Based on my previous post, iFrame bookmarklet, with added capability to resize and move the iFrame
Try Opera, and try my extension :)
Update Version 0.6-0.7: After 3+ years, I finally found the time to edit this extension to work with the new version of Opera (Chromium). Tested and Published for Opera 39. I don't know how many will actually come back and reuse this extension, but well, at least I'm using it extensively myself :)
Update Version 0.2: Added an Option Page and Toolbar button to enable/disable, hover with Ctrl key, and show Tiny Box link or directly show the iFrame link preview
Update Version 0.3: Added Tiny Boxes for easy moving and resizing iFrame
Update Version 0.4: Added Options for Ctrl/Alt/Shift Key combination and Show/Hide Toolbar Button
Update Version 0.5: Added Options for Custom Size and Position,
also a feature to display search result of selected text in iFrame :) Love it!
Too bad Google search could not be opened in an iFrame.
