Browser JavaScript Explained
Browser JavaScript is a feature that allows Opera to automatically fix incompatible Web pages, out of date scripts, and pages that inadvertently block Opera. The script file is automatically distributed by Opera Software ASA, and can be used to apply fixes to specific Web sites, and specific scripts.
Browser JavaScript respects your JavaScript preferences, and will not be loaded if JavaScript is disabled.
Current browser.js status: checking... How do I enable it?enabled.
Target version and time stamp of the active browser.js file is .
Note: Opera also provides User JavaScript, which allows you to apply your own enhancements and fixes to Web pages. Additionally, Opera Software ASA runs the Open the Web initiative, which contacts the authors of problematic Web sites.
Keeping up-to-date
- Opera automatically checks for updates to Browser JavaScript once every week. Any updates will be automatically downloaded and applied the next time a page is loaded in Opera.
- Automatic checking is controlled by the
Browser JavaScript and Check For New Opera settings in Opera6.ini.
- Files are downloaded separately for each user of Opera, and you do not have to be an administrator of your computer to make use of this feature.
- The Browser JavaScript is signed and distributed by Opera Software ASA, and should not be edited.
- The file will be stored in Opera's profile folder. The screen will tell you where the profile folder is.
If you use a proxy server that requires user name and password to access the internet, please note that Opera will not request user name and password for an authenticating proxy in order to download site patches. Site patching or upgrade notification may not take place if such proxies are required, but you may be able to check for updates manually.
Enabling browser.js
If you have changed settings, or changed the file itself, the browser.js feature may have become disabled.
- Go to the Browser JavaScript setting and change the value to 2.
- Click the "Save" button below the setting.
- Re-load this page and check if the status message at the top says browser.js is enabled.
If this doesn't work for you, the file may be corrupted. Please follow the instructions on "checking for updates manually" in the next section.
Checking for updates manually
Opera downloads the file automatically once a week, but if you want to make absolutely sure you have the latest file you can follow these steps:
- Go to the Browser JavaScript setting and change the value to 1.
- Click the "Save" button below the setting.
- Use in Opera's menu bar.
Opera may tell you no new Opera version is available, but it will still check for a new version of the browser.js file.
Patches applied by Browser JavaScript
In most cases, when Browser JavaScript applies a fix, a message is posted in the JavaScript console () saying that the page has been changed.
Please note: Some of the fixes apply to specific Opera versions, or on specific platforms only.

Note to webmasters
There are several reasons why Opera might modify your pages. These include:
- Opera may prevent a browser detect on your pages from causing problems.
- Opera may fix incompatible, invalid, out-of-date, or problematic code used on your pages.
If you think Opera is modifying your page incorrectly or unnecessarily, or if you have removed the cause of the problems, please report it in our bug tracking system.
If you wish to disable Browser JavaScript to allow you to test your fixes, you can do this by setting Browser JavaScript to 0 in Opera6.ini. A quicker way to do this is to access opera:config#Browser JavaScript, since toggling this setting in opera:config does not require restarting Opera.
