Script quits working - this is when multiple tabs are open and I go to close one. First, I have to click to close the tab multiple times before it closes, then a 'new tab' opens on it's own. The script error reads Script: chrome://browser/content/tabbrowser.xml:1644 I have to then close the window, reopen it, and then all previous tabs open, and yet another 'new tab' opens. None of my tabs are closing with one click, all need two or more before they close. I love Firefox and have used for years, this really must be fixed.
Please check if this happens in Safe Mode.
Safe mode disables the installed Extensions, and themes (Appearance) in Tools (Alt + T) > Add-ons. Hardware acceleration is also temporarily disabled - the manual setting is Tools > Options > Advanced > General > Use hardware acceleration when available. Options > Advanced. All these settings/add-ons can also be individually or collectively disabled/enabled/changed in Firefox normal mode to check if an extension, theme or hardware acceleration is causing issues.
It continues to happen in safe mode. I have none of the known problematic extensions. The only ones installed are Photobucket uploader 1.3.3 and Xmarks 4.0.5 I have and use only the original 'theme'
My plugin add-ons are:
Windows Live - up to date, Silverlight plugin - up to date
Shockwave flash - up to date Quicktime plugin - up to date iTunes Application detector - up to date Adobe Acrobat - NOT up to date - downloaded the file, but says I must close Firefox to complete install and even though I close Ff, it still keeps giving me the 'must close' message to complete the update
Did this start after the update?? If you have security software you may have to re-trust Firefox and its supporting files/child processes. You can also try to Disable all the Plugins in Tools > Add-ons.
I don't know which update you are referring too. I can tell you it's been happening a couple weeks now. I have disabled all plugins and it continues to happen
