扩展启动一段时间后，内存占用飙高

[twio142]

扩展刚启动时占用内存仅 20+ MB，但几天后会发现飙高到 400+ MB，甚至期间并没使用过扩展。

Chrome: 99.0
RSSHub Radar: v1.7.0

Need more debug info:

• chrome://process-internals/#web-contents
• 
• chrome://extensions/?id=kefjpfngnndepjbopdmoebkipbgkggaa -> click background.html -> switch to the Console tab

我也遇到了这个问题

另外，我安装了 workona 标签管理插件并启用了其中的休眠功能（一段时间不使用的标签页会进入休眠），不知道是否与报错有关

[twio142]

我也有使用标签页定时休眠的插件。另外我发现每当打开新标签页（chrome://newtab）就会报错 Failed to construct 'URL': Invalid URL 和 Cannot read properties of undefined (reading 'length')

使用休眠标签导致内存异常的可以试试右键标签改了。

Invalid URL errors are fixed in cf15a0a, but I'm not sure if it caused the memory leak

[twio142]

The leak still exists with v1.10.1... Now I’m receiving Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.

This problem still exists.

RSSHub Radar: 1.10.1

Same issue on version v2.0.6
Chrome: 120.0.6099.109 (x86_64)

[DIYgod]

I speculate that the memory leak in the v2 version is caused by console.debug. I have removed all console.x at here. Please observe if v2.0.7 still has any memory issues.

[DIYgod]

In version 2.0.7, the memory consumption is still high, but the background service worker and offscreen.html memory usage seems to be normal. I'm unsure about the exact cause of the problem.

[aur3l14no]

Sharing a workaround: I remove the permission "access to all pages" so that the extension is only activated when I click on it. Seems to be smoother now.

I further debugged and found that the memory leak may be caused by DOMParser. Then I found a stackoverflow post confirming my guess, so I removed DOMParser in this commit, hoping this will solve the problem. 653f0db
