Comment 26 for bug 20765

If you can, test your URL with IE (or other browser) before commenting. Also, see Bug 277547 if your cpu has hyperthreading or multiple cpu.

It has been suggested that this bug be closed WFM because
a) Alexsey the confirmer states his/her problem was 'history' (so it should not have been confirmed at that time)
b) the bug is digressing into problems with other links and issues (some of which are not limited to unix)
c) several unanswered questions related to mseele's report using the initial URL:
   - does it happen if just clicked (rather than middle clicked)
   - does it happen with FF 1.5 or trunk
   - does it happen just with linux
   - does it happen of not using tabs

Perhaps it is wise to close the bug and address individual issues (causes) in new bugs focused on specific issues or in one of the many existing bugs https://bugzilla.mozilla.org/buglist.cgi?query_format=advanced&short_desc_type=anywords&short_desc=perf+performance+slow+cpu+high+freeze+freezes&product=Core&product=Firefox&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&resolution=---&op_sys=Linux&chfieldto=Now&field0-0-0=short_desc&type0-0-0=notsubstring&value0-0-0=mail

If nothing else, assuming this is a linux only bug, then examples that fail in windows and other OS don't help this bug - and should be taken elsewhere. Complexity and complex example sites also make finding the cause more difficult. A developer is probably not going to touch this unless the problem can be reduced.

Bug 248345 suffers similar issues. Still, Linux users might want to check it.
