1411989 - faulty development process leads to unusable firefox due to slowness

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[charles-t-mozilla]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/602.4.8 (KHTML, like Gecko) Version/10.0.3 Safari/602.4.8

Steps to reproduce:

Use firefox on any desktop or laptop machine for mac os x.


Actual results:

Developers added features with out checking to see if it would make the browser unusable on a average platform. After each upgrade firefox gets very noticeably slower and slower until it just spins and does nothing. The result is that users, likely millions of them become frustrated and gravitate to other browsers by uninstalling and or not recommending to install firefox. Removing profiles, reinstalling are all ineffective. Current solution is to uninstall firefox and use another browser.


Expected results:

Developers should have benchmarks that reflect typical usage of a browser to detect when a release becomes unbearable and unpleasant to use. This would result in at best marginal decrease in speed or better yet improvement in speed. Resulting in people keeping firefox installed.

Not a bug report. Mozilla uses many tests and benchmarks by the way. Most of stability issues and slowness are due to extensions.

The issues me and others have seen are with browsers with no extensions and profile data. This means that extensions are either enabled that are not listed in the extensions folder or your benchmarks are not doing a good job. Perhaps your benchmarks should include the most commonly installed extensions.


I see 54 bugs reported with the keyword "slow" in the past year. There is 34 in the previous year and 30 in the year before that. It's not clear how many of those where caught by tests and benchmarks, though I suspect that this is a growing trend.
