Firefox sidebar causes extreme logging on some pages, leading to a noticeable performance issue

[MTRNord]

Hi I am using promnesia for firefox and in the chat app develop.element.io specifically I am getting lots and lots of logs which seems to not only cause UI blocking for the tab but also quite a high memory usage. I confirmed that turning off promnseia fixes the performance issues, which is why I think this may be a bug here.

There is an endless stream of these logs happening. It seems to specifically only be an issue with this page for reasons I dont get currently.

I am happy to provide any more info needed to debug this :)

The log seems to originate from https://github.com/karlicoss/promnesia/blob/master/extension/src/sidebar.js#L392

I think this is related to #177 and #307

If you want to ignore the site for now, you can right click the promnesia icon and click 'exclude globally'

For example if the page was

https://example.somesite.com/page

You could ignore that in particular, or use a regex (start end with /, like): /example.somsite.com/*/

These can be edited in the extension preferences as well

Thanks I will give that a try :) It indeed sounds related.

I think it's not necessarily caused by #177 or #307 -- even with single update from the background page it takes it a while to process highlights. I wonder if the algorithm needs a bit of a speedup (although still crazy that it takes it more than a second for a single pass)
