Re: NVDA 2018.4 Beta 2: Improved Responsiveness in Mozilla Thunderbird

David Goldfield


Your advice regarding the use of add-ons as a possible cause for slower responsiveness was worth pursuing as I do use several add-ons, including the Mozilla enhancements add-on which you mentioned. Per your advice I disabled every add-on which was running, restarted NVDA, and compared 2018.4 beta 2 with 2018.3.2, both of which had all add-ons disabled. There is still a slightly noticeable difference between 2018.4 Beta 2 and 2018.3.2. It is not as bad as it was in beta 1 but it is somewhat noticeable. Again, this is when I navigate through links in a message in Thunderbird by pressing K or shift-K. 2018.3.2 is incredibly snappy but beta 2 has a slightly noticeable lag. I am using Espeak. I did upgrade to Windows 10 build 1809; this shouldn't matter but I thought I'd mention it because it could well be important. What can I do or what logs can I send to you which might help you to figure out what I am hearing?

Hi David,

I can't notice much difference - it seems pretty snappy in all three versions (2018.3.2, beta1 and beta2).  Are you using an add-on like the Mozilla app enhancements which might affect responsiveness?

If you might be, if you press NVDA+q, then down arrow to "restart with add-ons disabled" and press ENTER, you can check what it is like without any add-ons.  If that is much snappier, you could first check for updates to any addons you use - Joseph Lee particularly regularly releases updates to his add-ons which often improve performance.

Otherwise, if you could send me a copy of your log at input / output or debug level, I can see if I can find anything slowing you down.

Last week I mentioned that NVDA 2018.4 beta 1 was exhibiting slower responsiveness with certain keypresses. This was noticed in Thunderbird but also in Google Chrome, two programs which I use daily. I'm happy to report that this situation has improved and the responsiveness is much better in beta 2. However, the 2018.3.2 production build still seems snappier regarding the time it takes me to press a key until I hear the output or results of that press. I most notice this when navigating by links using K or shift-K. I'm very pleased that things have improved with beta 2 but I do hope that the final 2018.4 release will behave identically to 2018.3.2. Could someone from NV Access comment on this? Were changes made to NVDA which could, potentially, increase latency with key presses?
