MeasureIt 0.4.8 (Firefox 4 compatible) is a great app for web designers as they can measure anything in their browser frame with the ruler. MeasureIt for Firefox adds a toolbar button with which you can draw a ruler on screen and measure height or width of any component that is in your browser frame.

How to run MeasureIt in Firefox 4

I installed MeasureIt on Firefox 4, but couldn’t locate the button. It installed correctly but MeasureIt disappeared after it installed. Some experimentation lead me to a solution that I thought would be worth sharing for those who have MeasureIt missing issues.

Step 1: Install MeasureIt-0.4.8-fx.xpi and restart your browser

Step 2: Enable the Firefox 4 add-on bar (if you want MeasureIt button to be shown on Status bar / add-on bar)

Step 3: Right click on add-on bar and click “Customize…”

Step 4: Locate the MeasureIt button and drag it to the location where you want it to be shown.

MeasureIt-Firefox4

Step 5: Click on MeasureIt button and start measuring.

Oh and in case you didn’t know, you can run Firefox 4 and Firefox 3 simultaneously and install separate extensions for both.

How to Run Firefox 4 and 3 Simultaneously [Side by Side] with Firefox Profiles

Mozilla has just released Firefox 4 RC for download. I won’t be surprised if you want to run Firefox 4 and 3 simultaneously. Fortunately, there’s a workaround that lets you run Firefox 4 and 3 side by side. All you have to do is to assign a different profile to either of 2 Firefox versions and you’re done.

Here’s the guide:

How to Run Firefox 4 and 3 Simultaneously

Important: We’re assuming you have Firefox 3 installed. Now you got to install Firefox 4 at a different location.

Step 1: Download Firefox 4 RC and launch the setup

Step 2: Opt for “Custom” installation option and click Next

Firefox 4 Custom Setup

Step 3: When it asks for Destination Folder, specify a different path, for example:

C:\Program Files (x86)\Mozilla Firefox 4

Firefox 4 installation path

It’s because Firefox 3.6 would be installed in default path: C:\Program Files (x86)\Mozilla Firefox.

Step 4: Click Next and install the Firefox.

When installation completes:

Step 5: Press Window key + R to open the Run menu, type this:

C:\Program Files (x86)\Mozilla Firefox\firefox.exe -p -no-remote

Firefox.exe -p -no-remote

This will open Firefox Profile Manager that will allow you to add / remove Firefox Profiles.

Step 6: Create a new Profile and name it (I named it FF4). It’s also recommended to rename the default profile, I renamed it to FF3.

Firefox Profile Manager

Step 7: Create Desktop shortcuts for both Firefox 3 and Firefox 4.

Step 8: Right click on Firefox 4 shortcut and click on Properties.

Step 9: In the Target field, add this text at the end:

-p FF4 -no-remote

FF4 = name of the profile.

See the screenshot below for help.

Firefox Shortcut

Now click OK.

Now when FF4 profile has been assigned to Firefox 4, you need to assign FF3 profile to Firefox 3.

Step 10: Repeat the steps 8 and 9 for Firefox 3 shortcut.

That’s it. Now you can run Firefox 4 and Firefox 3 simultaneously, side by side. To test it, click on both of the shortcuts one by one. You will notice that 2 Firefox windows will open. Here is the video guide, if you need any further help:

I’m using Firefox 3.6.15 and Firefox 4 RC1!

How to Install Incompatible Extensions and Themes for Firefox

FirefoxIt’s sometimes important to know how to install a Firefox theme or extension that is not compatible with current version of Firefox since it was made for an older version and developers didn’t bother to upgrade it to work with latest version of Firefox. There have been many solutions to put an expired extension of Firefox to work will all versions of the browsers; however I failed to find a way to install an incompatible extension or theme for Firefox. If an extension or theme is incompatible with current version for Firefox, “Add to Firefox” button will be disabled hence you will not be able to install that add on, instead Firefox will say “This add-on is for older versions of Firefox”. Did you know how to bypass Firefox version compatibility test? Probably no, but it’s simple to work the other way around, let’s see how. Follow these steps and install any theme and extension for any version of Firefox whether or not they are compatible:

  1. Install Nightly Tester Tools extension for Firefox
  2. Select the theme or extension you want to install and go it its page, e.g. https://addons.mozilla.org/en-US/firefox/addon/13232
  3. Copy this URL and open it in any other browser: IE, Google Chrome, Safari or Opera
  4. You will see “Download Now” button, right click on it and copy link address:Naver in Opera
  5. Now go to Firefox and Paste the copied link address which will look like this: https://addons.mozilla.org/en-US/firefox/downloads/latest/13232/platform:5/addon-13232-latest.xpi?src=addondetail
  6. Hit Enter/Return and plugin install window will open:Naver Install
  7. Install the Theme/Extension

    8. When installation completes it warns you that this add on was not compatible with current version of Firefox.

  8. Click “Force Install”, it shows following window:Naver Force Install
  9. Restart Firefox and you’re all set.Naver Restart

In case you want to put incompatible, installed extension or theme to work, read on.

To Install Incompatible Extension or Theme for Firefox:

To enable existing incompatible extensions and themes for Firefox:

  1. Go to Tools>Add ons
  2. Note that there will be button “Override all Compatibility” that enables all extensions
  3. If you want a single incompatible add on to work, right click it and select “Override Compatibility”
  4. Click “Force Install” and its enabled.

NOTE: Firefox doesn’t recommend using incompatible extensions and themes so you may try this at your own risk. Sometimes it works but sometimes it may result in crashes or problems with working of Firefox.
