Firefox is speedy, secure, and entirely cross platform compatible, and is now my primary web browser of choice. One of the better ways to improve the user experience with any application is by learning some essential keyboard shortcuts, so here are fifteen such shortcuts for Firefox.

Hi, I recently bought a new MacBook Pro, running OS 10.7.4. I previously had been using the Zotero plugin for Firefox on a MacBook under OS 10.6.x without any problems. Since I got the new machine and installed Firefox 15 and the latest version of Zotero I am having major issues.

Every time I try to use a drop-down menu (right-click, etc.) in Firefox the entire system freezes and I have to manually for a re-boot, losing any work I have open. I have tried everything (rebooting Firefox in safe mode, disabling all the plugins and add-ons, resetting Firefox, etc.). I thought this was a Firefox issue, however I just tried to use the Zotero 3 stand-alone client, and the exact same problem occurred when I tried to use a drop down menu - the entire system froze, and I had to force a reboot. This is a serious problem! I am writing my PhD thesis which is half done and all my references are in Zotero! I can't add or edit any of my citations which is seriously stalling my progress and I need to submit the entire thesis by March! HELP PLEASE!!!!

Ok, further developments. Still can't get Firefox to work; it makes Lion hang and I have to force a reboot. I tried using terminal to open FF's profile manager, delete my old profile and make a new one. Same problem. I tried making a new user account in Mac OS, and doing another fresh install of Firefox. I was able to use drop down menus and right click without crashing the system!

However, as soon as I installed the Zotero plugin. The same issue started occurring again. Dear programmers, please help me. It will literally take me weeks of work to re-do all of my citations using a different software or manually. There must be a way to fix this problem! Which versions of OS X, Firefox and Zotero are you using? Have you installed any other programmes which alter or add functions to the right click menu?

This kind of crash is very unusual. What information is there in your crash logs. You can look at them in console.app (found in utilities).

Can you move your zotero folder, found at somthing like ~/Library/Application Support/Firefox/Profiles/tt1yz7pi.default/zotero (your.default will be different I guess) to another mac or even a windows machine? Perhaps you could even use this folder with a copy of Zotero stand alone. How to recover replaced file on microsoft word for mac 2008. Have you looked at using Zotero stand alone as an alternative? Have a look at On the same page there is a link to a list of extensions which are known to conflice with Zotero. Don't despair. If the needs be you can always copy your Zotero library folder somewhere else and work with the sql using something like sequelpro (www.sequelpro.com) but that probably won't be necessary.

Even in safe mode, with all plugins and add-ons disabled, if the Zotero plugin has been installed, Firefox will cause the system to freeze. But the problem goes away if you uninstall the Zotero extension? (Uninstalling Zotero won't affect your data, so please test this if you haven't.) Does this happen for any context menu (e.g., on the Firefox toolbar), or just if you right-click somewhere on the webpage? Also, this really takes the whole system down? You can't, say, option-right-click on Firefox in the Dock and force-quit it? This is a pretty strange issue.

If you go to System Preferences, 'Users and Groups' (or maybe 'Accounts' in Lion?) and go to Login Items, is there anything unusual there that might be conflicting?
