It’s very useful to learn about nem Javascript frameworks for instance :)

Install a Greasemonkey script from a local file

Problem
You have downloaded a Greasemonkey script but… how to install it?

Solution
Here I suppose you have the Greasemonkey add-on installed (Hey, what is GM?). Well, I didn’t find anywhere the option “install from local file“. A GM script is called *.user.js and if you open the URL (http://...) of such a script, GM will recognize it and offer to install it (for this GM must be enabled). However! If you open your script locally (file://...), nothing happens. WTF?

Calm down. You know Python, right? The Swiss army knife of programmers. Just navigate to the directory where the GM script is located and start a web server:

$ python -m SimpleHTTPServer

Now open the URL http://localhost:8000 , click on the user script and GM will offer to install it. Python, what would I do without you?

User scripts are installed in this directory: “~/.mozilla/firefox/xxxxxxxx.default/gm_scripts“. Here you will find a config.xml file too that is created by GM.

Example
I installed this way this script: Greasemonkey: focus first input field. This script puts the focus on the first input field. I use it with Amazon and IMDB and works like a charm.

Siphon – Add-on Synchronizer for Firefox

Problem
You have Firefox on several machines and you want to have the same add-ons everywhere. Also, when you re-install a machine, you want to have back your favorite add-ons.

Solution
“Siphon will manage and sync all your Firefox Add-ons with your different computers. It will also save your Add-on list if you ever need to reinstall Firefox.”

Hide an HTML element on a website

Problem
You have a favourite website which contains an HTML element that bugs you. You simply want to get rid of that element. How to block it?

Solution
So far I was writing custom filters manually. With Firebug I could analyze the source code of any element. Then I added an Adblock Plus custom filter based on the previously discovered HTML source.

But there is a better way! Use Element Hiding Helper (EHH), which is a companion extension for Adblock Plus meant to make creating element hiding rules easier. Visit the link for a short guide.

Tips
You can switch the preview on/off, which is a great way to see if you block the correct element. If you use Vimperator, you might want to disable its shortcuts with Shift + Esc to be able to use EHH’s own shortcuts.

Update (20120220)
I installed this add-on on another machine but the ABP icon didn’t appear. On the bar I made a right click -> Customize…, but the icon was not there either. Solution: right click on the bar and enable the Add-on Bar. It will appear at the bottom. As it disturbed me, after using the EHH I disabled the Add-on Bar.

_{Thanks Yves for the tip!}

Copy the URL and the title of the current web page to the clipboard

The following tips are from the post “My vimperator settings“, but they are somewhat hidden in the text :)

So, when browsing, a common task is to get the address or the title of the current web page. Getting the address is easy, but for the title we need to consult the page source. How to get these data painlessly and copy them to the clipboard?

Steps:

• Visit the post “My vimperator settings” and install vimperator + my config file.
• For copying the URL address, use the command “y”.
• For copying the title of the page, use the command “ALT + y”.
