmarks... Very simple think to do but so complicated.

I use my laptop WIFI at many hotels and on many airlines/buses/trains yearly.

Upon first use many of these APs subvert the resolution of the URL (without saving it) that you want to go to, and redirect you to their authentication site which makes you agree to a EULA before access is granted.

Problem is, if i start firefox with 20 tabs open, all 20 get subverted and i lose their addresses.

I have lost hours of research this way.

It should be easy to use thunderbird/firefox autoconfig system (http://mit.edu/~firefox/www/maintainers/autoconfig.html). The problem now is that (thunderbird example) "general.config.filename" preference (which you can set in "/etc/thunderbird/pref/thunderbird.js") is filename path relative to the root of the thunderbird binary directory (for example "thunderbird.cfg"). And this directory (/usr/lib/thunderbird-A.B.C) is changed after every thunderbird upgrade in ubuntu. So, after upgdrade I have to copy/recreate my thunderbird.cfg in new directory.
My workaround is to create and edit /etc/thunderbird/thunderbird.cfg and create symlink to it in /usr/lib/thunderbird-A.B.C directory. To automate it after upgrades I created /etc/apt/99thunderbird containing:
DPkg::Post-Invoke "for i in `ls -d /usr/lib/thunderbird-* | grep -v thunderbird-addons`; do [ ! -e $i/thunderbird.cfg ] && ln -s /etc/thunderbird/thunderbird.cfg $i/thunderbird.cfg; done";
Workaround works well, but using DPkg::Post-Invoke is realy nasty way.
I think automatic customization of thunderbird/firefox should be convenient in large environments.

After Firefox and some other browsers have been stopped (e.g. by crash or power failure), there is an option on the first restart afterwards, to restore the previous session.

Though the user may wish to restore the previous session, they may not be wanting to do that at the time they have opened the browser again - they may want to get on with newly important tasks.

It would be handy to have a few other options in this window;

1) Save the session for later.
2) Save the addresses to a folder in favourites

plus
3) Restore session, but do not wait more than "x" seconds for websites that require certificates, or have failed downloads.

In the case where there have been multiple windows each with multiple tabs, the session can take so long to restore, that some pages time out. This can leave the page non-recoverable. The page becomes recoverable as soon as its address has appeared in the address line. For large restore sessions, it is necessary to manually switch from window to window and "stop" each page as soon as an address has appeared, so that there is enough bandwidth for other pages to download. Only after all the addresses have appeared, is it safe to go back and individually re-fresh each page to get the full content (also able to close the pages which you are no-longer interested in)

4a) It would be handy to have a mode of session restore, that automatically did this process, and
4b) maybe has the option to either automatically or manually refresh the pages.

5) It might be helpful to have a "selective restore", which does not force the user to open "all" the web sites. They could be presented with a list (like the history/folders side bar list), and can click on that to delete,move, open, save to favourites. They would not even have to go to the web page again (saving bandwidth and time). Being able to select a group of pages and save them at once to a folder (like save all tabs in one folder), would be handy.

If someone is using a dark theme with Ubuntu, he will probably see all the input boxes and buttons filled with dark colours. This should be fixed, not everybody uses the default light theme.

I think it would be nice if the firefox tab bar could be integrated in the unity menubar.

In intrepid, when firefox opens the dialog to allow you to specify the name and path where you want to save a file; the dialog only shows your local places, i.e. it does not show your network places. So, you cannot save the file in a network share.

The general direction that interfaces are going is favouring the use of buttons rather than text. Nautilus is already using buttons by default instead of a text path and I think that Firefox should and will eventually do the same. I would just like us to give it a little shove in that direction.
This is a Blog post I wrote on the topic, it includes images of the concept.
http://necius.blogspot.com/2008/09/url-button-concept.html

Benefits and Deficits of the design (taken from the post):
Benefits:
- Less issue with 'information overload'
- Would integrate more fully with the modern operating system (the button design is taken from Nautilus in Ubuntu, but a design could be made using the Vista 'arrows')
- Aid usability enabling 'drag and drop' onto the tab bar, etc.
- Easier to go to a higher level of the site.

Deficits:
- Difficulty implementing (with many weird URLs involving numbers and automatically generated content, e.g. this blog ends in 'post-create.g?blogID=944926393326072880'). This could hopefully be overcome using intelligent programming.
- When a user wants to type a URL on a page that already has content, it would require an extra mouse click (This could surely be overcome by someone good at interface design, i.e. not me). Alternatively all users could learn to use 'CTRL + L' :).
- Some users would not accept this very readily, we saw this with the Awesome Bar.

I'm sure there are other positives and negatives, please feel free to comment. Please note that I am not necessarily talking about the near future, but I feel that eventually the interface will go this way and it would be good if we were first.

Always.. i put bug wishlist https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/683987

I just noticed that in 10min I probably closed and reopened firefox .. 5 times.
And although my machine doesn't have a lot of ram, I think I would get things done faster if firefox wouldn't shut down completely every time I closed that last tab.
