When reporting a bug, please include as many of these as possible:
Operating System you are using android 9
Tor Browser version alpha 115.2.1-beta (13.5a5) (Build #2016005097), 309b109f347b
Tor Browser Security Level default
Step by step of how you got to the issue, so we can reproduce it (e.g. I opened the browser, typed a url, clicked on (i) icon, then my browser crashed)
I pointed this issue out to a Tor Project android dev, so hopefully they can help. Thanks for the report of the crashing and hopefully they can replicate - still not sure what you mean by clicking an i icon - and this may happen with any addon
As for addons, we do not recommend adding any to Tor Browser, and we should make it more obvious and actually recommend to NOT add extensions that aren’t pre-bundled. The reason is they can alter your fingerprint and compromise security and your anonymity
may be explicitily inform about addons in very simple language, like, “as of now we cant stop you from downloading, installing addon, however, they will never work”
