When I have a folder of bookmarks in my bookmarks bar, the bookmarks in the folder don't respond at all to right-clicking - this means I can't edit or delete them without moving them out of the folder. Is this normal? If not, is it fixable?
This is not a normal thing for Firefox to do.
Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
(If you're not using it, switch to the Default theme.)
Once you get the pop-up, just select "'Start in Safe Mode"
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.
To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
Please report back soon.
I have the same issue and neither of the Safe Mode or the Firefox Reset solved my problem - if I have a bookmark in a folder, I can't right-click on it ...(MAC - Mavericks)
backup bookmarks reset firefox or reinstall restore bookmarks this fixes the issue
I also tried safe mode and it didn't change anything (and I don't have any extensions or addons installed).
I tried backing up and restoring my bookmarks a couple times, also no difference.
I recommend creating your own thread with the details of your operating system. Please post the link when you have done so.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

Does this issue occur on another Firefox profile?
On Mac you can make the modification in the Bookmarks Manager (Library) in the Details pane at the bottom right or possibly in the Bookmarks sidebar via the right-click context menu.
