How to change 'open link in new tab' behavior in Firefox 3.6 back to the old style.

I downloaded Firefox 3.6 yesterday and I see that the 'open link new tab' behavior is changed. In the previous version, an opened new tab will be inserted at the rightmost in the tab pane but now the new tab will be inserted next to the current related tab. It's just a style but I like the old one.
To change it back to an old style. Steps are below.

• Enter about:config in the location bar.


• Press "I'll be careful, I promise!" button. yes, you have to be careful about this.


• Type tab in filter box as in image.
  
  
  

  
  
• Find the preference name browser.tabs.insertRelatedAfterCurrent and double click it. The value of this preference will be toggled to false.

That's it.

How to Fix Firefox always keeps showing "Restore Previous Session".

Today, my ubuntu crashed while I was using firefox. I rebooted and everything seem fine except one thing. Firefox show "Restore Previous Session" dialog everytime I open firefox.
Even though I've shut it down properly , the dialog keeps showing.

I googled around but I had no luck. I think that the problem is firefox config files may be some corrupted because of the crashing. So I went around in ~/.mozilla and try out some way and PONG! It's fixed! :)

Here is the solution.

1. $ cd ~/.mozilla/firefox/fwegtctl.defaults (you may change this to your firefox profile directory)
2. $ mv sessionstore.js sessionstore.js.bak
3. Restart the firefox.

Just simple. I guess that sessionstore.js saves the data about session (its filename tells that. HAHA) and firefox on opening will see whether this file exists or not.
Good Luck!
UPDATE : I've just found that there is another problem. The problem is the location bar doesn't update anyway. It's still stay blank or some url and when you change the tab it's doesn't effect. The location bar search feature also off. I don't know this problem and previous problem if it's an consequence. I spent a hour finding out the solution in the .mozilla/ (yes, again!)
at last, the solution is right down.

1. $ cd ~/.mozilla/firefox/fwegtctl.defaults (you may change this to your firefox profile directory)2. $ mv places.sqlite places.sqlite.bak
3. $ mv places.sqlite-journal places.sqlite-journal.bak

I hope that these soulutions will work for you.

Firefox 3 beta 5 lags on ubuntu 8.04

I upgraded from Gutsy to Hardy last week. It comes with the new Firefox 3 beta 5. After I had used for a few days, I found that firefox lags very much. When I switch the tab or scroll the page or just leave it , it start to lag the system and then system sometime freeze after that. In the system monitor, firefox process was interruptible. I noticed the harddisk light always show or blink fast but I'm not sure it's the same case.

At first I though that it resulted from upgrade process that it's not a fresh install. Maybe some configs file are not upgraded correctly. After few days passed, I felt very annoy. I started to find out what it is.

I found this bug. It's the same. In the bug page they give a method to solve this bug temporarily
There is an easy workaround.

This workaround is successful:
1. Open Firefox 3
2. Disable phishing/attack detection in the security section of the Preferences
3. Close Firefox
4. Make hidden files visible (Locations - Personal folder - View - show hidden files)
5. Delete /home/user/.mozilla/firefox/blahblahblah.default/urlclassifier*.sqlite
6. Open Firefox.
7. There is no next step. You're done. :-)

Greetz, Pjotr.

I follow this instruction. It works!!

I like the bug report system too much. haha

I hope that the patch will be published very soon. I wait for it.
