Achoo looks like a cool extension but I get much more use with Web Inspector. It's about the same developer console on the desktop.

Edit: the theme follows whatever your system settings is.

You likely won't find a solution. So, opening that file, the browser is going to read the entire file and convert the HTML into memory structures. It will then parse those structures and compute / render them as text / widgets / components on a browser canvas. This works well for small HTML documents, but 500MB is likely too much to handle as you - very likely - hit memory limits. (Rendering 500MB of HTML likely expands to a factor of that in terms of memory usage) So, you need to consider alternatives. That tool mentions the SQLite3 db file that's used as a source to generate the file. You could just open that and query the data by hand with SQL SELECT queries, using a command line tool. Or whip up a quick Python script. You could open that SQLite file using OpenRefine which makes querying easier without too much hassle. https://openrefine.org/ You could split the HTML file in smaller chunks using the "split" command, fix the HTML of each chunk so you can open each file separately. The trouble is that you need to fix / finish the HTML of each chunk manually and navigating across files is clunky. More involved, and depending on how technically inclined you are: You could setup a PostgreSQL instance and import / load the SQLite file into PostgreSQL database. The benefit is that you're now using a fully fledged database solution. Or you could load the SQLite data into an ElasticSearch instance, and query the data in the ES index using Kibana. The hard part in all these solutions is that you'll be looking at raw data. So, you won't see threads and nested comments or you will have to follow keys and identifiers. The big issue with the HTML from the original tool is that it contains all the data at once. An alternative would be a JavaScript based solution which dynamically queries the SQLite database - sending chunks to the browser - as you navigate through the channel. Then again, building that is labour intensive, so not something you want to do yourself. You could consider pinging the author of the tool and ask them how to proceed. But since the docs hint towards using the SQlite data, I wouldn't put up high hopes. More on reddit.com
