As the number of downloads increases, chromium starts behaving badly - Bong - 01-12-2025
I use plug-ins that can be used to download all the pdfs, images, mpgs, ... in a web tree. This can lead to a large number of downloads when I don't specify a good pattern. As the number of downloads goes up, clearing the download data takes longer and longer as does shutting down and starting up (I started Cent and it took 23 minutes before I could actually use the browser). I have seen this behavior in other chromium-based browsers so I think it is a fault in the chromium engine.
My question/enhancement would be to have a limit to the number of items in the download area where as a download is added to the history file, the oldest download is removed if there are more than the limit.
I am using version 5.1.1130.129 of Cent.

Found out it's much faster to just uninstall Cent and re-install, re-customize, add plugins, ... than to actually try to handle the download issue.

oh yeah, and one more thing, you can use third party downloaders like IDM
it will grab downloads and they will not be saved in history

This will cause Cent to become "not responding" for many minutes (up to 25 if download list is > 10K)

How long did it take you to accumulate 10K+ downloads?
For now Chromium keeps only 90 days of history, but there is no limit on downloads, which means that downloads can be accumulated indefinitely.
By the way, we have a wiping feature(Main menu -> Help -> Wipe browsing data) can be used to deep clean User Data.

Found a work around. Delete the downhistory via the settings/privacy tab. Kill Cent, closing it down gracefully will take forever. del ...\AppData\Local\CentBrowser\User Data\Default\History and the restart. Whatever is causing the issue, it has to do with that file. It's acting like it is deleting a single entry and then re-writing the entire file, then deleting 1 more entry and then rewriting the file, ...
To answer the question by Admini, about how long does it take to get a large download history, it depends on what is being done. One guy is trying to work on making a better artwork AI, so he will go to a web site (or a search page) and tell a plugin to download all the images meeting a specification so he can hit 10K in a couple of hours. Just browsing the internet, I think it would take forever to download 10K.

Yes, download records are written into this file.
You can write a batch script to delete it.

I've collected some patches for other chromium based browsers that continue to support the Manifest V2 extension.
1. ungoogled-chromium extensions-manifestv2.patch
2. supermium manifest_v2_experiment_manager.h
3. brave
brave-core/chromium_src/extensions/common/extension_features.cc
4. cromite Override-the-MV2-deprecation.patch
I hope it's helpful to you.

By the way, I still hope that the new version of the cent browser can customize the icon of the js bookmark , and customize the font color of the js bookmark.
If it is too troublesome, a simple solution is: you can put the icon into the chrome_100_percent.pak file and package it.
When I use it myself, I use the chrome-pak-customizer tool to unpack chrome_100_percent.pak, then find the js bookmark icon and replace it with the custom icon.
That's it. Pretty simple, isn't it? If it is convenient for you, you can even tell me the file name of the js bookmark icon so that I can find it quickly
Finally, thanks for all your hard work and good luck with you and the cent browser!
