About this page  § 

2010-05 I found a reproducible bug with the Firefox add-on Multi Links version 2.0.0.17 using Firefox 3.6.3.

Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.9.2) Gecko/20100305 Unity/1.9.2-0.1 (2010) Firefox/3.6.3

Since I no longer had the link to the original content, 2010-05-14 I decided to make this page.

Steps To Reproduce  § 

1. Reboot
2. Start Firefox with firefox -safe-mode
3. Select [x] Disable all add-ons
4. Click <Make Changes and Restart>
5. Go to Tools > AddOns, and enable Multi Links
6. Restart Firefox
7. Visit any extremely large page with mixed text, pictures and images. This issue is most visible the larger the tab's content is.
   1. The test page
8. Click and drag your box.

Notice the long delay when drawing it.

I am unable to reproduce my original test:

1. Open a link in a new tab, in the background. For example, middle-click a thumbnail.
   1. Test link: Index
2. Try to scroll up and down while the tab is loading in the background.

What is seen is a horribly sticky scroll with delays of over 5 seconds. Presumably a faster computer would reduce this speed limit.

Reproduced on a 2Ghz single-core, with my CPU usage spiking to 100%. While some other software was running and using some CPU cycles, there wasn't anything notible about any other software.

Workarounds  § 

No workaround is known. However, Snap Links Plus is an alternate add-on which accomplishes the same thing: addons.mozilla.org/en-US/firefox/addon/116390

It has been tested and works without the above issue.
