sometimes at work I notice a lag in tab closing,
I mean it takes a bit till the tab disappears completely from the screen,
could it related to hardware acceleration?

my graphics card is intel® hd graphics and I read your post in another thread that 
hardware acceleration doesn't make any difference on a bit older machines or 
machines with embedded graphics card

anyway, I disabled it and I think there's some improvement

CentBrowser's private tab makes it one of the best private browsers around, but it could be so much better! 
Now the logins, passwords and other settings are lost every time you close a private tab.
Instead, why not open each domain in its own private tab?  You want to keep the information, with the option to purge 3rd party cookies. 
That way the information would be private, and persistent. 

even though I've got chrome://flags/#omnibox-ui-max-autocomplete-matches set at 12 (max),
it doesn't work, I only get 3 bookmark suggestions on the address bar,
I don't think it's a cent issue, but I thought about asking here,
does anyone know if there's a way to make it work?

OK, first of all I do not use all these extensions at once. Most of them stays disabled. I only enable them when needed. First few are the ones I regularly use.

請問32位元跟64位元 cent browser 
除了對應windows作業系統32位64位外
2者在性能,穩定 或其他方面有何優缺點?

假如先裝了32位元 cent browser 
保存各項設定和個人化的User Data資料夾
可以移動到後來裝的64位元 cent browser 裡嗎?

也就是User Data資料夾 32位元跟64位元 cent browser 通用嗎?

很奇妙，我下载设置的默认到D盘的一个文件夹，结果下完都跑C盘downloads去了（内置下载，文件夹显示的也是D盘的），然后我试了下另存为，是在C盘downloads。
然后我把这个改到D盘，再试内置下载就好了
3.9.2.45 64位版本
win 10 1803

Steps to reproduce:

1a. Start the browser with the --force-renderer-accessibility command line argument
OR
1b. Start the browser norlmally and open chrome://accessibility and enable the "Native accessibility API support" and "Web accessibility" checkboxes

(What for? - Some applications use the IAccessible API to obtain the URL and other information. This API is supported by various browsers, but it is disabled by default in the Chromium, starting with the version 69.)

2. Open the settings page: chrome://settings
Or try to clear the browsing data (via Ctrl+Shift+Del)

Notice, that the page opens pretty slowly.

For comparison, the version 3.7.2.33 of the Cent Browser did't have this problem.

Hello! I use the Cent Browser on Windows and I believe that this is the best solution at the moment. Will you port it for macOS?

First of all, deeply thank for this great browser. I missed a lot of Fast Video Downloader in Slimjet since I switched to CentBrowser from Slimjet last Spring. Just wonder if you could also integrate it in CentBrowser. Otherwise, wonder if there is a Chrome extension of similar functionality. Thanks!

Please add ability to make tabs scrolling more slowly.
It can be difficult to navigate among tabs, when one step of the mouse wheel moves them too far away.
