If you regularly use Firefox Aurora and Firefox Nightly it happens once in a while that add-ons become marked as incompatible. To enable those add-ons, follow these steps:
- Install the add-on Nightly Tester Tools (you don’t have to run Firefox Nightly to use it) and restart the browser.
- Now click the menu option Force Addon Compatibility under Tools > Nightly Tester Tools.
- Restart the browser and you should be able to enable the add-ons that earlier were incompatible.
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.
I just updated my Firefox installation under Linux Mint 10, so now I’m apparently using Firefox 7. Can’t say that I have seen anything new from what is in the Firefox 5 beta, but whatever.
Because I updated Firefox it disabled all my add-ons, as usually. To get them working again in Firefox 7.0a1, follow these steps:
- Open a new tab.
- Type about:config in the address bar.
- Right click anywhere on the page and click on Boolean under New.
- Enter this as the preference name: extensions.checkCompatibility.nightly
- Click OK.
- Choose false and then click OK again.
- Restart your browser and all your add-ons should be runnable again.
Since we don’t have to type in the version number in the preference name any longer (extensions.checkCompatibility.XXX), I suppose that we won’t need to update this in future versions of Firefox.
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!
The version that you can download from the official Firefox addon page doesn’t seem to work in Firefox 4 Beta 3 (which that I’m using). But I found after some googeling a post with a link to a working beta version of Greasemonkey that works in FF 4 Beta 3.

One awesome addon to Firefox is Better GReader, which adds extra features and settings to Google Reader. My two favorite features in this addon, are the preview function and the ability to change skin of Google Reader. With the preview function am I able to open sites in a window in Google Reader, without having to mess with new tabs and stuff like that.
Hrm… I don’t know what to say more about this addon. Check it out on the link below:
Smart Bookmarks Bar
Smart Bookmarks Bar is one of my favorite add-ons to Firefox, and the lack of it in Google Chrome is one of the reasons that I have hard to like that browser.
This add-on hides your bookmarks’ names on your bookmarks bar, and shows only the favicons. You can also choose to show an bookmark’s name when you hover over its icon.
This is really useful and makes it possible for you to have dozens of more bookmarks on your bookmarks toolbar. I have almost 30 bookmarks on my bar (after some cleaning) and I can’t imagine how it would be without this smart add-on. You should definitely check it out!
With Fission you can add extra functionality to your address bar in Firefox. You can either transform the address field to a progress bar and show the progress behind the address, or you can add a progress bar to the right of the address.
It is also possible to show connection status at the right of the address bar, which tells you what currently is loading on the website, like if you are watching a streamed video.
I recommend this add-on because it adds extra functionality( to your already awesome web browser), and it looks really good.
