只需安装不同的 Firefox 版本,选择不同的安装目录即可。如果指定
-no-remote 命令行选项
。在这种情况下,您至少需要两个浏览器配置文件。
至于 Chrome,通常不支持比当前版本更旧的版本 - 理论上没有人应该运行它们。 Chrome 还对并行使用多个浏览器版本的支持非常有限。如果您除了稳定版本之外还想拥有 beta/dev 版本,那么Google Chrome 便携版应该是你最好的选择。
编辑:实际上,我尝试使用 Google Chrome Portable,但它并不是一个完美的解决方案 - 更新不起作用,因此即使便携式版本跟上 Google 的发布速度,您也必须定期重新安装它。最后这个答案似乎是最好的解决方案 - Chrome 安装在用户帐户中,以便您可以为其他 Chrome 版本创建其他帐户。 Windows 允许在不关闭会话的情况下切换到这些帐户,因此情况并不像听起来那么糟糕。
Simply install different Firefox versions, choosing a different installation directory is sufficient. You can run them in parallel if you specify the
-no-remote
command line option. In that case you need at least two browser profiles however.As to Chrome, versions older than the current release are generally not supported - in theory nobody should be running them. Chrome also has very limited support for using multiple browser versions in parallel. If you want to have the beta/dev version in addition to the stable version then Google Chrome Portable should be your best option.
Edit: Actually, I tried using Google Chrome Portable and it is everything but a perfect solution - updates don't work so you will have to reinstall it regularly even if the portable builds keep up with Google's release pace. In the end this answer seems to be the best solution - Chrome installs in the user account so you can create additional accounts for other Chrome versions. Windows allows switching to these accounts without shutting down your session so it isn't quite as bad as it sounds.
不,没有这样的功能(至少在 Firefox 中,我对 chrome 不是 100% 确定),但也许像 browsershots.org 帮助你。
您可以在其上发布一个网址,该网站会在许多不同的浏览器中进行屏幕截图,因此您可以看到布局问题(但请注意,您无法通过这种方式测试功能)。
no, theres no such function (in firefox at least, im not 100% sure about chrome), but maybe something like browsershots.org helps you out.
on it you can post an url and the site makes screenshots in a lot of different browsers, so you can see layout problems (but note that you cant test functionality this way).
