On my Mac Book Air 2015 there is no About Firefox in the Help Tab. So I can't see a current version of Firefox and other features from About Firefox. Also some addons are not working properly (Spoof Timezone for example) and I think that there is some connection between these issues.

Two days ago I installed Thunderbird for the first time and so far I like it very much. Today I discovered that some functions on my keyboard are out of order. These problems include the inability to type the symbols on top of the number-keys and the PrtSc key ( which I use often). I'm a novice computer user so they may be additional problems. Could you please help me resolve these problems with my keyboard? As one with little knowledge of computers, I know that my problems would go away if I uninstall Thunderbird, which I love so far. Could you guide me gently (In simple terms) of how I can resolve, myself, any conflicts that Thunderbird keyboard shortcuts have with the actual use of the keys on my key board. I thank you in advance, since this support forum helped me a lot already, Dimitri

Hello!

Apparently I was logged out of FireFox on my iMac, but fortunately still logged in to on FireFox on my iPhone. After being logged on again to FireFox on my iMac I had no stored usernames and passwords anymore, again fortunately I still had them on my iPhone. No matter how many times I synchronize; I still don't get my saved usernames and passwords from FireFox on my iPhone onto my iMac (hopefully the sync will not work viceversa as then I will loose all saved usernames and passwords).

Please help!

Since Facebook forced me to switch to new layout a few months ago, Facebook on Firefox (fine on Safari) does not scroll At All (goes about 2 cm beyond first page). Everything else seems to work fine. However, it's basically not usable on Firefox - can see part of the first post and that's it - 'yer stuck' (quite frustrating). Thanks for any/all help.

Hi, I have been having trouble remaining logged in at the Youtube website. I go to the Youtube.com main page and click "Sign In." It logs in using my Google account. However, if I click on any video on the home page, I am logged out again. I have tried signing in and signing out of Google. I tried clearing my cache and cookies. I also used the "Refresh Firefox" option in Firefox settings and I still have the problem. Is there any way to fix this? Thank you in advance. I am using Windows 10 for my OS.

When viewing a video powered by a Brightcove player, the playback control bar on the bottom does not hide when entering full screen mode. I have tried moving the mouse in all areas of the screen, play/paused it with the spacebar/mouseclick, and tried several other methods but it simply does not want to disappear. An example of a website that uses the Brightcove player is the IPL website. You can click here to access one of the videos on the site.

I have tested this with other browsers and the playback control disappears as it should when entering full screen so it seems to be some issue with Firefox. I recently contact Brightcove support and they were not able to replicate the issue on their version of Firefox and just recommended I use a different browser. But it would be really helpful if someone could help me fix this strange bug.

Thank you.

What should I do? Thanks!

I have a number of email addresses and I find that if I send an email to someone using an address other than my default address, the person replies to the address that i sent from but my reply to them is sent from my default email address rather than the address that the person replied to. Is there someway to ensure that the email address doesn't keep reverting to the default withour me having to check every time?
