Addon slows down Firefox start significantly #409

Open jmozmoz opened 5 years ago

jmozmoz commented 5 years ago

Usually, I have open a lot of tab (>100, perhaps >1000). At fresh start of Firefox, it will take nearly a minute until any user interaction with Firefox is possible if this addon is installed. (Actually, the same hapens with other addons like Tree Style Tab installed)

Is there any chance to avoid blocking the user interface?

I had the same problem months ago. As a workaround, you can simply put "always" in the compact mode preference. It seem that if you stay with "dynamic", the pages thumbnails are always generated, even if the compact mode is displayed, and in a result that slowdown dramatically firefox if you have many tabs open.

This does not seem to work. I have set compact mode to always.
