hi yongqli, if you have any questions about add-on support for multiprocess Firefox (e10s), just drop by the #e10s IRC channel on irc.mozilla.org. MDN also has a good introduction:

In bug 1083545, Achwaq says that the FastestFox addon causes Firefox to take 10x longer to start!

Comment 3

[Chris Peterson [:cpeterson]]

Achwaq, do you have any other addons installed? The FastestFox addon does seem to slow down page loading, but it does not make my Firefox start 10x slower.

Yes Chris i do have some other addons installed, and after trial and error approach i found out that this combination (Adblock Plus + Fastesfox) will render the browsing experience with e10s painful, by the way the start-up slowdown is affecting the browser even if e10s is disabled

[Chris Peterson [:cpeterson]]

Achwaq, so with Adblock Plus + FastestFox enabled, *both* start-up and browsing are painfully slow with e10s enabled, but *only* start-up is slow (and not browsing) when e10s is disabled? If trying to figure out whether this is an e10s bug or just a performance bug unrelated to e10s.

Here is the summary Chris assuming that fastesfox is always enabled:

With e10s enabled + adblock plus: Really slow start-up time + Slow browsing experience (fastestfox in general is not compatible, not all the features are working like the popup bubble)

With e10s enabled: no impact on start up time + slow browsing experience (fastesfox still not compatible)

With e10s disabled + Adblock: Really slow start-up time + after waiting for my 4 pinned tabs to load now every newly opened tab will take as much time as the startup time

With e10s disabled: normal start-up time + normal browsing experience

Conclusion:

1 - There is a compatibility problem between Adblock plus & fastestfox
2 - fastestfox in general is not compatible with e10s

The developer has been contacted through AMO.

This still does not appear to be working. I didn't experience any slowdown though.

[Achwaq Khalid]

the addon itself is no longer working even in non e10s mode
