Firefox Tips & Tweaks

[Mortis]

Prevent sites from disabling the context menu
Some sites prevent you from right-clicking on the page to show the context menu. To disable such attempts, go to Tools > Options... (Edit > Preferences... under Linux and Mac OS X), click the Content section, and then click the Advanced... button next to Enable JavaScript. In the Advanced JavaScript Settings window, uncheck Disable or replace context menus and click OK.

For these modifications to work, enter them in you userChrome.css file located in your profile folder. The userChrome.css file does not exist by default and has to be created in the folder "chrome".

/* Change the progress bar color */

Code: Select all

.progress-bar {
-moz-appearance: none !important;
background-color: #660000 !important;
}

/* Display the sidebar in opposite side */

Code: Select all

#browser {
-moz-box-direction: reverse;
}


These changes are done in about:config
Hiding the Go button in the URL bar
browser.urlbar.hideGoButton [default false] can be set to "true" by double-clicking the entry.

A very, very useful feature that I didn't know existed (and thought was sorely missing from the application) is that you actually can drag and drop folders to change their positions in the bookmarks drop-down menu/bookmarks toolbar by pressing either Shift or Alt when dragging.

[Mortis]

about:config -> browser.tabs.closeButtons

• 0: Close button on the active tab
• 1: Close buttons on all tabs (default)
• 2: No close buttons
• 3: Display one close button at the end of the tab bar (Firefox 1).

I don't know about you but I was getting really annoyed about the crippled interface the default Google interface firefox gives you when pressing enter in the search box to quickly access the search engine. So I managed to dig up a way to change the url firefox uses.
Go to your firefox install direcotry. There you should find a folder named searchplugins. The files inside the folder contain the settings for all the search engines you have installed. Now open google.xml in your preferred text editor and find a line stating

<SearchForm>http://www.google.com/firefox</SearchForm>

and change it to

<SearchForm>http://www.google.com/</SearchForm>

Now nothing prevents you from fully enjoying your Google

Here at mozillaZine is a very interesting thread regarding the newly implemented bilinearly filtered image zoom in Firefox 3. It has been a hot potato in the pixel arts/game graphics community, where the filtering effectively breaks websites based on zooming (read: all websites). People have also criticized the picture quality achieved through the method at the moment.

There is a bug reported here, too, will be interesting to see if anything gets done soon!

browser.download.manager.scanWhenDone -> Set value to false in about:config if you're annoyed by Firefox 3 scanning your files.

You can defragment your Places in Firefox 3.5:

Open the Error Console (Tools->Error Console)
In the Code textbox, paste this single line:

Code: Select all

Components.classes["@mozilla.org/browser/nav-history-service;1"].getService(Components.interfaces.nsPIPlacesDatabase).DBConnection.executeSimpleSQL("VACUUM");

Press Evaluate.

In about:config, you can modify the add-on install wait time with

Code: Select all

security.dialog_enable_delay

It's in milliseconds. 0 is nada.

Not digging how closing your last tab in a window also closes the window?

Code: Select all

about:config -> browser.tabs.closeWindowWithLastTab -> set to "false"

[Mortis]

Increase the amount of remembered recently closed tabs:

Code: Select all

browser.sessionstore.max_tabs_undo

Firefox 3.6 comes with Flock-style tabs where related tabs open next to the parent tab.

Code: Select all

browser.tabs.insertRelatedAfterCurrent

[Mortis]

Shift+Ctrl+T reopens your last closed tab!

Firefox 3.6 finally comes with the ability for web designers to select the preferred resizing algorithm for Firefox on a per-site basis in-between Nearest Neighbor, Bilinear Filtering and Bicubic Blur. With earlier versions of Firefox, pixel art would be hopelessly blurred up when you would resize an image.

Most pixel art websites will have covered this by the time of the release of 3.6, but if you want to make sure you get all your pixel art images resized the way you dig, here's how: Insert userContent.css into Application Data\Mozilla\Firefox\Profiles\[profile]\chrome

Code: Select all

img[src$=".gif"] {
image-rendering: -moz-crisp-edges; -ms-interpolation-mode: nearest-neighbor;
}

img[src$=".png"] {
image-rendering: -moz-crisp-edges; -ms-interpolation-mode: nearest-neighbor;
}

What the above does is resizes .gif and .png images always with NN

If you use a lot of add-ons, their entries can pile up in your about:config. You can best find out what kind of entries add-ons have added to your about:config registry by sorting them all based on their status, "user set". That way Firefox lists first entries that have been changed/added to it.

I mention this because I solved the rather common but extremely elusive "unresponsive script" javascript issue by simply uninstalling Smooth-Wheel, deleting its settings (choosing "Reset" for an entry is enough for Firefox to delete it after restart) and reinstalling the add-on.

A more straightforward method still would be simply to delete lines from your prefs.js file in your profile folder.

If you're frustrated - like I am - with sites still using JavaScript to pop up windows instead of tabs, you can force Firefox to open them in new tabs with these settings:

Code: Select all

browser.link.open_newwindow 3
browser.link.open_newwindow.restriction 0
