New window JavaScript links that specify window size are opening in a new tab instead.

Before upgrading to 7.0.1, the default option "open windows in a new tab" would only do so for target="_blank" links and JavaScript functions that did not specify new window size. If a JavaScript function included size in the features attributes, a new window would still open for proper display of the new content.

Since upgrading to 7.0.1 on Mac, however, all new window links open in a new tab. Tested on two different Macs and confirmed in the about:config that values were set as follows:

browser.link.open_newwindow=3 browser.link.open_newwindow.restriction=2

Chosen solution

No problem here on Linux to open such pop-ups in a new window.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

That didn't actually resolve my problem. I still saw the same behavior in safe mode and the default theme. However, I did figure out that the link I was testing was not scripted in an entirely kosher way. It seems that other browsers and earlier versions of Firefox are more forgiving of syntax errors in JavaScript than FF 7.0.1. If the window.open method is used properly, I've found that it works fine.

Thanks for the help. I'm clicking the "Solved It" button on your answer to close this out.
