Speedster by Fooman

• Combines multiple Javascript and CSS files into a single Javascript file and single CSS file, to enable faster page load times
• Reduces the total size of files to be loaded as well as the number of HTTP requests, for empty and primed caches
• Fully automated once installed, with automatic versioning when Javascript/CSS files are updated
• Compresses files without requiring gzip support on your server
• Creates far future expire headers for the combined Javascript and CSS files
• Multi store capable
• Uses the Minify library by Steve Clay (released under a BSD license)

Fooman Speedster is now controlled by an advanced self testing framework. You can only enable Speedster once the configuration has been set up correctly and all self tests run successfully.

Note that the self test does not include testing for existing Javascript errors on your site - it's still important to do this separately before installing Fooman Speedster (see below for details).

Important - Before you Install Fooman Speedster

Please ensure you read and understand all installation and troubleshooting instructions
Ask your Magento developer to install the extension if you don't understand something in the instructions. If you do not follow all steps in the installation and troubleshooting instructions, the installation of Fooman Speedster could fail and generate errors on your site.

Always install Fooman Speedster first on your test site, before installing it on your live site
If any errors occur, it is far preferable to complete our troubleshooting instructions on your test site so your live site will remain unaffected.

Always test for existing Javascript errors on your site before installing Fooman Speedster
Fooman Speedster relies on all Javascript on your store being completely error free. If your store contains existing Javascript errors, these will be magnified when installing Speedster and could cause issues with your store's frontend. The Speedster self test does not include testing for existing Javascript errors on your site. It is important to do this separately before installing Fooman Speedster (you can test with If there any existing Javascript errors are identified on your site, ensure these are completely fixed before installing Fooman Speedster.

Ensure your site meets all system requirements (see below)

We provide Fooman Speedster as a free extension to the Magento community. Please be fair to us and do not post negative reviews for errors which can be avoided by following the installation and troubleshooting instructions (these are comprehensive and cover 95% of all issues reported to us since 2008). Unfortunately the majority of recent negative reviews that have been published via Magento Connect describe errors where either system requirements were not met, or instructions were not followed correctly. Please take care to follow all instructions correctly, and if you believe you have found a genuine error, contact us to report it in the first instance rather than leaving a negative review via Magento Connect. Thank you.

We wish you a successful installation and hope that you are impressed by the results Fooman Speedster can deliver on your store.

System Requirements - Is Fooman Speedster right for my Store?

System Requirements
Fooman Speedster works out of the box using an Apache platform run on Linux. In addition:
• Mod_rewrite (a standard Apache module installed by default on most Linux servers) must be enabled
• .htaccess must be supported
• CSS images must be available under the same domain as the store

Note: Several developers have also successfully installed Fooman Speedster on different platforms by adapting the installation process. For further reading see the ISAPI2 and Nginx threads.

Risk of Javascript Errors
Fooman Speedster has been tested with the default Magento themes and successfully installed on tens of thousands of Magento stores since 2008. However, there is always a risk that minifying and combining Javascript files can produce Javascript errors. We do not recommend using Fooman Speedster without thorough testing on a test site if:
• Your store already contains minified files
• Significant Javascript customisation work has been done on your store and the added non-default Javascript files do not follow best practice Javascript (you can test with
• Your store uses Jquery (or has extensions installed which use Jquery) - although a workaround is provided in the instructions, almost 100% of reported errors are from stores which also use Jquery

Speedster Advanced
Fooman Speedster Advanced uses an advanced caching strategy which combines, compresses and caches JS and CSS files. Click here to see if this extension is right for your store.

Feel free to report any suspected bugs with the extension, however please note that we are unable to provide individual support or troubleshooting advice via our support email address - see our general FAQ for more details. If an error still persists after following the troubleshooting advice above, please either contact your Magento developer or disable the extension.

About the Developer

This extension was developed by and is supported by Fooman

Speedster by Fooman is rated 1.0 out of 5 by 188.
Rated 3 out of 5 by from Developer warns you.... This is a cool extension. It seems to solve most of the issues related to standard css and js magento merging. Untortunately with my custom magento website I faced the common issue of js conflict on my test website due to template issue that override the Fooman_Speedster_Block_Page_Html_Head Mr. Fooman warn us many times, ( and that's a polite and appreciated suggestion ) and told us to test it before going live, and most important he share with us this extension for free, so there is nothing to blame. But the fact is that right now a huge % of magento templates use to modify and override the Block_Html_Head. And I don't think that to disable the template could be a great way to solve such issues.... Some other times I've recognized that some FPC extension ( like potato FPC ) give some issue, but in this scenario you can ask for suggestion to the FPC module developer. With all that being said I was wondering 2 things: 1- why do not add a baseline to solve the most common issues with template js override of the block HTML head? 2- Ok, it is free, but if then I have to pay hundreds of bucks for a freelance developer to fix it is worthless, right? So, follow the instruction carefully, test it in a development environment and cross your fingers. If you are lucky then you should have a great advantage on your website speed ( ...or that's what they say). Sadly For me no luck, but as Mr. Fooman told us several times this extension could not be for everybody. For this reason I will leave a neutral feedback. Just because I was not able to see it working. I do not have enough experience to solve it by myself without any suggestion , and don't have enough money to afford a freelance developer to fix my website. Good luck.

Rated 1 out of 5 by from Stay away this product I wrote a review for them before but the market place required to resubmit review. I make sure to write the review to warn everybody to stay away this product. I run the module and my backend options wasn't accessible. I red the userguide step by step carefully and couldn't find the reason. Support system is not working for now. Then i realized the site is show up with css files had an 404 e.g. Now i fixed it but this choice is the biggest problem in my life.

Rated 3 out of 5 by from Conflict with other extension Hi, after it has been installed the extension test failed with the following error: "Trying to load block Fooman_Speedster_Block_Page_Html_Head returns Sm_Maxshop_Block_Page_Html_Head. Please refresh your Magento configuration cache and check if you have any conflicting extensions installed." Any idea what to do to sort this problem out? Magento 1.9

Rated 5 out of 5 by from Solution for crashed backend Hi to all, When i installed this extension it crashes my backend and some javascript stop working. The solution for this is very simple, in default config dehativate the javascript minification and after that activate by website, so, in frontend the files are minified and in backend not. It Works! Regards, Pedro

Rated 1 out of 5 by from Did not work I followed all the instructions from the guide but as soon as i install the extension (without even running the selftest), my backend crashes. I can only click on dashboard then?! The only thing that i was confused of in the guide was the minifycache folder on the FTP. I could not find it.

Rated 2 out of 5 by from Cannot Install OK, i have tried installing this with no success at all. It simply fails to enable the plugin. I have checked all the steps. The permissions are correct no issues there. It shows the http 4.0 error described in step 1 no problem, i can view the print.css file minified also.. However it keeps failing on self test with the following message: Selftest failed with: Step 1 - OK Unable to Connect to ssl:// ssl:// ssl:// Starting Fooman_Speedster_Model_Selftester Default store loaded Magento version: Speedster DB version: Not installed Speedster Config version: 3.0.14 Checking file locations Checking rewrites Checking database Result: success Self-test finished Could you kindly let me know how to fix this so I can use the extension? thanks in advance..

Rated 5 out of 5 by from Works also with jQuery This extension is great, I'm successfully using it on Magento v1.9.1 including a bunch of extension. -) Works with jQuery (or extentions using jQuery) if you follow some simple rules like e.g. using jQuery.noConflict() and jQuery() instead of $() -) Works on Plesk 11.5 with nginx proxy without any additional configuration on Apache or nginx -) Works with Soczed LessCSS preprocessor -) Works with Mirasvit Fullpage Cache and Mirasvit SEO suite (after a small change in code done by Mirasvit support)
