After a day of Minecrafting and playing outside with my nephews and niece, I was surprised last night to find yet another Firefox 4 beta had been released. Firefox 4 – Beta 12 is now available for download. So what has changed since the last beta? The big fix this time around is when it comes to delivering better performance when watching online videos.
Firefox 4 Beta 1 is out and ready for the testers. So what is in store for this first beta of the forth version of Mozilla’s browser? There are dozens of major features and improvements – so Mozilla is looking for people to test them out, and report your bugs so that they can get Firefox 4 out to the public at large.
Did you know you can tidy Firefox up, with VACUUM? No, I do not mean that thing you use to clean your carpets. Here is a way to VACUUM your places database from within the browser.
Here are the steps you need to take:
1. Open the Firefox tools menu and click on error console.
2. Paste the following command into the code box as a single line:
3. Hit the “Enter” key or click the evaluate button.
The user interface will freeze for a moment, but after you are done, your SQLite databases should be less fragmented than before, leading to a leaner and meaner Firefox browsing experience.
Thanks goes to Mozilla developer Jeremy Orem for this fantastic tip!
Bonus – Vacuum Places Improved is an add-on that will do this for you automatically.
Some have discovered a new project from the Mozilla Wiki documenting the first steps and timeline for Firefox to become a multi-process supporting browser. The project in question, simply known as Content Processes looks to separate processes to display the browser UI and web content.
Here are the current initial goals:
- Provide better application UI responsiveness
- Improve stability from slow rendering or crashes caused by content
- Improve performance, especially on multi-core machines
Now why do this, and what does it even mean? Well, both Google Chrome and Internet Explorer 8 have moved in this direction for increased stability. For an example, with multi-process support, a single tab crash wouldn’t take down your entire Firefox browsing experience. It would only effect that one tab, because it would be seen as its own process.
It might be a year or more before we see this in action via our own Firefox installations, however it is nice to see that Firefox is always looking to expand and check into other areas of stabilization to see if we can all benefit from it.
We are getting closer to a final release for Firefox 3 and that is the sort of thing that just makes me all happy inside. Not much is really known about the Firefox 3 RC2 release as far as what has been improved. In a general nutshell it is said they fixed some reliability and performance issues. For me? It is just as awesome as Firefox 3 RC1 was, so thank goodness for little things.
You can download the Firefox 3 – RC2 at the Mozilla web site if your feeling like you want to do a little testing. If you have RC1 and you want to move to RC2, just go up to “Help” in the menu bar, then “Check for Updates”.
Check out the release notes for yourself and then download if your ready to take the leap. Once again, must say this isn’t the final version just yet, so unless your just overly curious like some of us – might want to wait before downloading.
This is a ‘bit of news that might have been missed by some. It looks like Firefox 3 continues to gain praise for having a significant reduction in the amount of memory it uses over Firefox 2.
Over at Ars Technica this is what they are saying:
During intensive browsing with approximately 50 tabs, I have found that Firefox 3 generally consumes less than half of the memory used by Firefox 188.8.131.52. Firefox 3 is also snappier and more responsive when switching between tabs and performing other operations that typically lag in Firefox 184.108.40.206 when the browser is experiencing heavy load.
This is great news for any Firefox fans out there. Over the recent years the memory problems seem to be the big sticking point for a lot of people. Has this mountain of an issue finally been solved?
Firefox 3 has a lot of nice new features, the design is slick and it promises to be yet another Mozilla home run! Now a lot of people could really care less about those three facts because much of the Web is much more considered with how fast Firefox 3 is going to be. Well thanks to Ryan over at CybernetNews.com we have some numbers for you.

Which one gives you a better performance? Is it better to have multiple tabs open in one window or just have multiple Windows open? The Firefox Guru did all of the scientific work on this one, and has found out the results for us.
Over on Go Firefox!, an interesting question was posted: Which uses less system resources (memory)?
My theory is using tabs would use less resources then having the same sites opened in separate windows. My reasoning is each window has to load the entire browser interface, not just the page content. So, I did a little experiment. First using Firefox 18.104.22.168 with a clean profile (no extensions, no plug-ins and default theme) and imported my bookmarks from another profile.
