Hi. I made a dumb mistake and installed an add-on or extension (not sure which) that I was hoping would allow me to view YouTube videos in full-screen. Unfortunately I can't recall the name of the add-on/extension.

The problem is, now every time I open Firefox it opens in "full screen" and NOTHING (including F11) will allow me to access the taskbar, the address bar, or any of the other Firefox controls. I can't do anything at all but view the home page in full-screen! The only option I have is to hit control-alt-delete and close Firefox.

I tried uninstalling and re-installing Firefox and this didn't solve the problem. Please help. Thank you!

P.S. I'm writing this in Internet Explorer since I currently can't use Firefox.

Over the years I have frequently had problems with the Latest BBC News Add-on after a Firefox update (hence my previous questions on the same topic), but after this morning's latest update I just don't know what to do. The BBC icon that was previously on the add-on bar in the lower right-hand corner of the screen has disappeared. The add-on bar is visible, and the BBC icon has not ended up somewhere else, such us on the customization menu or on the tools menu. This add-on is 'signed', and so I cannot understand why the icon is no longer present on the screen. I've tried uninstalling and reinstalling the add-on several times, but to no avail. Until late last night, it was working perfectly. Can someone please help me?

Just a thought. I had a Complete Theme that I really liked called Silvermel. With the latest updates it is no longer compatible with Firefox. I went to Complete Themes in Firefox Addons to see if I could find something else I liked and found that 95% of them are not compatible. It isn't as bad with my other addons as with Complete Themes but I still loose the use of 1 or 2 addons when Firefox is updated.

Firefox is always talking about how customizable they are and then their advances render it less so. Improving things to the point where you are dis-improving them it is counterproductive. Would you ask the Firefox developers not the change the things that addons need to be usable? If they can't do that then they shouldn't update it. Thank you!

I'm making automatic installer for special Firefox extensions. I have read couple of articles about that, but none of the described methods are not helped. What I tried to do:

- Placed .xpi file and unpacked unpacked extension directory in %FF_DIR%\browser\extensions
- Placed .xpi file and unpacked unpacked extension directory in %FF_DIR%\extensions
- Placed unpacked extension directory in another directory and added record in registry (`HKLM\Software\Mozilla\Firefox\extensions`, key is extension id and value is full path to unpacked extension)

In all ways name of unpacked extension directory was:

- Random name
- ID from install.rdf #1 (`{ec8030f7-c20a-464f-9b0e-13a3a9e97384}` for example)
- ID from install.rdf #2 (`prism@developer.mozilla.org` for example)  

And, as i said, all methods don't give me expectable result. Firefox don't show extensions in list and don't show any notification. How can i solve it? What actual method using in current version of FF? Target browser is Firefox 41, system - Windows 7 x64 Thanks!

I recently updated to FF 42. I have been using the AutoPager Fixed version for a long time and now it has stopped working. Not being a very computer savvy person I don't know how to search for or create rules that Autopager need to work on the site I use it on. generally when installing AutoPager it will ask what mode yo want it to start in. Lite or Normal. Lite has never worked well so I use normal. It will then ask if you want it to search for rules for the site on-line I click yes. Usually if there is a rule it will tell you a rule has been detected for this site and asks if you want AutoPager to use that rule, clicking yes and refreshing the page always does the rick bt now I'm not getting the message that a rule is available or has been detected. I only use AuoPager on one site. it is a game that requires me to scan 499 pages so it is very useful as opposed to using the side arrows. Any help would be very appreciated.

My Firefox has just automatically updated itself to version 42. The extention page under add-ons does not show the extensions I have installed. The plug in page shows the plug ins I have installed. How do I fix this? This happened on my Windows 7 64 bit partition. I installed the ' Classic Add-On' extension to see if it would fix the issue. Sadly it did not. I have a screenshot. I am unsure if I am permitted to upload it to the media gallery. I also use Linux but I have not done an upgrade therein yet.

Foxytunes is long gone, but the listing won't go away. I've used Safe Mode to remove possible offending registry keys. I tried using the Microsoft tool for this, but don't have the "28 character code" for Foxy Tunes. I'd like this listing gone, especially on account of the fact that attempting to remove it makes Firefox 'misbehave.' If this is too obsessional INYHO, please say so. Also is you could provide the 28 character code for Foxytunes, I could try the Microsoft tool again.

In the same menu bar adjacent to the favourites star an icon exists that opens with the name 'Supported sites' and it holdds all the history of sites visited (this is not the history folder). I have the site set not to remember history. Down to brass tacks; all I want to do is permantly get rid of this icon (Supported sites) and it's history. I have started Firefox in safe mode and the icon will not be visible. But, as soon as I re-open firefox yes youve guessed it the bloody icon and all it's contents is still their.
