Alen's questions

Several days ago I noticed that "Hide bookmarks toolbar" option is missing, I used to use this option when I right click at the top of the Firefox window. Then I tried to hide it by clicking on View -> Toolbars and then I should uncheck the Bookmarks toolbar but it's missing here too. When I click on Customize I used to see Bookmarks toolbar at the bottom of the page under Toolbars menu item, but I can't see it here too.

I tried restarting without addons and I also refreshed the Firefox, didn't help.

This question is originally posted on Firefox support so I'll paste the link in case someone needs some info: https://support.mozilla.org/en-US/questions/1209543

I'm using Ubuntu 16.04 and after some time (I guess this started to happen after I updated Nvidia drivers) my computers began to boot very slowly. I tried to deactivate some unneeded services but it didn't help. I ran dmesg and I noticed some really large gaps. Here is the full log: https://pastebin.com/d4EVfi8r

I hope someone will help me with this.

I already asked this on Firefox support but still no anwer so maybe someone here knows how to fix this.

After I updated Firefox to version 39 I can't use it at all, it crashes all the time, I couldn't even write this question from Firefox. I clicked on "Refresh Firefox" button, also I restarted with addons disabled, also I reinstalled Firefox but none of that helps. Crashes are random, after 5-6 minutes of browsing.

You can see crash reports here: https://support.mozilla.org/en-US/questions/1071421

EDIT: I installed developer edition of Firefox and no crashes so far

I'm trying to see 360 You Tube videos but they are not working. I'm using latest version of Chrome, html5 player and I enabled hardvare acceleration but it's still not working. I can see flat version of the video.

What can I do to fix this issue?

Today I decided to try Gnome shell 3.10 on Ubuntu 14.04 and I noticed that after every restart my screen resolution is set to maximum which is not desirable. In Unity I don't have such problems. Also if I try to change resolution with nvidia-settings I get this error:

ERROR: Error querying target relations


(nvidia-settings:31370): IBUS-WARNING **: The owner of /home/alen/.config/ibus/bus is not root!
The program 'nvidia-settings' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
  (Details: serial 544 error_code 2 request_code 157 minor_code 25)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Is there any fix for this?

How can I disable Dash reveal animation. When I try to open Dash it takes up to 2 seconds to open it, that's slow for me. I noticed it uses fade out animation while opening so I think when I disable that animation, reveal time will be much shorter.
