Firefox 32 Arrives With New HTTP Cache, Public Key Pinning Support
An anonymous reader writes: Mozilla today officially launched Firefox 32 for Windows, Mac, Linux, and Android. Additions include a new HTTP cache for improved performance, public key pinning support, and easy language switching on Android. The Android version is trickling out slowly on Google Play. Changelogs are here: desktop and mobile.
That's probably a side effect of the "Javascript always on" thing Mozilla did a few versions ago. When they got rid of the "Enable Javascript" checkbox, they also got rid of the options like "Allow scripts to take right-click" and other options.
What's likely happening is your website is blocking right-clicks on purpose (usually as a "protection" measure so you can't right-click and activate extensions like Nuke Anything or Save As).
Of course, the default setting of the checkbox was to disallow websites from hijacking right-click. But since it's gone, so is the setting, so websites are free to hijack right-click.
You need to either use NoScript to block the offending Javascript, or hold down shift when you right-click, which bypasses the right-click hijack and shows the Firefox right-click menu and all the extensions.
