Troubleshooting Open Tab Problems In Firefox 4.0

Hopefully someone out there would find this article useful. Since Mozilla Firefox 4.0 was released, it has taken just a little bit of getting used to. Perhaps, one of the most notable issues is getting your browser to remember the last browsing session. I first noticed this when, as usual, I had about 50 tabs open at the same time. The reason for leaving so many pages open at once was because I thought each one was quite useful and I was unable to read or use them in detail at the time of asking. However, I also made the mistake of assuming that my last browsing session would be restored after closing the browser or at least there would be a warning alert with an option of remembering the pages I had last been on.

Alas, that was not the case, I lost everything and had to go through the pain of searching for every page in the browsing history. Unfortunately, that was an impossible task as there was no way anyone could remember 50 pages off hand. So then, what should be done if you found yourself in a similar situation?

The Solution

The solution is simpler than you could ever imagine, if only someone told me that :). I had imagined something slightly more complicated after looking through the options menu-item to no avail. The entire process is illustrated by the following images.

Basically, you have to go to the main (orange) Firefox tab or File menu, Select Options, then Options again. Once the Options box is displayed, look for Startup under the General tab, then select “Show my Windows and tabs from last time” just after “When Firefox starts”. Click OK to save.

    I still haven’t even noticed what makes Firefox 4 better than Firefox 3 or more importantly the new IE / Chrome.

    Is there an article here explaining Firefox 4 new features?

    I have not tried Firefox 4 though I find this article very helpful should I try it out soon. I have Firefox 3 but I use Chrome all the time. Do you know what Firefox 4’s advantages are over them?

    Yep, that one setting has saved me so much hassle, it’s ridiculous. I wish Firefox would produce an option to save tabs on closing no matter how many instances of FF you have open.

    You would think it would have been a lot more complicated then that. I had to completely wipe-out my hard drive and re-install everything on it. When I went to install Firefox, I couldn’t figure this out for the life of me and have been using IE since. I’m going to have to go chance in now. I can’t believe it was that simple!
