To solve this, you can start by open Firefox in safe mode and see if the problem persist. If it doesn’t, enable the add-ons one after another to pinpoint which one is causing the memory leak.
I just got my very first self-made Firefox add-on approved on AMO (https://addons.mozilla.org). It’s a simple add-on that shows a notification in the operating system when a YouTube video starts playing. Maybe a bit pointless if you are watching videos, but it may be useful if you are using YouTube to listen to music in the background. It’s called YouTube – Now Playing Notifications and can be found here:
As I said, this is my very first add-on, and I must say that I really like Mozilla’s developer tools. Developing an add-on with their add-on SDK is really easy and it’s also really easy to upload add-ons to AMO.
Apparently has the dudes behind Linux Mint decided that they want their own Google search engine in Firefox, which lacks many functions. Here follows some steps you shall take to change it back to the default search page:
In Firefox for Windows, you are able to double click a segment of the URL in the address field to select it. By default, this isn’t possible in Firefox for Ubuntu, instead selects a single click the whole address. Luckily, this is easy to change, which you can do by following these steps:
Open a new tab.
Type about:config in the address bar.
Press the I’will be careful, I promise! button.
Type selects in the filter field.
Change the browser.urlbar.clickSelectsAll entry to false by double clicking on the row.
Do the same as above with the browser.urlbar.doubleClickSelectsAll, and make sure both are false.
I don’t know why it doesn’t work to edit the tab width by editing the following two preferences in about:config in Firefox 4 Beta 4:
But I found the add-on Custom Tab Width that does the job! The strange thing is that it looks like the add-on changes those two preferences, and that apparently works. I guess that the add-on edits something more… But it works!
