Switching from Opera to Firefox

Once again I am trying my traditional attempt to switch from Opera to Firefox. Why is this a tradition now? It seems every time there is an update to Firefox, everyone goes on and on about how great it is and I attempt to try it out, only to be disappointed in the end. I think the disappointment isn't all of Firefox's fault. Some of it is that it doesn't quite have the power of Opera at first test, and at the same time it just wasn't what I was familiar with.
Some things have changed though. I now use Firefox daily at work. So, I am now pretty familiar with the subtle differences in Firefox. But there are still so many things that I take for granted in Opera that aren't found in the standard default Firefox install. In the past I have tried to supplement this with the many extensions that are available. I think I have now found the right combination.
So far, I have installed the following extensions to get Opera-like functionality:

Tabbrowser Extensions, this was absolutely necessary, provides endless customizations for the tab features, greatly surpassing anything Opera can do. The default tab features are Firefox are way too basic.

All-in-One Gestures, gestures are one the the great features of Opera. I am a mouse guy, and gestures allow most features of browsing to be done with quick swipes of the mouse. This extension probably outdoes the Opera implementation.

Translate Page, though not a built-in feature of Opera, Opera is very customizable through INI files, so I was able to add in this feature in myself. It's always nice to be able to translate foreign pages on the fly.

Paste and Go, allows right-clicking in the address bar and pasting the address and opening it with one click.

Allow Right-Click, doesn't allow Javascripts to take over the right-click context menu.

WMLBrowser, to view WML (WAP) pages

I have also installed some other extensions to make my experience more enjoyable. I have the Gmail Notifier, EditCSS and AdBlock.
Gmail Notifier is something that is not really needed since I am also using the offical notifier from Google that sits in the system tray, but I figured I would try this one out also since I might like it better.
EditCSS is great for editting webpages. I still am pretty novice with CSS and make a lot of mistakes and it takes me a LOT of trial and error to get pages to look the way I want. Since EditCSS always realtime viewing of CSS changes, it speeds that process up a lot faster. On my other computer, this was the only reason I kept Firefox installed was for the EditCSS extension.
AdBlock is a pretty interesting extension. Works pretty good too. I normally am not against advertising on webpages. (Well, expect for pop-ups/pop-unders, I have no problem blocking those) It's a necessity and the web wouldn't exist as it is today without ads. Pages have to make money somehow. But, I have always had trouble with Tribalfusion ads at 1SRC. They don't load properly too often and it's real annoying. And, recently they have been using a lot of Flash ads, and at 1SRC, the ads are placed right under the nav menu. But, of course, the menu goes behind the ad, so if there is a Flash ad on the page, you can't use the nav menu very easily. So, if ads are making a page unusable, I will be blocking them.
At this point, I think I am pretty happy with how things are going. I figured out how to set it up with the Tabbrowser extensions to save the open tabs when closing Firefox and have them reopen next time. This was one of the things that I didn't want to lose from Opera as I normally have tons of tabs open and I never get to everything at one time, so I need to have the browser come back next time I open it up.
Also, the Tabbrowser extensions have the ability to open previously closed tabs. This feature hasn't been in Opera for too long, I think it might have been introduced in version 7, but it's nice to have. Accidentally close a tab, and you can have it back with no trouble.
I think this might be the final test and I may actually switch over this time. Opera is a great browser, but I think it's best days are past. Firefox will likely improve at a faster and faster rate, and it is quickly becoming a standard. I don't think Opera will be able to hold on to it's user base for the price that it charges for it's desktop app if there is a free app as good as Firefox.
