502209 - shift+reload causes significant slowdown on google maps

Status: RESOLVED DUPLICATE of bug 497665

(Firefox :: General, defect)

Description

[Mark Hagger]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.9.1) Gecko/20090630 Fedora/3.5-1.fc11 Firefox/3.5
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.9.1) Gecko/20090630 Fedora/3.5-1.fc11 Firefox/3.5

If I look at the marker demo as in the url above all is well.  Then try a shift+reload in the usual way to clear the cache and reload the page (a typical scenario for someone developing a new mashup for example).

Markers are now drawn on the page by a very very slow snail, who appears to be mostly asleep.  Press <enter> in the url bar, to effectively reload the page, and the snail vanishes to be replaced by a super fast hare again.  Odd.



Reproducible: Always

Steps to Reproduce:
1. Go to specified url, view markers in fast mode
2. Use shift+reload, view markers in ultra slow mode
3. Press <enter> in the url bar, view markers in fast mode again
Actual Results:  
Extreme performance changes.

Expected Results:  
Consistent speed across uses of shift+reload, as per older versions of firefox.

The exact same behaviour has been seen on Firefox 3.5 on Windows XP as well.
