Re: regression with adobe flash


Gene
 

That assumption is usually wrong.  At times, an add on may cause a problem in performance of some sort but add ons are just small bits of code that, in most cases, do nothing or almost nothing unless the user takes an action that gets them to do something or unless they are intended to be generally active such as an add on to add a certain synthesizer to NVDA.  In that case, of course, the add on is always active when the synthesizer is in use.  But add ons should not affect adversely, performance of programs in general.  Even if an add on monitors the activity in a program and automatically does something when wanted or needed, modern computers are so fast that the activity of the add on uses such a tiny amount of the capacity of the computer that any possible slowing of performance is so tiny that it is unnoticeable. 
 
If add ons adversely affected performance, they wouldn't be as popular as they are.  One reason people use Firefox, for example, is because of the great number of add ons they have to choose from when deciding if they want to add features or functions.  A large number of NVDA users use add ons as well.
 
Without good reasons, such as reports from a number of reliable users or observations you make yourself, often in more than one situation, of a problem or idea about how something affects performance, assumptions should not be made.  They are unsupported and may lead, as in this case, to needlessly not getting benefits or advantages that are available.

i know that its safe to install addons from the original sites.
but i prefer that use only programs not addons.
i am sure that the main program without addons are more fast, stable
and reliable.
