Here are a few keyboard shortcuts for Firefox to mark the release of version 3 of that browser (which I express my initial opinions about at the bottom of this post). These should all work in Windows and Linux, for Apple Macs simply substitute the Ctrl key with the Cmd key.
Full screen mode
To hide the menus, toolbars and status bar press the F11 key, press it again to go back to windowed mode.
Text Size
To increase the size of text on a page, either hold down the Ctrl and press the + key or, if you have a wheel mouse, hold down Ctrl and roll the wheel upwards. Unsurprisingly, to decrease the size of text on a page, either hold down the Ctrl and press the - key or, if you have a wheel mouse, hold down Ctrl and roll the wheel downwards. To restore the text size to normal hold down Ctrl and press 0 (zero).
Select the search box
To move the cursor to the search box, either the built in one or the first one on a toolbar, hold down Ctrl and press K (I am not sure of the significance of K here - so probably not that easy to remember)
I have already published posts that detailed other keyboard shortcuts for Firefox:
Quickly open link in a new tab - without losing focus on current tab
Opening the Find box - near the bottom of this general post
A previous selection of shortcuts - for navigating between tabs, opening new tabs, closing tabs, opening bookmarks and selecting the address bar.
How to refresh the page
My initial feelings about version 3
I have been using Firefox v3 for a few days now and don't have much to report. It has crashed twice in that time, but the 'Restore last session' feature means that this is not such a disaster. It does not seem particularly quicker and I have yet to find any new features that have excited me. On the downside it still seems to 'Not respond' a little too often and memory management is still far from perfect.
For Entrecard users there is a problem with the way that it handles cookies. If you switch between Entrecard accounts you will keep being told to login again. I have posted a workaround solution on the Entrecard forums here - rest assured the boffins at ecard are working on it.
